Battery Top Patch Inclined Hole Structure for Offcut Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing top patch design for energy-storage apparatuses is inefficient in production due to difficulties in removing offcuts, leading to increased machining time and potential damage during the cutting process, which affects the structural integrity and mounting reliability of the top patch.
Innovation Solution
A top patch design featuring inclined hole walls for through-holes and an explosion-proof valve through-hole, with a connecting through-hole that communicates between the pole through-holes, facilitates easier removal of offcuts and enhances structural integrity by preventing weak joint breakage and warpage, while also improving mounting stability and reducing material weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional top patch design with perpendicular hole walls is used, then machining is straightforward, but offcut removal is difficult and machining time increases
Solution Approach 1:
The hole walls are designed with asymmetric inclination angles relative to the connecting surface, creating non-perpendicular cutting surfaces that facilitate offcut removal. The inclined surfaces form acute angles with the connecting surface, allowing offcuts to be easily separated from the top patch after machining.
2Strength
If conventional top patch design is used, then structure is simple, but weak joints are prone to breakage and warpage occurs
Solution Approach 1:
The hole walls are configured with asymmetric inclination angles to create stronger joint structures. The inclined surfaces distribute stress more effectively and prevent warpage during machining and assembly, enhancing overall structural integrity without requiring complex additional components.
3Reliability
If conventional top patch design is used, then material usage is standard, but mounting stability is insufficient
Solution Approach 1:
The asymmetric inclined hole walls create optimal mounting surfaces that improve stability during installation. The inclination angles are designed to facilitate proper alignment and secure mounting of the top patch to the battery terminal, enhancing mounting reliability without adding complex mounting mechanisms.
