Solution Overview
Problem
Existing leg exercise equipment is either large and bulky, requires electrical power, or is not portable due to its design, leading to inactivity and associated health issues like leg/foot fatigue and blood clotting from prolonged sitting.
Innovation Solution
A portable, non-motorized exercise apparatus with parallel tracks and limb receiving members that can be folded for storage, featuring elastic bands providing resistance for manual sliding movement, allowing users to exercise legs or arms without a power source, suitable for use in various positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If exercise equipment is designed to be portable and foldable, then ease of transport and storage is improved, but structural complexity increases
Solution Approach 1:
The exercise device is divided into separate modular components including parallel tracks, limb receiving members, and elastic bands that can be independently assembled and disassembled. This segmentation enables easy folding and storage while maintaining structural integrity during use.
Solution Approach 2:
The device incorporates movable and adjustable components such as foldable tracks and reconfigurable limb receiving members that transition between static operational positions and dynamic folded storage positions, enabling portability without permanent structural complexity.
2Ease of manufacture
If exercise equipment is made non-motorized, then ease of manufacture and portability are improved, but exercise intensity and effectiveness may be reduced
Solution Approach 1:
The device converts the potential disadvantage of non-motorized operation into a benefit by using elastic bands to provide progressive resistance that increases with user effort. The elastic resistance mechanism transforms simple manual movement into effective strength training without requiring motors or power sources.
Solution Approach 2:
The exercise intensity is adjusted by changing the tension parameters of elastic bands rather than relying on motor power. Users can modify resistance levels by selecting different elastic bands or adjusting their tension, providing variable intensity exercise through passive mechanical means.
3Ease of operation
If exercise equipment is designed for seated operation, then ease of operation is improved, but health risks from prolonged sitting increase
Solution Approach 1:
The device enables periodic leg movement through reciprocating motion along the tracks, creating regular cycles of muscle contraction and relaxation. This periodic action promotes blood flow and prevents the harmful effects of prolonged static sitting while maintaining operational simplicity.

AI summary
An exercise apparatus for use in for example a leg exercise comprises a pair of tracks extending in a respective longitudinal direction, each carrying in sliding movement therealong a limb receiving member for supporting a limb of the user. The tracks are interconnected by a bridging portion comprising a hinge which defines a central folding axis parallel to the respective longitudinal direction of each track, so that the tracks can be moved between an operating position in which the folding axis is located transversely between the tracks and a storage position in which the tracks are disposed so that upper load bearing surfaces are oriented so as to face one another. The apparatus also includes a resiliently deformable elastic band defining a limit in the range of sliding movement of each limb receiving member along the track so as to apply gradual resistance to the limb receiving member upon contact with same.
