Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fixed-position antennas are used to control overall radiation pattern, then radiation pattern control is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent applies dynamics by making the radiation pattern adjustable through switchable reflection elements. Instead of using multiple fixed-position antennas, a single antenna structure is employed with reflection elements that can be dynamically activated or deactivated to change the radiation pattern. This allows the antenna to adapt between omnidirectional and directional patterns, reducing device complexity while maintaining versatility.
Solution Approach 2:
The patent implements universality by designing a single antenna structure that can perform multiple radiation patterns through the switchable reflection elements. The same antenna can produce omnidirectional radiation when all reflection elements are deactivated and directional radiation when specific reflection elements are activated, eliminating the need for multiple specialized antennas.
2Productivity
If conventional single polarization antenna is used, then device complexity is reduced, but signal transmission effectiveness deteriorates
Solution Approach 1:
The patent applies dynamics by enabling the antenna to dynamically switch between different polarization directions (horizontal and vertical) using switchable reflection elements. This dynamic polarization capability allows the antenna to adapt to different signal transmission requirements, improving signal transmission effectiveness without requiring multiple fixed polarization antennas.
Solution Approach 2:
The patent implements universality by designing a single antenna structure that can operate in both horizontal and vertical polarization modes. The switchable reflection elements enable the same antenna to provide dual polarization functionality, eliminating the need for separate antennas for different polarization directions and reducing overall device complexity.
3Productivity
If fixed omnidirectional radiation pattern is used, then device complexity is reduced, but signal performance and transmission speed deteriorate
Solution Approach 1:
The patent applies dynamics by enabling the radiation pattern to switch between omnidirectional and directional modes through the activation of switchable reflection elements. When directional transmission is required, specific reflection elements are activated to focus the radiation pattern, improving transmission speed and signal performance while maintaining the ability to revert to omnidirectional mode when needed.
