Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single surface characteristic measurement device is used to measure both gloss and reflection characteristics, then device complexity is reduced, but the ability to appropriately set measurement target areas is compromised due to fixed measurement diameter
Solution Approach 1:
The patent implements a movable aperture diaphragm that can be positioned at different locations along the optical path to dynamically change the measurement diameter. This allows a single device to adapt its measurement area size based on the sample characteristics, resolving the contradiction between device simplicity and measurement adaptability.
Solution Approach 2:
The patent creates a universal measurement device that can perform both gloss and reflection characteristic measurements with a single instrument. By incorporating a variable aperture mechanism, the device achieves multi-functionality in terms of both measurement types and measurement area sizes, eliminating the need for multiple separate devices.
2Adaptability or versatility
If separate devices are used for gloss and reflection characteristic measurements, then measurement target area can be appropriately set for each measurement type, but device complexity and operational complexity increase
Solution Approach 1:
The patent merges gloss measurement and reflection characteristic measurement functions into a single integrated device. By combining multiple measurement capabilities and a variable aperture system in one instrument, it reduces the number of separate devices needed while maintaining the ability to appropriately set measurement areas for different measurement types.
3Measurement precision
If measurement diameter is increased for non-uniform surfaces, then measurement accuracy improves, but the device cannot adapt to small or curved samples requiring smaller measurement diameters
Solution Approach 1:
The patent employs a dynamically adjustable aperture diaphragm that can change the measurement diameter size based on sample characteristics. For non-uniform surfaces, a larger diameter can be selected to improve measurement accuracy, while for small or curved samples, a smaller diameter can be used to match the sample size, thus resolving the contradiction between measurement precision and sample adaptability.
4Adaptability or versatility
If measurement diameter is decreased for small or curved samples, then device adaptability to sample size improves, but measurement accuracy may decrease for non-uniform surfaces
Solution Approach 1:
The variable aperture diaphragm system allows dynamic selection of measurement diameter based on sample characteristics. When measuring small or curved samples, a smaller diameter is selected to match the sample size, and when measuring non-uniform surfaces, a larger diameter is selected to capture sufficient surface area for accurate measurement, thus resolving the contradiction between sample adaptability and measurement accuracy.

AI summary
The present invention enables both gloss measurement and reflectance characteristic measurement by means of a single surface characteristic measurement device, and appropriately sets the measurement region for the gloss measurement and the measurement region for the reflectance characteristic measurement. The gloss measurement mechanism and a colorimetry mechanism are integrated in a gloss meter/colorimeter. The gloss measurement mechanism illuminates an illumination subject surface by means of illumination light, receives the reflected light generated by means of a regular reflection of the illumination light by the illumination subject surface, and outputs the result of measuring the reflected light. The size of the measurement region for the gloss measurement can be altered. The colorimetry mechanism illuminates the illumination subject surface by means of ring-shaped illumination light, receives the reflected light generated by means of the ring-shaped illumination light being reflected by the illumina - tion subject surface, and outputs the result of measuring the reflected light. The size of the measurement region for reflectance characteristic measurement can be altered.
