Solution Overview
Problem
In electric vehicles, the vibration of battery containers affects other structures of the battery pack, such as temperature regulating plates and base plates, leading to potential damage and instability.
Innovation Solution
A battery container design featuring adhesive receiving grooves on beams and spacers to securely connect batteries, reducing the active force on other structures and enhancing stability by using connection adhesives to attach batteries to beams and spacers within the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If batteries are installed in a battery container without adhesive receiving grooves, then the installation process is simple, but the connection strength between batteries and beams is insufficient, causing vibration to affect other structures
Solution Approach 1:
Adhesive receiving grooves are pre-formed on the beams during manufacturing, allowing connection adhesive to be properly positioned and applied before battery installation. This preliminary preparation ensures strong connection without requiring complex assembly procedures, resolving the contradiction between connection strength and installation simplicity.
Solution Approach 2:
Connection adhesive serves as an intermediary substance between the beam and battery, filling the adhesive receiving groove to create a strong bonding interface. This mediator enables reliable mechanical connection while maintaining manufacturing simplicity, addressing the contradiction between connection strength and structural complexity.
2Reliability
If batteries are directly placed in the battery container without adhesive connection, then the manufacturing process is simple, but vibration during vehicle operation affects temperature regulating plates and base plates
Solution Approach 1:
The adhesive receiving grooves are pre-formed on beams and spacers during manufacturing, establishing a reliable connection structure in advance. This preliminary action ensures that when batteries are installed, they will be securely connected and isolated from vibration, improving reliability without significantly complicating the manufacturing process.
Solution Approach 2:
Connection adhesive acts as an intermediary that bonds batteries to beams and spacers, creating a stable connection that isolates other structures from vibration. This mediator provides reliable mechanical coupling while maintaining ease of manufacture through simple adhesive application procedures.
3Force
If traditional mounting methods are used without adhesive receiving grooves, then the device structure is simple, but the active force from battery weight and vibration damages other structures
Solution Approach 1:
The battery container structure is segmented into beams and spacers with integrated adhesive receiving grooves. This segmentation creates multiple discrete connection points that distribute the active force from battery weight and vibration across different locations, reducing stress concentration and preventing damage to temperature regulating plates and base plates, while maintaining relatively simple structural design.
