Solution Overview
Problem
The increasing complexity of mobile phones with functions like distance detection, ambient light detection, and 3D face recognition requires a large number of functional elements such as proximity sensors, ambient light sensors, and infrared cameras, leading to space occupancy issues within the device.
Innovation Solution
An electronic device design that integrates an output component with a packaging shell housing both an infrared supplementary lighting lamp and a proximity infrared lamp on the same substrate, along with a proximity sensor, to enable simultaneous infrared supplementary lighting and distance measurement, reducing the overall size and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functional elements (proximity sensor, ambient light sensor, infrared camera, structured light projector) are arranged separately in the electronic device, then each function can be independently realized, but the space occupied in the mobile phone increases excessively
Solution Approach 1:
The patent combines the infrared supplementary lighting lamp and proximity infrared lamp into a single packaging shell with a unified substrate, integrating multiple light-emitting components that were previously separate. This merging reduces the total space required while maintaining all necessary functions for distance detection, ambient light detection, and 3D face recognition
Solution Approach 2:
The packaging shell structure serves multiple functions simultaneously: it houses both the infrared supplementary lighting lamp and proximity infrared lamp, provides structural support, and enables both supplementary lighting and proximity detection functions through a single integrated component arrangement, reducing the need for separate housings for each function
2Ease of manufacture
If the infrared supplementary lighting lamp and proximity infrared lamp are packaged separately, then each component can be optimized independently, but the overall device size increases
Solution Approach 1:
Both the infrared supplementary lighting lamp and proximity infrared lamp are packaged together in a single packaging shell and mounted on the same substrate, merging two previously separate packaging structures into one unified component. This reduces the overall volume occupied by these infrared lighting components while maintaining independent optimization of each lamp type through their respective design parameters
