Exciting engineering challenges with great prizes

Show off your skills and solve real design problems

BOAST YOUR TOAST! Reinvent the toaster

Medium

Sustainable Minds and IDSA invite you to reimagine the toaster to differentiate and position an existing kitchen appliance manufacturer, or a new company that you imagine, as a leader in high-performance home appliances with environmental performance’ as a key component of the story.

To do this, we’re providing you with a proven process and tools to generate innovative design concepts and measure
the environmental performance of each to identify the best solutions. By participating in this challenge, you’ll learn
how to consistently integrate life cycle thinking and environmental performance improvement into your (and your company’s) design processes.

We are looking for you to:
1. Tell a great brand experience story.
2. Defined user persona(s) and scenario(s), key insights that inform the strategy
3. Demonstrate how using multiple ecodesign strategies in multiple product life cycle stages creates innovation ideas
(even if most apparent innovation is not your final selected solution). Material changes only are generally not
innovations.
4. Show a 15% environmental performance improvement over the reference toaster.

    I already have 3 patents on convection toasting.. I send high temp air through the bread first from one direction then the fans reverse so the heated air can travel and toast the 2nd side .. the forced heated air makes toast in approx. 5 seconds ...this uses approx 35% less energy .. The devise also takes up 30 percent less space and uses 25% fewer materials to manufacture. I'm experimenting with liquid flavor additives that I spray mist into the ducting . This infuses flavor like cinnamon and even butter without the soggy issues. I don't have time to follow the format however I'd like to talk. Thank you.

    After creating a login on SM website, go to Eco-concept Modeling & Life Cycle Assessment Software
    Download the quick start guide and download the example toaster project. Now set up a new project.
    Now create a reference concept using the downloaded toaster sBOM, which will give you complete details about the product materials. Complete the reference concepts by filling in use stage, end of life stage and transportation basis the details provided in the downloaded SM_Example_Project_Instructions.pdf

    The toaster model on SM software is NOT a 3D model, it is details about the reference product, highlighting the energy intensive areas being consumed at various stages of product life cycle
    You will have to create a new design in 3D which should be better than the reference in terms of environmental performance
    Hope this helps

    Hi @jacob carter, thanks for the feedback on my toaster design! But I actually put down the power rating at 1.8kWH not 2.4kWH for that toaster design (or maybe lower), but it was infact the other concepts that had 2.4.

    @Jacob Carter. I believe I made a typo. I meant to say 1.4 kWH (or something lower) instead of 2.4kWH (whilst still making the final concept use less energy than the others). Sorry I'm dyslexic and make these kind of mistakes all the time. Please take this into consideration competition people! :) @Shruti Parikh @Stephan Clambaneva

    Ah, well that happens. At least it was caught early ! I believe you have made an error, for the reference toaster, to find out the energy consumption you were meant to input the values provided in the example pdf. As to the number 2.4 kWh, a more realistic number 0.24 kWh. However, this is not a typo on your behalf, the source which you have stated as the reason for 2.4 kWh value made a calculation mistake !

    Congratulations to everyone ! I have a few things I will love to share !

    1) Toaster Slide Design: Re-invent the toaster I liked the level of detail in this CAD model, clearly a lot of work put in. However, the concept is not entirely new as I have seen this concept before. The increase in sustainability is fairly low, which could be enhanced. UPDATE: The consumption for energy was a mistake from Jamie Saunders and does not reflect the actual consumption. Toaster Slide Design: Re-invent the toaster

    2) Eco-Crisp Toaster I found this interesting with the circular economy. One possible issue with the flap, is the build up of a lot of heat, and especially VOCs which can be quite dangerous especially when the consumer opens the flap, a nice whiff of VOCs and dry heat ! Eco-Crisp Toaster

    3) Svasth I liked the concept, there are many designs which have incorporated multiple features, so the concept is not novel. With the egg frying and toasting, one issue is the time difference. The toaster in that diagram can only provide a certain amount of heat for the egg, around low-heat settings. As a results the egg will take quite long and there is a risk of under cooking the egg easily and also it sticking to the top region. Additionally, in terms of user desirability, I feel it is somewhat lacking as I would be forced to clean the top over and over again, as the toaster will always be positioned like that. Also I feel this is an easy fire hazards there is no clear indentifable way to determine which side is for heating. By the time you do realise, you will have a burn mark on your table and a lot of explaining to do :) Svasth

    4) Vitae Toaster Not an entirely bad design, I feel a lot of the appeal of the visuals which I like. The business strategy of the circular economy is quite interesting, but there is not a lot of innovation otherwise in my opinion. Vitae Toaster

    5) Ember Stovetop Toaster The idea of removing mindless interactions is interesting, but I do not feel this would be adopted by the market widely, as previous stovetop toasters in the modern era have failed for appeal. Additionally, in one of my previous projects, where I pitched products such as these (very similar concepts) many users state they like the environmental aspect and the inspiration, but many would fail to adopt the design, due to inefficiency. A key issues I feel (which has really missed out the entire idea) is the inefficiency of the design due to inconsistent toasting, driving away many from buying the design. After all I prefer nice toast more over helping the environment. Also using induction hobs are not that energy efficient - even if you place it whilst it is cooling down the toast will not heat up properly. This is a huge flaw and can lead to increase environmental impacts ! Ember Stovetop Toaster

