Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radar sensor devices use separate designs for transmission and reception paths, then functional reliability is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines the transmission path and reception path into a single integrated circuit chip, merging previously separate functional units. This integration reduces device complexity and manufacturing costs while maintaining functional reliability through careful architectural design that preserves the distinct operational modes of transmission and reception within the unified chip structure.
Solution Approach 2:
The integrated circuit chip is designed to perform multiple functions - both transmission and reception operations - within a single universal platform. This multi-functional design eliminates the need for separate dedicated hardware for each function, reducing overall system complexity while ensuring reliable operation of both transmission and reception paths through shared high-quality components and processes.
2Measurement precision
If radar systems use distributed antennas, then measurement precision is improved, but data load increases
Solution Approach 1:
The patent merges the data processing functions for multiple distributed antennas into a single integrated circuit chip. This consolidation allows the system to handle data from multiple antennas with high resolution while managing the overall data load efficiently within one unified processing unit, rather than requiring separate processing units for each antenna.
3Reliability
If multiple chip types are used for transmission and reception paths, then functional performance is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges transmission and reception path functionalities into a single chip type, eliminating the need to manufacture and assemble multiple different chip types. This unified approach reduces manufacturing complexity, assembly costs, and inventory requirements while maintaining high functional performance through integrated design that optimizes both transmission and reception capabilities within the same chip architecture.
