Lateral Board Coupling Structure for Circuit Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing multi-layer printed circuit board structure that combines signal processing and power supply circuits increases production costs and requires significant changes in circuit layout and area, leading to inefficiencies.
Innovation Solution
A board coupling structure where a signal processing circuit board and a power supply circuit board are formed as separate boards, laterally coupled using fasteners and electrical connectors, allowing them to operate as a single board while minimizing changes in circuit layout or area.

Engineering Contradiction Analysis
1Area of stationary object
If a multi-layer structure is used to reduce board area, then the area of circuit region is reduced, but the cost of the board increases
Solution Approach 1:
The invention divides the circuit board into multiple separate boards (first circuit board, second circuit board, third circuit board) that are coupled together. Specifically, the signal processing circuit and power supply circuit are separated onto different boards, allowing each board to be manufactured independently with fewer layers, thereby reducing overall manufacturing cost while maintaining compact area through lateral coupling
2Adaptability or versatility
If the area occupied by circuit or circuit arrangement is changed according to product specifications, then the product specifications are met, but the area change in the entire board or change in circuit layout occurs causing cost increase
Solution Approach 1:
By segmenting the circuit board into separate functional boards (signal processing board, power supply board, etc.), each board can be independently designed and sized according to specific product requirements without affecting the others. This modular approach allows flexible adaptation to different specifications while maintaining consistent manufacturing processes and avoiding costly layout changes across the entire system
Solution Approach 2:
The separate circuit boards are designed with standardized coupling interfaces and connection methods that can be universally applied across different product configurations. This allows the same board design to be used in multiple product variants by simply changing the number or arrangement of boards, rather than redesigning the entire circuit layout for each specification change

AI summary
Provided is a board coupling structure in which a power supply circuit board is formed as a separate board, more specifically, to a board coupling structure in which a signal processing circuit board for processing signals such as image signals, voice signals, and the like and a power supply circuit board are formed as different types of boards and the different types of boards are laterally coupled to each other. The board coupling structure includes a first circuit board, a second circuit board formed of a smaller number of layers than the number of layers of the first circuit board, and a fastening unit configured to laterally fasten a contact edge of the first circuit board to a contact edge of the second circuit board which are facing each other.
