Solution Overview
Problem
Conventional running vests do not effectively maintain proper arm alignment during running, leading to inefficient arm movement and potential injury from improper swing mechanics.
Innovation Solution
A running harness with adjustable straps and training devices that include a base, strap fastener, band with elasticity, and a lock system to maintain a predetermined arm swing parameter, allowing for customizable fit and alignment to optimize arm movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional running vests with simple straps are used, then the device complexity is low, but the arm alignment and movement control are insufficient
Solution Approach 1:
The strap system is divided into multiple independent components: a main strap, an arm loop, and a lock mechanism. This segmentation allows each component to perform a specific function - the main strap provides overall support, the arm loop controls arm movement, and the lock mechanism maintains position - thereby achieving reliable arm alignment without requiring a completely complex integrated structure.
Solution Approach 2:
The strap system incorporates dynamic elements including an adjustable lock mechanism that can be positioned at different locations along the strap, and an elastic band that adapts to the runner's arm movement. This dynamic capability allows the system to maintain proper arm alignment while accommodating individual anatomical differences and movement patterns, resolving the contradiction between reliability and complexity.
2Adaptability or versatility
If fixed strap configurations are used, then the device complexity is low, but the adaptability to different user anatomies is poor
Solution Approach 1:
The lock mechanism can be positioned at multiple locations along the strap, allowing the arm loop to be adjusted to different heights and positions. This dynamic repositioning capability enables the same strap system to accommodate runners with different arm lengths, torso lengths, and anatomical proportions, providing high adaptability without requiring multiple completely different strap designs.
Solution Approach 2:
The system allows change in key parameters such as the position of the arm loop along the strap length, the tightness of the lock mechanism, and the configuration of the elastic band. By enabling users to adjust these parameters, the system can be customized to match individual anatomical dimensions while using a single standardized strap design, thereby achieving adaptability without proportional increases in complexity.
3Reliability
If no arm alignment control is provided, then the device complexity is low, but the risk of injury from improper swing mechanics increases
Solution Approach 1:
The arm alignment function is isolated into a separate arm loop component that is coupled to the main strap through a lock mechanism. This segmentation allows the alignment system to be designed as a simple, dedicated component rather than an integrated complex system, focusing specifically on controlling arm swing mechanics while leaving the rest of the strap system relatively simple.
Solution Approach 2:
The lock mechanism acts as an intermediary element between the main strap and the arm loop, providing a simple yet effective means of controlling arm alignment. This intermediary component translates the overall strap support into specific arm position control, preventing improper swing mechanics and reducing injury risk without requiring complex active control systems.
