Portable Leg Exercise Device
Current Problem
Brian, a certified sports trainer often used the traditional leg exercise machines both personally and during personal training to help his clients increase leg strength, improve acceleration and also engage the upper torso for overall conditioning. Unfortunately all existing leg exercise devices were heavy, large and difficult to transport and store. Brian decided to develop a solution.
Developing A Solution
Brian then approached his good friend Greg, a professional electrical engineer who he has been friends since grade school. Brian and Greg had a number of discussions and then Greg generated a conceptual design and built an initial proof of concept prototype.
Prototype Design
Believing they needed a better quality prototype to better demonstrate and explain their product to investors, they hired DCP to design their next prototype. The primary design goals for their prototype were for it to be very strong and sturdy while also being portable, lightweight and easy to assemble and disassemble without any tools for transport and storage!
Meeting all of these design goals was quite challenging, however after 9 design iterations and refinements Brian and Greg approved the prototype design for their product. Once approved DCP provided them with an accurate estimate to build their next prototype.
Physical Prototype Project
Very pleased with the completed design service as well as the prototype cost estimate, Brian and Greg moved forward with DCP to develop their prototype. Due to the size and complexity of the product, it took many months to complete the prototype. However, the clients were were very pleased with the prototype once it was completed and shipped to them!
Once they received their prototype, Brian and Greg started working on strategies to introduce their Leg Exerciser prototype to the industry and marketplace with the goal of attracting outside investment and strategic partnerships to manufacture their product.
Testimonial
“Dirt Cheap Prototypes has been very professional and have met our expectations with regard to the design services we hired them for. Our discussions have also been very helpful with the development of our long term strategic plan for the commercialization of our product.
We plan on continuing to work with the DCP team for our prototyping and very possibly beyond.”
