A battery connection module design featuring a single layer wiring flexible circuit board with rounding traces and rounded traces that extend onto lateral extension support arms or bridge-type extension pieces, allowing for non-intersecting wiring configurations and reducing manufacturing costs by eliminating the need for multi-layer boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single layer flexible circuit board is used to reduce cost, then manufacturing cost is reduced, but wiring intersection cannot be realized in compact spaces
Solution Approach 1:
The patent applies dimensionality change by extending traces from the front surface to the rear surface of the flexible circuit board through lateral extension support arms. This allows wiring to utilize both surfaces of the single-layer board, effectively creating a multi-dimensional wiring solution that enables trace intersection without requiring multiple layers, thus reducing manufacturing cost while maintaining wiring complexity management.
2Device complexity
If a flexible circuit board is cut and folded to make wirings intersected, then wiring intersection is achieved, but structure strength is significantly lowered
Solution Approach 1:
The patent segments the flexible circuit board into functional regions: front surface for connector connecting points, rear surface for busbar connections, and lateral extension support arms for trace extension. This segmentation allows wiring intersection to be achieved through the extended lateral arms rather than cutting and folding the main board structure, preserving overall structural strength while enabling complex wiring arrangements.
3Area of stationary object
If connector connecting points are arranged densely or in rows, then space utilization is improved, but wiring lines must be intersected
Solution Approach 1:
By extending traces onto the rear surface of the flexible circuit board through lateral extension support arms, the patent enables wiring to utilize the third dimension (depth/thickness) of the board. This allows densely arranged connector connecting points on the front surface to connect to busbars on the rear surface without requiring complex intersections on the same plane, thus maintaining space utilization while simplifying wiring arrangement.
