Mobile Terminal Receiver Layout for Higher Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As mobile terminals integrate more components to offer diverse functions, they become larger and thicker, failing to meet user demands for thinner and lighter designs due to increased body size.
Innovation Solution
The terminal device includes a main unit and a detachable sub-unit with a display screen, main and auxiliary circuit boards, and a piezoelectric ceramic receiver, where the receiver is positioned in an avoiding groove on the circuit boards, eliminating the need for a receiver hole on the display screen, thus increasing the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more components are integrated into the mobile terminal to provide diverse functions, then the functionality and versatility of the terminal are improved, but the body size of the terminal increases, making it thicker and heavier
Solution Approach 1:
The patent applies nesting by placing the piezoelectric ceramic receiver inside an avoiding groove that is formed within the circuit board structure itself. The groove is created by removing material from the circuit board, allowing the receiver to be embedded within the existing component layer rather than adding external bulk. This nested arrangement enables the receiver to be integrated into the circuit board's internal space, reducing the overall terminal thickness and weight while maintaining all required functions.
2Adaptability or versatility
If more components are integrated into the mobile terminal to provide diverse functions, then the functionality and versatility of the terminal are improved, but the body size of the terminal increases
Solution Approach 1:
The piezoelectric ceramic receiver is nested within an avoiding groove formed in the circuit board. The groove is created by selectively removing material from the circuit board at the position where the receiver will be placed. This allows the receiver to be embedded within the circuit board's thickness rather than extending beyond it, thereby reducing the overall terminal thickness while accommodating the additional functional component.
Solution Approach 2:
The patent transitions from a two-dimensional surface mounting approach to a three-dimensional embedded arrangement. Instead of placing the receiver on the surface of the circuit board (which would increase terminal thickness), the receiver is positioned within the thickness dimension of the circuit board itself by creating an avoiding groove. This dimensional reorganization allows the receiver to occupy space within the existing thickness budget rather than adding to it.
3Ease of manufacture
If a receiver hole is provided on the display screen to accommodate the piezoelectric ceramic receiver, then the receiver can be mounted, but the screen-to-body ratio is reduced
Solution Approach 1:
The patent extracts the receiver mounting function from the display screen by relocating the receiver to the circuit board. The avoiding groove is formed in the circuit board rather than in the display screen, thereby removing the need for a receiver hole in the screen. This extraction preserves the full display screen area while still providing a mounting location for the receiver in the circuit board layer.
Solution Approach 2:
The circuit board serves as an intermediary structure that provides the mounting location for the receiver. Instead of directly mounting the receiver on the display screen (which would require a hole in the screen), the circuit board acts as an intermediate platform with an avoiding groove that accommodates the receiver. This intermediary arrangement allows the receiver to be mounted without compromising the display screen integrity or reducing the screen-to-body ratio.
