Strap Length Governor for Portable Exercise Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bodyweight training devices are often bulky, inconvenient to transport, and limited in exercise range due to entangled straps and laborious adjustment mechanisms, restricting their use in home settings and requiring additional anchor points for full suspension exercises.
Innovation Solution
A compact, portable strap length governor device with a retractable mechanism and locking system, featuring a reel and spring bias to wind and adjust straps efficiently, reducing tangling and allowing easy setup, adjustment, and storage, while enabling modular exercise equipment configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bodyweight training devices use long straps for full suspension exercises, then exercise range is improved, but strap tangling and device bulkiness worsen
Solution Approach 1:
The strap is wound and stored within the housing cavity, nesting the strap material inside the device body. The reel rotates within the housing to wind the strap onto the spool, effectively hiding and compacting the strap length within the device's external dimensions, thus reducing device bulkiness while maintaining full strap length for exercise use
Solution Approach 2:
The reel is designed to rotate freely within the housing to dynamically adjust strap length during exercise. The locking mechanism provides dynamic control by transitioning between locked and unlocked states, allowing the strap to be secured at desired lengths or freely adjusted during movement, enabling full suspension exercises with adaptable strap configuration
2Adaptability or versatility
If conventional devices provide adjustable strap length, then exercise intensity variation is improved, but adjustment complexity and labor worsen
Solution Approach 1:
The return mechanism automatically winds the strap onto the reel when the locking mechanism is engaged, eliminating the need for manual knotting or complex adjustment procedures. The system self-regulates strap length by using spring force to reel in the strap, reducing adjustment complexity while maintaining exercise intensity variation through selective locking at different strap extensions
3Adaptability or versatility
If suspension trainers require high anchor points for full suspension exercises, then exercise range is improved, but installation requirements and accessibility worsen
Solution Approach 1:
The device transitions the anchor point requirement from a vertical dimension (high ceiling attachment) to a horizontal dimension (doorframe attachment at user height). By redirecting the strap through a doorframe anchor at accessible height and using the reel mechanism to manage strap length and angle, the system enables full suspension exercises without requiring high anchor points, improving accessibility while maintaining exercise range
