Canoe Rodholder Challenge

We challenge you to design a new rod holder for Trapper Canoes.

Fishing is an activity that so many of us enjoy! Outdoor sports fans know that a universal fishing rod holder would be a big help when you and your friends are out on the water.

Trapper Canoes wants to provide an eco-friendly option for their nature-loving, fishing community. The rod holder you create should be made of environmentally friendly and recyclable materials like wood, cork, natural fabric, biological resin, leather, or metal. If you'd like to propose a different material, just ask!

Your design needs to include: the mounting system to the canoe, the rotating system for the rod holder and the rod holder itself. Trapper wants very simple ideas but very creative additions outside these three main components may be considered.

Your mounting system should allow the rod holder to be moved along the edge of the canoe (see pictures and specifications). The canoe should not be damaged in any way when changing positions of the rod holder (no drilled holes, etc.)

The rod holder must be usable with different types of rods. Let's keep this solution universal! Allow for adjustments to the angle between the length of the canoe and the rod, too.

Winning designs should be universal, environmentally friendly, manufacturable, easy to use, and match the Trapper Canoes brand (Go to

Requirements

  • Use eco-friendly materials in your design: wood, cork, natural fabrics, biological resin, leather or metal. Other materials need approval from the jury.

  • The rod holder must be universal to fit all types of fishing rods.

  • The rod holder must be rigid and durable.

  • The rod holder must be water and weather resistant.

  • The mounting system must not damage the canoe. It should fit all Trapper Canoes, the edge profile dimensions are shown in the above image.

  • Submit your entry with the native CAD format, STEP or IGES version, and include a rendering.

  • The winning design will be:
    - Universal
    - Environmentally friendly
    - Manufacturable
    - Easy to use
    - Match the Trapper Canoes brand

  • Project descriptions are strongly encouraged:
    - How you achieved a universal fit for rod holders
    - How your design mounts to canoes
    - Design dimensions
    - What eco-friendly materials you used
    - What design elements mirror the Trapper Canoes brand

    Never sure about the shipping on these kinds of items. But if you did win, (since they sell canoes anyway) perhaps Trapper could sell your canoe on your behalf and send you the difference minus a 5% sellers fee or something? I think that may be fair considering I live 5000+ Km away. ;)

    Hello,

    Here are some answers to your questions about the challenge.

    Leandro Fernande
    Yes, Trapper will cover the transport costs to the dealer closest to you.

    Shaman Jim
    Tahe Outdoors has a dealer in Australia where you could receive your prize.

    Robin D
    The inner surface of the Canoe is smooth as shown on the drawing of the edge profile.

    thinkin3d
    Eco-friendly solutions are favoured. It is satisfactory to use plastics and rubbers where absolutely needed.

    Doug Davey
    Unfortunately Taheoutdoors does not have a dealer in Africa.

    fjrivas
    The canoes are made for 1 - 3 people, depending on the canoe.

    michiel
    Eco-fiendly solutions are favoured but we might consider usage of some injection moulded parts.

    If you have any more questions then please leave them here.
    Keep up the good work! We allready have some very interesting designs.

    The winning designs are nice, but the rules have been changed a lot from the beginning of the competition and I am not a big fan of that. The main requirements were that the holder should be moveable in all directions, many of the chosen designs are static and can not be regulated in any way. You must have changed or deleted some of the beggining reuiqrements or you just simplified them. However I congratulate to the winning designs and wish the best. Regards.

    Luka B. over 10 years ago

    for example: RodHolder clamp V2 , also every design I made was fully qualified and is following every single requirement, but it would be unfair to point out someone, I am just trying to say, that this competition hasn't been well constructed. As did also Robert Sparks say, some of the winning designs just don't meet the requirements that were given at the beginning. Rules should't be changed so drastically from those on the beginning of this competition. I guess every single designer or engineer here could design a simple static holder without any movements, but the main requirements were, that you should be able to place the holder at any specific angle, at this was the hardest thing to do - to make a good looking design and also have the functionality that would meet the requirements.

    I don't want to argue nor do I want to take the prize away from someone else, I just think that there are several other designs that were constructed way closer to the first given idea. This is just my opinion,

    I wish you the best,

    Regards,

    Luka

  • Jonny Patty

    Jonny Patty over 10 years ago

    My joint favourites from finalists selected are ROD-REV by ivo.alberti & TRAPPER CANOE ROD HOLDER SYSTEM by andrea.garuti - these are good choices for 1st & 2nd. Great blend of design skill, novel ideas and in general both look like a product you'd want to buy. Well done to both.

    I really like nouamane's very clever concept, but it hasn't been developed into a low cost manufacturable product and may have a few problems (needs a catch to stop falling apart) and I feel the rod support is way to short... likely will mark the rod's cork/foam permanently due to bearing on edges & little distance between. Still it's a clever enough that it may still be deserving of a prize, however I think credit should be given where detail work / underlying issues (not to mention mastery of design for manufacture methods) have been addressed & completed.

    I don't feel the others shortlisted are not strong enough to be on there as finalists... in fact I'm very surprised.

