Solution Overview
Problem
Existing battery connectors have exposed connection terminals with sharp edges and electrical issues, posing risks of user injury, object damage, electric shock, and signal interference during charging.
Innovation Solution
A battery connector design featuring a terminal holder with connecting terminals, guiding columns, and covers, where the terminals are hidden when disconnected and exposed during connection, using elastic members and guiding columns to ensure safe and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connection terminals are exposed for easy connection, then the ease of operation is improved, but the safety and reliability deteriorate due to sharp edges and electrical hazards
Solution Approach 1:
The connection terminals are nested within the cover body, which encloses them when the connector is not in use. This nesting structure allows the terminals to be easily accessible during connection while being protected and hidden during storage or transport, resolving the contradiction between ease of operation and safety.
Solution Approach 2:
The connector transitions between two dynamic states: in the disconnected state, the cover body shields the terminals for safety; in the connected state, the terminals are exposed for connection. This dynamic state change allows the system to optimize for safety when not in use and for ease of operation when needed.
2Ease of operation
If the connection terminals are exposed for direct access, then the ease of operation is improved, but the object-generated harmful factors worsen due to sharp edges causing injury or damage
Solution Approach 1:
The cover body acts as a protective enclosure that nests the connection terminals within its cavity. This structure eliminates exposed sharp edges during non-operational states while maintaining easy access during connection, thereby reducing object-generated harmful factors without compromising ease of operation.
Solution Approach 2:
The harmful sharp edges are effectively extracted from the operational interface by enclosing them within the cover body. The connection terminals remain functional when needed but are separated from the external environment when not in use, removing the harmful aspect while preserving the useful function.
3Ease of operation
If the connection terminals are exposed for alignment, then the ease of operation is improved, but the object-affected harmful factors worsen due to electric shock and signal interference
Solution Approach 1:
The cover body provides a nested protective structure that encloses the connection terminals, shielding them from external electrical hazards when not in use. The guiding columns extend through the cover to enable alignment functionality while the terminals themselves remain protected within the cover cavity, resolving the contradiction between alignment capability and electrical hazard protection.
Solution Approach 2:
The cover body acts as an intermediary protective barrier between the connection terminals and the external environment. It allows alignment to occur through the guiding columns while preventing direct exposure of the terminals to electrical hazards, thus mediating between operational requirements and safety protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents user injury and electric shock by hiding sharp edges, enhances connection security, and reduces signal interference by ensuring proper alignment and attachment of the connector.
Implementation Method 1
The elastic member is arranged between the first cover and the second cover. In a disconnected state, the connecting terminals are received within the second cover

AI summary
A battery connector having a terminal holder, a connecting terminal, a guiding column, a first cover, a second cover, and an elastic member is provided. The connecting terminal is arranged on the terminal holder. The guiding columns is arranged on the terminal holder and formed on two sides of the connecting terminals. The first cover and the second cover accommodate the terminal holder. The second cover has a terminal hole for the connecting terminal outstretching or retracting therein. The elastic member is arranged between the first cover and the second cover. In a disconnected state, the connecting terminal is received within the second cover, at least a portion of the guiding column is exposed outside the second cover. In a connected state, the connecting terminals move along an axial direction of the guiding column to be exposed outside the second cover.
