Was on vacation last week so I missed your comment.
Looks like our views are not that far apart on this. In any group the their are unrealistic zealots that do their pet cause more harm than good. Mr. Dart's comments clearly indicate that he is not one of the "problem children".
Thanks for weighing in, James. It's good to hear from the inventor about his work directly. This is the best way to foster a live discussion about this type of work and research and ultimately achieve the goals of what you're trying to do. Good luck with your future and keep us informed of other projects.
These are good points, Dennis, thanks for bringing them up. I can see both sides of this issue and think experimentation with sustainable and eco-friendly materials, even if the finished product doesn't meet design standards already set for products, is a good thing. But I also see how it would probably do more for the mission of eco-friendly materials if the products invented were viable for commercial use in the end.
Hello all, thank you for your comments. I agree strongly that this is not yet a viable product. The aim of my investigation was to take a fascinating new material, try to understand it and really demonstrate that with the power of making, it can be put to good use. The Dragonkraft material is the star here
My course was a Bachelors in 3D Design, there was a large emphasis on Craft and making. Unfortunately this was not a sole preoccupation, and as has been correctly suggested, full and proper testing is where this project reaches it's limitations.
I feel that what I have achieved over a few short months was to help to move a material forward in a new direction. In doing so, I have the seeds of a concept that is not unfeasible. In fact, while attending the JEC International Composites show in Paris this year, it was the material possibilities that captured some imagination and interest.
Furthermore, I have gathered interest from a leading European helmet manufacturer. I will be continuing the process of research and development from here in Switzerland. It is thanks to people like you who do take notice and help to push this along [and further away from a simple, or unproven, design showpiece]. It is very important that people continue to cut through the eco BS and say 'yes this has a future' or 'this lacks in some capacity'
Please do leave more of your thoughts and feedback. Thank you
It's also helpful to keep in mind that these university projects are often proof of concept experiments/student learning experiences. I did wonder why a food-related crop was being used, and also why a totally new resin was being investigated, when there are so many already out there, already commercialized in volume. Not every innovative material or process we report on that starts in a lab ends up being used in actual products.
Sometimes I feel that the folks working on sustainable or eco-friendly ideas shoot themselves in the foot at the start by forgetting the end product objective.
Sure, we all wish that everyone shared our concerns and priorities and will flock to our product because of that. That can work with a small volume niche product.
However, if the eco-friendly designer really wants to make an impact (rather than just a "statement") in the areas they feel are important they will need to make a product that delivers excellence in the metrics that are important to the consumer while acheiving their personal enviromental goals. Is that a high bar? Sure, innovation always is. When somebody whines that we "should" be doing something their way for whatever personal reasons they find "morally compelling" it seems to be a signal flag saying "my product can't cut it on it's merits". My opinion anyway. Rant mode off. ;^D
That's really good to know, Ann. I'll check out your article. So the strength isn't the issue here. It seems like, at least in this first iteration, that the issue is the weight of the helmet. So I guess the trick is to find a way to make it strong without a lot of weight. I'm sure it can be done.
Bioplastics are getting stronger all the time, and some are even used in under-hood vehicle applications as we've reported: http://www.designnews.com/author.asp?section_id=1392&doc_id=243857 But few of them are strong enough to sustain really high impacts, such as for sports equipment like balls or golf club. Golf clubs are one application where carbon fiber, which is an extremely strong material, got its start. Helmets, of course, also have to be impact proof. But there are other types of sports-related equipment that don't have to sustain such high impacts, like shoes: http://www.designnews.com/author.asp?section_id=1392&doc_id=239645&image_number=2
Linear guides are one of the most important components required for the development of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides in machine design, can enable designed-in functional features.
