Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate instruments are used to measure different optical characteristics, then measurement accuracy for each characteristic can be maintained, but device complexity and operational efficiency deteriorate due to requiring multiple separate devices
Solution Approach 1:
The patent combines multiple separate measurement instruments (spectrometer for spectrum, luminance meter for brightness, chromaticity meter for chromaticity, and viewing angle meter for viewing angle) into a single integrated device. The housing contains all four measurement components, allowing simultaneous or sequential measurement of all optical characteristics without requiring multiple separate instruments, thus resolving the contradiction between maintaining measurement accuracy and reducing device complexity
Solution Approach 2:
The integrated measurement device performs multiple functions within a single system. The housing simultaneously accommodates a spectrometer for spectral measurement, a luminance meter for brightness measurement, a chromaticity meter for chromaticity measurement, and a viewing angle meter for viewing angle measurement. This multi-functional design allows one device to replace four separate instruments, improving operational efficiency while maintaining the measurement capabilities of each individual instrument
2Measurement precision
If multiple separate instruments are used for testing, then each instrument can be optimized for its specific function, but productivity and measurement speed deteriorate due to sequential testing requirements
Solution Approach 1:
By merging four separate measurement instruments into one integrated device housed in a single housing, the system enables simultaneous or rapid sequential measurement of spectrum, brightness, chromaticity, and viewing angle. This eliminates the time required to transport and set up multiple separate instruments between measurements, significantly improving productivity and measurement speed while preserving the specialized measurement capabilities of each instrument type
3Productivity
If a single integrated device is used to measure all optical characteristics, then productivity and ease of operation improve, but device complexity increases due to integrating multiple components
Solution Approach 1:
The patent integrates four separate measurement instruments (spectrometer, luminance meter, chromaticity meter, and viewing angle meter) into a single housing with unified structural support. This consolidation allows operators to perform all optical characteristic measurements using one device, improving productivity and ease of operation by eliminating the need to handle multiple separate instruments, while the shared housing and mounting structures help manage the inherent complexity of integrating multiple components
