Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate detectors are used for touch detection and fingerprint detection, then detection functionality is ensured, but device size increases
Solution Approach 1:
The patent applies multi-functionality by enabling a single detector to perform both touch detection and fingerprint detection functions. The detector can operate in different modes: detecting proximity touches when an object approaches the surface, and detecting fingerprint patterns when an object makes direct contact. This eliminates the need for separate detectors for each function, thereby reducing device size while maintaining comprehensive detection capabilities.
Solution Approach 2:
The patent merges touch detection and fingerprint detection functions into a single integrated detector system. By combining these functions that were previously performed by separate detectors, the overall device volume is reduced while maintaining both detection capabilities through a unified detection mechanism.
2Adaptability or versatility
If multiple detectors are integrated, then detection capabilities are enhanced, but device complexity increases
Solution Approach 1:
The patent reduces device complexity by implementing a universal detector that handles multiple detection tasks. Instead of managing separate detectors for touch and fingerprint detection, the system uses a single detector that can switch between detection modes, thereby simplifying the overall device architecture while maintaining versatile detection capabilities.
3Ease of manufacture
If detector integration is implemented, then manufacturing cost is reduced, but signal processing complexity increases
Solution Approach 1:
The patent manages signal processing complexity through dynamic mode switching. The detector can dynamically transition between proximity detection mode and contact detection mode based on the detection scenario. This dynamic operation allows the system to process signals appropriately for each mode while maintaining a simplified hardware architecture that benefits from integration.
