Vehicle Lighting Card Support Device with Perpendicular Connector Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle lighting and signaling modules face challenges in easy maintenance of electronic control cards due to cumbersome electrical cables and interference with other components, as previous arrangements do not facilitate simple assembly and disassembly or connector extraction.
Innovation Solution
A device with a frame featuring parallel grooves for sliding card support and a perpendicular housing for a removable electrical connector, including a guide pivot, wedging stop, and flexible locking lug, allowing easy access and disconnection of the card without cable stretching, integrated within the module housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sufficient length of electrical cable is provided inside the box to enable card removal, then the card can be easily removed and connectors accessed, but the cable becomes cumbersome and creates interference with other functional components
Solution Approach 1:
The device is segmented into two functional housings: a first housing for card support and a second housing for connector retention. This segmentation allows the card and connector to be accessed independently without requiring long cables, as the connector housing is positioned adjacent to the card housing within the same frame structure.
Solution Approach 2:
The card support housing and connector retention housing are merged into a single integrated frame structure. This merging eliminates the need for separate cable connections between distant components, as both the card and connector are housed within the same structural unit, thereby reducing cable length and interference.
2Weight of stationary object
If the electronic card is enclosed in the casing, then the module structure is compact, but maintenance services require cutting out a wall to access the card
Solution Approach 1:
The card support housing and connector retention housing are designed as removable components from the frame. This dynamic design allows the card to be accessed for maintenance by simply removing the housing, eliminating the need to cut walls in a fully enclosed casing while maintaining a compact overall structure.
Solution Approach 2:
The card support housing and connector retention housing are nested within the overall module housing structure. This nesting allows the card to be enclosed within the compact module while providing easy access through removable inner housings, combining compactness with maintenance accessibility.
3Adaptability or versatility
If previous arrangements are used for card support, then the card can be housed, but assembly and disassembly are not facilitated and connector extraction is difficult
Solution Approach 1:
The support structure is segmented into a card support housing and a connector retention housing that can be independently removed from the frame. This segmentation facilitates easy assembly and disassembly of the card, as each housing can be accessed and removed separately without affecting the other components.
Solution Approach 2:
The housing components are designed with dynamic removability, allowing the card support housing and connector retention housing to be easily attached to and detached from the frame. This dynamic design enables simple assembly and disassembly operations while providing secure housing for the card and connector.
