Airfield Light Threaded Insert for Stripped Thread Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airfield light fixtures face issues with bolt rusting, breaking, and stripping, leading to damaged threadings that require on-site repair, which is cumbersome and inefficient.
Innovation Solution
A threaded insert made of thermoplastics, composites, or metals like 316 Stainless Steel, featuring a tapered design and protrusions, is used to repair or replace damaged threadings in airfield light fixtures, ensuring secure installation and preventing stripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bolts are used to secure the cover to the container, then the light fixture can be assembled and disassembled for maintenance, but the bolts rust and break within the threaded opening or strip the threading upon removal
Solution Approach 1:
The threaded insert is divided into two functional parts: an external threading section that engages with the container wall, and an internal threading section that receives the bolt. This segmentation allows the insert to be installed once and reused multiple times, eliminating the problem of bolt-induced threading damage while maintaining ease of assembly and disassembly for maintenance.
2Productivity
If threaded openings are used to secure bolts, then the container can be assembled with the cover, but the threaded openings become blocked or damaged requiring on-site repair
Solution Approach 1:
The threaded insert is pre-installed into the container during manufacturing, before the light fixture is deployed to the field. This preliminary action ensures that the threaded openings are already prepared and protected, eliminating the need for on-site repair operations when bolts need to be removed and reinstalled during maintenance cycles.
3Device complexity
If standard threaded holes are used in the container, then the structure remains simple, but the threadings require repair when bolts break or strip
Solution Approach 1:
The threaded insert acts as an intermediary component between the container wall and the bolt. Instead of threading the bolt directly into the container (which causes stripping and damage), the insert mediates the connection by providing a reusable threaded interface. This adds a single component but eliminates the need for repair operations, improving overall reliability.
