Grappling Dummy Spring Mechanism for Human-Like Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grappling dummies fail to provide realistic training for practitioners due to their inability to approximate human movement, strength, and stance, and they do not exert force in return, making training sessions less effective for preparing practitioners for human responses.
Innovation Solution
A grappling dummy apparatus with a rigid frame shaped like a human body, equipped with a brace piece and springs that allow biasable movement, simulating human-like articulation and force response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional grappling dummy is used, then it provides a training target for practitioners, but it does not exert force in return and fails to approximate human movement and strength
Solution Approach 1:
The grappling dummy incorporates movable portions connected by springs that allow dynamic movement and force exertion. The springs enable the movable portions to move relative to each other and return to initial positions, creating a dynamic system that approximates human movement and resistance rather than a static dummy structure.
Solution Approach 2:
The dummy uses spring constants and pre-loads to control the force characteristics. By adjusting spring parameters, the dummy can exert varying amounts of force in different directions, allowing practitioners to experience realistic resistance during training exercises.
2Stability of the object's composition
If a rigid training dummy is used, then it maintains structural stability, but it cannot simulate human-like articulation and movement response
Solution Approach 1:
The dummy is divided into multiple movable portions (head, torso, arms, legs) that can move independently relative to each other. This segmentation allows each body part to simulate natural human articulation and movement while the overall frame maintains structural stability through the spring connections.
3Use of energy by moving object
If a static grappling dummy is used, then it requires no power source, but it cannot provide force feedback or resistance to practitioners
Solution Approach 1:
The spring mechanism provides force feedback automatically without requiring an external power source. When practitioners apply force to the movable portions, the springs compress or extend and exert reactive force back on the practitioner, creating a self-service force feedback system that consumes no electrical energy.

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 apparatus allows for more realistic and effective training by enabling practitioners to practice movements that simulate human-like resistance and response, enhancing their preparation for engaging with real persons.
Implementation Method 1
At least one spring is connected to two adjacent portions of the rigid frame. The portions of the rigid frame connected by the at least one spring are biasably movable.
