Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If bulky resistive circuits are used for heat dissipation in connection devices, then heat dissipation capability is improved, but device dimensions increase and shadowing of LEDs occurs
Solution Approach 1:
The patent extracts the heat dissipation function from bulky resistive circuits and implements it through thin arms (140) that extend from the connection frame. These arms are specifically designed to dissipate heat without occupying significant space, thereby resolving the contradiction between heat dissipation capability and device dimensions.
Solution Approach 2:
The patent employs thin arms (140) as heat dissipation structures instead of bulky resistive circuits. These thin structures provide adequate thermal management while minimizing the volume they occupy, thus preventing shadowing of LEDs and reducing overall device dimensions.
2Reliability
If dedicated connectors with standardized sockets are used, then electrical connection reliability is improved, but device height increases and LED placement flexibility is reduced
Solution Approach 1:
The patent extracts the electrical connection function from dedicated connectors with standardized sockets and implements it through crimping terminals (132) that can be directly crimped to connection elements. This eliminates the need for bulky socket housings, reducing device height while maintaining connection reliability.
Solution Approach 2:
Instead of using a connector housing that encloses the connection interface (traditional approach), the patent inverts the approach by using exposed crimping terminals that make direct contact. This inversion eliminates the height constraint imposed by standardized socket housings while preserving electrical connection reliability.
3Temperature
If resistive circuits are sized for specific applications, then heat dissipation effectiveness is improved, but manufacturing complexity and production difficulty increase
Solution Approach 1:
The patent designs the connection frame with arms (140) that serve as universal heat dissipation structures applicable across multiple applications. Unlike application-specific resistive circuits, these arms provide adequate heat dissipation for various LED configurations without requiring customization, thereby improving ease of manufacture and production versatility.
Solution Approach 2:
The patent employs arms with varying dimensions and configurations that can be adjusted through parameter changes rather than complete redesign. This allows the same basic structure to effectively dissipate heat across different applications while maintaining manufacturing simplicity and production versatility.

AI summary
The invention relates to an electrical connection device (100) for at least one light source having an electrical power supply device. The device (100) is used, in particular, in a light device for a motor vehicle and enables the placing of light sources at a distance from the connection element (110, 120, 130), which can in turn be placed at a distance from an electrical power supply device for the light sources. The connection device allows great freedom of location for light sources with respect to the device, since the device provides only little shadow on the light sources while ensuring good dissipation of the heat produced by same.
