Angled Battery Connecting Member for Stress-Stable Casing Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery technologies face challenges in ensuring stable and efficient electrical connections between cells and battery casings, particularly in electric vehicles, where stress concentrations can lead to connection instability and overcurrent issues.
Innovation Solution
A battery connecting member with a first connecting portion, a second connecting portion, and a buffering portion is used, where the second connecting portion is inclined relative to the first, increasing the connection area and stability, and the buffering portion helps distribute stress, preventing concentration during installation and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a traditional battery connecting member with perpendicular connecting portions is used, then the manufacturing process is simple, but the connection area is small and stress concentrates at the connection points
Solution Approach 1:
The patent applies asymmetry by designing the second connecting portion to be inclined relative to the first connecting portion, rather than perpendicular. This asymmetric angular configuration increases the connection area between the battery casing and the connecting member, distributing stress more effectively while maintaining structural integrity.
Solution Approach 2:
The patent introduces an angular dimension by inclining the second connecting portion at a specific angle relative to the first connecting portion. This dimensional change from a simple perpendicular arrangement to an inclined configuration expands the connection interface area and improves stress distribution without significantly complicating the overall structure.
2Reliability
If connecting portions are directly connected without buffering, then the structure is simple, but stress concentrates during installation and transportation causing connection instability
Solution Approach 1:
The patent introduces a buffering portion as an intermediary element between the first and second connecting portions. This buffering portion acts as a stress-absorbing mediator that prevents direct stress transmission during installation and transportation, thereby improving connection stability and reliability without adding excessive structural complexity.
Solution Approach 2:
The buffering portion provides beforehand cushioning by being pre-designed to absorb and distribute stresses that will occur during installation and transportation. This preventive measure ensures that stress concentrations are mitigated before they can cause connection instability or damage.
3Strength
If the connecting member has a rigid structure, then manufacturing is easy, but it cannot accommodate stress during installation and transportation
Solution Approach 1:
The patent applies parameter changes by modifying the geometric parameters of the connecting member, specifically the angle between connecting portions and the inclusion of a buffering portion. These parameter changes enable the structure to accommodate stress during installation and transportation while maintaining ease of manufacture through standard fabrication processes.
