Rotating Strike Arm With Elastic Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Martial arts and boxing practitioners face limitations in training with existing padded surfaces, as they lack adjustable resistance and dynamic movement simulation, which are essential for effective practice and skill development.
Innovation Solution
A modular strike practice system featuring rotatable striking arms with adjustable elastic bands that provide controlled rotational motion, allowing for customizable resistance and rebound, enabling practitioners to simulate various striking techniques and improve skills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional padded surfaces (heavy bags, focus mitts) are used for strike practice, then practitioners can perform basic striking drills, but the equipment lacks adjustable resistance and dynamic movement simulation
Solution Approach 1:
The striking arms are designed to be rotatably mounted on the framework, allowing them to move dynamically during striking practice. The elastic bands provide variable resistance that adapts to the force and direction of strikes, creating a dynamic training experience rather than static resistance
Solution Approach 2:
The system is divided into modular components: a framework, multiple rotatable striking arms, and elastic bands that can be independently adjusted. This segmentation allows practitioners to configure different resistance levels and movement patterns by repositioning or removing specific components
2Adaptability or versatility
If elastic bands are added to control rotational motion of striking arms, then adjustable resistance and rebound are achieved, but the device complexity increases
Solution Approach 1:
The elastic bands allow practitioners to change the resistance parameter by adjusting band tension, selection of different band stiffness levels, or modification of attachment positions. This provides customizable resistance without requiring multiple complete equipment sets
Solution Approach 2:
The elastic bands act as an intermediary mechanism between the practitioner's strike and the striking arm's rotational motion. They mediate the force transfer, providing controlled resistance and rebound while isolating the complexity of the resistance mechanism from the basic striking action
3Ease of operation
If striking arms are configured to rotate freely without elastic bands, then the system is simpler to operate, but adjustable resistance and controlled rebound are lost
Solution Approach 1:
The striking arm system is designed to perform multiple functions: it can rotate freely for unresisted practice, use elastic bands for resisted practice, and be configured in various positions to simulate different movement patterns. This multi-functionality allows a single system to replace multiple specialized training tools
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 system enhances training by offering adjustable resistance and dynamic movement simulation, allowing practitioners to practice a range of techniques with improved hand-eye coordination, timing, and strength, catering to different skill levels and practice modes.
Implementation Method 1
elastic bands can be attached between a portion of the framework and a portion of an arm to control rotational motion of the striking arm, for example, to cause the striking arm to return toward a pre-strike position after being struck by a practitioner
Data Source
AI summary
A strike practice assembly includes a striking arm, a framework for supporting said striking arm and providing a rotational axis therefor, and, optionally, one or more elastic band members that can be configured to resiliently return said striking arm to a pre-strike position after being struck.
