Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power supply configuration with multiple conductive components and bonding wires is used, then electrical connection is achieved, but assembly complexity increases and automatic assembly becomes difficult
Solution Approach 1:
The patent merges multiple conductive components and bonding wires into a single integrated conductive structure that directly connects the battery terminals to the electrode assembly. This consolidation eliminates the need for separate bonding wires and multiple conductive components, thereby reducing assembly complexity while maintaining reliable electrical connection.
Solution Approach 2:
The power supply is divided into modular components: a battery assembly with integrated conductive structure, an electrode assembly, and a housing. This segmentation allows each module to be manufactured and tested independently, then assembled together, which simplifies the overall assembly process and enables automatic assembly while ensuring reliable electrical connections within each module.
2Reliability
If multiple conductive components and bonding wires are used, then electrical connection is established, but assembly mistakes like short circuits increase
Solution Approach 1:
By integrating multiple conductive components into a single pre-assembled conductive structure, the patent eliminates the need for precise positioning and connection of multiple separate wires during assembly. This merging reduces the risk of assembly mistakes such as short circuits while ensuring reliable electrical connection between battery terminals and electrode assembly.
Solution Approach 2:
The conductive structure is pre-assembled and configured with correct electrical connections before integration into the complete power supply. This preliminary action ensures that electrical connections are established accurately in advance, preventing assembly mistakes like short circuits during final assembly while maintaining reliable electrical connectivity.
3Ease of manufacture
If conventional assembly methods are used, then power supply is assembled, but automatic assembly is hard to implement
Solution Approach 1:
The power supply is segmented into standardized modules (battery assembly with integrated conductive structure, electrode assembly, housing) that can be independently manufactured and then automatically assembled using robotic systems. This modular segmentation enables automatic assembly by allowing precise positioning and connection of discrete modules without complex manual wiring operations.
Solution Approach 2:
By merging multiple conductive components into a single integrated structure, the patent eliminates complex wiring operations that would require manual dexterity and precision. This consolidation creates a simpler assembly process that can be easily automated, as the integrated conductive structure can be positioned and connected as a single unit rather than requiring separate wire routing and connection operations.
