Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate detecting unit with mechanical or electromagnetical structure is set at the outer edge to detect open or closed state, then the device can detect the two states of folding display device, but it is difficult to determine the specific degree of folding of the folding display device
Solution Approach 1:
The patent replaces the mechanical or electromagnetical detecting unit with a capacitive detecting electrode system. The capacitive electrode detects folding states through electrical field changes rather than mechanical contact, eliminating the need for complex mechanical structures while enabling precise detection of folding degrees through capacitance variations.
Solution Approach 2:
The patent introduces a capacitive detecting electrode as an intermediary element that senses folding states through electrical field interactions. This intermediary approach allows detection without direct mechanical contact, enabling precise measurement of folding degrees while maintaining device simplicity.
2Reliability
If a separate detecting unit is set at the outer edge of the two sides of the folding display device, then the device can monitor open or closed state, but the detecting unit occupies additional display area and reduces the effective display region
Solution Approach 1:
The patent merges the detecting electrode with the display panel structure itself. The capacitive detecting electrode is integrated into the display panel, eliminating the need for separate detecting units at the outer edges. This integration maintains detection reliability while preserving the full display area without occupation by external detecting components.
3Ease of operation
If a mechanical or electromagnetical detecting unit is used to detect folding states, then the device can identify open or closed state, but the detection is limited to two discrete states without intermediate position information
Solution Approach 1:
The patent implements a dynamic detection system using capacitive electrodes that can continuously measure folding degrees across the entire range of motion. The capacitive detection method provides real-time, continuous information about intermediate folding positions, transforming the discrete two-state detection into a continuous spectrum of folding degree measurements.
Solution Approach 2:
The patent utilizes changes in capacitance parameters to detect and quantify folding degrees. By measuring variations in capacitance values as the device folds, the system can determine specific folding positions with precision, providing continuous information about the folding state rather than limited binary states.
