Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unilaterally-driven design is used in the pop-up camera, then the structure is simple, but the camera is prone to tilting under unbalanced load and may get stuck
Solution Approach 1:
The patent introduces a transmission push rod with an elastic arm that acts as a counterbalancing mechanism. The elastic arm is pre-loaded to generate a counteracting force that balances the gravitational force on the camera module, preventing tilting under unbalanced load conditions while maintaining structural simplicity
2Manufacturing precision
If the transmission push rod is rigid, then the transmission is precise, but it cannot adapt to tilting trends caused by processing errors or wear
Solution Approach 1:
The patent transforms the rigid transmission push rod into a dynamic structure by adding an elastic arm that can flex and adjust its angle. This allows the transmission mechanism to adapt to tilting trends caused by processing errors or wear while maintaining precise transmission through the elastic connection
3Adaptability or versatility
If the transmission portion is made flexible to adjust working attitude, then self-adaptive capability is improved, but the structure becomes more complex
Solution Approach 1:
The patent segments the transmission push rod into a rigid body portion and a flexible elastic arm portion. This segmentation allows the elastic arm to provide self-adaptive capability for adjusting working attitude while the rigid body maintains precise transmission, avoiding excessive overall structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents tilting and ensures smooth, reliable operation of the camera, enhancing user experience by allowing bidirectional switching and reducing the risk of getting stuck, while optimizing field of view utilization and maintaining structural integrity.
Implementation Method 1
the elastic arm is configured to be capable of being deformed on the plane relative to the body of the transmission push rod under pressing of the transmission surface, to change a working attitude

AI summary
An electronic device discloses a transmission push rod in transmission connection with a camera carrier. The transmission push rod is provided with a transmission portion capable of adjusting a working attitude. When the transmission push rod generates a tilting trend relative to the camera carrier, the transmission portion that presses against a transmission surface by using a transmission end is capable of changing a working attitude relative to a body of the transmission push rod, and the transmission end keeps in line contact with the transmission surface. Therefore, for the tilting phenomenon, a self-adaptive capability is provided, so that a tilting trend of the camera carrier generated with the transmission push rod can be avoided, and a phenomenon of getting stuck is avoided.
