Resilient Strap Training Device for Flexible Core Strengthening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leg training devices are cumbersome, limit flexibility, and cause discomfort due to restrictive designs and improper foot engagement, failing to effectively strengthen the core and legs during normal exercise routines.
Innovation Solution
A training device featuring a waist belt with adjustable Velcro ends, multiple attachment loops, and resilient straps connecting to foot engaging platforms, allowing for secure and versatile attachment and resistance during exercises, with adjustable straps to accommodate different user sizes and exercise positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full upper body harness with fixed cables is used, then the structure provides stable support, but the user's movement flexibility is substantially confined
Solution Approach 1:
The patent replaces fixed cables with resilient cables that can dynamically adjust their length and tension based on user movement. The resilient nature allows the cables to extend and retract, providing structural support while accommodating a wide range of motions without confining the user's flexibility.
Solution Approach 2:
The invention changes the physical parameter of cable rigidity by using resilient cables instead of rigid fixed cables. This parameter change allows the system to maintain structural stability while adapting to different movement positions, resolving the contradiction between stability and flexibility.
2Device complexity
If separate straps with fixed cable lengths are used for front and back, then the structure is simple, but the versatility for different exercise positions is substantially limited
Solution Approach 1:
The patent creates a universal training device where the resilient cables and adjustable attachment points allow the same basic structure to be used for multiple exercise positions and configurations. The system can adapt to front, back, side, and diagonal exercises without requiring separate fixed-length cable assemblies.
Solution Approach 2:
By making the cables resilient rather than fixed-length, the system gains dynamic adaptability. The cables can adjust their effective length through elastic deformation, allowing the same simple structure to accommodate various exercise positions and ranges of motion.
3Reliability
If foot engaging loops are secured at the arch of the foot, then positioning is stable for stationary users, but great discomfort results from pressure on the arch
Solution Approach 1:
The patent distributes the attachment points across multiple locations on the foot (toes, heel, midfoot) rather than concentrating pressure at the arch. This local quality change allows the system to maintain secure foot engagement while eliminating the harmful pressure concentration that causes discomfort.
4Device complexity
If a single strap passes along the inner surface of the belt, then attachment is simple, but undesirable pressure is applied to the body during movement
Solution Approach 1:
The patent divides the single strap into multiple separate resilient straps that can be independently positioned and attached. This segmentation allows the straps to distribute pressure across different body areas and reduces the harmful concentration of force on any single point, while still maintaining simple attachment through the resilient connection system.
