Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex color picking devices are used to acquire color information, then color acquisition capability is improved, but device complexity increases and reliability decreases due to vulnerability to ambient light
Solution Approach 1:
The color picking device is segmented into distinct functional modules: light emitting module, color receiving module, lens assembly, and aperture. This segmentation allows each component to perform its specific function optimally while simplifying the overall structure and improving reliability.
Solution Approach 2:
The patent introduces an aperture as an intermediary element between the lens assembly and the color receiving module. This aperture acts as a spatial filter that blocks ambient light while allowing reflected light from the target object to pass through, thereby improving color acquisition accuracy without complicating the device structure.
2Adaptability or versatility
If color picking devices are equipped to acquire external object color, then lighting device adaptability is improved, but measurement precision deteriorates due to ambient light interference
Solution Approach 1:
The aperture serves as a spatial filter that selectively transmits light from the target object while blocking ambient light from surrounding areas. This intermediary element ensures that the color receiving module only detects reflected light from the illuminated surface, maintaining high measurement precision while enabling adaptability to different lighting environments.
Solution Approach 2:
The light emitting module directs light locally onto the target object surface, and the aperture creates a localized field of view for the color receiving module. This local quality approach ensures that color acquisition is performed on a specific illuminated area, preventing ambient light from other regions from interfering with the measurement.
3Device complexity
If simple color picking device structure is used, then device complexity is reduced, but measurement precision worsens due to inability to shield ambient light
Solution Approach 1:
The aperture is a simple structural element that acts as an effective intermediary to block ambient light. Despite its simplicity, it provides precise spatial filtering that maintains high measurement precision while keeping the overall device structure simple and reliable.
Solution Approach 2:
The patent replaces complex mechanical light shielding systems with a simple aperture structure combined with optical focusing. This substitution achieves the same ambient light rejection function with much simpler mechanics, maintaining measurement precision without increasing device complexity.
