Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-touch operation with four or more fingers is implemented, then operation complexity increases, but ease of operation deteriorates
Solution Approach 1:
The patent segments the authentication function into multiple independent fingerprint sensors positioned at different locations on the device. Each sensor can independently detect a fingerprint, allowing the system to identify multiple fingers simultaneously without requiring complex multi-touch detection algorithms. This segmentation simplifies the overall operation while maintaining versatility.
Solution Approach 2:
The fingerprint sensors serve multiple functions: they authenticate individual fingers, verify combinations of fingers, and enable both simple and complex operations. By making the authentication system universal, the device can handle various operation types (from single-finger to multi-finger operations) without adding separate detection mechanisms, thus improving ease of operation while maintaining adaptability.
2Reliability
If authentication technology is added to prevent abuse, then security level improves, but device complexity increases
Solution Approach 1:
The patent merges the authentication function with existing device components by integrating fingerprint sensors into the housing or display structure. Rather than adding separate authentication modules, the fingerprint detection capability is combined with structural elements already present in the device, thereby improving security while minimizing increases in device complexity.
Solution Approach 2:
The fingerprint sensors are designed to serve multiple authentication scenarios: single-finger authentication, multi-finger combination verification, and differentiated access levels. This universal authentication mechanism handles various security requirements without requiring separate authentication systems for each scenario, thus improving security level while controlling device complexity.
3Ease of operation
If fingerprint sensor is integrated into push button switch portion, then ease of operation improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the fingerprint sensing function from the mechanical push button function, allowing each to be optimized independently. The fingerprint sensors are positioned in specific locations on the housing or display, separate from the button mechanism, enabling easier integration with existing structures and reducing the need for high-precision coordination between sensing elements and mechanical components.
