Dual-Resistance Exercise Mechanism for Continuous Push-Pull Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise equipment fails to effectively activate and release opposing muscle groups through pulling and pushing movements in the same plane without changing body position, leading to reduced coordination, muscle tone, and elasticity.
Innovation Solution
An exercise device with a helical spring and elastic band mechanism that maintains equilibrium, allowing for dual-resistance transfer between pulling and pushing movements, leveraging stored elastic energy for efficient muscle activation and respiratory training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional exercise equipment is used for muscle activation and release, then muscle training can be performed, but stored elastic energy dissipates when body position or equipment changes between pulling and pushing, resulting in reduced coordination, muscle tone, and elasticity
Solution Approach 1:
The device maintains continuous elastic energy storage and transfer between pulling and pushing movements through the integrated spring and elastic band system. The spring remains compressed and the elastic band remains extended throughout the exercise cycle, eliminating energy dissipation that occurs when conventional equipment requires position changes between exercises.
Solution Approach 2:
The patent combines both compression (spring) and extension (elastic band) resistance elements into a single integrated device that performs both pulling and pushing movements. This merging allows reciprocal muscle groups to be trained continuously without changing body position or equipment, maintaining elastic energy storage throughout the exercise sequence.
2Adaptability or versatility
If a single exercise apparatus is designed to provide both pulling and pushing resistance, then reciprocal muscle training can be achieved, but the device complexity increases compared to conventional single-function equipment
Solution Approach 1:
The elastic band is threaded through the cavity formed by the base and insert, with the spring positioned within the same cavity. This nested arrangement allows both compression and extension elements to occupy the same space, providing dual-resistance functionality without requiring separate equipment or complex mechanical linkages.
Solution Approach 2:
The single device structure with handles connected by the extension element provides both pulling and pushing resistance capabilities. The same basic apparatus configuration serves multiple functions (bicep curls, tricep extensions, chest presses, rowing movements) by simply changing the direction of force application, eliminating the need for multiple separate equipment pieces.
3Length of moving object
If the spring is completely relaxed during pushing movements, then full extension range is achieved, but the device cannot maintain equilibrium and component stability
Solution Approach 1:
The spring is pre-compressed and the elastic band is pre-stretched in the equilibrium position before any exercise movement begins. This preliminary tensioning ensures that both elements remain under tension throughout the full range of motion, maintaining device stability and equilibrium while still allowing complete extension and compression ranges during exercise execution.
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
Enhances muscle strength and respiratory capacity by harmonizing lengthening and compressive resistances, providing a portable and versatile tool for core muscle training and breathing exercises.
Implementation Method 1
a compression element (e.g., a helical spring) located within a cavity formed by the base and the insert
Implementation Method 2
the spring is slightly compressed and the elastic band is slightly extended with the resulting forces keeping the components of the device together
Implementation Method 3
an extension element (e.g., an elastic band) extending through the cavity
Implementation Method 4
When the opposing handles are moved further apart, the elastic band is further extended, but the spring is not totally relaxed
Implementation Method 5
dual-resistance transfer function which harmonizes lengthening (pulling) and compressive (pushing) resistances so that the stored energy of each action, when released, is transferred to the opposing action

AI summary
An exercise device having an insert slidably coupled within a base; a compression element (e.g., a helical spring) located within a cavity formed by the base and the insert; an extension element (e.g., an elastic band) extending through the cavity; and opposing handles connected to opposing ends of the extension element. When the device is in its equilibrium state with no external longitudinal forces applied to the handles, the spring is slightly compressed and the elastic band is slightly extended with the resulting forces keeping the components of the device together. When the opposing handles are moved closer together, the elastic band is relaxed and the spring is further compressed. When the opposing handles are moved further apart, the elastic band is further extended, but the spring is not relaxed.
