Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the camera module is installed close to the antenna in the electronic device, then the device structure can be more compact, but the transmitting and receiving performance of the antenna is degraded due to spatial interference
Solution Approach 1:
The patent creates an empty space in the vertical dimension above the camera module by designing the transmission module with a specific gear arrangement where the driven gear is positioned lower than the intermediate gear. This vertical spatial separation allows the antenna to be placed above the camera module without interference, resolving the contradiction between compact device structure and antenna performance by utilizing the third dimension (height) for spatial separation.
2Adaptability or versatility
If the transmission module is designed with multiple gears and rotating shafts to enable camera module movement, then the camera module can be driven to move for direction turning, but the structure complexity increases and occupies more space
Solution Approach 1:
The patent combines the camera module driving function and the direction turning function into a single integrated transmission module. The motor, transmission module, and camera module form an integrated assembly where the same gears and rotating shafts that drive camera module movement also enable direction turning, thereby reducing overall structural complexity while maintaining both functionalities.

AI summary
The present disclosure provides a camera assembly (23) and an electronic device (100). The camera assembly (23) includes a camera module (231), a motor (232) and a transmission module (233). The transmission module (233) is connected between the camera module (231) and the motor (232). The motor (232) is configured to drive the transmission module (233) so as to drive the camera module (231) to move. The transmission module (233) defines at least one concave part (234) set on a lateral wall of the transmission module (233). Thus, an empty space may be formed above the concave part (234). In the electronic device (100), the empty space (26) may be utilized as the clearance area of the antenna radiator (27) inside the electronic device (100). Therefore, the performance of the antenna installed close to the camera module (231) may be improved.
