Elastic String Training Device with Multi-Strand Knots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current martial arts training devices are costly, tedious, and ineffective in improving coordination and quick reflexes, as they lack dynamic and cost-effective solutions for practicing movements without risking damage.
Innovation Solution
A training and coordination device comprising a projectile member, such as a sack or ball, attached to an elastic string with a multi-strand portion and knots, allowing for random motion when struck, enabling users to practice martial arts skills in a dynamic and cost-effective manner without the need for constant retrieval or risk of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional martial arts training devices are used, then training effectiveness is improved, but cost and portability deteriorate
Solution Approach 1:
The training device is divided into separate components: a projectile member (sack or ball) and an elastic string. This segmentation allows the device to be manufactured from simple, inexpensive materials while maintaining training effectiveness. The projectile can be filled with inexpensive materials like rice or beans, and the elastic string is a common, low-cost item.
Solution Approach 2:
The patent employs inexpensive materials that can be easily replaced if needed. The projectile member can be made from simple sacks or balls filled with cheap materials, and the elastic string is a disposable component that can be replaced. This approach dramatically reduces manufacturing cost while preserving the core training function.
2Reliability
If traditional martial arts training devices are used, then training effectiveness is improved, but portability and convenience deteriorate
Solution Approach 1:
By separating the projectile member from the elastic string, the device becomes highly portable. Users can carry just the small projectile in their hand or pocket, while the elastic string remains attached to a fixed structure. This eliminates the need to transport large, cumbersome training equipment.
Solution Approach 2:
The fixed structure (wall, tree, ceiling) serves as the anchor point, extracting the need to carry the entire training system. Only the essential projectile member needs to be portable, while the elastic string and anchoring system remain stationary, greatly improving convenience.
3Device complexity
If static training devices are used, then simplicity is maintained, but coordination and reflex training effectiveness deteriorates
Solution Approach 1:
The elastic string introduces dynamic behavior to the system. When the projectile is struck or released, it moves unpredictably due to the elastic recoil and tension in the string. This dynamic motion requires users to develop quick reflexes and coordination, while the device itself remains mechanically simple with no complex mechanisms.
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
The device enhances martial arts training by providing a cost-effective, portable, and dynamic means to improve coordination and reflexes through random motion, mimicking realistic training scenarios while minimizing risk of injury.
Implementation Method 1
The knots and multi-strand portion of the elastic string in conjunction with the elasticity of the string generate a random motion of the sack when the sack moves relative to the string
Data Source
AI summary
A training and coordination device including a projectile member such as a ball or sack secured to an elastic string is described. The first end of the elastic string is attached to a location and the second end is connected to the projectile member. At least an end portion of the elastic string secure to the projectile member comprises multiple strands of an odd number. The multiple strands of the elastic string in conjunction with the elasticity of the string generate a random motion of the sack when the sack moves relative to the string.
