Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The implementation of a full screen on mobile devices is hindered by the need for openings for sensors and antennas, which reduces the screen area ratio and aesthetic appeal.
Innovation Solution
Incorporating a laser sensor aligned with a through hole in the frame of the display panel, allowing signal emission and reception without additional front panel openings, and using a processor to configure power and gain settings based on alignment with the hole for efficient signal transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional openings are provided on the front panel for installing sensors, then sensor functionality is achieved, but the screen area ratio is reduced
Solution Approach 1:
The patent merges the sensor opening function with the existing through hole in the frame structure. The laser sensor is installed in the through hole, combining the structural support function of the frame with the sensor mounting function, thereby eliminating the need for separate front panel openings while maintaining sensor functionality
Solution Approach 2:
The patent relocates the sensor from the traditional front panel position to the frame's through hole, utilizing a different spatial dimension and location. This dimensional shift allows the sensor to function without occupying front panel area, thus preserving the screen area ratio while achieving sensor capability
2Area of stationary object
If the laser sensor is aligned with the through hole for signal transmission, then the area ratio of the display is enhanced, but the complexity of configuration increases
Solution Approach 1:
The patent implements preliminary alignment configuration during the device assembly stage. The laser sensor is pre-positioned and aligned with the through hole in the frame, and the processor is pre-configured with the appropriate power and gain settings. This preliminary action eliminates the need for complex runtime adjustments while maintaining optimal display area ratio and signal transmission efficiency
