Apparel Body Position Feedback via Differential Foam Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Athletes often struggle to maintain proper body positioning and form during activities due to the inability to feel the position of various body parts, especially in areas with sparse neural populations like the lower back, leading to potential injuries and performance degradation when training alone without a coach or trainer.
Innovation Solution
Garment structures with integrated or attached body position feedback systems that apply differential compressive forces to stimulate nerves and deep tissue receptors, providing sensory feedback on body positioning through materials with varying moduli of elasticity, allowing athletes to develop muscle memory and improve form independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a coach or trainer is used to monitor and correct body positioning, then athletic performance and form are improved, but the athlete cannot train independently without constant supervision
Solution Approach 1:
The garment incorporates sensory feedback mechanisms through compressed foam materials that provide proprioceptive feedback to the wearer about body positioning. This allows the athlete to independently monitor and correct their form without external supervision, resolving the contradiction between needing accurate measurement and being able to train independently.
2Measurement precision
If the garment provides close fit to the body, then proprioceptive feedback is enhanced, but the garment may restrict body motion
Solution Approach 1:
The garment uses different foam densities in different body regions, with higher density foam in areas requiring precise position sensing (lower back, hips, thighs) and lower density foam in areas requiring greater freedom of motion. This local differentiation resolves the contradiction between enhanced sensing and motion freedom.
Solution Approach 2:
The foam materials are designed to be dynamic and adaptive, allowing the garment to provide varying levels of compression and feedback based on the athlete's movements and muscle engagement. The foam compresses and expands with body motion, maintaining sensing capability while accommodating natural movement ranges.
3Measurement precision
If higher compressive forces are applied to stimulate nerves and receptors, then body position awareness is improved, but the garment structure becomes more complex
Solution Approach 1:
The garment varies the density and compression characteristics of the foam materials to optimize sensory feedback. By changing the physical parameters of the foam (density, firmness, thickness) rather than adding complex mechanical or electronic components, the patent achieves enhanced sensory feedback while maintaining relatively simple garment construction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the wearer's awareness of body positioning, reducing the risk of injury and improving athletic performance by enabling better posture and movement habits, even when training alone, through targeted sensory feedback.
Implementation Method 1
which can help stimulate or interact with nerves, deep tissue receptors, joint mechanorecptors, etc. located in various portions of the human body, to better give the wearer sensory response in those areas and feedback as to the position of the selected parts of the body
Implementation Method 2
Materials having higher moduli of elasticity may be used in the body position feedback system to produce the higher compressive forces (and resist tensile stretching of the body position feedback system)

AI summary
An article of apparel includes: (a) a garment structure having one or more fabric elements structured and arranged to provide a close fit to at least one predetermined portion of a body and (b) a body position feedback system engaged with the garment structure, wherein the body position feedback system includes a material having a higher resistance to stretch than a resistance to stretch of the fabric element making up a largest proportion of the garment structure, wherein the body position feedback system does not substantially impede, alter or affect desired movement of the human body.
