Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional color sensor-equipped styluses are used, then color capture function is provided, but vivid colors cannot be captured under insufficient light conditions
Solution Approach 1:
The patent applies preliminary action by illuminating the object surface with an LED light source before the color sensor captures the color. This pre-illumination ensures that sufficient light is available for accurate color measurement even in insufficient light conditions, directly resolving the contradiction between color capture accuracy and light intensity requirements
2Ease of operation
If color sensor is positioned away from object surface, then operational comfort is improved, but color capture accuracy deteriorates
Solution Approach 1:
The patent uses preliminary action by providing light illumination before color capture, which allows the color sensor to be positioned at a comfortable distance from the object while still achieving accurate color measurement. The pre-illumination compensates for the increased distance, maintaining measurement precision without compromising operational comfort
3Stability of the object's composition
If color input unit is rigidly fixed, then structural stability is improved, but adaptability to different surfaces deteriorates
Solution Approach 1:
The patent applies dynamics by making the color input unit elastically bendable rather than rigidly fixed. The elastic connection allows the color input unit to adapt its shape to different object surfaces while maintaining structural stability through the elastic restoring force, thus resolving the contradiction between structural stability and surface adaptability
4Measurement precision
If color input unit contacts object surface directly, then color capture accuracy is improved, but light interference increases
Solution Approach 1:
The patent extracts the light source function from the surrounding environment and incorporates it into the color input unit itself. By including an LED light source within the color input unit, the system becomes self-sufficient for illumination and is no longer affected by surrounding light conditions, thus eliminating light interference while maintaining color capture accuracy through direct surface contact
