Strap Retention Device for Tensioning Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tensioning devices often fail to securely retain adjustable straps, leading to unwanted slippage or complete dislodgment, which necessitates repeated adjustments and can cause frustration during securing objects.
Innovation Solution
A retention device comprising a top plate and bottom plate, configured to sandwich the adjustable strap and prevent it from pulling through the tensioning device, utilizing recessed portions, protrusions, and connectors such as screws or VELCRO-like strips to securely hold the strap in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple tensioning device is used, then the device complexity is low, but the strap can slip or dislodge from the device
Solution Approach 1:
The retention device is divided into separate top and bottom plates that can be independently positioned and connected, allowing each plate to engage with the strap separately for enhanced retention while maintaining overall device simplicity
Solution Approach 2:
The retention device nests within the existing tensioning device structure, with the top and bottom plates positioning around the strap and connecting together to form an integrated retention system without requiring complete device redesign
2Reliability
If a retention device with multiple components is used, then the strap retention is improved, but the ease of manufacture decreases
Solution Approach 1:
The retention device is divided into separate top and bottom plates that can be independently positioned and connected, allowing each plate to engage with the strap separately for enhanced retention while maintaining overall device simplicity
Solution Approach 2:
The top and bottom plates are designed with universal engagement features that can work with various strap types and tensioning device configurations, allowing the same basic design to be manufactured and applied across different applications

Function Achieved in This Case
Effectively prevents the adjustable strap from pulling through the tensioning device, maintaining the desired length and reducing the need for repeated adjustments, thereby enhancing the security and usability of strap-based systems like tie-downs and backpacks.
Implementation Method 1
utilizing recessed portions, protrusions, and connectors such as screws or VELCRO-like strips to securely hold the strap in place
Implementation Method 2
utilizing recessed portions, protrusions, and connectors such as screws or VELCRO-like strips to securely hold the strap in place

AI summary
A retention device can be used with an adjustable strap. The adjustable strap can be part of a tie down strap system, a backpack, or a fanny pack. A free end of the adjustable strap can be inserted and pulled through a tensioning device. The retention device can be placed around a portion of the adjustable strap adjacent to the tensioning device. The retention device can prevent the adjustable strap from undesirably pulling back through the tensioning device. The retention device can include a top plate and bottom plate that sandwich the strap and then connected to each other. The retention device can also be a strip of material that includes a plurality of tiny loops and a plurality of tiny flexible hooks that are used to attach to the adjustable strap and wrap around the strap.
