Quick Exchange Handle With Nested Wedge Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resistance band systems lack secure and efficient mechanisms for holding and exchanging resistance tubing, leading to potential safety issues and time-consuming processes.
Innovation Solution
The proposed system includes handles with nested wedges that form a funnel-shaped channel to securely grip resistance bands, featuring a locking mechanism that allows for easy interchangeability by adjusting the position of the wedges, ensuring the band remains secure during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handle is permanently affixed on each end of resistance tubing, then the connection is secure and safe, but the tubing cannot be exchanged and the system lacks versatility
Solution Approach 1:
The handle is divided into two separate components: a stationary housing and a movable wedge. This segmentation allows the wedge to be inserted and removed independently, enabling tubing exchange while maintaining secure connection during use. The wedge can be locked into position to firmly hold the tubing or released to allow removal.
Solution Approach 2:
The wedge is designed to be movable between different positions within the housing. It can be pushed into a locked position where it firmly grips the tubing, or pulled back to a released position where the tubing can be removed. This dynamic mechanism provides both security during exercise and ease of exchange when needed.
2Ease of operation
If a cutout for resistance tubing is provided in the handle, then the tubing can be placed in place, but the system is time consuming and difficult to exchange tubing
Solution Approach 1:
The wedge is pre-positioned within the housing in a ready state, requiring no assembly or preparation before use. The user simply needs to insert the tubing and push the wedge into its locked position, eliminating time-consuming assembly steps. The preliminary positioning of the wedge allows for rapid tubing exchange.
3Adaptability or versatility
If a sliding mechanism is used to slide the handle up and down to place tubing within the housing, then the tubing can be exchanged, but the mechanism does not securely and safely hold resistance tubing in place
Solution Approach 1:
The wedge acts as an intermediary element between the housing and the tubing. When locked into position, the wedge creates a firm mechanical grip on the tubing through its angled surface, providing secure retention. When released, the wedge moves back to allow easy removal. This intermediary mechanism provides both security and exchange capability.
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 system provides a safe and efficient method for securely holding and easily exchanging resistance bands, allowing for multiple exercise options with a single set of handles, ensuring stability and versatility.
Implementation Method 1
The handle is adapted to grip the resistance band with greater force when force is applied to the resistance band
Implementation Method 2
the pair of wedges are fully nested within the housing, and positioned adjacently facing each other to form a funnel-shaped accessory channel therebetween
Implementation Method 3
The funnel-shaped accessory channel has a larger diameter towards the grip end of the housing and a smaller diameter towards the accessory end of the housing. A grip extends from the grip end of the housing. When the wedges are in the first position, a conical protrusion or collar at an end of the accessory may be captured within the funnel-shaped accessory channel formed between the wedges.

AI summary
The resistance band system of the disclosure includes one or more resistance bands, and a pair of handles which secure the ends of the one or more resistance bands. Each handle locks onto one of the ends of each resistance band. The handle is adapted to grip the resistance band with greater force when force is applied to the resistance band, such as when it is in use. The handle unlocks to release the ends of one or more of the resistance bands from the handles for changing of one or more of the resistance bands.
