Battery Partition Board Guide Pins Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the assembly of battery packs, partition boards between secondary batteries tend to incline when slid into position, leading to uneven clearance and potential misalignment, which complicates the arrangement and restraint of electrical storage elements.
Innovation Solution
The partition board design incorporates a guide portion and two pins that protrude in the predetermined direction, allowing for precise positioning and alignment, with the second pin located differently to prevent inclination and ensure uniform clearance between adjacent boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If partition boards are slid into position during assembly, then the partition boards can be installed between electrical storage elements, but the partition boards incline with respect to the predetermined direction causing uneven clearance
Solution Approach 1:
The guide portions are pre-formed on the partition boards before assembly, and the protrusions on electrical storage elements are designed to engage with these guide portions during insertion. This preliminary preparation of guiding structures ensures that as the partition boards are slid into position, they are automatically guided to remain parallel to the predetermined direction, preventing inclination and ensuring uniform clearance without requiring complex adjustment mechanisms during assembly
Solution Approach 2:
The guide portions act as intermediary structures between the partition boards and electrical storage elements. These guide portions, with their specific geometry including tapered sections, mediate the interaction during assembly by providing a controlled interface that guides the partition boards into the correct position and orientation, preventing direct uncontrolled contact that would cause inclination
2Reliability
If multiple partition boards are arranged in the predetermined direction, then they can separate electrical storage elements, but maintaining uniform clearance between adjacent boards becomes difficult
Solution Approach 1:
The guiding function is segmented and distributed to each individual partition board through its own guide portions. Each partition board independently engages with the protrusions on adjacent electrical storage elements via its guide portions, ensuring that each board maintains uniform clearance with its neighbors independently. This segmentation of the guiding function to individual components ensures consistent clearance uniformity across the entire series of partition boards without requiring complex interconnections

AI summary
A partition board that is arranged between two electrical storage elements that are arranged adjacent to each other in a predetermined direction (X direction) includes a guide portion, a first pin and a second pin. The guide portion is used to cause the partition board to move in the predetermined direction when each electrical storage element is arranged onto the partition board. The first pin protrudes in the predetermined direction, and is used to position the partition board in the predetermined direction. The second pin is provided at a location different in a top to bottom direction of the partition board from a location at which the first pin is provided, and protrudes in the same direction as the direction in which the first pin protrudes.
