Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply devices do not adequately address the positioning of circuit boards for efficient coupling, leading to potential misalignment and increased manufacturing costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If circuit boards are coupled without positioning structures, then device complexity is reduced, but manufacturing precision deteriorates due to misalignment
Solution Approach 1:
The patent introduces circuit board coupling members as intermediary components between the first and second circuit boards. These coupling members include positioning protrusions that fit into positioning holes on the circuit boards, serving as a mediating mechanism to achieve precise alignment without directly coupling the boards. This resolves the contradiction by adding a positioning intermediary that improves alignment precision while keeping the overall coupling structure relatively simple.
2Manufacturing precision
If positioning holes are added to circuit boards, then manufacturing precision is improved through better alignment, but device complexity increases
Solution Approach 1:
The patent segments the positioning function from the circuit board structure itself by introducing separate coupling members with positioning protrusions. Instead of adding complex positioning features directly to the circuit boards, the positioning functionality is segmented into dedicated coupling members that interface with simple positioning holes. This reduces the complexity increase while maintaining manufacturing precision.
3Reliability
If multiple coupling members are used to ensure stable coupling, then reliability is improved, but device complexity increases
Solution Approach 1:
The circuit board coupling members are designed to perform multiple functions simultaneously: they provide mechanical coupling between the circuit boards, ensure precise positioning through protrusion-hole engagement, and maintain stable connection. This multi-functionality allows a single component type to address multiple requirements, improving reliability without proportionally increasing device complexity.

AI summary
A power supply device includes a first circuit board, a second circuit, and a plurality of circuit board coupling members. Each of the circuit board coupling members includes a body portion, a first protruding portion, and a second protruding portion. The body portion determines positions of the first circuit board and the second circuit board. The first protruding portion positions the body portion relative to the first circuit board. The second protruding portion positions the body portion relative to the second circuit board. A plurality of first positioning holes in which the first protruding portions are fitted is formed in the first circuit board. A plurality of second positioning holes in which the second protruding portions are fitted is formed in the second circuit board.
