The prompt
I am seeking an experienced CAD designer and/or mechanical engineer to develop a professional 3D CAD model for a patent-pending medical mobility device called StrideAssist 2.0. StrideAssist 2.0 is an advanced mobility assistance device that combines adjustable shock absorption, energy return, ergonomic support, and modular functionality. The device is intended to reduce impact stress on the user while improving stability, comfort, and mobility. The winning designer will: Create a complete 3D CAD assembly Develop individual part models Design a functional adjustable shock absorption system Create an exploded assembly view Produce engineering drawings suitable for prototyping Deliver STEP files and native CAD files I will provide: Patent drawings Concept sketches Written descriptions Feature requirements Important features include: Adjustable spring and damping system Lightweight structural frame Ergonomic grip and support components Adjustable height mechanism Modular architecture for future expansion Experience with medical devices, mobility aids, prosthetics, orthotics, or mechanical product development is highly preferred. All intellectual property and design rights will transfer to the contest owner upon selection of the winning design. Wants: Designs will be evaluated based on: Mechanical feasibility Manufacturability Professional CAD quality Innovation and problem-solving ability Attention to detail Understanding of mobility and medical device design Ability to incorporate adjustable shock absorption features Quality of assembly organization and engineering documentation Preference will be given to designers with prior experience in: Medical devices Prosthetics Orthotics Rehabilitation equipment Mechanical product design Don't Wants: Simple artistic renderings without engineering consideration AI-generated concept art without CAD capability Designs that ignore the provided patent drawings Non-functional mechanisms Excessively complex parts that would be difficult to manufacture Stock or copied designs Low-detail submissions without assembly planning
