Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display area is expanded to provide larger screen real estate, then user experience and visual capabilities are improved, but the space available for accommodating antennas and other electronic components decreases
Solution Approach 1:
The patent moves the antenna from the traditional planar layout within the display area to a three-dimensional configuration using a rotational shaft structure. The antenna is positioned on the rotational shaft that extends perpendicular to the display plane, utilizing the Z-axis dimension to resolve the spatial conflict between display area and antenna accommodation space.
Solution Approach 2:
The rotational shaft acts as an intermediary structure that carries the antenna away from the display area while maintaining electrical connection. This mediator element enables the antenna to be positioned in a location that does not interfere with the display while still fulfilling its electromagnetic radiation function.
2Adaptability or versatility
If more electronic components and functionality are integrated into the device, then device capability and functionality are improved, but the device size and form factor increase
Solution Approach 1:
The patent employs a rotational shaft that enables dynamic adjustment of the antenna position and orientation. This dynamic structure allows the antenna to be positioned optimally for different functional requirements without permanently increasing the device's form factor, as the antenna can be rotated into compact configurations when not in use.
Solution Approach 2:
The antenna is nested within or on the rotational shaft structure, which itself is integrated into the device's existing mechanical framework. This nesting approach allows the antenna system to occupy minimal space while providing full antenna functionality, enabling increased electronic capability without proportional increase in device volume.
3Device complexity
If the antenna is positioned closer to the display area to simplify structure, then manufacturing complexity is reduced, but signal quality and antenna performance deteriorate
Solution Approach 1:
The rotational shaft serves as an intermediary that maintains electrical connection between the antenna and the display while physically separating them. This mediator structure allows the antenna to be positioned at an optimal distance for signal quality while still being connected to the display's electronic components through the rotational shaft's conductive elements.
