Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna is used for both transmission and reception (monostatic architecture), then device complexity is reduced, but measurement precision and reliability deteriorate due to the need for extremely precise synchronization between transmitter and receiver
Solution Approach 1:
The patent divides the monostatic radar system into multiple distributed satellites, each functioning as an independent transceiver unit. This segmentation eliminates the need for precise synchronization between separate transmitter and receiver components, as each satellite operates autonomously while contributing to the collective imaging function.
Solution Approach 2:
The patent introduces a distributed network architecture where multiple satellites act as intermediaries between the target scene and the final image product. Each satellite receives and processes signals independently, then combines their contributions through networked data fusion, eliminating the direct synchronization requirement between transmitter and receiver.
2Area of stationary object
If different configurations of antennae are used to increase coverage area, then area coverage is improved, but device complexity increases
Solution Approach 1:
The patent segments the coverage area requirement across multiple identical satellite units, each with standardized antenna configurations. Instead of designing different antenna systems for different coverage needs, the same modular satellite design can be deployed in varying numbers to achieve different coverage areas, simplifying the design process while maintaining scalability.
3Productivity
If different configurations of antennae are used to increase coverage speed, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent divides the coverage speed requirement across multiple parallel satellite operations rather than relying on complex single-antenna configurations. Each satellite operates independently at standardized speed, and the collective throughput achieves high coverage speed through parallel processing and distributed data collection.
4Measurement precision
If different configurations of antennae are used to increase image quality, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the image quality enhancement function across multiple satellites with identical, standardized antenna configurations. Instead of using complex single-antenna systems, each satellite contributes to the final image quality through its standardized antenna, with overall image quality improved through the combined data from multiple units rather than individual complexity.
