Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera technologies in mobile terminals require manual rotation of telescopic cameras, which increases user operation complexity and limits automatic rotation functionality after ejection from the terminal.
Innovation Solution
A camera apparatus with a rotating shaft, transmission component, screw rod, and control mechanism, where the screw rod drives the transmission component to move, and when it reaches a predetermined position, the first gear meshes with a second gear to automatically rotate the camera module, enabling automatic rotation after protrusion from the terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual rotation of telescopic camera is implemented, then camera rotation function is achieved, but user operation complexity increases
Solution Approach 1:
The camera module automatically rotates itself after ejection by utilizing the transmission mechanism comprising the screw rod, transmission component, and meshing gears. The system performs the rotation function without requiring manual intervention, making the device serve itself and eliminating the need for user operation for rotation.
Solution Approach 2:
The transmission mechanism is pre-configured with the screw rod and meshing gears in specific positions. When the camera module is ejected, the transmission component automatically engages with the gear system, which has been prepared in advance to drive rotation. This preliminary arrangement enables automatic rotation without requiring additional user actions.
2Adaptability or versatility
If telescopic camera structure is added, then camera functionality is improved, but device complexity increases
Solution Approach 1:
The patent combines the telescopic ejection mechanism with the rotation mechanism into a single integrated system. The transmission component that drives ejection also engages with the meshing gears to drive rotation, merging two functions (ejection and rotation) into one unified mechanism, thereby reducing overall device complexity while maintaining versatile camera functionality.
Solution Approach 2:
The screw rod and transmission component serve multiple functions: they drive the camera module outward for ejection, and simultaneously engage with the meshing gears to rotate the camera module. This multi-functionality reduces the need for separate mechanisms, simplifying the overall device structure while achieving both ejection and rotation capabilities.
3Extent of automation
If automatic rotation mechanism is added, then automation level is improved, but device complexity increases
Solution Approach 1:
The mechanism dynamically transitions between ejection mode and rotation mode. During ejection, the screw rod drives the transmission component outward; upon reaching the predetermined position, the transmission component automatically engages with the meshing gears, dynamically switching the system from linear motion to rotational motion. This dynamic behavior enables automatic rotation without requiring a completely separate rotation mechanism.
Solution Approach 2:
The transmission component acts as an intermediary between the screw rod and the camera module. It converts the linear motion from the screw rod into rotational motion through engagement with the meshing gears, serving as a mediator that enables automatic rotation while simplifying the overall mechanism by avoiding the need for separate motors or actuators for rotation.
