Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a measuring device is used for satellite reception systems, then measurement capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple measurement functions (voltage, current, frequency measurement, satellite position detection) into a single integrated measuring device that interfaces between the satellite receiver and LNB, eliminating the need for multiple separate measurement instruments and reducing overall system complexity
Solution Approach 2:
The measuring device performs multiple functions simultaneously: it measures electrical parameters (voltage, current, frequency), identifies satellite positions, displays signal strength, and provides diagnostic information, making it a universal tool for both installation and maintenance of satellite reception systems
2Ease of operation
If automatic satellite position evaluation is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The measuring device automatically evaluates satellite positions and displays signal strength without requiring user intervention or button pressing, making the device operate autonomously and simplifying the user interface to minimal interaction
Solution Approach 2:
The device provides continuous automatic feedback through LED displays showing satellite position identification and signal strength levels, enabling users to quickly assess alignment status without manual measurement steps
3Adaptability or versatility
If multiple measurement functions are integrated, then versatility is improved, but device complexity increases
Solution Approach 1:
