Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lateral shift detection and compensation mechanisms are implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the radar system continuously monitors the positional accuracy of transmitting and receiving units by analyzing signal characteristics. When deviations from target positions are detected, the system generates control signals to displacement devices that automatically adjust the units back to their correct positions. This closed-loop feedback approach ensures high reliability without requiring overly complex manual intervention systems.
Solution Approach 2:
The radar system performs self-diagnosis and self-correction by autonomously detecting lateral shifts through signal analysis and automatically compensating for detected deviations. The system uses its own operational data to identify positioning errors and triggers corrective actions without external intervention, thereby maintaining reliability while avoiding the complexity of separate monitoring and control systems.
2Duration of action of stationary object
If continuous monitoring and compensation measures are implemented, then service life is extended, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the patent employs periodic detection cycles where the radar system analyzes signal characteristics at intervals to check for lateral shifts. Compensation actions are triggered only when deviations are detected, rather than operating continuously. This periodic approach extends service life through regular maintenance while significantly reducing energy consumption compared to continuous operation.
Solution Approach 2:
The system skips unnecessary monitoring and compensation operations by only activating detection and correction functions when actual deviations are detected. During normal operation with no positional errors, the system bypasses the energy-intensive monitoring and adjustment processes, thereby extending service life through adequate maintenance while minimizing energy consumption.
3Ease of operation
If automated control signals and displacement devices are added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The radar system automatically detects lateral shifts and generates control signals to displacement devices without requiring manual intervention. The system uses its own operational data to identify positioning errors and autonomously triggers corrective actions, making operation extremely easy while the added complexity is confined to the automated control system rather than user procedures.
Solution Approach 2:
The patent replaces manual mechanical adjustment procedures with automated electronic control signals that actuate displacement devices. Instead of requiring operators to physically reposition components, the system uses electronic sensing and control to automatically correct positioning errors, greatly simplifying operation while the complexity is managed through electronic rather than mechanical means.

AI summary
A computer device and a method for examining a radar system equipped with at least two transmitting and receiving units which each include at least one respective antenna element. The method includes: defining at least one probability distribution for at least one object with respect to a probable position of the respective object in an angular spectrum based on radar signals transmitted by the at least two transmitting and receiving units, reflected on the at least one object and received by the transmitting and receiving units, determining an average width of the probability distributions in the angular spectrum defined within a given time interval and within a given angular range of the angular spectrum, and defining position information relating to a displacement of at least one of the transmitting and receiving units out of its respective target position taking into account the determined average width.
