Battery Unit Internal Plate Merging Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery pack attachment methods to housings are inefficient due to the need for separate brackets and double-sided tapes, which can lead to misalignment and increased operational complexity.
Innovation Solution
A battery unit design featuring a reinforced internal plate with screws for attaching the battery pack to the housing, eliminating the need for separate brackets and enhancing attachment efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery pack is fixed to the bottom wall part of the housing by using a double-sided tape and a bracket, then the battery pack can be attached to the housing, but the attachment operation becomes inefficient and complex due to misalignment issues and the need for multiple components
Solution Approach 1:
The patent combines the bracket and mounting plate into a single integrated internal plate structure. The internal plate is directly attached to the bottom wall part of the housing and provides both the support function of a bracket and the mounting surface function of a plate, eliminating the need for separate components and reducing alignment issues.
Solution Approach 2:
The internal plate serves multiple functions: it acts as a structural support element attached to the housing bottom wall, provides a mounting surface for the battery pack, and includes through holes for fastener attachment. This multi-functional design replaces what would traditionally require multiple separate components.
2Reliability
If a bracket is used to hold the battery pack from opposite sides, then the battery pack can be secured to the housing, but the housing dimension constraints make it difficult to dispose the bracket properly
Solution Approach 1:
The bracket and mounting plate functions are merged into the internal plate, which is custom-formed to fit the housing interior. The internal plate includes integrated through holes positioned to receive fasteners, combining the support and mounting functions into a single component that is easier to manufacture and assemble within housing dimension constraints.
3Manufacturing precision
If the battery pack is positioned shifted from the predetermined position during attachment, then misalignment occurs, but re-attachment is required which reduces operational efficiency
Solution Approach 1:
The internal plate is pre-attached to the bottom wall part of the housing with through holes positioned at predetermined locations. This preliminary positioning provides alignment guides for the battery pack, ensuring accurate placement before final fastening and eliminating the need for re-attachment due to misalignment.
