Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display luminance is increased to improve visibility for remote operation, then the visibility is improved, but the user confidentiality is compromised
Solution Approach 1:
The display luminance is made dynamic rather than static, automatically adjusting based on the detected inclination of the virtual input surface. When the surface is highly inclined (indicating remote operation), luminance increases for visibility; when the surface is flat (indicating close proximity), luminance decreases for confidentiality. This dynamic adaptation resolves the contradiction between visibility and confidentiality requirements.
2Loss of information
If the virtual input surface inclination is used to control luminance for enhancing confidentiality, then the confidentiality is improved, but the device complexity increases
Solution Approach 1:
The system implements a feedback loop where the motion detector continuously monitors the inclination of the virtual input surface, and this information is fed back to the luminance controller which adjusts display luminance accordingly. This automated feedback mechanism enhances confidentiality without requiring complex manual control systems, as the adjustment happens automatically based on detected user behavior patterns.
3Reliability
If the lock processor restricts operations based on virtual input surface inclination to prevent unauthorized access, then the security is improved, but the ease of operation is reduced
Solution Approach 1:
The lock processor utilizes changes in the inclination parameter of the virtual input surface to control access. When the inclination exceeds a predetermined threshold (indicating remote operation), the lock is released allowing operations; when the inclination is below the threshold (indicating close proximity), the lock restricts operations. This parameter-based control provides security against unauthorized access while maintaining ease of operation for legitimate users through natural motion patterns.
