Solution Overview
Problem
Existing camera assemblies in electronic devices lack adaptability, making them prone to damage and pollution, and do not allow for easy rotation or retraction for optimal use.
Innovation Solution
A camera assembly with a motor-driven connecting rod, electromagnetic components, and an elastic component that allows the camera module to rotate between a preset position for photography and an initial position for retraction, using electromagnetic forces and elastic deformation for controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera module is fixed inside the electronic device, then the device structure is simple, but the camera adaptability is poor and it is prone to damage and pollution
Solution Approach 1:
The camera module is transformed from a fixed static structure to a dynamic movable structure. The driving module enables the camera module to move between a retracted position (inside the electronic device) and an extended position (outside the electronic device), allowing the camera to adapt to different usage scenarios while maintaining protection when not in use.
Solution Approach 2:
The camera assembly is divided into independent functional modules: the camera module itself, the driving module with electromagnetic components, the connecting rod mechanism, and the elastic component. This segmentation allows each module to perform its specific function independently and facilitates easier manufacturing and maintenance.
2Adaptability or versatility
If the camera module is movable to improve adaptability, then the camera can be extended and retracted, but the device structure becomes more complex
Solution Approach 1:
The traditional mechanical driving mechanism is replaced with an electromagnetic driving system. The first electromagnetic component generates electromagnetic force to drive the connecting rod and camera module, eliminating the need for complex mechanical gears, linkages, or motors, thereby simplifying the overall structure while achieving precise control.
Solution Approach 2:
The first electromagnetic component serves multiple functions: it generates the driving force for extending the camera module, provides magnetic attraction for positioning, and works in conjunction with the elastic component to enable controlled retraction. This multi-functionality reduces the need for separate components for each function.
3Ease of operation
If the camera module is always exposed for easy access, then the ease of operation is improved, but the camera is more susceptible to damage and pollution
Solution Approach 1:
The camera module is pre-positioned in a retracted state inside the electronic device when not in use, providing automatic protection against damage and pollution. When needed, the driving module quickly extends the camera module to the operational position, ensuring both protection and ease of operation.
Solution Approach 2:
The elastic component is pre-compressed or pre-tensioned to provide cushioning force during the camera module's movement. This cushioning effect protects the camera module from shock and impact during extension and retraction, and also provides a restoring force for automatic retraction to the protected position.
