Nested Elastic Tubing Exercise Band Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stretchable exercise bands can cause injury if they suddenly break during use, as they lack sufficient strength to maintain integrity when the outer band fails.
Innovation Solution
The exercise apparatus consists of an elongated outer and inner elastic tubing with a connection mechanism at each end, featuring conical outer and inner connection members and a ball for secure engagement, ensuring the inner tubing remains intact if the outer tubing breaks, thus preventing injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single stretchable band is used for exercise, then the device is simple and easy to use, but the band may suddenly break causing injury to the user
Solution Approach 1:
The patent applies nesting by placing an inner stretchable band inside an outer stretchable band, creating a dual-layer structure where both bands are nested within each other. This nested configuration ensures that if the outer band breaks, the inner band remains intact to prevent injury, while maintaining a relatively compact and integrated band assembly.
Solution Approach 2:
The patent uses composite structure by combining two separate stretchable bands (inner and outer) into a single exercise apparatus. This composite band system provides enhanced reliability through redundancy, where the failure of one band does not compromise the overall safety of the device, as the other band continues to function.
2Reliability
If connection mechanisms are added to interlock inner and outer tubing, then the band maintains integrity when outer tubing breaks, but the device complexity increases
Solution Approach 1:
The connection mechanism is segmented into distinct functional components: an outer connection member with conical outer surface for engaging the outer tubing, and an inner connection member with conical inner surface for engaging the inner tubing. This segmentation allows each component to perform its specific function while maintaining overall system reliability.
Solution Approach 2:
The patent employs conical surfaces (curved geometric forms) for both the outer and inner connection members. The conical outer surface of the outer connection member and the conical inner surface of the inner connection member provide smooth, curved engagement surfaces that facilitate easy insertion and secure locking of the tubings, reducing complexity while maintaining reliability.

Function Achieved in This Case
The design maintains the overall band's integrity and prevents user injury by ensuring the inner tubing remains intact if the outer tubing fails, providing a safer exercise experience.
Implementation Method 1
an elongated outer elastic hollow tubing having opposed ends; an elongated inner elastic hollow tubing having opposed ends
Implementation Method 2
both the outer connection member and the inner connection member are conical for firm engagement with the respective outer and inner elastic tubing

AI summary
An exercise apparatus includes an elongated outer elastic hollow tubing having opposed ends and an elongated inner elastic hollow tubing having opposed ends. A connection mechanism at each of the opposed ends is for interlocking the respective opposed ends of the elongated outer elastic hollow tubing and the elongated inner elastic hollow tubing. A pair of handles is positioned at respective opposed ends of the elongated outer and elongated inner elastic hollow tubings.
