Swing Motion Training Equipment with Elastic Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment for strengthening swing motion ability in sports such as golf, tennis, and baseball is limited in improving balanced postures and muscular strength of both the upper and lower body, and causes discomfort due to pressure on the body during repeated swing motions.
Innovation Solution
The equipment includes a shoulder holder, a body holder, a pelvis holder, an extension, and an elasticity applier, with a Limited Stretch System (LSS) and magnet-metal attraction mechanism to provide comfortable and accurate joint movement correction, allowing for various swing motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nylon-reinforced bands are used for shoulder holder and body holder to prevent breaking, then reliability is improved, but comfort deteriorates due to pressing pain during repeated swing motions
Solution Approach 1:
The patent replaces rigid nylon-reinforced bands with flexible elastic bands that can deform and adapt to body contours during swing motions. The elastic bands are configured to provide resistance while allowing natural body movement, eliminating pressing pain while maintaining durability through the inherent elasticity and resilience of the material.
2Strength
If body holder is designed to be held on body during swing motion, then muscular strength improvement is achieved, but adaptability deteriorates because the holder keeps moving and requires frequent adjustment
Solution Approach 1:
The patent employs dynamic adjustment mechanisms including Velcro straps and elastic bands that allow the holder position to be easily adjusted during different swing phases. The elastic components provide continuous adaptation to body movement, maintaining optimal positioning without requiring frequent manual intervention, thereby supporting various swing motions including underswing, horizontal swing, and overswing.
3Strength
If equipment focuses on correcting upper body posture and increasing upper body muscular strength, then upper body strength is improved, but adaptability deteriorates in improving balanced postures and muscular strength of both upper and lower body
Solution Approach 1:
The patent designs a multi-component system with shoulder holder, body holder, and pelvis holder that can simultaneously address upper and lower body strengthening. The elastic bands connect multiple body points, enabling the equipment to provide resistance training for various muscle groups including shoulders, back, core, and hips, making it universally applicable to different swing motions and comprehensive fitness goals.
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
This solution effectively increases and improves both muscular strength and flexibility of the upper and lower body required for swing exercises, while ensuring comfort and allowing for accurate joint movement correction and various swing motions.
Implementation Method 1
a magnet and a metal are circumferentially installed with a predetermined distance therebetween on the first outer band, the magnet and the metal are attracted and attached to each other by magnetism when a pulling force is not applied in both circumferential directions of the first outer band, and the magnet and the metal are separated when a pulling force is applied in both circumferential directions of the first outer band
