Camera Support Member Merging Fixing and Sub-PCB Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals with cameras require multiple components for assembly and fixing, complicating the process and increasing costs, while also being space-inefficient.
Innovation Solution
A support member with a rib and adhesive is used to fix the camera, which is grounded to the main PCB, reducing the number of components and simplifying assembly by using a single support member that also protects the camera and includes a spacer for the sub-PCB, with guide holes for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components (support member and camera fixing member) are used to support the sub-PCB and fix the camera, then the camera can be securely fixed and the sub-PCB can be supported, but the number of components increases and assembly complexity increases
Solution Approach 1:
The patent combines the support member and camera fixing member into a single integrated support member that performs both functions. The support member includes a camera fixing protrusion that directly secures the camera while the main body supports the sub-PCB, eliminating the need for separate fixing members and reducing component count.
Solution Approach 2:
The support member is designed as a multi-functional component that simultaneously supports the sub-PCB, fixes the camera, and provides structural reinforcement. This universal component replaces multiple specialized parts, simplifying the overall device structure while maintaining all necessary functions.
2Reliability
If multiple components are used for supporting and fixing, then secure mounting is achieved, but the assembling process becomes more complex and costly
Solution Approach 1:
By merging the support and camera fixing functions into a single component, the assembly process requires fewer steps and fewer parts to be handled separately. The integrated design allows for simpler assembly operations while maintaining secure mounting of both the camera and sub-PCB.
3Reliability
If traditional separate components are used, then each component can be optimized for its specific function, but space utilization becomes inefficient
Solution Approach 1:
The integration of multiple functions into a single support member eliminates the need for separate components that would occupy additional space. The consolidated design allows for more efficient space utilization within the terminal body while maintaining all necessary functional capabilities.
4Device complexity
If a single support member is used to fix the camera and support the sub-PCB, then the number of components is minimized and assembly is simplified, but the support member must perform multiple functions
Solution Approach 1:
The support member is specifically designed with multiple functional features: a main body for supporting the sub-PCB, a camera fixing protrusion for securing the camera, and appropriate mounting interfaces for attachment to the terminal body. This multi-functional design consolidates what would traditionally require multiple separate components.
