Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional battery capacity meter design is used, then the device can measure power output, but the number of parts is large and the structure is complex
Solution Approach 1:
The patent merges multiple functional components (circuit board, display component, controller, buzzer) into a single integrated circuit board assembly. The circuit board carries both the display component and controller, and the buzzer is integrated onto the same circuit board, eliminating the need for separate mounting structures and reducing the overall number of parts while improving maintainability.
2Adaptability or versatility
If multiple separate components are used in battery capacity meter, then each component can be independently designed, but the degree of integration is low
Solution Approach 1:
Multiple functional components are merged onto a single circuit board. The circuit board serves as a common platform for mounting the display component, controller, and buzzer, with electrical connections established through standard PCB techniques. This achieves high integration while maintaining design flexibility through modular component selection.
Solution Approach 2:
The circuit board is designed as a multi-functional platform that simultaneously supports display output, control logic, and alarm functions. This universal platform approach allows different components to share common mounting and electrical connection infrastructure, reducing overall system complexity.
