Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional power meter is interjected to measure power consumption, then measurement precision is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent combines the power measurement function with the existing electrical components of the display assembly. The current sensor is integrated into the power distribution system, and the processor uses existing voltage measurements combined with current sensing to calculate power consumption. This merging eliminates the need for separate traditional power meters while maintaining measurement capability.
Solution Approach 2:
The patent introduces a current sensor as an intermediary element that works in conjunction with the existing power supply system. Rather than using a complete traditional power meter, the current sensor serves as a simplified intermediary that provides the necessary measurement data when combined with voltage information from the power distribution system.
2Measurement precision
If a traditional power meter is installed, then power consumption monitoring is improved, but ease of manufacture deteriorates
Solution Approach 1:
The measurement system is merged into the manufacturing process of the display assembly itself. The current sensor and processing logic are integrated components that are manufactured and assembled together with the display unit, eliminating the need for separate installation of traditional power meters and simplifying the overall manufacturing process.
Solution Approach 2:
The display assembly is designed to be self-measuring through integrated sensors and processing. The system automatically monitors its own power consumption using the current sensor and voltage measurements from its existing power distribution system, eliminating the need for external measurement devices and complex installation procedures.
3Measurement precision
If a power meter is interjected, then power consumption data is obtained, but aesthetic appearance deteriorates
Solution Approach 1:
The measurement functionality is merged into the internal structure of the display assembly, with sensors and processing components integrated into the housing and electrical system. This integration eliminates the need for external power meter devices that would compromise the aesthetic appearance of the display.
4Measurement precision
If a power meter is installed, then power consumption is measured, but installation time and labor cost increase
Solution Approach 1:
The measurement system is combined with the standard assembly process, allowing measurement components to be installed simultaneously with other assembly components during normal manufacturing. This eliminates the need for separate installation of traditional power meters and reduces overall installation time and labor requirements.
