Mobile Terminal Photosensitive Device Optical Channel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of mobile terminals with photosensitive devices on the front side limits the screen-to-body ratio, restricting the increase of display area and aesthetic appeal.
Innovation Solution
The photosensitive device is repositioned to use structural assembly gaps between the display screen, middle frame, and edge frame as an optical channel, eliminating the need for a dedicated space on the front, thereby increasing the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the photosensitive device is arranged on the front side of the mobile terminal, then the photosensitive device can perform its sensing function, but the screen-to-body ratio is reduced
Solution Approach 1:
The patent moves the photosensitive device from the traditional front-side horizontal arrangement to a side-mounted vertical arrangement, utilizing the side frame space. This dimensional relocation allows the device to perform its sensing function while eliminating the need to occupy front display area, thereby resolving the contradiction between device functionality and screen-to-body ratio.
Solution Approach 2:
The photosensitive device is extracted from the front side arrangement and relocated to the side frame. This extraction removes the conflicting element from the display area, allowing the screen-to-body ratio to increase while the device maintains its sensing capability through the optical channel provided in the side frame.
2Device complexity
If the photosensitive device is arranged on the front side, then the device structure is simple, but the display area is reduced
Solution Approach 1:
By relocating the photosensitive device to the side frame and creating an optical channel through the middle frame, the patent redistributes spatial resources. This dimensional change allows the display area to expand to the full front surface while the device structure adapts to a new spatial configuration that maintains functionality without reducing display area.
3Ease of manufacture
If the photosensitive device is arranged in the front side, then the arrangement is straightforward, but the aesthetic feeling is reduced
Solution Approach 1:
The photosensitive device is extracted from the front side and relocated to the side frame. This extraction eliminates the visual obstruction on the front surface, improving aesthetic appearance and enabling full-screen display design. The device remains easily manufacturable through the standardized optical channel structure provided in the side frame and middle frame.
