VSEngineering Contradiction Analysis

1Productivity

If manual calculations are used to analyze signal characteristics, then the user can perform measurements, but the process is inefficient and time-consuming

Engineering Contradiction:
Improvemeasurement efficiencyVSAvoidtime for manual calculations
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The measurement application device automatically performs calculations and analysis of signal characteristics without requiring manual intervention. The computing device autonomously processes the measured signals, calculates differences between markers, and determines signal characteristics such as chirp rate, phase drift, and amplitude droop, enabling the system to serve itself rather than requiring user-performed manual calculations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical measurement and calculation processes with automated electronic computation. Instead of users manually reading values from diagrams and performing calculations, the computing device electronically processes signal data, automatically calculates differences between markers, and determines signal characteristics through computational algorithms

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If automatic calculation of signal characteristics is implemented, then measurement efficiency improves, but device complexity increases

Engineering Contradiction:
Improveautomatic measurement speedVSAvoidcomputing device functionality
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The measurement application device is designed with multi-functionality, where the computing device can perform various signal analysis tasks including calculating differences between markers, determining chirp rate, phase drift, and amplitude droop. This universal computing platform handles multiple measurement functions through a single integrated system rather than requiring separate dedicated devices for each function

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The computing device acts as an intermediary between the signal measurement function and the analysis function. It receives measured signals from the measurement function, processes them through computational algorithms, and outputs calculated signal characteristics. This intermediary processing layer integrates measurement and analysis functions without requiring direct complex interactions between all system components

Inventive Principle:
Principle #24Intermediary (Mediator)
