Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of antenna elements is increased to support evolving wireless communication technologies, then communication functionality and coverage are improved, but available space is reduced and coupling between antenna elements increases
Solution Approach 1:
The patent transitions from planar antenna arrangement to three-dimensional spatial arrangement. The first antenna element is positioned at a first location while the second antenna element is positioned at a second location that is offset in both position and orientation, utilizing vertical and lateral dimensions to achieve spatial separation without increasing the device's footprint area.
Solution Approach 2:
The patent integrates multiple antenna elements within a compact housing structure, nesting the antenna elements and their supporting structures within the device's internal volume. The first and second antenna elements are accommodated within the housing at different spatial locations, effectively utilizing the available three-dimensional space.
2Adaptability or versatility
If the number of antenna elements is increased, then wireless communication capability is improved, but coupling between antenna elements increases affecting antenna performance
Solution Approach 1:
The patent employs asymmetric positioning and orientation of antenna elements. The first antenna element has a first orientation while the second antenna element has a second orientation that is different from the first, creating asymmetric spatial relationships that reduce mutual coupling and improve overall antenna system performance.
Solution Approach 2:
By introducing vertical and lateral offsets between antenna elements, the patent utilizes three-dimensional spatial separation to reduce electromagnetic coupling. The second antenna element is positioned not only at a different horizontal location but also at a different vertical level and with a different orientation angle, effectively isolating the electromagnetic fields.
3Volume of moving object
If the distance between antenna elements is reduced due to limited space, then device compactness is improved, but coupling with electronic components increases
Solution Approach 1:
The patent assigns different orientations and positions to different antenna elements based on their specific functional requirements and spatial constraints. The first antenna element is positioned and oriented for optimal performance in one direction, while the second antenna element is positioned and oriented differently to minimize coupling with nearby electronic components and to complement the first element's coverage.
