Portable Exercise Frame Modular Design Wheelchair Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise frames are not portable enough for therapists and trainers to easily transport to multiple client locations, nor do they accommodate users in wheelchairs, and they lack features for easy assembly and disassembly.
Innovation Solution
A portable exercise frame with a modular design that can be quickly assembled and disassembled using removable pins, featuring a floor plate for wheelchair accessibility, telescopic exercise bars, and anchoring members that double as hand grips for easy handling and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If exercise frame is made portable with modular components, then ease of transport and assembly is improved, but structural stability and strength may deteriorate
Solution Approach 1:
The exercise frame is divided into modular components including a base frame, vertical posts, overhead bar, and resistance elements that can be independently assembled and disassembled. Connection points with quick-release mechanisms allow rapid assembly without compromising structural integrity during use.
Solution Approach 2:
The frame incorporates adjustable components such as telescopic vertical posts and repositionable overhead bars that can be dynamically configured to different heights and positions. This dynamic adjustability maintains structural strength while enabling easy adaptation to different user needs and portable assembly.
2Ease of operation
If exercise frame is designed for high portability, then ease of transport is improved, but device complexity increases
Solution Approach 1:
The base frame serves multiple functions as both the foundation for structural stability and the primary carrying structure with integrated handles. The vertical posts provide both structural support and serve as attachment points for resistance elements. This multi-functionality reduces the number of separate components needed, simplifying the overall system despite portability requirements.
3Adaptability or versatility
If exercise frame accommodates wheelchair users, then user accessibility is improved, but device complexity increases
Solution Approach 1:
The wheelchair accessibility features are merged into the existing frame structure rather than added as separate components. The base frame is designed with sufficient width and stability to support wheelchair users, and the overhead bar system can be adjusted to accommodate various user positions including seated wheelchair users. This integration avoids increasing device complexity.

AI summary
A floor plate is suitably sized to receive a wheelchair and also supports a base frame along rear and side edges. Prepositioned brackets on the floor plate secure the base frame using quick-connect fasteners. Opposite side portions of the base frame carry elevated, horizontal, tubular, side housings that telescope over elongated exercise bars. A fastener secures each exercise bar in a housing at a variably selected degree of insertion. An upright tube at the rear of the base frame has an open top forming a socket. An upright standard engages the socket and carries an overhead bar supporting a transverse crossbar over the center of the floor plate. The ends of the crossbar, the front ends of exercise bars, the front end of the floor plate, and various other locations on the base frame carry C-shaped attachments for clip-on resistance members. The attachments are sized to serve as handgrips. Casters on the rear edge of the floor plate are moved into ground-engaged positions with the upward tilting of the front of the floor plate, which is aided by the use of handgrip attachments on the front of the floor plate. Fasteners securing the base frame to all other components are quickly released for rapid disassembly of the exercise frame, enabling it to be transported by hand or by vehicle to a next site.
