Battery Wiring Module Cover With Dual Lids for Safe Terminal Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery wiring modules expose electrode terminals during vehicle maintenance, posing safety risks and complicating workability during vehicle manufacture due to conflicting needs for protection and wide exposure.
Innovation Solution
A battery wiring module with a cover portion featuring a large lid portion and a small lid portion, rotatably attached via hinges, allowing wide exposure during manufacture and safe coverage during maintenance, using a retainer to stabilize the large lid portion in an open position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electrode terminals are exposed without being covered by the cover portion, then the workability during vehicle manufacture is improved, but the safety during vehicle maintenance deteriorates due to the risk of operator contact with live terminals
Solution Approach 1:
The cover portion is designed to be movable between a closed state (covering the electrode terminals for safety during maintenance) and an open state (exposing the electrode terminals for workability during manufacture). This dynamic configuration allows the same structure to serve different functional requirements in different operational phases.
Solution Approach 2:
The cover portion is divided into a large lid portion and a small lid portion that can be independently opened or closed. This segmentation allows selective exposure of different regions of the electrode terminals, providing flexibility in balancing safety and workability requirements during different operations.
2Object-affected harmful factors
If the electrode terminals are covered by the cover portion, then the safety during vehicle maintenance is improved, but the workability during vehicle manufacture deteriorates due to limited exposure for connections
Solution Approach 1:
The cover portion transitions from a static covered state to a dynamically openable state, allowing the electrode terminals to be exposed when needed for manufacturing operations while remaining covered for safety during maintenance operations.
Solution Approach 2:
The segmented lid structure allows the cover to be partially opened (small lid portion) or fully opened (large lid portion) depending on the specific manufacturing task, providing optimized access to electrode terminals while maintaining safety protection when not in use.
3Device complexity
If a fixed cover structure is used, then the safety protection is simplified, but the adaptability to different operational requirements (maintenance vs. manufacture) deteriorates
Solution Approach 1:
The cover structure incorporates movable lid portions with hinge connections, transforming a simple fixed cover into an adaptable dynamic structure that can adjust its coverage level based on operational requirements without significantly increasing overall system complexity.
Solution Approach 2:
The movable cover structure serves multiple functions: it provides safety protection during maintenance, enables workability during manufacture, and allows selective exposure of different terminal regions. This multi-functionality is achieved through the hinge-connected lid portions that can be positioned in different states.
