Airport Runway Lighting Module With Detachable Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airport runway lighting devices have complex component exchange processes, requiring detachment of lighting units and additional cover ring removal for maintenance, leading to increased repair costs and a non-compact structure.
Innovation Solution
A lighting device with a combined light source and reflector on a common carrier, detachably connected to the base support, featuring a replaceable circumferential seal for tool-free lens exchange, allowing for quick module replacement and a compact, flat design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lighting unit is designed with a housing and cover ring structure, then the lighting unit has protection and structural integrity, but the exchange of components becomes complex and time-consuming
Solution Approach 1:
The lighting device is divided into modular components: the lighting unit with housing and cover ring can be detached as a module, and within it, the lens becomes a separately replaceable component. This segmentation allows the lens to be exchanged independently without removing the entire lighting unit or cover ring, resolving the contradiction between structural integrity and ease of repair.
2Stability of the object's composition
If the lens is firmly fixed in the base support, then the lens has stable positioning, but the lens cannot be easily replaced for maintenance
Solution Approach 1:
The lens mounting structure transitions from a fixed state to a dynamically adjustable state. The lens can be firmly fixed during operation for stable positioning, but can be quickly released and replaced when maintenance is needed. This dynamic characteristic resolves the contradiction between stable positioning and ease of replacement.
3Ease of manufacture
If the lighting module has a large transverse extension, then the lighting components can be properly arranged, but the overall structure becomes non-compact and bulky
Solution Approach 1:
The lighting components are arranged in a vertically stacked configuration rather than spreading out horizontally. The light source, reflector, and lens are positioned one above the other along the vertical axis, creating a compact structure that maintains proper component arrangement while minimizing transverse extension.
