Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional antenna masts are deployed to increase bandwidth and connection density, then communication performance improves, but investment cost, space requirement, and landscape cluttering increase
Solution Approach 1:
The patent combines multiple antenna elements into a single integrated pipe structure, where multiple slots are formed on the surface of one elongated conductive pipe. This merging approach eliminates the need for multiple separate antenna masts while maintaining high connection density and bandwidth capabilities, directly resolving the contradiction between communication performance and device complexity
Solution Approach 2:
The conductive pipe serves multiple functions simultaneously: it acts as the radiating element for all antenna slots, provides mechanical support for the entire antenna array, offers environmental protection for internal components, and enables heat dissipation. This multi-functionality reduces the number of separate structures needed, addressing the contradiction between productivity and device complexity
2Adaptability or versatility
If flexible linear antenna arrays are used to enable distributed deployment, then deployment flexibility improves, but mechanical strength and robustness deteriorate
Solution Approach 1:
The patent employs a flexible printed circuit board (FPC) as the carrier for the antenna elements, allowing the entire antenna array to be bent and deployed in various configurations. The FPC maintains mechanical integrity while providing deployment flexibility, resolving the contradiction between adaptability and strength
Solution Approach 2:
The antenna array is divided into multiple independently controllable antenna elements formed as slots on the pipe surface. Each slot can be individually fed and controlled, allowing the system to be segmented into functional units that can be activated selectively. This segmentation provides deployment flexibility while the integrated pipe structure maintains overall mechanical strength
3Use of energy by moving object
If multiple antenna masts are deployed to reduce power consumption, then energy efficiency improves, but permission requirements and installation complexity increase
Solution Approach 1:
The patent merges multiple antenna functions into a single integrated structure that can be installed in one location. The elongated pipe containing multiple slots replaces what would traditionally require multiple separate mast installations, reducing permission requirements and installation complexity while maintaining the power efficiency benefits of multiple antenna elements
