Movable-Arm Training Device for Dynamic Martial Arts Practice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing martial arts training dummies are static and lack dynamic interaction, failing to simulate the responsiveness of a live partner, limiting the effectiveness of training.
Innovation Solution
An exercise training device featuring a main pole with movable training arms, collar clamps, ball bearings, and a base that stabilizes the structure, allowing for dynamic movement and simulation of live partner training, along with a spring mechanism for added responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If training dummies are made as static structures with immovable parts, then structural stability is improved, but training realism and dynamic interaction deteriorate
Solution Approach 1:
The training dummy incorporates multiple movable arms with rotational joints that can dynamically respond to user inputs. The arms are connected via ball bearings and collar clamps to the main pole, allowing them to rotate and move in response to force application, transforming the static structure into a dynamic training system that simulates live partner interaction
2Adaptability or versatility
If training dummies are made with movable parts to simulate live partner, then training realism is improved, but structural stability and control deteriorate
Solution Approach 1:
The training dummy is divided into multiple independent segments - the main pole and multiple training arms - each capable of independent movement. The arms are secured to the main pole through collar clamps that allow rotational movement while maintaining structural connection, enabling realistic dynamic interaction while preserving overall structural integrity
Solution Approach 2:
Ball bearings are introduced as intermediary elements between the training arms and the main pole. These ball bearings facilitate smooth rotational movement of the arms while maintaining stable connection to the main pole, resolving the contradiction between movement capability and structural stability
3Productivity
If multiple movable training arms are added to simulate partner movements, then training effectiveness is improved, but device complexity increases
Solution Approach 1:
Multiple training arms are mounted on a single main pole structure, with each arm serving as an independent training target. The collar clamp and ball bearing mechanism serves as a universal connection system that simplifies the attachment and movement control of multiple arms, reducing the overall complexity compared to having separate structures for each arm
