Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The width of the screen frame in mobile devices is limited by the image module, which includes a circuit board and a lens base, preventing further narrowing and thus limiting the screen ratio and increasing device weight.
Innovation Solution
An image capturing module with a long circuit board and a lens base, where the lens base is designed with a substrate and side plates that are fixed to the circuit board with light-shielding adhesive layers to create notches, reducing the overall width and allowing for a narrower screen frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lens base is designed with conventional width to enclose the light sensor, then the light sensor is protected and enclosed in the cover, but the overall width of the image module is increased, preventing the screen frame from being narrowed
Solution Approach 1:
The lens base transitions from a conventional wide cover shape to a narrow U-shaped structure with side plates extending downward. This dimensional change allows the light sensor to be enclosed vertically rather than horizontally, reducing the overall width of the image module while maintaining sensor protection
Solution Approach 2:
The lens base is segmented into a substrate and two side plates that are separately formed and then integrated. This segmentation allows the side plates to be positioned closer to the substrate, creating notches that reduce the overall width while maintaining the enclosing function for the light sensor
2Area of stationary object
If the screen frame width is reduced to increase screen ratio, then the display area is increased, but the image module width becomes the limiting factor that prevents further narrowing
Solution Approach 1:
The lens base adopts a U-shape configuration with side plates extending downward from the substrate, changing the enclosure geometry from horizontal to vertical. This allows the image module width to be reduced while maintaining the light sensor enclosure, thereby enabling the screen frame to be narrowed and display area increased
Solution Approach 2:
The side plates are positioned at specific locations with optimized width and spacing to create notches, allowing local reduction in width while maintaining the enclosing function. This localized optimization enables overall width reduction without compromising the light sensor protection

AI summary
An image capturing module includes a long circuit board, a lens base, and two light-shielding adhesive layers. The long circuit board includes a surface having an assembly area. The assembly area has two opposite long sides and two opposite short sides. The assembly area is provided with a light sensor. The two long sides are separated by a specific width. The lens base includes a substrate and two side plates. The two side plates are connected to opposite sides of the substrate and are respectively fixed on the two short sides of the assembly area. A specific spacing is maintained between the substrate and the assembly area to form two notches between the two long sides and the substrate. The width of the substrate and each of the side plates is less than or equal to the specific width. The two light-shielding adhesive layers respectively close the two notches.
