Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If functional components are exposed on the front surface, then user accessibility and functionality are improved, but the screen-to-body ratio is reduced and the device occupies more front surface space
Solution Approach 1:
The camera module transitions from a static exposed position to a dynamic retractable position. The module can be automatically ejected or manually pulled out from the housing cavity when needed, and retracted when not in use. This dynamic positioning allows the front surface to be fully available for display when the camera is retracted, while still providing easy access when extended.
Solution Approach 2:
The camera module is nested within the housing cavity when not in use, similar to a nested doll structure. The module fits inside the cavity space, allowing the front surface to be completely occupied by the display screen. When needed, the nested module can be extracted from the cavity for use.
2Adaptability or versatility
If functional components are exposed on the front surface, then functionality is improved, but the components become vulnerable to accidental impacts and damage
Solution Approach 1:
The housing cavity provides a protective enclosure for the camera module when it is retracted. This pre-established protective structure cushions the module from accidental impacts and environmental damage before any harmful event occurs. The module is safely housed within the cavity, protected from external forces.
Solution Approach 2:
The camera module can dynamically transition between exposed and retracted states based on usage conditions. When not in use, it automatically retracts into the protective cavity to avoid damage from accidental impacts. When needed, it extends for functionality. This dynamic response enhances both protection and usability.
3Ease of operation
If a mechanical driving structure is used to move the camera module, then the module can be extended and retracted, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical driving structures with alternative actuation methods. Instead of using motors, gears, or linkages to move the camera module, the invention employs magnetic fields or elastic elements to achieve extension and retraction. This substitution significantly reduces mechanical complexity while maintaining the desired functionality.
Solution Approach 2:
The camera module is designed to automatically extend and retract without requiring complex external driving mechanisms. Magnetic elements or elastic springs provide self-contained actuation forces that enable the module to move on its own in response to simple triggers or user input, eliminating the need for elaborate mechanical drive systems.

AI summary
The present disclosure provides a functional device. The functional device may include a frame, a driving assembly, and a sliding base. The frame defines a cavity. The driving assembly is received in the cavity. The driving assembly may include a motor, a lead screw, and a slider, the lead screw is connected to the rotating shaft of the motor, the slider is sleeved on the lead screw, the sliding base is slidably connected to the frame. The sliding base is slidably connected to the frame and has a magnetic attraction with the slider, configured to hold a functional component. When the rotating shaft drives the lead screw to rotate, the slider drives the sliding base to move relative to the frame to extend the functional component out of the frame or retract into the cavity. The present disclosure also provides a mobile terminal.
