Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a single antenna module is used in limited space, then device size is reduced, but transmission power and signal coverage deteriorate
Solution Approach 1:
The antenna system is divided into multiple antenna modules, each with distinct feed point configurations. This segmentation allows each module to contribute to the overall transmission power while maintaining a compact device form factor, resolving the contradiction between small size and high power output.
Solution Approach 2:
Multiple antenna modules are combined to form an antenna array that achieves doubled Effective Isotropic Radiated Power (EIRP). The merging of multiple modules' contributions enables high transmission power and wide signal coverage within limited device space.
2Volume of moving object
If antenna space is limited, then device compactness is improved, but communication radius and signal coverage deteriorate
Solution Approach 1:
The patent transitions from a single antenna module to a multi-module array configuration, effectively utilizing spatial dimensions within the device. This dimensional expansion enables wider beam coverage and extended communication radius without increasing the device's external dimensions.
3Power
If multiple antenna modules are used to increase power, then transmission power is improved, but device complexity increases
Solution Approach 1:
Each antenna module is designed with universal functionality to support multiple frequency bands and dual polarization. This multi-functionality reduces overall system complexity by using standardized modules rather than requiring different specialized components for each function.
Solution Approach 2:
The patent utilizes parameter changes in feed point configurations across different antenna modules to achieve doubled EIRP. By varying the number and arrangement of feed points rather than changing the fundamental module structure, the system achieves higher power with minimal increase in complexity.
