Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individual unidirectional secondary batteries are connected to a busbar through the side, then electrical connection is achieved, but the process requires a variety of components which are costly and laborious to mount and connect
Solution Approach 1:
The patent combines multiple terminal structures and the busbar into a single integrated assembly. The terminal structure assembly includes a terminal body with multiple extension terminals that extend in different directions, and the busbar is integrated within this assembly, eliminating the need for separate mounting of multiple components and simplifying the connection process.
Solution Approach 2:
The terminal structure assembly serves multiple functions simultaneously: it provides bidirectional terminal connections, integrates the busbar, and enables connection to multiple secondary batteries in different orientations. This multi-functional design replaces what would otherwise require separate components for each function.
2Adaptability or versatility
If positive and negative electrode terminals are arranged on one side or two opposing sides of prismatic secondary batteries, then the arrangement is determined by design specifications, but it is difficult to design the arrangement structure separately according to different design specifications
Solution Approach 1:
The terminal structure assembly provides dynamic adaptability through its bent configuration and multiple extension terminals that can extend in different directions. This allows the same basic assembly design to accommodate different terminal arrangement requirements by orienting the extension terminals appropriately, without requiring separate designs for different specifications.
Solution Approach 2:
The patent transitions from planar terminal arrangements to three-dimensional spatial arrangements. The terminal body is configured in a bent form with extension terminals extending in different directions and planes, enabling adaptation to various design specifications by utilizing spatial orientation rather than requiring separate two-dimensional layout designs.
3Adaptability or versatility
If terminal structure assembly is designed for unidirectional terminals, then the structure is simple, but it cannot convert to bidirectional arrangement without design changes
Solution Approach 1:
The terminal structure assembly employs asymmetric design with the terminal body bent at specific angles and extension terminals positioned at different locations and orientations. This asymmetric configuration enables bidirectional terminal arrangements while maintaining structural efficiency, as the asymmetric form factor is optimized for the dual-directional function rather than requiring symmetric designs for each direction separately.
