Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If mmW antenna array is integrated with hinge structure, then space usage is optimized and device configuration flexibility is improved, but signal obstruction from hinge components increases
Solution Approach 1:
The hinge structure is divided into multiple segments including a first joint with attachment leaf and central leaf, and a second joint with attachment leaf and central leaf. The mmW antenna array is positioned in the shared plane formed by the central leaves, creating segmented zones where the antenna operates in a dedicated space between the attachment leaves, reducing signal blockage while maintaining compact integration.
Solution Approach 2:
The patent positions the mmW antenna array in a shared plane formed by the central leaves of the joints, utilizing the dimensional space between the attachment leaves. This spatial arrangement in three-dimensional hinge structure allows the antenna to operate in a zone that minimizes obstruction from the attachment leaves while maintaining compact device integration.
2Adaptability or versatility
If hinge structure is used for device configuration, then adaptability is improved, but mmW signal directionality and communication reliability deteriorate due to occlusion
Solution Approach 1:
The hinge structure enables dynamic adjustment of device configuration through rotational movement of the first and second joints, allowing the mmW antenna array to change its orientation and beam direction. This dynamic positioning capability maintains communication reliability by allowing the antenna to point toward the base station even as the device configuration changes, preventing persistent signal occlusion.
Solution Approach 2:
The hinge structure serves multiple functions: it provides mechanical configuration flexibility for the device while simultaneously serving as a mounting structure for the mmW antenna array. The shared plane formed by the central leaves creates a universal platform that supports both the mechanical articulation and the wireless communication functions.
3Device complexity
If mmW module is integrated with hinge, then device complexity is reduced, but heat management becomes more challenging due to confined space
Solution Approach 1:
The mmW module is integrated with the hinge structure, merging the mechanical articulation function and the wireless communication function into a single unified component. This integration reduces overall device complexity by eliminating separate mounting structures while the antenna array is positioned in the shared plane of the hinge to maintain thermal management effectiveness.
