Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional punching-training devices have a fixed coefficient of elasticity, resulting in inflexible swing amplitude and frequency, limiting the effectiveness of hitting practice.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed elastic member is used in the punching-training device, then the structure is simple, but the swing amplitude and frequency cannot be adjusted, resulting in low flexibility for hitting practice
Solution Approach 1:
The patent applies the dynamics principle by making the elastic assembly adjustable rather than fixed. The first and second elastic members can be repositioned along the rod between a first position and a second position, allowing the coefficient of elasticity to be dynamically changed according to training requirements. This enables users to adjust swing amplitude and frequency by changing the relative positions of the elastic members, thereby resolving the contradiction between structural simplicity and training flexibility.
Solution Approach 2:
The patent implements parameter changes by allowing the coefficient of elasticity to be adjusted through repositioning the elastic members. By changing the physical position of the first and second elastic members along the rod, the effective stiffness of the elastic assembly is modified, which directly changes the swing characteristics (amplitude and frequency). This parameter adjustment capability enables the device to adapt to various hitting practice scenarios without requiring complete structural redesign.
2Ease of operation
If the elastic member is made adjustable to improve swing amplitude and frequency control, then the flexibility of hitting practice is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the elastic assembly into distinct first and second elastic members that can be independently positioned. This segmentation allows each elastic member to be adjusted separately along the rod, providing fine-grained control over the swing parameters. The modular nature of having separate elastic members that can be repositioned simplifies the adjustment mechanism compared to a completely redesignable elastic system, thus improving ease of operation while controlling device complexity.
