Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the communication device uses fixed frequency processing methods, then the device complexity is reduced, but the signal processing reliability deteriorates due to inability to adapt to different signal conditions

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic frequency tuning by allowing the communication device to adjust shift frequency and baseband frequency based on detected signal conditions. The processor determines optimal frequency parameters in real-time, enabling the system to adapt to varying signal environments rather than using fixed frequency processing methods.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the frequency parameters (shift frequency and baseband frequency) dynamically based on signal conditions. By detecting component radio frequency signals and their frequencies, the system adjusts these parameters to optimize signal processing reliability for different communication scenarios.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the communication device processes all frequency components, then the signal processing completeness is improved, but the power consumption increases

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent extracts and processes only the relevant frequency components by determining component radio frequency signals and their frequencies from the received signal. Instead of processing all frequency components uniformly, the system identifies and focuses computational resources on the specific frequency ranges that contain useful signal information.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies partial action by processing only the necessary frequency components rather than all frequency components. The system determines which frequency ranges contain signal content and processes those selectively, avoiding unnecessary computation on empty or irrelevant frequency bands.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If the communication device uses broad frequency processing, then the adaptability to different signals is improved, but the signal processing precision deteriorates

Engineering Contradiction:

Solution Approach 1:

The patent applies local quality by determining the specific frequency characteristics of component signals and tailoring the processing parameters to each detected signal's frequency range. The system adjusts shift frequency and baseband frequency based on the local frequency conditions of individual component signals, providing precise processing adapted to each signal's characteristics.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes processing parameters dynamically based on detected signal frequencies. By measuring the frequencies of component radio frequency signals and adjusting shift frequency and baseband frequency accordingly, the system maintains high processing precision while adapting to different signal types and frequency ranges.

Inventive Principle:
Principle #35Parameter changes
