Motor Vehicle Signaling Module Housing With Reversible Shell Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle signaling modules, such as daytime running lights, require complete replacement when worn or malfunctioning, leading to high costs and complex, potentially damaging maintenance due to their integration within larger housing units, and are susceptible to vibration-induced disturbances.
Innovation Solution
A support housing for motor vehicle signaling modules featuring a lower and upper shell with guide, connecting, and locking members that allow for easy assembly and disassembly without compromising the housing's reliability, enabling interchangeable modules with a flat profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the signaling module is integrated within a larger housing unit sealed with glass fixed by welding, then the housing reliability and sealing are improved, but the maintenance complexity and cost increase significantly requiring complete replacement
Solution Approach 1:
The housing is divided into two separate shells (first shell and second shell) that can be assembled and disassembled independently. The signaling module is contained within one shell, allowing it to be replaced without replacing the entire housing assembly. This segmentation enables maintenance of the module while preserving the housing structure.
Solution Approach 2:
The housing transitions from a static, permanently welded structure to a dynamic, reversible assembly. The locking members enable the housing to be easily assembled and disassembled multiple times, providing operational flexibility for maintenance while maintaining structural integrity during use.
2Strength
If the housing is made as a single piece or assembled by screwing, gluing or riveting, then the structural strength is improved, but the maintenance difficulty and potential for damage increase
Solution Approach 1:
The housing employs reversible locking members that provide strong structural connection during normal operation but can be easily released for maintenance. This dynamic locking mechanism replaces permanent joining methods, enabling both strong assembly and easy disassembly without damage.
Solution Approach 2:
The locking members act as intermediary elements between the two shells, providing a controlled connection mechanism. These intermediaries enable both strong structural integrity during use and easy separation during maintenance, mediating between the conflicting requirements of strength and repairability.
3Reliability
If the signaling module housing is sealed with glass fixed by welding, then the sealing reliability is improved, but the manufacturing complexity and potential for damage increase
Solution Approach 1:
The housing is segmented into separate shells that can be manufactured independently and then assembled using locking members. This segmentation simplifies manufacturing by allowing each shell to be produced separately and assembled later, avoiding complex welded glass sealing in the assembly process.
4Reliability
If the signaling module requires complete replacement upon malfunction, then the reliability is maintained, but the loss of time and cost increase
Solution Approach 1:
The housing is divided into separable shells with the signaling module contained within one shell. This segmentation allows the module to be accessed and replaced independently, reducing maintenance time from complete housing replacement to simple module swap while maintaining system reliability.
Solution Approach 2:
The housing is pre-designed with locking members and guide members that facilitate quick module replacement. The preliminary design of these assembly features enables rapid maintenance operations, reducing the time loss associated with module replacement while ensuring reliable connections.
