Engineering Contradiction Analysis
1Measurement precision
If a dynamic signal analyzer (DSA) is used to measure dynamic characteristics of the system, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent creates a simplified copy of the DSA functionality by implementing a signal analysis circuit that replicates the essential measurement capabilities using basic electronic components (operational amplifiers, resistors, capacitors) instead of expensive commercial DSA equipment, thereby reducing device complexity while maintaining measurement precision
Solution Approach 2:
The patent replaces expensive, complex DSA equipment with inexpensive, simple electronic components that can be easily manufactured and disposed of, significantly reducing the cost and complexity of the measurement system while achieving the same functional goal
2Measurement precision
If a dynamic signal analyzer (DSA) is used to measure dynamic characteristics of the system, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive DSA equipment with inexpensive electronic components (operational amplifiers, resistors, capacitors) that are cheap to manufacture and purchase, dramatically reducing the manufacturing cost while maintaining measurement precision through careful circuit design
Solution Approach 2:
The patent creates a low-cost replica of DSA functionality using standard electronic components that are widely available and inexpensive, achieving the same measurement precision at a fraction of the manufacturing cost of commercial DSA equipment
3Measurement precision
If a dynamic signal analyzer (DSA) is used to measure dynamic characteristics of the system, then measurement precision is improved, but ease of operation worsens
Solution Approach 1:
The signal analysis circuit automatically performs measurement and analysis functions without requiring complex external equipment or sophisticated operating procedures, making the system easier to operate while maintaining measurement precision through self-contained functionality
Solution Approach 2:
The patent combines the signal generation, signal analysis, and measurement functions into a single integrated circuit, eliminating the need for separate complex equipment and simplifying the operation while maintaining measurement precision
