Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for attaching auxiliary weight-bearing items to shoulder straps suffer from uneven weight distribution, balance issues, and limited compatibility with different strapping systems, leading to strap wear and accessibility problems.
Innovation Solution
A clip with a hinged design and non-slip strap-engaging surfaces that securely attaches auxiliary items to any strap system, providing improved weight distribution and balance through a closure mechanism with stabilizing features and flexible positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional devices are used to attach auxiliary items to shoulder straps, then items can be attached, but weight distribution becomes uneven causing pain and balance issues
Solution Approach 1:
The clip device is designed to attach auxiliary items in a position that counterbalances the weight distribution on the shoulder strap. By strategically positioning the clip and distributing the load across multiple attachment points on the strap, the device creates a counterbalancing effect that prevents uneven weight concentration, thereby reducing pain and maintaining user balance.
2Ease of operation
If conventional devices allow item attachment, then accessibility is improved, but strap wear increases due to unexpected tensions
Solution Approach 1:
The clip device features localized reinforcement at critical stress points where the strap contacts the clip. The design includes strengthened engagement surfaces and distributed load-bearing structures that concentrate support where tensions are highest, preventing excessive wear on the strap while maintaining easy item accessibility.
3Adaptability or versatility
If conventional devices are used for attaching items, then attachment is possible, but the devices are specific to one strapping system and not interchangeable
Solution Approach 1:
The clip device is designed with universal attachment mechanisms that can engage with various types of shoulder straps and strapping systems. The clip features standardized engagement surfaces and adjustable positioning capabilities that allow it to function effectively across different strap configurations, eliminating the need for multiple specialized devices.
4Strength
If conventional devices attach items to straps, then items can be secured, but the added weight creates vertical and horizontal tensions causing imbalance
Solution Approach 1:
The clip device incorporates asymmetric design elements that allow for adjustable positioning along the shoulder strap. By enabling asymmetric placement of the clip relative to the strap and user body, the device can be configured to counterbalance the auxiliary item's weight, maintaining system equilibrium while ensuring secure attachment.
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 clip effectively distributes weight evenly, prevents slippage, and allows for secure attachment of heavier items across various strapping systems, enhancing balance and accessibility.
Implementation Method 1
At least one of the top and bottom surfaces comprising strap-engaging, non-slip structure

AI summary
A clip attaches an item, including a weight bearing item, to a strap worn by a person. The clip includes a body and a closure mechanism. The body has bottom and top portions connected by a hinge movable between a closed position, to capture the strap between, and an open position. At least one of the top and bottom surfaces has strap-engaging, non-slip structure to securely engage the strap captured therebetween. The closure mechanism includes closure structure at closure ends of the top and bottom portions and a stabilizer preventing relative movement of the closure ends generally parallel to the hinge axis when the clip is in the closed position. The clip can include a fastener supported by the body, the fastener being configured for attachment of the item to the clip.