    6)TOASTER_BY_TRISTAN_CANNAN One thing I love is the concept process and some of the market research but otherwise I find the design quite bland and not entirely innovative Whilst the author talks about reducing clunkiness, I feel this design does not really improve on that at first glance and would easily put me off ! TOASTER_BY_TRISTAN_CANNAN

    7)Contemporary Glass Toaster I am afraid to say this design has been done multiple times ! Near indentical versions have been produced and the lack of appeal is actually the lack of necessity ! Many users do not need to see their toast being toasted to the right level. Why? Once they find the perfect level of toast, its simply an everyday process from then. The materials may be more sustainable but there will be an increased need for care of the device due to less durability and this impacts earlier stages in the LCA process. Contemporary Glass Toaster

    8)FIERFLY air toaster Innovative ? Definitely ! Would I buy it personally, no ! The main reason is the increased noise of the device ( I already have morning headaches do not need another one!) and also the decreased efficiency.FIERFLY air toaster

    9)Toaster design Nice design but One possible issue is the build up of a lot of heat, and especially VOCs which can be quite dangerous especially when the consumer opens the flap, a nice whiff of VOCs and dry heat ! The design is hi-tech but many components are not necessary and the drive to create a hi-tech solution nowadays is getting out of hand. Many features are unecessary and are not based of real user-data and can increase the environmental degradation ! Toaster design

    10) Ding Toaster Quite a clunky design with many uncessary substructures. I like the visuals but perhaps the environmental performance could be enhanced (particularly by removing the excess unnecessary features)

    I can see on other challenges community input is taken into account, and I feel a few models should be noted and considered for winners. My favourites pick (in no particular order):

    1) Vitae Toaster Vitae Toaster
    2) Svasth Svasth
    3) EcoToaster EcoToaster
    4)Viridis Nova: The user-friendly and green toaster of the future

    No 4. I feel this design is incredibly innovative and functional , and whilst some of the visuals is not as flashy as the others, the design seems to solve multiple problems for me all at once, surprised it was not chosen as a finalists. The design is both feasible and has informed design choices. The design incorporates a user-centred design and more sustainability whilst improving efficiency of the actual toast ! The attention to detail was great with some of the features, and the performance improvement was also high ! I would purchase the design (provided the price is not too high). Viridis Nova: The user-friendly and green toaster of the future Viridis Nova: The user-friendly and green toaster of the future

    No 3. has nice visuals and appeared to have a nice function (could not fully tell as they did not submit the powerpoint) and I feel if they submitted some documentation they would be a contender. Viridis EcoToaster

    Congratulations everyone!
    Loved your feedback @Jacob Carter
    I was thinking the tapered body towards the top gives it a direction and the edge illumination will help the user know when the hot plate is turned on, which would be helpful in reducing incidents like fire hazards.
    Cleaning the toaster surely is an issue but I was not sure what an ideal solution would've been. Now when i think of it i feel a simple removable cook plate would've had solved the cleaning problem.
    I'll surely try and put together things you pointed to make the toaster better. Thank you.

    @Annuai the taper would help, but normally in many regions, with pans such as these, often they heating regions have more surface are than the rest of the body, and I think it is important to consider this ! A removable plate would be ideal, but will require more material to be used

    @ Jamie Saunders Power rating is measure in watts, energy consumption is measured in kWH . I think there is some confusion between the two.

    @shih-hsuan, huang
    With regards to the controller part, I feel the mechanism is fairly unnecessary as there are many different methods that can be used as an alternative with less mass and materials used. Also with the orientation of the toaster, is there a particular reason why the device is sideways as opposed to upright. For many lifting the toast from an upright position is much more ergonomic and also helps VOCs to escape easily, otherwise there will be high concentrations being built up in the toaster especially at the top.

    Additionally, I feel there is a flaw with having the toast easily taken out . If you look at normal toasters, they wrap around the bread, allowing for faster heating up. If the bread in this case is too thin, for example the toasting will be quite inefficient.

    Also if you do not mind me asking, what rendering software did you use to product the visuals

    Hi @Jacob Carter, thanks for your feedback.

    I guess the controller part you motioned is our separated timer switch, if not please let me know. You could find the video of our toaster with the link below.

    In our design process, in order to prevent user touching the hot toaster, applying symmetric parts design to decrease manufacturing cost, and simplifying the input operation scenario, we decided to separate the switch with the main body. The result is that we shrink the toaster size about 50%, which means our toaster is only half size of traditional toaster which not only safe the materials and the size of user's kitchen, and because of the small toaster cavity, we are able to decrease our numbers of heating plate.

    About the orientation of the toaster, we did make some design modifications to make our side opening toaster possible.
    1. hot air goes up, so traditional toaster waste some energy to cover the escaping hot air. As we turned the opening to side, it will decrease the leasing of hot air.
    2. hear transfer faster in solid metal than in the air, so we create single sheet metal shades around each tunnel, so that the cavity is heating up more equally even we only use one heating plate in our toaster.
    3. We use the frame to bake the toast so that the way to operate our toaster is also ergonomic.

    About the toaster frame design, we had already found there's existed design from SMEG as the link below,
    https://www.connox.com/categories/accessories/spare-parts-replacement-parts/smeg-sandwich-pliers-for-tsf01-tsf03-toaster.html
    Their design is good enough so that we can use directly, which was designed a little bit narrow than toast that the frame can hold the toast tightly. but considering it's not our original idea, we just use a simple frame in our current design.

    We used Keyshot for the photo rendering.

    I hope we answered your questions, and welcome for more discussions.
