Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fingerprint sensor is integrated into the display area, then user convenience and security are enhanced, but device complexity increases
Solution Approach 1:
The patent merges the fingerprint sensor with the display panel by integrating sensor portions directly into the display area and side surfaces. This combination eliminates the need for separate fingerprint recognition devices, thereby enhancing user convenience while managing device complexity through unified design.
Solution Approach 2:
The patent divides the fingerprint recognition function into multiple sensor portions positioned at different locations (display area and side surfaces). This segmentation allows flexible fingerprint input methods from various angles, improving ease of operation while distributing the complexity across multiple simpler sensor units.
2Adaptability or versatility
If multiple sensor portions are disposed at different locations, then fingerprint recognition flexibility is improved, but manufacturing complexity increases
Solution Approach 1:
The patent implements universal sensor portions that can detect fingerprints from multiple orientations and locations. These sensor portions serve multiple functions by recognizing fingerprints whether the user places their finger on the display area or side surfaces, thereby improving adaptability while using standardized sensor components that simplify manufacturing.
3Reliability
If sensor portions are integrated into display area and side surfaces, then security is enhanced, but device structure becomes more complex
Solution Approach 1:
The patent extends fingerprint recognition from the traditional single-plane display surface to multiple dimensions by incorporating sensor portions in both the display area and side surfaces. This multi-dimensional arrangement enhances security by providing multiple recognition zones while integrating sensors into existing structural elements, thereby managing overall device complexity.
