Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional touch detection methods are used to adjust light diffusion degree, then individual adjustment of diffusion degree in two directions is required, but this increases operational complexity and reduces intuitiveness
Solution Approach 1:
The detection region is segmented into multiple determination regions (first determination region, second determination region, third determination region, fourth determination region) corresponding to different directional components. Each determination region detects touch operations for adjusting light diffusion in specific directions, allowing independent control of diffusion degree in two directions through separate touch gestures.
Solution Approach 2:
The patent extends conventional single-dimension touch detection to two-dimensional directional control by arranging determination regions in a matrix pattern. Touch operations in different spatial dimensions (horizontal and vertical directions) correspond to adjusting light diffusion degree in respective directions, enabling intuitive 2D control through 2D touch interface.
2Manufacturing precision
If multiple liquid crystal cells for p-wave and s-wave polarization are used to control light diffusion in two directions, then precise light distribution control is achieved, but the control mechanism becomes more complex
Solution Approach 1:
The control mechanism is segmented into multiple independent determination regions, each responsible for detecting touch operations for specific directional adjustments. This segmentation allows the complex task of controlling multiple liquid crystal cells to be divided into simpler, independent sub-tasks that can be processed separately and combined.
Solution Approach 2:
The touch sensor with multiple determination regions acts as an intermediary between user input and the liquid crystal cells. Instead of directly controlling multiple liquid crystal cells, the system uses touch detection in different regions as an intermediate step that translates user gestures into appropriate control signals for the liquid crystal cells.

AI summary
A control device for an illumination device is configured to control an illumination device by controlling a diffusion degree of light emitted from a light source. The control device includes: a touch sensor having a detection region; and a display panel provided with a display region overlapping the detection region of the touch sensor in plan view. A determination region provided in the detection region and configured to detect a predetermined touch operation. Touch operations to be detected in the determination region include a first touch operation defined by at least one of the number of touches or the duration of touch in the determination region and a second touch operation different from the first touch operation. The diffusion degree of the illumination device is increased when the first touch operation is detected. The diffusion degree of the illumination device is decreased when the second touch operation is detected.
