Interlocked Camera Module Frame with Metal Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera modules in portable electronic devices face challenges in securely supporting optical assemblies during impact or shock events, as existing structures may add bulk and fail to maintain the optical assembly's position relative to the image sensor, leading to potential delamination and misalignment.
Innovation Solution
A camera module frame with a reinforcement member and a base member, where the reinforcement member is made from metal and the base member from polymer, forming a composite structure that includes openings and ridges to increase the retention force between the members, preventing delamination and maintaining the optical assembly's position during unexpected movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frame structure is used to support the optical assembly, then the optical assembly is held in position, but the frame may delaminate or fail during impact or shock events
Solution Approach 1:
The frame is constructed as a composite structure with a reinforcement member (metal) and a base member (polymer) that are interlocked together. The reinforcement member provides structural strength while the base member provides retention capability, creating a composite material solution that simultaneously improves both strength and reliability.
Solution Approach 2:
The frame is divided into two distinct members: a reinforcement member and a base member. Each member is optimized for its specific function - the reinforcement member for structural integrity and the base member for retention - and they are joined through an interlocking structure with openings that allow them to work together as a unified system.
2Reliability
If support structures are added to hold the optical assembly, then the optical assembly position is maintained, but the camera module dimensions increase
Solution Approach 1:
The frame is segmented into two functional members that work together within the existing camera module volume. The reinforcement member and base member are interlocked in a way that maximizes structural efficiency within the available space, avoiding the need for additional bulk while maintaining optical assembly position stability.

AI summary
A camera module may have an optical assembly, an image sensor, and a frame, where the frame includes a reinforcement member and a base member that collectively form a sidewall of the frame. The reinforcement member defines a portion of the sidewall of the frame, a peripheral edge, and an opening. The base member may define another portion of the sidewall and extend through the opening and surround the peripheral edge of the reinforcement member. The optical assembly may be coupled to the sidewall of the frame.
