Battery Module Frame Guidelines for Precise Insulating Sheet Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to effectively and quickly attach an insulating sheet to a frame surrounding secondary batteries within a battery module, particularly due to the high electrical conductivity of materials like aluminum, which requires enhanced insulation to prevent interference and ensure accurate positioning.
Innovation Solution
A frame with a first guideline for guiding the attachment of an insulating sheet and a second guideline of a different length and height, allowing the sheet to be securely positioned and attached along both axes, ensuring precise placement and improved insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an insulating sheet is attached to a frame made of high electrical conductivity material, then insulation performance is improved, but attachment precision and positioning accuracy deteriorate due to lack of guidance
Solution Approach 1:
Guidelines are pre-provided on the frame surface before insulating sheet attachment. These guidelines indicate the exact attachment position and orientation, allowing workers to quickly and accurately position the insulating sheet without requiring complex measurement or alignment procedures during the attachment process.
Solution Approach 2:
The guidelines act as an intermediary element between the frame and the insulating sheet. They provide visual or physical guidance that mediates the positioning process, ensuring the insulating sheet is attached at the correct location and orientation relative to the frame's coordinate system.
2Productivity
If traditional attachment methods are used without guidelines, then device complexity is reduced, but attachment time and productivity deteriorate
Solution Approach 1:
The guidelines are incorporated into the frame structure during manufacturing, so they are already in place before the insulating sheet attachment process begins. This preliminary preparation eliminates the need for complex alignment procedures during assembly, significantly reducing attachment time and improving productivity.
Solution Approach 2:
The guidance function is segmented from the main structural function of the frame. The guidelines are distinct features on the frame surface that provide positioning information without compromising the frame's primary structural role, thus adding minimal complexity while delivering significant productivity benefits.