    Another issue in general is material choice. I feel designers should have a holistic appreciation of materials they choose. Wood? Spec'ing just 'wood' or 'timber' is like spec'ing your fiance's engagement ring to be made from Carbon. e.g. To look at some extremes; Balsa or Teak, Spruce or Mahogany, Ash or Oak? Quite a spectrum in terms of; strength, hardness, durability in marine environment, dimensional stability in wet environment, ageing/drying required etc, BUT most importantly Sustainability - tropical hard woods are notorious for 'fiddled' sustainable management docs and anyone can see the deforestation issues that South America and Africa currently face (caused by Western demand) which suggest we should be avoiding tropical hardwoods where possible in order to be eco-friendly. So how are such designs rated for Eco credentials... when renderings suggest tropical hardwoods? At at the end of the product life, how will a knackered piece of wood be recycled? Into CO2 in the fire or into landfill?

    Also, take a close look at use of wood grain direction Vs geometry. Andrea's looks well considered for grain direction. Ivo's got 2 different grain directions rendered - may be a grain break out risk at the bridge part of the loop with either - nothing that couldn't be solved though (maybe 30, 45 or 60 degree grain direction to horiz?) Some other designs have more fundamental errors... grain rendered like it's moulded (like plywood) when design intent is from solid, and others have grain same direction as a tight rad on a structural leg, causing high stress concentration for no reason. Such engineering detail should be judged, otherwise it's more an art competition than an engineering competition.

    Will be interested to see retail price when winners hit market - many wood designs require skilled material selection & 3d machining with lots of setups - so very labour intensive! Andrea's maybe got the edge here - Andrea's product on a 2d CNC bed. That said, Ivo's is small, low piece part qty, little material used and really elegant. I can't separate 1st & 2nd :)

    I'll stand and voice my concerns with some of the finalists as well. Ignoring the adjustable angle requirement and then straight removing it from the description, without notice, is poor practice.

    "Did we leave anything amazing off the list?" - shameless plug, but I'll try.
    Look up "Rodholder Challenge Entry - Wood Composite v2". I can't seem to get the link to work in the comments.

    I'm surprised.
    Completely illogical choice.
    Wood will not work as clamp body. Wood will be damaged at such loads, all the more so, it is not possible to make a thread in wood.
    As for rodholders without clamp, it means, that canoe gunwale and rod holder should be make very accurately and be adjusted to each other. And should be take into account that gunwale has a curvature, and rodholder also should fit with this curvature and, that wood will change size when it wet. v

  • Andy Nicholson

    Andy Nicholson over 10 years ago

    I'm sorry but I have to agree with the majority of the comments on here. Most of the finalists designs don't meet the initial brief of being adjustable in all directions. That was 1 of the hardest parts of the challenge, otherwise it would have just been a styling challenge. In addition to this at least 1 of the finalists designs would probably damage the surface of the hull when tightened. Lastly the design which uses a jigsaw type assembly, although really good idea, is flawed by the requirement for a straight section of hull for it to all slot together, but the basic form of a canoe is curved from front to back and therefore this bracket style is limited to where it can be positioned.

    With regards to @Alexey firstly different woods would easily be strong enough for most of these designs, early (and some current) workshop clamps and tools are made of wood and would have no problem withstanding the forces involved here. Secondly you can very easily make a screw thread in wood, again vices and clamps can be made of wood and these products require screw threads. and finally you say wood will change shape when wet, yes this is true, but by finishing with a strong varnish etc, this will go a long way to prevent this.

    If I was pushed to pick a favourite, it would be ROD REV by iv.alberti purely on styling. It's not adjustable in any way but since it was uploaded it became my favourite for aesthetics and it's simple installation/use.

    I'm annoyed at how flawed this challenge has been from delaying the release of finalists, to picking designs which in the most part didn't meet the brief. hopefully other challenges will be better managed

  • Alexey

    Alexey over 10 years ago

    @Andy
    Yes I agree about workshop clamps, but look at their design and look at rodholder designs, they are different.
    Wood is anisotropic and this mean, that needs very carefully choose a wood blocks before manufacturing a such part like clamp. In worst case clamp will be damaged at using.
    Yes, make thread in wood it is really very easy. But how long this thread will life?
    Can you protect wood thread from water?
    There are some strong woods like oak or ebony but we speak about product for mass production which will be made on CNC. I think it is too expensive use a hard kinds of wood.
    About wetting. Ok maybe they really can be covered with suitable varnish. And holes in parts also will be protected.

    It sounds like everyone agrees that the winners should stick closer to the original adjustable at all angles requirement. I'll get this feedback to the jury and will ask them to look closer at whether the holder will harm the canoe.

    This is great feedback and is exactly what the finalist time is for, thanks! Now, it'd be great to see who you think should be included in the winner discussion who is not listed in the finalists. Who are we missing? It will help us ensure that the right entries are recognized.

    Poorly designed contest in my opinion. There's a lot of good overlooked designs. Pretty surprised at the results. Two of the finalists aren't adjustable and two look like they would damage the hull of the vessel.

