Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery assembly mounting structures in vehicles face challenges such as long charging times, difficulty in replacing batteries, misassembly during assembly, and the need for separate handling of fastening bolts, which complicates maintenance and reuse.
Innovation Solution
A battery assembly mounting structure that includes a through pipe with a swappable assembly and a fastening bolt system, where the fastening bolt remains assembled with the battery assembly even when detached, allowing reuse and easy replacement, and features a guiding mechanism to prevent misassembly and facilitate smooth assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fastening bolt is completely detached from the battery assembly during battery replacement, then the battery assembly can be easily removed, but the fastening bolt must be handled separately and cannot be reused
Solution Approach 1:
The fastening bolt is merged with the battery assembly through the retaining member, forming an integrated assembly. When the battery assembly is removed, the fastening bolt remains attached to the battery assembly via the retaining member, eliminating the need for separate handling and enabling direct reuse in subsequent battery replacements.
Solution Approach 2:
The fastening system is segmented into multiple components: the fastening bolt, the retaining member, and the battery assembly. The retaining member acts as an intermediary that holds the fastening bolt separately from the vehicle body while maintaining association with the battery assembly, allowing the bolt to be reused without complete detachment.
2Reliability
If the fastening bolt is tightly fixed to the vehicle body, then the battery assembly is securely mounted, but the fastening bolt cannot be easily replaced when damaged
Solution Approach 1:
The fastening system transitions from a static fixed state to a dynamic removable state through the retaining member. The retaining member allows the fastening bolt to be easily detached from the vehicle body when needed, while maintaining secure mounting during normal operation, thus enabling quick replacement when damaged.
Solution Approach 2:
The retaining member serves as an intermediary component between the fastening bolt and the vehicle body. It provides a removable connection point that allows the fastening bolt to be easily detached and replaced, while still maintaining reliable mounting when assembled, solving both security and replaceability requirements.
3Ease of operation
If the fastening bolt is completely removed during assembly, then assembly flexibility is improved, but misassembly may occur due to lack of guidance
Solution Approach 1:
The retaining member is pre-assembled with the fastening bolt before installation on the vehicle body. This preliminary assembly ensures proper alignment and positioning of the fastening bolt relative to the battery assembly, preventing misassembly while maintaining the flexibility to remove and replace components as needed.
