Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to integrate a photosensor module into a terminal's outer frame due to the need for light-transmitting holes, which can compromise mechanical stability and manufacturing complexity, especially in thin devices where space is limited.
Innovation Solution
An outer frame with a light-transmitting structure and member that allows light to pass through while maintaining structural integrity, using a light-transmitting and shielding layer to absorb or reflect light, reducing the need for open pores and enhancing shielding properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light-transmitting holes are formed in the outer frame to integrate photosensor modules, then photosensor functionality is achieved, but mechanical stability and structural integrity are compromised
Solution Approach 1:
The patent transitions from a 2D surface opening (light-transmitting hole) to a 3D integrated structure where the light-transmitting member is embedded within the outer frame's thickness. This dimensional change allows light transmission while maintaining the outer frame's structural integrity by utilizing the third dimension (depth) rather than creating surface openings.
Solution Approach 2:
The light-transmitting member is nested within the outer frame structure, with the outer frame enclosing the light-transmitting member. This nesting arrangement allows the photosensor module to be integrated while the outer frame continues to provide mechanical support and stability, as the light-transmitting member is contained within rather than removing material from the frame.
2Adaptability or versatility
If open pore structures are used in the outer frame for light transmission, then photosensor operation is enabled, but manufacturing complexity increases
Solution Approach 1:
The patent employs a light-transmitting member with open pore structures that allow light to pass through while maintaining structural integrity. These porous materials provide the necessary light transmission capability for photosensor operation without requiring complex manufacturing processes to create the pores, as the porosity is inherent to the material structure rather than requiring post-processing operations.
3Illumination intensity
If the outer frame uses transparent materials for light transmission, then photosensor functionality is achieved, but shielding performance deteriorates
Solution Approach 1:
The outer frame is designed with spatially varying optical properties: the light-transmitting member region allows light transmission for photosensor operation, while other regions of the outer frame maintain shielding properties. This local differentiation of material properties enables simultaneous light transmission where needed and light blocking where required, without compromising overall device performance.
Solution Approach 2:
The outer frame structure combines different material types with complementary properties: transparent or light-transmitting materials in regions requiring light passage, and opaque or light-blocking materials in regions requiring shielding. This composite construction allows the frame to simultaneously provide both light transmission and light shielding functions in different locations.
