Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional connection methods for energy storage devices are used, then electrical connection is achieved, but device complexity increases and compactness is reduced
Solution Approach 1:
The patent combines the electrical connection and mechanical retention functions into a single integrated connector design. The connector simultaneously establishes electrical contact and provides mechanical securing through the shaft-like recess structure, eliminating the need for separate connection components and reducing overall device complexity while maintaining reliable connection.
Solution Approach 2:
The connector is designed to perform multiple functions: electrical conduction, mechanical retention, and alignment guidance. The shaft-like recess structure serves as both the electrical contact interface and the mechanical securing mechanism, allowing a single component to fulfill multiple connection requirements without increasing complexity.
2Device complexity
If conventional connection methods are used, then electrical connection is established, but the design becomes less compact
Solution Approach 1:
The connector is nested within the shaft-like recess of the housing body, with the energy storage device inserted into this recess. This nested arrangement allows the connector to be housed within the existing structure without adding external protrusions, maintaining compact design while providing easy access for insertion and removal operations.
3Reliability
If a secure connection is implemented, then connection stability improves, but device complexity increases
Solution Approach 1:
The shaft-like recess has an asymmetric cross-sectional geometry that does not match the external geometry of the energy storage device. This asymmetric fit provides inherent mechanical retention and positioning, securing the connection through geometric interlocking rather than additional fastening mechanisms, thereby maintaining connection security while minimizing structural complexity.
