Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery mounting structures in electric and hybrid vehicles require separate handling of fastening bolts during repeated mounting and removal, leading to inefficiencies and potential mis-fastening, and do not allow for easy replacement of damaged bolts.
Innovation Solution
A battery mounting structure that includes a mounting bush with a sleeve assembly to elastically support the fastening bolt, allowing it to remain coupled to the battery even when separated from the vehicle body, ensuring reusable bolts and guided fastening angles for improved assembly and disassembly workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the battery is separated from the vehicle body for replacement, then the charging time disadvantage is overcome, but the fastening bolts must be handled separately leading to inefficiency and potential mis-fastening
Solution Approach 1:
The fastening bolt is merged with the battery assembly by having it penetrate through the mounting bush and be elastically supported within the mounting bush. This integration ensures the fastening bolt remains coupled to the battery even when separated from the vehicle body, eliminating the need for separate handling of fastening bolts during battery replacement operations.
Solution Approach 2:
The mounting bush acts as an intermediary component that elastically supports the fastening bolt. This intermediary structure allows the fastening bolt to be maintained in a coupled state with the battery while enabling easy replacement of the entire battery assembly, thus resolving the contradiction between replacement efficiency and operational ease.
2Device complexity
If conventional fastening bolts are used, then the structure is simple, but assembly tolerance cannot be readily absorbed and fastening angle errors occur
Solution Approach 1:
The mounting bush is designed with elastic properties, transforming the static fastening structure into a dynamic one. The elastic mounting bush can deform to absorb assembly tolerance variations and guide the fastening bolt to the correct fastening angle, thereby improving manufacturing precision without significantly increasing device complexity.
3Productivity
If the fastening bolt is completely separated from the battery during removal, then the battery can be detached, but the fastening bolt cannot be reused and must be reinstalled
Solution Approach 1:
The fastening bolt is merged with the battery assembly through the mounting bush structure. The elastic mounting bush maintains coupling between the fastening bolt and battery, ensuring the fastening bolt remains attached to the battery during removal and can be reused in subsequent assembly operations, thereby improving both productivity and reliability.
4Device complexity
If no guidance mechanism is provided for the fastening bolt, then the structure is simpler, but fastening angle errors and mis-fastening occur
Solution Approach 1:
The mounting bush serves as a guidance intermediary that the fastening bolt penetrates through. This intermediary structure provides the necessary guidance for the fastening bolt, ensuring accurate fastening angle and preventing mis-fastening, while adding only moderate complexity to the overall structure.
