Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conducting wires are used for electrical connection between lamp cap and power supply board, then electrical connection can be achieved, but the device volume increases and structure becomes complex due to disorderly wires
Solution Approach 1:
The patent merges the electrical connection function directly into the mounting structure by integrating conducting wires into the heat dissipation unit's mounting holes. The wires are embedded within the structural components rather than being separate discrete elements, thereby achieving electrical connection while maintaining a compact and organized structure without disorderly wire stuffing.
2Reliability
If conducting wires are used for electrical connection, then electrical connection can be achieved, but the device volume increases due to wire stuffing space requirements
Solution Approach 1:
The conducting wires are nested within the mounting holes of the heat dissipation unit structure. The wires are placed inside the existing structural voids rather than occupying additional external space, effectively utilizing the internal volume of the mounting features to accommodate the electrical connection elements without increasing the overall device volume.
3Reliability
If screws are used to press conducting wires, then electrical connection can be achieved, but the soldering points become loose and prone to damage
Solution Approach 1:
The patent extracts the mechanical fastening function from the electrical connection assembly by using separate mounting holes for structural fixation. The screws fasten the heat dissipation unit structure itself, which in turn holds the conducting wires in place through the integrated wire routing, rather than directly clamping the wires with screws. This separation prevents the soldering points from being subjected to mechanical stress and loosening.
4Reliability
If complex terminal structures are used for electrical connection, then connection reliability can be improved, but the device volume and manufacturing cost increase
Solution Approach 1:
The mounting holes in the heat dissipation unit serve multiple functions simultaneously: they provide structural support for mounting components, guide and position the conducting wires, and enable electrical connection. This multi-functionality eliminates the need for separate terminal structures, reducing both volume and manufacturing complexity while maintaining reliable electrical connection.

AI summary
An electrical connection member, for electrically connecting an LED lamp light source plate (20) to a driving plate (30), comprising an input terminal (21) and an output terminal (31). The output terminal (31) is a plate-shaped structure adhered on the surface of a driving plate (30) of the LED lamp. One end of the input terminal (21) is fixed on the light source plate (20) and is electrically connected thereto, and another end of the input terminal (21) has an elastic member structure. After the light source plate (20) is fixed relative to the driving plate (30), the driving plate (30) is provided near to the light source plate (20), and the other end of the input terminal (21) elastically abuts the output terminal (31). By adhering the output terminal (31) on the surface of the driving plate (30), and fixing the input terminal (21) on the light source plate (20), the input terminal (21) elastically abuts the output terminal (31). Since the input terminal (21) is fixed by the driving plate (30), the input terminal (21) has a simple structure, effectively simplifying the entire electrical connection member structure, enabling the electrical connection member to have a simple structure.
