Reusable Locking Device for Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locking systems, such as safety wires, are inefficient in securing connectors due to space constraints, require manual threading, and are not reusable, lacking a positive locking mechanism to prevent movement caused by vibration, temperature, and stress.
Innovation Solution
A locking device comprising a top ring, support structure, and base ring with deformable hinges that provides a secondary locking force by compressing around connectors, preventing unwanted rotation and allowing for easy removal and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If safety wire is used to lock connectors, then locking function is provided, but manual threading and twisting is required which is difficult due to space constraints
Solution Approach 1:
The locking device is divided into separate components: a top ring, a base ring, and support structures with hinges. This segmentation allows the device to be assembled in a compact manner that fits within limited space while maintaining ease of operation through modular construction.
Solution Approach 2:
The locking device incorporates deformable hinges that allow the structure to flex and adapt during installation. This dynamic characteristic enables the device to be easily installed in tight spaces and then maintain a stable locked position, resolving the contradiction between ease of operation and space constraints.
2Reliability
If safety wire is used to lock connectors, then locking function is provided, but the wire is cut after one implementation making re-use unlikely
Solution Approach 1:
The locking device is designed to be recovered and reused after its locking function is fulfilled. The reversible attachment mechanism allows the device to be removed from the connectors and reused, eliminating the need to discard it after a single use and thereby improving both reliability through consistent locking performance and ease of repair through reusability.
3Loss of information
If griptol line is added between connected devices, then visual cue for movement is provided, but it only indicates movement rather than acting as positive locking
Solution Approach 1:
The locking device merges the functions of positive mechanical locking with movement indication into a single integrated structure. The support structures with hinges provide both the locking force through their rigid connection and visual indication through their deformable nature, eliminating the need for separate griptol lines and providing both locking force and movement detection capabilities.
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 locking device effectively secures connectors against vibration, temperature, and stress-induced movement, offering a reusable and space-efficient solution that complements existing locking methods by providing a positive locking mechanism without wrapping around the entire circumference.
Implementation Method 1
A locking device 100 is provided which includes a top ring 110, a support structure 120 and a base ring 130. The support structure 120 may include deformable hinges 140, 150 that present a locking force onto the paired connectors.
