Lens Module Connector Placement in Portable Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices face space constraints on printed circuit boards due to the need for a large unused area around loudspeakers to maintain amplification, which limits the placement of taller electronic elements and requires noise-generating components to be positioned outside, reducing usable space and potentially interfering with antenna signals.
Innovation Solution
The design incorporates a housing with a continuous wall and notch surrounding the loudspeaker division, allowing the lens module connector to be placed within the loudspeaker area, enabling more efficient use of printed circuit board space and flexible arrangement of electronic elements, including taller components like GSM connectors, while minimizing electromagnetic interference with the antenna.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large unused area is kept around the loudspeaker on the printed circuit board to maintain amplification, then the amplifying effect is improved, but the usable space for placing electronic elements is reduced
Solution Approach 1:
The printed circuit board is divided into distinct functional areas: a loudspeaker area with a large unused area for maintaining amplification, and other areas for placing electronic elements. The housing is also segmented into a loudspeaker division and other divisions, allowing spatial separation of functions.
Solution Approach 2:
The lens module connector is designed with a flexible circuit board that can bend and extend into the loudspeaker area through a notch in the continuous wall, utilizing the third dimension (depth/height) to access space that would otherwise be unavailable on the two-dimensional board surface.
2Area of stationary object
If taller electronic elements are disposed on the unused area of the printed circuit board, then more components can be placed, but through holes must be formed through the loudspeaker which decreases amplifying effect
Solution Approach 1:
The lens module connector uses a flexible circuit board that bends at an angle to extend into the loudspeaker area through a notch, utilizing vertical/depth space rather than horizontal space on the board surface. This allows tall components to be placed without forming through holes in the loudspeaker.
Solution Approach 2:
The flexible circuit board is nested within the housing structure, with portions extending through notches in the continuous wall to access the loudspeaker area. The lens module connector is effectively nested within the housing while maintaining electrical connection to the printed circuit board.
3Object-affected harmful factors
If electronic elements that generate noise are disposed outside the unused area, then noise interference is reduced, but the actual usable space of the printed circuit board decreases
Solution Approach 1:
The printed circuit board and housing are segmented into distinct functional zones: a loudspeaker area kept free of noise-generating elements for optimal acoustic performance, and other areas for placing electronic elements. The continuous wall with notches provides physical separation while allowing controlled access.
Solution Approach 2:
The lens module connector utilizes the flexible circuit board's ability to bend and extend through notches in the continuous wall, accessing the loudspeaker area through the third dimension rather than occupying horizontal space on the board surface, thereby avoiding noise interference while maximizing usable area.
