Variable Thickness Elastic Band for Uniform Exercise Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise tubing provides uneven tension during exercise movements, leading to inadequate muscle stimulation and improper technique due to low initial tension and rapid resistance increase towards the end of the movement, which is less effective compared to free weights or exercise machines.
Innovation Solution
A resistance training apparatus with a modified elastic band or tubing that maintains substantially constant tension throughout an exercise movement by varying the thickness, diameter, or width along its length, ensuring consistent resistance and increased muscle stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional exercise tubing is used, then the device is lightweight and versatile, but the tension increases dramatically near the completion of the movement, causing uneven resistance throughout the exercise
Solution Approach 1:
The tubing is designed with varying thickness along its length, creating different local stiffness characteristics. The thicker portion provides higher resistance when stretched less, while the thinner portion provides lower resistance when stretched more, resulting in substantially uniform tension throughout the exercise movement range.
2Ease of operation
If conventional exercise tubing is used, then the device is not intimidating and can be used in any setting, but the low initial tension does not provide sufficient muscle stimulation
Solution Approach 1:
The tubing incorporates a thicker section that provides higher resistance at the beginning of the movement when stretched minimally. This ensures sufficient initial muscle stimulation while maintaining the overall accessibility and ease of use of the exercise device.
3Weight of moving object
If conventional exercise tubing is used, then the device is lightweight and portable, but the rapid resistance increase towards the end of movement forces users to accelerate speed, causing improper technique
Solution Approach 1:
The tubing is designed with a thicker section that maintains uniform tension throughout the movement range, preventing the rapid resistance increase that occurs with conventional tubing. This allows users to maintain proper exercise technique without accelerating movement speed, while the device remains lightweight and portable.
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 apparatus provides greater resistance earlier in the exercise movement and maintains consistent resistance levels, enhancing muscle stimulation and training results by avoiding the need to accelerate movement speed, thus improving exercise technique and effectiveness.

AI summary
A resistance training apparatus provides an elastic member for use in exercise strength training and fitness conditioning. The resistance training apparatus beneficially provides a user with a more consistent and even resistance tension throughout an exercise movement. The resistance training apparatus also provides for a greater training effect on an engaged muscle or muscle group.
