Vehicle Lighting Socket Notch for Soldering Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to facilitate easy soldering of light emitting diodes (LEDs) in vehicle lighting devices with a compact socket design, where the distance between the LED unit and power feeding terminals is short, making soldering difficult due to space constraints.
Innovation Solution
The design incorporates a mounting unit with a recessed portion and protruding power feeding terminals, featuring a notch portion on the side face that provides a 2 mm or more distance from the terminals, and includes bayonets for secure attachment, allowing for efficient soldering and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the external dimension of the end portion of the socket is reduced to enable use in popular vehicles, then the lighting device can be installed in more vehicle types, but the distance between the side face of the recessed portion and the power feeding terminal becomes short, making soldering difficult
Solution Approach 1:
The patent introduces a notch portion that creates additional spatial dimension at the corner of the recessed portion, allowing the soldering iron to approach from a different spatial angle. This dimensional adjustment provides sufficient working space for soldering operations without increasing the overall external dimensions of the socket end portion, thus resolving the contradiction between compact size and soldering accessibility.
2Volume of moving object
If the external dimension of the end portion of the socket is reduced, then the lighting device becomes more compact for popular vehicle installation, but the structural integrity of the socket may be compromised during assembly
Solution Approach 1:
The notch portion is strategically positioned at the corner of the recessed portion where structural reinforcement is most needed. By locally modifying the geometry at this critical location, the patent enhances the socket's resistance to damage during assembly without increasing the overall external dimensions. The notch creates a more robust structural configuration at the stress-prone corner region while maintaining compact overall size.
