Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the watch case is placed in a thermal protection housing, then the mechanical and functional components are protected from temperature extremes, but the display device contrast becomes difficult to read in varying ambient brightness conditions
Solution Approach 1:
The patent implements a dynamic brightness adjustment system where the crystal's luminance is continuously adapted based on ambient light conditions detected by sensors. This dynamic adjustment resolves the contradiction by making the display readable across varying brightness environments while maintaining thermal protection, transforming a static thermal housing into an adaptive optical system.
Solution Approach 2:
The system employs event sensors to detect ambient brightness changes and provides feedback to the control unit, which adjusts the crystal's luminance accordingly. This closed-loop feedback mechanism ensures the display maintains optimal contrast ratios regardless of external lighting conditions, resolving the readability issue while preserving thermal protection functionality.
2Ease of operation
If a reversible fastening device is used to secure the watch case, then the case can be easily removed and reattached, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical fastening systems with a simplified attachment mechanism that enables easy case removal and reattachment. This substitution reduces device complexity while maintaining ease of operation, allowing users to access the watch case without requiring sophisticated tools or procedures.
3Illumination intensity
If the crystal surface area is increased to improve visibility, then the display is more readable, but the amount of light radiation entering the enclosure increases
Solution Approach 1:
The patent adjusts the crystal's luminance parameters dynamically based on ambient light conditions rather than simply increasing its physical surface area. By controlling the intensity and spectral characteristics of the crystal's light emission, the system achieves improved visibility without proportionally increasing harmful light radiation entering the thermal enclosure.
