Elongate Training Tool With Eccentric Particles For Connective Tissue Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training tools with hollow spaces filled with freely movable particles do not effectively provide extra mechanical loading to deeper connective tissue structures, leading to inadequate strengthening and potential injury from sudden impact.
Innovation Solution
A training tool with an elongate hollow space filled with irregularly shaped, eccentric particles that exert a delayed reaction force upon acceleration and deceleration, distributing the mechanical load over time to prevent sudden impact and enhance connective tissue strengthening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a hollow space is filled with freely movable particles, then the total weight can be adjusted, but the connective tissue is not sufficiently loaded during muscle effort
Solution Approach 1:
The hollow space is designed in an elongate configuration rather than a compact shape, enabling the particles to move dynamically along a extended path. This dynamic arrangement ensures that during acceleration and deceleration, particles progressively engage with the holder's ends, creating sustained reactive impact that effectively loads connective tissue throughout the movement range.
Solution Approach 2:
The hollow space is extended in one dimension (elongate design) to create a longer particle travel path. This dimensional change transforms the particle movement from a compact, instantaneous shift to a prolonged, progressive engagement, thereby extending the duration of reactive impact on connective tissue structures.
2Speed
If particles are accelerated and decelerated in a compact space, then the response is immediate, but the impact is too sudden and may cause injury
Solution Approach 1:
The elongate hollow space creates a dynamic particle engagement process where particles progressively contact the holder's ends during acceleration and deceleration. This progressive engagement extends the time duration of force application, transforming sudden impact into a more gradual, sustained reactive impact that reduces injury risk while maintaining training effectiveness.
Solution Approach 2:
The elongate configuration acts as a built-in cushioning mechanism by distributing particle engagement over a longer distance and time. Rather than all particles impacting simultaneously in a compact space, the extended geometry ensures particles engage sequentially, softening the overall impact profile and preventing sudden jolts to the connective tissue.
3Duration of action of stationary object
If the hollow space is made elongate, then the reaction force is distributed over time, but the device complexity increases
Solution Approach 1:
The elongate hollow space can be segmented into multiple sections or compartments, each potentially containing different particle types or densities. This segmentation allows independent optimization of different regions while maintaining the overall elongate configuration, thereby managing complexity through modular design while preserving the time-distributed reaction force benefit.
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 tool provides a soft, resilient impulse that effectively strengthens muscles and connective tissue, reducing the risk of injury by distributing the load over time and targeting deeper tissue structures.
Implementation Method 1
a part of the amount of freely movable particles of solid material does not move relative to the holder, because these particles already rest against the end of the elongate hollow space that is oriented oppositely to the force exerted by the user
Implementation Method 2
the particles are accelerated or decelerated still, so that all particles eventually move at the same speed as the holder. This leads to the above-mentioned special effect, viz. a delayed reaction force on the user
