Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wiring modules for power storage element groups are difficult to deform and attach efficiently due to their rigid structure, which hinders independent connection of bus bars to electrode terminals, resulting in lower attachment efficiency.
Innovation Solution
A wiring module design featuring deformable sections, including first and second housing sections connected by warping sections and linking sections with twisting deformation portions, allowing for flexible warping and improved alignment with electrode surfaces, along with bus bars with multiple connection sections to prevent warping, and in-between routing sections for electric wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the linkage part is made of synthetic resin integrally with the accommodation parts and is linearly disposed, then the wiring module is less likely to be deformed with warping, but it is difficult to connect each electrode terminal to each bus bar independently and attachment efficiency is lowered
Solution Approach 1:
The housing sections are divided into multiple independent sections that can be deformed independently. Each accommodation part can approach the electrode surface individually while others remain spaced away, enabling independent connection of bus bars to electrode terminals without requiring the entire structure to move together.
Solution Approach 2:
The patent introduces deformable linkage parts that can change the distance between accommodation parts dynamically. This allows the wiring module to adapt its configuration during attachment, transitioning from a spaced-apart state to a connected state as bus bars are connected to electrode terminals, thereby improving attachment efficiency.
2Stability of the object's composition
If the wiring module is forced to stay in the position spaced away from the electrode surfaces as a whole, then warping is prevented, but bus bars cannot be connected to electrode terminals independently
Solution Approach 1:
The housing is segmented into multiple independently deformable accommodation parts. Each part can move toward or away from the electrode surface independently, allowing individual bus bars to be connected to electrode terminals while other parts remain in their original positions, thus maintaining overall structural stability while enabling independent connections.
Solution Approach 2:
Different regions of the housing have different deformation characteristics. The linkage parts connecting accommodation parts have specific deformability that allows local adjustment without affecting the entire structure. This enables local connection operations while maintaining global structural integrity.
3Strength
If bus bars are attached to the power storage element group at the same time, then structural integrity is maintained, but performing efficiency of attaching the wiring module is lowered
Solution Approach 1:
The wiring module is designed to be pre-assembled with all bus bars and accommodation parts in place before attachment to the power storage element group. The deformable linkage parts are pre-configured to allow sequential connection, enabling the module to be attached as a complete unit while still allowing individual bus bar connections to be made in sequence, thereby improving attachment efficiency without compromising structural integrity.

AI summary
A wiring module includes a first housing section row, a second housing section row, and linking sections. The first housing section row includes first housing sections that are arranged in an arrangement direction and include connection bus bars therein, respectively. The second housing section row includes second housing sections that are arranged in the arrangement direction and include the connection bus bars and output bus bars therein, respectively, and is disposed away from the first housing section row with respect to a crossing direction that crosses the arrangement direction. The linking sections are disposed between the first and second housing section rows and link the first and second housing section rows. The first housing sections are connected by a first warping section that can be deformed with warping and the second housing sections are connected by a second warping section that can be deformed with warping.
