Adjustable Strap Exercise Device for Muscle Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices often put excessive stress on forearm muscles, joints, and ligaments, particularly when gripping weights, and do not allow for free wrist motion, which can hinder effective muscle isolation during exercises.
Innovation Solution
A device comprising adjustable straps with loop shapes that allow for customizable fit around body appendages, reducing reliance on grip strength and distributing stress more evenly, thereby isolating the intended muscle group and alleviating stress on forearms and joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the user grips a weight to perform an exercise, then the exercise can be performed, but excessive stress is placed on forearm muscles, joints, and ligaments
Solution Approach 1:
The patent removes the gripping action from the exercise system by replacing hand-held weights with strap-based bodyweight resistance. The straps are looped around body parts such as the waist, thighs, or ankles to provide resistance without requiring forearm or grip strength, thereby extracting the harmful gripping component while preserving the exercise function.
Solution Approach 2:
The straps serve as an intermediary mechanism between the user's body and the resistance force. Instead of directly gripping weights, the user interacts with the straps that are positioned around various body parts, allowing force transmission to the target muscles without engaging the forearms or grip strength.
2Reliability
If the wrist is stabilized to prevent injury, then safety is improved, but free range of motion is restricted
Solution Approach 1:
The patent removes the wrist stabilization constraint entirely by eliminating traditional wrist straps and gripping mechanisms. Resistance is applied through straps positioned around the waist, thighs, or ankles, which do not interfere with wrist motion, thereby extracting the restrictive stabilization element while maintaining exercise safety through proper strap positioning.
3Stability of the object's composition
If the strap is tightly secured to the wrist, then stability is improved, but grip strength becomes the limiting factor
Solution Approach 1:
The patent removes the wrist-based strap attachment system and replaces it with bodyweight-based attachment points such as the waist, thighs, or ankles. This extraction eliminates the dependency on grip strength for strap security, as the straps are anchored to larger body parts that do not require gripping, thereby removing the limiting factor on exercise capacity.
