Vehicle Spoiler Hinge Access for CHMSL Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accessing and servicing center high mount stop lights (CHMSL) within vehicle spoilers is difficult, often requiring the entire spoiler to be replaced, leading to high costs.
Innovation Solution
A spoiler design with a central bracket and side bracket structures featuring hinge portions that can be opened to access a chamber containing the stop light, allowing for replacement without replacing the entire spoiler.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the stop light is packaged inside the spoiler, then the aerodynamic function is improved, but the ease of repair deteriorates
Solution Approach 1:
The spoiler is divided into multiple segments: a fixed portion and a movable portion connected by a hinge. The movable portion can be opened to provide access to the stop light, while the fixed portion maintains the aerodynamic function. This segmentation allows the stop light to be serviced without replacing the entire spoiler structure.
Solution Approach 2:
The spoiler incorporates a movable portion that can transition between closed and open positions. When closed, it maintains aerodynamic efficiency; when opened, it provides access to the stop light for servicing. This dynamic capability resolves the contradiction between maintaining aerodynamic function and enabling easy repair.
2Device complexity
If the stop light is packaged inside the spoiler, then the compactness is improved, but the ease of operation deteriorates
Solution Approach 1:
The spoiler structure is segmented into fixed and movable portions, allowing the stop light to be accessed by opening the movable portion. This maintains the compact integrated appearance while providing operational access.
Solution Approach 2:
The movable portion acts as an intermediary mechanism that mediates between the need for compact integration and the need for operational access. It provides a controlled opening mechanism that allows servicing without compromising the overall compact structure.
3Reliability
If the entire spoiler is replaced to service the stop light, then the reliability is improved, but the loss of substance deteriorates
Solution Approach 1:
The spoiler is segmented into replaceable and non-replaceable portions. Only the movable portion containing the stop light needs to be removed and replaced, while the main fixed portion with aerodynamic features is retained. This significantly reduces material waste compared to replacing the entire spoiler.
Solution Approach 2:
The stop light and its immediate housing in the movable portion are extracted as a separate serviceable unit. This allows the stop light to be replaced without affecting the main spoiler structure, reducing the amount of material that needs to be discarded.

AI summary
A spoiler for a vehicle has a first end and a second end and includes a first bracket, and a second bracket is arranged opposite to the first bracket with a chamber defined between the first bracket and the second bracket. An opening of the chamber defined at the second end. Moreover, A third bracket is disposed at the second end and extends between the first bracket and the second bracket. The third bracket comprises a central bracket structure arranged substantially centrally to the spoiler, covering the opening, and a pair of side bracket structures. Each side bracket structure includes a hinge portion adapted to be displaced between an open position and a closed position. In the closed position, the hinge portion covers the opening, while in the open position, the hinge portion allows access to the chamber through the opening.
