Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate sensing devices are added to mobile apparatuses to provide ambient light sensing, color temperature sensing, gesture recognition, and proximity sensing functions, then the sensing capabilities and user experience are improved, but the total cost and space requirements increase
Solution Approach 1:
The patent applies multi-functionality by designing a single detection device that can perform multiple sensing functions including ambient light sensing, color temperature sensing, gesture recognition, and proximity sensing. The detection device uses different detection modes with an infrared light generating device to achieve various sensing capabilities, eliminating the need for multiple separate sensing devices and thereby reducing space requirements while maintaining comprehensive sensing functionality
