Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate CPUs and power sources are used for radar and cellular systems, then functional independence and reliability are improved, but device complexity and resource demand increase
Solution Approach 1:
The patent combines the radar system and cellular system into a single integrated unit, sharing common components including CPU, power source, housing, and mounting structure. This merging reduces the number of separate components while maintaining both functional capabilities through modular subsystems that communicate via standardized interfaces.
Solution Approach 2:
The integrated system employs a universal CPU that handles both radar signal processing and cellular communications, and a single power source that supplies both subsystems. The shared housing and mounting structure provide universal mechanical support for both functions, reducing overall system complexity.
2Reliability
If separate CPUs and power sources are used for radar and cellular systems, then system reliability is improved, but weight and space requirements increase
Solution Approach 1:
By merging the radar and cellular systems into a single physical unit with shared components, the patent eliminates the weight of duplicate subsystems. The single CPU, power source, housing, and mounting structure reduce overall mass compared to having completely separate systems.
3Reliability
If separate CPUs and power sources are used for radar and cellular systems, then functional independence is improved, but ease of installation and maintenance deteriorate
Solution Approach 1:
The integrated design consolidates multiple installation tasks into a single mounting operation. The shared housing and mounting structure allow both radar and cellular subsystems to be installed together as one unit, reducing wiring harness complexity and simplifying the installation process.
Solution Approach 2:
Within the integrated system, the radar and cellular subsystems are segmented as modular components that can be independently developed, tested, and replaced. This segmentation maintains functional independence while simplifying maintenance and upgrades through standardized interfaces.