    The following three designs really stood out to me and should definitely be considered in the final: (Included names and entry name incase links don't work)

    Trapper Canoe Rod Holder

    I like Canoe Rod Holder by Bj
    Canoe Rod Holder
    Very simple and interesting design. I would choose this rod holder for calm fishing with the light float fishing rod.
    For other conditions I would choose my design .

    I'll second that opinion for the Canoe Rodholder by BJ.
    It's a prime example of a design that followed the rules as originally stated. Easy to manufacture, low part counts, limited or no use of plastics, recyclable materials, fully adjustable.

    And while I'm at it, I'll plug my design again as well.

    Congrats to the winners. I'm sorry but I am bitter about the results. Firstly, the overall winning design is virtually the same as my own design, so why did I not even get a look in? I know designs in competitions are going to be similar but the winning design is virtually the same as mine from the way it attaches to the canoe to how the holder is adjustable. The only changes is, they've made it all from wood and added a little table and compartment add on. I'm not so annoyed that they've stolen my ideas, more annoyed that they on the whole thing and mine didn't even get mentioned, considering they are essentially the same design this doesn't make any sense

    Secondly the judging panel say that manufacture cost is a key factor, which is fair enough, but why choose the winner they have when that design has lots of small and larger parts to manufacture? just because it's made of wood surely doesn't make it that much easier to make

    Lastly, why bother having a criteria that the whole thing must be adjustable when the judging panel is going to just ignore that? they might as well have just said it would be nice to be adjustable, but not that important

    Sorry for being negative but this whole challenge has been a farce. Congratulations to those who won and enjoy your canoes

    Congradulations to the Winners!! But....I believe that the judges should really have read they're own rules..."Your design needs to include: the mounting system to the canoe, the rotating system for the rod holder and the rod holder itself." ...(2) of the designs picked did not adhere to these specifications. Great designs by everyone....but poor and misleading rules and judging.

    I am very glad that my work has been appreciated by the jury, giving me the chance to win my second challenge in GrabCAD.
    I'm not a fisherman. Thank you very much my friend Andrea Benati practicing competitive sports fishing since he was a child and gave me valuable advice to develop my idea in tune with the needs and mindset of a fisherman. Congratulations to the other winners!

    Sono anch'io sospreso del premio che ho ricevuto...
    Sono d'accordo con quanti hanno detto che il progetto di alcuni dei premiati non rispondeva alle regole richieste del challege ( tra i quali in mio ) per quanto riguarda la regolazione , tra le altre cose il pezzo che ho portato doveva essere un transitorio...mah
    probabilmente era destino , sono altresi d'accordo che la giuria ha lasciato fuori dei bei progetti , anche se ad onor del vero , bisogna dire che diversi sono impegnativi sotto l'aspetto dell'investimento dei componenti , pur essendo molto interessanti .
    Ducis in fundo , aldilà del ritardo , la giuria si è inventata un sesto premio ( e per me va bene ) ma che non era contemplato , probabilmente per non lasciarmi fuori , visto che risultavo tra i primi 5 ...:DDD , scusate il mio inglese , ma ho cercato di essere obbiettivo , complimenti agli altri vincitori ...

    I am also sospreso award that I received ...
    I agree with those who said that the project of some of the winners did not meet the requirements of the rules challege (including in my own) with regard to the regulation, among other things, the piece that I took was to be a transitional .. . mah
    probably it was fate, I also agree that the jury has left out some good projects, although to be fair, it must be said that several are challenging in the aspect of the investment component, while being very interesting.
    Ducis least, beyond the delay, the jury has invented a sixth prize (s fine by me) but that was not contemplated, probably not leave me out, because risultavo among the top 5 ...: DDD, sorry for the my english, but I tried to be objective, congratulations to the other winners ...

    Just reading this now and I’m really disappointed to learn that the criteria was changed half way through. This is really not good practice IMO and I can only hope
    It’s not a frequent occurrence. It’s cool to see the feedback from the community and how people are speaking out, I would have to agree with the overall sentiment that this challenge definitely has some issues, and that has nothing to do
    With my designs not being chosen. Of course I know I won’t be chosen every time no matter how amazing my submissions are, but when certain designs are chosen that don’t even meet the criteria proposed, you start to
    Really question if it’s worth it at all. Again, hopefully this challenge is a rare case.
    The main issues for me personally was that there was no mention of budget and only now we’re realizing that Trapper wanted the absolute bottom end budget wise, I think if we would have know this would have drastically changed most of our designs.
    Also, I have issues with the amount of “similar” or identical designs in this competition. I would like to know how a decision is made in cases where two designs are significantly similar. I won’t point out anyone in particular but there are a few examples in this competition. To me, in cases like this, I think date of posting should be heavily weighted in the decision making process and I think “first to post” should be considered as the winner even if second posters mods make for an overall better end product. The problem is that it’s not fair to put up a design and then have someone come along and just take a few days work to “improve” on it and then they get all the credit. I understand it’s nice to share etc. but this is a “COMPETITION”, it’s unfortunate but I’m seeing how private submissions might be a better route after all.
