Dual Locking Assembly for Reusable Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems for straps lack efficiency and economy in design, failing to provide a reusable and volumetrically efficient solution for securing items without requiring special tools or compromising durability.
Innovation Solution
A dual locking assembly comprising rectangular lock and strap assemblies with specularly positioned locking tabs and serrations, allowing the strap to be inserted and reused multiple times by cutting unused sections, enabling secure item binding without the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional single-loop strap with basic locking mechanism is used, then the device can be carried by law enforcement personnel, but it lacks durability and cannot be reused
Solution Approach 1:
The strap is divided into multiple loops (first loop and second loop) with distinct functions - the first loop provides initial securing while the second loop provides reinforcement. This segmentation allows each loop to be optimized for its specific role, improving overall reliability without requiring a single overly complex locking mechanism
Solution Approach 2:
The strap is pre-formed with two complete loops and a pre-attached locking mechanism, allowing law enforcement personnel to carry it in a compact form while having it instantly ready for use. The dual-loop configuration is prepared in advance to provide both initial securing and reinforcement capabilities
2Adaptability or versatility
If a disposable restraining device is used, then it can be carried in compact form, but it cannot be reused and requires frequent replacement
Solution Approach 1:
Instead of discarding the entire strap after one use, the design allows for selective replacement - only the strap portion that becomes worn or contaminated needs to be replaced, while the locking mechanism can be reused. The dual-loop design enables the strap to be cut and reconfigured for continued use
Solution Approach 2:
The invention reverses the traditional disposable approach by making the strap reusable through its dual-loop design. The strap can be cut to size and reconfigured multiple times, eliminating the need for frequent replacement and reducing material consumption over time
3Reliability
If a complex dual-loop reinforcement system is implemented, then binding security is improved, but storage efficiency decreases
Solution Approach 1:
The strap can be folded and nested within itself, with the second loop providing reinforcement while allowing the entire assembly to be compacted into a small form factor for portable storage. The locking mechanism is designed to accommodate this nested configuration
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 dual locking assembly provides a durable, reliable, and cost-effective means to securely bind items, allowing for repeated use of the strap and lock components, enhancing usability and storage efficiency.
Implementation Method 1
The first face comprises serrations... the serrations are facing respective first and second locking tabs to engage, and lock the strap at a predetermined section

AI summary
A dual locking assembly for straps, which has a lock assembly having first and second strap passages positioned opposite each other, and a strap assembly having a strap. The lock assembly and the strap assembly are reusable. The lock assembly is rectangular in shape. The first and second strap passages have first and second locking tabs respectively. The first and second locking tabs are specularly positioned. The strap has first and second ends, and first and second faces, whereby the first face has serrations. The strap assembly is inserted through the lock assembly, whereby a first section of the strap is used to secure an item or a plurality of items while a second section of the strap is cut to be reused. When the strap assembly is inserted through the lock assembly, the serrations are at the outer side of the strap.
