Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Athletes in running-related sports face difficulties in maintaining the optimal 90-degree angle between their lower and upper arms during competition, which is crucial for proper form and performance.
Innovation Solution
A sports arm training device made of poly-elastic webbing with adjustable loops and Velcro releasable hook and loop fasteners is used to secure the arm at the wrist and bicep crease, maintaining the desired angle and providing slight tension to promote efficient arm motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If an athlete concentrates on maintaining proper arm position (90-degree angle), then arm form is improved, but attention to other aspects of sport performance deteriorates
Solution Approach 1:
The arm training apparatus automatically maintains proper arm position through elastic tension without requiring active concentration or control by the athlete. The device self-regulates arm alignment, freeing the athlete's mental focus for other performance aspects while the apparatus handles form correction passively.
Solution Approach 2:
The poly-elastic webbing acts as an intermediary mechanical element between the athlete's arm and the desired 90-degree position. It provides continuous passive feedback and physical guidance, mediating the relationship between natural arm movement and proper form requirements without requiring active intervention.
2Shape
If a rigid arm training device is used to enforce proper position, then arm alignment is improved, but comfort and ease of operation deteriorates
Solution Approach 1:
The device uses poly-elastic webbing that changes its mechanical properties dynamically - providing firm guidance when the arm deviates from proper position, but becoming compliant and comfortable when the arm is correctly positioned. This parameter change allows the same material to provide both correction and comfort.
Solution Approach 2:
Instead of rigid structures, the invention uses flexible poly-elastic webbing that conforms to the athlete's arm movements while maintaining alignment guidance. The flexibility allows natural movement within proper form parameters, eliminating discomfort associated with rigid enforcement.
3Adaptability or versatility
If adjustable loops and fasteners are added to accommodate different arm sizes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adjustable loops with Velcro fasteners create a dynamic fitting system that adapts to different arm circumferences. The adjustability allows the same device structure to accommodate various users without requiring multiple sized components, balancing versatility with structural simplicity.

AI summary
The present invention is related to sports training devices and, more particularly, to an arm training device for use in running related sports. The purpose of the invention is to hold the arm as close as possible at a 90 degree angle while running. The device comprises of a pair of poly-elastic webbing that is attached to both arms. The device is connected by a central segment. The central segment is attached to the lower wrist and upper bicep crease by buckles that the webbing is inserted through and then attached by Velcro releasable hook and loop fastening material to create a loop. The loop can be adjusted to fit most arm and wrist sizes. The poly-elastic webbing holds the arm at approximately a 90 degree angle while running. As result of the elasticity of the material, the arm will move forward and backwards faster while improving speed and technique.
