Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a front camera is placed on the display surface to enable selfie function, then the camera can capture front-facing images, but the display area is reduced and full-screen design is compromised
Solution Approach 1:
The patent moves the camera function from the two-dimensional display surface to a three-dimensional sliding mechanism. The camera module can slide horizontally across the display surface and rotate vertically, utilizing spatial dimensions to achieve front-facing camera functionality without permanently occupying display area. This dimensional transition allows the camera to be positioned dynamically rather than statically on the screen.
Solution Approach 2:
The patent implements a dynamic camera system that can change its position and orientation. The camera module is mounted on a sliding mechanism that allows it to move horizontally across the display and rotate vertically to face forward. This dynamic positioning enables the camera to adapt between different functional states (selfie mode, rear camera mode, etc.) without compromising the display area when not in use.
2Area of stationary object
If periscope or slide camera types are used to hide the front camera, then full-screen design is achieved, but the body thickness increases and internal space is consumed
Solution Approach 1:
The patent divides the camera system into separate functional modules that can operate independently. The camera module is segmented from the main device body and mounted on a movable platform. This segmentation allows the camera to be positioned on the display surface when not in use, maintaining a thin profile, while providing full functionality when activated through the sliding and rotating mechanisms.
Solution Approach 2:
The patent creates a multi-functional camera system that can serve multiple purposes: front-facing selfie camera, rear camera, and potentially telephoto or wide-angle functions through the sliding mechanism. This universality allows a single camera module to replace what would traditionally require separate dedicated modules, reducing overall device thickness and internal space requirements.
3Area of stationary object
If slide type or slide cover type mechanisms are used, then front camera concealment is achieved, but assembly rigidity is poor and drop test performance is weak
Solution Approach 1:
The patent incorporates a rotating mechanism that allows the camera module to pivot vertically while maintaining its horizontal sliding position. This rotational capability provides structural stability by distributing mechanical stresses more evenly across the mounting structure, improving resistance to impact forces during drop tests while maintaining the full-screen design benefit.
Solution Approach 2:
The patent introduces an intermediary mounting structure that connects the camera module to the device body through a robust sliding and rotating mechanism. This intermediary structure acts as a mediator between the camera module and the main body, distributing mechanical loads and improving overall structural rigidity while maintaining the ability to conceal and expose the camera as needed.
4Adaptability or versatility
If traditional camera modules are used, then camera functionality is maintained, but internal space occupation is high and cost increases
Solution Approach 1:
The patent implements a nested structure where the camera module is mounted on a compact sliding platform that can be retracted into the device body when not in use. The rotating mechanism is nested within the sliding structure, allowing multiple functional elements to occupy the same spatial envelope. This nesting approach significantly reduces the internal space required compared to traditional fixed or protruding camera modules.
