Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If iris recognition sensors are integrated to enhance security, then security protection is improved, but device complexity increases
Solution Approach 1:
The camera module is designed to perform multiple functions: iris recognition, proximity sensing, and super proximity sensing. The processor selectively activates different sensing modes based on application requirements, allowing one component to serve multiple security and operational purposes, thereby improving security without proportionally increasing device complexity
Solution Approach 2:
The patent combines the light emitting module, camera, and processor into an integrated sensing system. By merging these components and enabling the camera to perform both iris recognition and proximity sensing functions, the system achieves enhanced security capabilities while reducing the need for separate dedicated components
2Adaptability or versatility
If multiple sensing functions are performed based on application type, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system dynamically switches between different sensing modes (iris sensing, proximity sensing, super proximity sensing) based on the type of application being executed. The processor selectively activates the appropriate sensing function in real-time, allowing the device to adapt to different operational contexts without maintaining all sensing capabilities simultaneously, thus improving adaptability while managing complexity
Solution Approach 2:
The camera module is designed as a universal sensing component that can perform multiple sensing functions depending on application requirements. This multi-functionality allows the system to adapt to various scenarios (security authentication, proximity detection, super proximity detection) using a single integrated component rather than multiple dedicated sensors
3Measurement precision
If camera is spaced apart from light emitting module by specific distance, then iris sensing precision is improved, but device area increases
Solution Approach 1:
The patent specifies a particular spatial arrangement where the camera is positioned at a specific distance from the light emitting module. This localized optimization of the optical path ensures that iris reflection patterns are captured with high precision for accurate recognition, while the overall device area is managed by integrating this specific configuration into a compact sensing module
