Terminal Protection Cover for Battery Module Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery modules are prone to short circuits and operator electric shock during transportation due to open connection ports, which are not adequately protected in existing designs.
Innovation Solution
A terminal protection cover with a base portion and side wall featuring strategically placed openings and snap components that can be removed to expose the output terminal, providing insulation and secure snap-fit attachment to prevent accidents while allowing for easy connection between modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connection port is left open to facilitate module connection, then the ease of operation is improved, but the reliability deteriorates due to risk of short circuit and electric shock during transportation
Solution Approach 1:
The connection port is segmented into two functional states: a closed protected state during transportation and an open accessible state during connection. The cover portion can be removed to expose the connection terminal, allowing the system to switch between safety and operability modes.
Solution Approach 2:
The connection port is pre-protected by the cover portion before connection operations are needed. This preliminary protective action prevents short circuits and electric shocks during transportation, and the cover is designed to be easily removed when connection is required.
2Reliability
If the connection port is covered to prevent short circuit and electric shock, then the reliability is improved, but the ease of operation deteriorates due to reduced accessibility
Solution Approach 1:
The cover portion transitions from a fixed closed state to a removable open state. This dynamic design allows the connection terminal to be accessible when needed while maintaining protection during transportation, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The cover portion is designed as a separate extractable component that can be removed to expose the connection terminal. This extraction mechanism maintains the protective function during transportation while enabling easy access during connection operations.
3Reliability
If a protective cover is added to the connection port, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The cover portion is designed as a simple shell structure that provides protection without adding significant complexity. The base portion with its opening and the cover portion form a minimalistic protective assembly that maintains structural simplicity while ensuring safety.
