Solution Overview
Problem
Existing camera technologies in mobile devices face challenges in maximizing screen-to-body ratio while maintaining image capturing functionality, particularly in achieving efficient camera module protrusion, retraction, and rotation without compromising waterproof and dust-proof performance.
Innovation Solution
A camera assembly with a first driving structure for linear reciprocation and a second driving structure for rotational movement, utilizing a transmission system with a screw rod and nut mechanism, and a relay with an electromagnet and spring for independent control of camera modules, allowing the camera module to protrude, retract, and rotate within the device body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a pop-up camera mechanism is implemented to increase screen-to-body ratio, then the screen area increases, but the camera module protrusion and retraction reliability deteriorates
Solution Approach 1:
The camera module system is segmented into multiple independent camera modules (first camera module and second camera module) that can be independently controlled to protrude and retract. This segmentation allows selective operation of camera modules based on shooting requirements, improving reliability by ensuring that if one module encounters issues, the other can still function.
Solution Approach 2:
A relay structure is introduced as an intermediary component between the driving mechanism and the camera modules. The relay includes a blocking component that can selectively block or transmit the driving force, providing precise control over camera module protrusion and retraction. This intermediary mechanism enhances reliability by enabling controlled engagement and disengagement of the camera modules from the driving force.
2Adaptability or versatility
If multiple camera modules are added to enable front and rear camera switching, then the camera functionality improves, but the device complexity increases
Solution Approach 1:
Multiple camera modules are merged into a single integrated assembly that shares common structural components, driving mechanisms, and control systems. The first and second camera modules are positioned within the same housing and share the same protrusion/retraction mechanism, reducing overall device complexity compared to having completely separate camera systems.
Solution Approach 2:
The camera assembly is designed with universal components that serve multiple functions. The relay structure and driving mechanism can control both the first and second camera modules, making them multi-functional. The transmission bar and connecting components serve both structural support and mechanical transmission purposes for multiple camera modules simultaneously.
3Adaptability or versatility
If the camera module is designed to rotate for capturing images from different angles, then the adaptability improves, but the waterproof and dust-proof performance deteriorates
Solution Approach 1:
The camera module is designed with dynamic capabilities to rotate and change orientation for capturing images from different angles. The rotating mechanism allows the camera module to adjust its shooting direction while maintaining a sealed structure. The housing and connecting components are designed to maintain waterproof and dust-proof seals even during rotation movements.
Solution Approach 2:
The camera module housing and connecting components utilize flexible sealing structures that can accommodate rotation movements while maintaining waterproof and dust-proof performance. The sealing elements are designed to flex and adapt during rotation, ensuring continuous protection against water and dust ingress even when the camera module changes orientation.

AI summary
A camera assembly includes a first driving structure (1), a second driving structure (2), a transmission (3) and a camera module. The transmission (3) can cooperate with the first driving structure (1) to drive the camera module to reciprocate linearly in a preset direction, and the transmission (3) can cooperate with the second driving structure (2) to drive the camera module (4, 41, 42) to rotate about an axis in the preset direction.
