Inelastic Strap Exercise Apparatus with Adjustable Yoke
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resistance exercise devices, including elastic and inelastic strap-based systems, are limited in versatility, consistency, and user adaptability due to fixed resistance characteristics, limited exercise range, and inability to support varying user weights, restricting the diversity of exercises and user compatibility.
Innovation Solution
An adjustable inelastic exercise apparatus featuring a substantially inelastic strap with a rigid yoke and anchor system that allows for adjustable length, selective fixation, and customizable resistance through a pin engagement mechanism, enabling a wide range of exercises by accommodating different user stances and weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If elastic bands are used to provide resistance, then the device can be made compact and portable, but the resistance is inconsistent and increases with displacement, limiting exercise diversity and user compatibility
Solution Approach 1:
The patent applies dynamics by making the resistance mechanism adjustable rather than fixed. The inelastic strap system allows users to dynamically change resistance levels by adjusting strap length and positioning, enabling the same compact device to adapt to different exercises, user strengths, and resistance requirements, thereby resolving the contradiction between compact size and exercise diversity
Solution Approach 2:
The patent changes the resistance parameter from being inherently variable (elastic bands that increase resistance with displacement) to being user-adjustable (inelastic straps with fixed resistance). By allowing users to change strap length and configuration, the system provides consistent resistance that can be tailored to different exercises and user capabilities, maintaining compact size while expanding exercise diversity
2Ease of operation
If elastic bands are used, then the device remains portable, but different users cannot use the same device for the same exercise due to differences in height, weight, or strength
Solution Approach 1:
The system enables dynamic adjustment of strap length and positioning to accommodate different user heights, weights, and strengths. Each user can customize the resistance configuration to match their specific exercise requirements while maintaining the same portable device, thereby achieving both portability and universal user compatibility
Solution Approach 2:
The patent creates a universal exercise device that can serve multiple users with different physical characteristics through the adjustable inelastic strap system. The same compact device can be configured for various exercises and user types, making it universally applicable while remaining portable
3Device complexity
If fixed length inelastic straps are used, then the device structure is simple, but the range of exercises is limited
Solution Approach 1:
The patent introduces dynamic adjustability to the inelastic strap system, allowing users to change strap length and positioning based on exercise requirements. This maintains relatively simple device structure while significantly expanding the range of possible exercises through user-configurable settings

AI summary
An inelastic exercise apparatus includes an elongated member having a pair of ends. The elongated member is an inelastic strap. The apparatus also includes an anchor having a first portion for mounting to a structure and a second coupling portion. The exercise apparatus further includes a rigid yoke including a yoke housing having a first end and a second end, wherein the first end of the yoke housing is coupled to the second coupling portion of the anchor and the second end of the yoke housing defines a translation channel configured to receive the elongated member.
