Display Sensing Module Embedded Fixation for Smooth Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses have a protruding structure for fixing the light receiving part, resulting in a non-smooth lower surface and increased front surface area, which complicates the assembly process and affects the appearance and performance of the device.
Innovation Solution
The display apparatus incorporates a sensing module with a substrate and module cabinet configuration that includes insertion grooves and brackets, allowing for stable fixation without additional fastening members, reducing the device's width and improving the arrangement of light receiving and emitting parts, thus enhancing the external appearance and assembly simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light receiving part is coupled to the lower side of the lower frame using a protruding structure, then the light receiving part can be fixed to the display apparatus, but the lower surface becomes non-smooth and the front surface area increases
Solution Approach 1:
The patent transitions from a protruding structure extending downward to create a non-smooth surface, to an embedded structure where the light receiving part is recessed into the lower frame. This dimensional repositioning allows the upper surface to remain flush and smooth while the fixing structure exists in the lower dimension, resolving the contradiction between fixation stability and surface smoothness
2Reliability
If the light receiving part is coupled to the lower side of the lower frame, then the light receiving part can be fixed, but the assembly process becomes complicated
Solution Approach 1:
The patent integrates the light receiving part directly into the lower frame structure, merging two separate components (light receiving part and lower frame) into a unified assembly. The recessed structure allows the light receiving part to be embedded within the lower frame, eliminating the need for separate protruding fixing mechanisms and simplifying the assembly process while maintaining stable fixation
3Reliability
If the light receiving part is coupled to the lower side of the lower frame, then the light receiving part can be fixed, but the device width increases
Solution Approach 1:
The patent implements a nested configuration where the light receiving part is recessed into the lower frame, with the light receiving part fitting within the dimensional envelope of the lower frame. This nesting approach allows the light receiving part to be securely fixed while occupying no additional external space, thereby maintaining a compact device width
