Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is disposed around the screen to avoid signal interference, then wireless communication reliability is improved, but the display area is reduced and aesthetic appearance deteriorates
Solution Approach 1:
The antenna is relocated from the traditional screen border area to the hinge structure, utilizing a different spatial dimension. The hinge serves as a new carrier space for the antenna, allowing wireless communication functionality to be maintained while preserving the full display area and achieving a borderless display appearance.
Solution Approach 2:
The hinge acts as an intermediary structure that hosts the antenna, separating the antenna from both the screen area and the main body electrical components. This intermediary positioning allows the antenna to maintain adequate distance from potential sources of electromagnetic interference while occupying space that does not interfere with the display area.
2Reliability
If the antenna is disposed around the screen to avoid signal interference, then wireless communication reliability is improved, but the aesthetic appearance deteriorates due to border obstruction
Solution Approach 1:
The antenna is relocated from the traditional screen border area to the hinge structure, utilizing a different spatial dimension. The hinge serves as a new carrier space for the antenna, allowing wireless communication functionality to be maintained while preserving the full display area and achieving a borderless display appearance.
3Shape
If the display is made narrow or borderless to improve aesthetic appearance, then aesthetic appearance is improved, but space for antenna integration is reduced
Solution Approach 1:
The hinge is designed to serve multiple functions: it provides the mechanical connection between the screen and keyboard, enables screen rotation and adjustment, and simultaneously serves as a carrier for the antenna. This multi-functionality allows the hinge to accommodate wireless communication components without requiring additional dedicated space, thus supporting borderless display design.
4Productivity
If electrical components are placed in the computer host to improve functionality, then hardware performance is improved, but electromagnetic interference with the antenna increases
Solution Approach 1:
The antenna is extracted from the traditional locations near electrical components and relocated to the hinge structure. This separation removes the antenna from the high electromagnetic interference environment created by electrical components in the computer host, while the hinge's plastic material provides additional electromagnetic shielding.
Solution Approach 2:
The hinge acts as an intermediary structure that hosts the antenna, separating the antenna from both the screen area and the main body electrical components. This intermediary positioning allows the antenna to maintain adequate distance from potential sources of electromagnetic interference while occupying space that does not interfere with the display area.
