Battery Pack Protruding Connector for Secure Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs for electric bikes and motor cycles face challenges in efficient electrical connection and disconnection with external devices, requiring dedicated wires and complex configurations, which complicates user convenience and increases theft risks.
Innovation Solution
A battery pack design featuring a protruding connector with a bent shape that extends along the upper surface of the battery pack, allowing for easy connection to external devices without additional wires, and a connection recess on the front cover for serial or parallel interconnection, along with a coupling member that functions as a key box for security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated wires and complex configurations are used for electrical connection, then reliable electrical connection is achieved, but user convenience deteriorates and theft risk increases
Solution Approach 1:
The patent merges the electrical connection function with the mechanical connector structure. The connector integrates contact terminals that directly establish electrical connection when mechanically coupled, eliminating the need for separate dedicated wires. This combination maintains reliable electrical connection while significantly improving connection convenience and reducing theft risk.
Solution Approach 2:
The connector is designed to serve multiple functions: mechanical connection, electrical connection, and security protection. The same connector structure that provides mechanical coupling also establishes electrical contact and prevents theft through its integrated design, reducing the need for additional components and simplifying the overall system.
2Reliability
If multiple components and dedicated wires are used, then electrical connection reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions (mechanical connection, electrical connection, and security) into a single integrated connector assembly. This merger eliminates the need for separate dedicated wires and multiple components, reducing device complexity while maintaining reliable electrical connection through the integrated contact terminals.
3Reliability
If traditional wire-based connection is used, then electrical connection is established, but theft risk and disconnection difficulty increase
Solution Approach 1:
The connector integrates mechanical coupling and electrical connection into a single unified structure. The same components that establish mechanical connection also provide electrical contact through integrated terminals, eliminating vulnerable separate wire connections that could be easily stolen or disconnected, thereby reducing theft risk while maintaining reliable electrical connection.
