Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the embedded lens is disposed on the upper frame of the display, then the device structure is simplified, but the shooting angle and shooting range of the lens are limited
Solution Approach 1:
The patent applies the dynamics principle by making the camera rotatable around the third hinge axis, allowing the camera to dynamically adjust its shooting angle and direction. This rotational capability enables the camera to capture images from multiple angles without requiring the lens to be repositioned on the device structure, thus resolving the contradiction between structural simplicity and shooting versatility.
Solution Approach 2:
The patent introduces a new dimension of movement by allowing the camera to rotate around the third hinge axis, which is perpendicular to the plane of the first and second hinges. This adds a rotational degree of freedom that expands the shooting range from a fixed two-dimensional plane to a three-dimensional space, enabling the camera to capture images from various angles while maintaining the simple embedded lens structure.
2Adaptability or versatility
If the display angle is reduced to allow the lens to shoot a marker, then the lens can capture the marker, but the user experience is degraded due to non-ergonomic viewing angle
Solution Approach 1:
The patent resolves this contradiction by making the camera rotatable around the third hinge axis, allowing the camera to independently adjust its shooting angle without affecting the display angle. This dynamic adjustment capability enables the camera to capture markers at various angles while the display maintains its ergonomic angle for user viewing, thus achieving both marker shooting capability and user comfort simultaneously.
Solution Approach 2:
The patent applies segmentation by separating the camera's shooting function from the display's viewing function through the L-shaped hinge structure with three independent hinge axes. This segmentation allows the camera to rotate independently around the third hinge axis while the display maintains its angle relative to the keyboard base, enabling each component to optimize its function without compromising the other.
3Adaptability or versatility
If the L-shaped hinge allows 0 to 360 degrees flipping, then the device supports multiple usage modes, but the hinge structure becomes more complex
Solution Approach 1:
The patent achieves multiple usage modes through segmentation of the hinge structure into three independent parallel hinge axes (first, second, and third hinges) arranged in an L-shape. Each hinge axis provides independent rotational freedom, allowing the device to assume various configurations (clamshell, tent, tablet modes) without requiring a single complex universal joint. This segmented approach distributes the complexity across simpler, modular hinge components.
Solution Approach 2:
The L-shaped hinge structure with three perpendicular hinge axes introduces multi-dimensional rotational capability. The first and second hinges provide rotation in one plane, while the third hinge (perpendicular to the other two) enables rotation in a different plane, creating three-dimensional flexibility. This multi-dimensional hinge design allows the device to achieve various usage modes through combinations of rotations around different axes, rather than requiring a single complex mechanism.
