Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of camera modules in electronic devices is hindered by the need for a thick protrusion to support the filter, which compromises the camera's structural strength and design.
Innovation Solution
A camera module design incorporating a supporting base with a metal sheet and a fixing member, where the metal sheet is hot-riveted onto the base using rivets, allowing for a thinner structure that effectively supports the filter while maintaining strength, and includes features like a blocking layer to reduce reflectivity and improve imaging quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the protrusion thickness is increased to support the filter, then the structural strength is improved, but the camera module size increases
Solution Approach 1:
The patent employs a composite structure combining metal sheet and plastic base material. The metal sheet provides enhanced mechanical strength and rigidity to support the filter, while the plastic base maintains the overall structural integrity. This composite approach allows the protrusion to achieve sufficient strength with reduced thickness, thereby minimizing camera module size while ensuring filter support stability.
2Volume of moving object
If the protrusion thickness is reduced for miniaturization, then the camera module size is reduced, but the structural strength deteriorates
Solution Approach 1:
By integrating a metal sheet into the plastic base structure, the patent achieves high strength-to-volume ratio. The metal sheet's superior mechanical properties compensate for the reduced protrusion thickness, enabling miniaturization without sacrificing the structural strength needed to support the filter effectively.
3Volume of moving object
If the camera module is miniaturized, then the device compactness is improved, but the filter support stability worsens
Solution Approach 1:
The metal sheet embedded in the plastic base creates a stable, rigid support structure for the filter. This composite construction provides excellent dimensional stability and resistance to deformation, ensuring filter support stability even in the miniaturized camera module configuration where traditional single-material designs would fail.

AI summary
A camera module includes a filter, a supporting base, a metal sheet, and a fixing member. The supporting base includes a first through hole, a first surface, and a second surface. A receiving groove is recessed from the second surface toward the first surface, an inner wall defining the receiving groove includes a bottom surface. The first through hole penetrates the first surface and the bottom surface. The metal sheet is received in the receiving groove and includes a second through hole. A central axis of the second through hole is collinear with a central axis of the first through hole. The metal sheet further includes a supporting platform exposed from the first through hole, the filter is mounted on the supporting platform and received in the first through hole. The fixing member is arranged on the supporting base to fix the metal sheet to the supporting base.
