Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stud and nut connection is used to electrically connect positive and negative poles, then electrical connection is achieved, but assembly complexity increases and installation efficiency decreases
Solution Approach 1:
The patent extracts and eliminates the stud and nut components from the battery assembly. Instead of using separate fastening components, the PCB board holder directly integrates the electrical connection function through through-holes that receive and secure the positive and negative terminals, thereby simplifying the assembly structure while maintaining reliable electrical connection.
Solution Approach 2:
The patent merges the functions of electrical connection and structural support into a single integrated PCB board holder. The holder combines the PCB mounting function with the terminal connection function through its through-holes, eliminating the need for separate stud and nut components and reducing overall assembly complexity.
2Reliability
If a stud and nut connection is used to electrically connect positive and negative poles, then electrical connection is achieved, but production cost increases
Solution Approach 1:
The patent removes the stud and nut components from the assembly, eliminating the need to source, inventory, and assemble these separate fastening parts. This reduction in component count directly lowers material costs and simplifies the manufacturing process, making production more cost-effective while maintaining reliable electrical connections through the integrated PCB board holder design.
3Ease of operation
If traditional charging manner is used, then charging function is provided, but adaptability to different occasions is limited
Solution Approach 1:
The patent incorporates a charging port directly into the PCB board, enabling the battery to support both traditional charging methods and direct integration into electronic devices. This multi-functional design allows the battery to adapt to different charging occasions and applications, enhancing its versatility while maintaining ease of operation.
