Removable Operating Element for Vehicle Light Bulb Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle lighting and signaling devices require users to perform complex rotational and translational movements to replace bulbs, making it difficult and tedious, often necessitating professional assistance due to bulb placement near protective glass, increasing service costs and vehicle immobilization.
Innovation Solution
A signaling and/or lighting device with a removable maneuvering element that allows manual actuation of the support relative to the housing, featuring first and second coupling elements for reversible cooperation, enabling easy assembly and disassembly, and snap-fastening elements for secure fixation, facilitating bulb replacement without requiring extensive user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bulb holder is attached to the housing using a bayonet fitting requiring rotational movement, then the bulb holder is securely fixed, but the bulb replacement operation becomes complex and difficult to perform
Solution Approach 1:
The invention separates the bulb holder from the housing by introducing a removable operating element that acts as an intermediary. The operating element can be detached and reattached, allowing the bulb holder to be released without complex rotational movements. This segmentation transforms a single complex fixation mechanism into separable, simpler components that are easier to manipulate during bulb replacement.
2Shape
If the bulb is placed near the protective lens for aesthetic reasons, then the visual appearance is improved, but the accessibility of the bulb holder for user operation is reduced
Solution Approach 1:
The removable operating element serves as a mediator between the user and the bulb holder. It provides an extended leverage point that allows users to access and manipulate the bulb holder from outside the housing, overcoming the accessibility problem created by placing the bulb near the protective lens. The operating element transmits user force to the bulb holder without requiring direct access to the bulb holder's location.
3Ease of operation
If the bulb holder is made removable for easy bulb replacement, then the ease of operation is improved, but the device complexity increases due to additional components
Solution Approach 1:
The removable operating element is designed with universal functionality to work with different types of bulb holders and housing configurations. By creating a standardized interface system with coupling elements on both the operating element and housing, the invention reduces overall complexity through standardization rather than increasing it with custom components for each application.
