Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If hardware replacement is used for frequency switching, then frequency band change is achieved, but switching time increases and safety risks occur

Engineering Contradiction:

Improvefrequency band switching capabilityVSAvoidswitching time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical hardware replacement system with an electronic signal switching system. The switching unit (40) receives control signals electronically to switch between Ka band and Ku band frequency processing units (20, 30) without any physical component replacement, thereby eliminating the time-consuming mechanical replacement process while maintaining frequency band adaptability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a switching unit (40) as an intermediary component between the antenna unit (10) and the frequency processing units (20, 30). This switching unit acts as a mediator that can electronically route signals to different frequency processing units based on control signals, enabling fast frequency band switching without direct hardware replacement between the antenna and processing units

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If hardware replacement is used for frequency switching, then frequency band change is achieved, but safety hazards increase

3Reliability

If remote control switching is implemented, then operational safety improves and switching time decreases, but system complexity increases

Engineering Contradiction:

Improveoperational safetyVSAvoidcontrol system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the switching control functionality with the existing communication unit (60) of the satellite antenna system. The communication unit can receive control signals from external sources and transmit them to the switching unit (40), merging the control function into the existing system architecture rather than adding a completely separate control system, thus managing complexity while enabling remote operation

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The switching unit (40) is designed to autonomously switch between frequency processing units based on control signals without requiring manual intervention. The system performs the frequency band switching operation itself once triggered, eliminating the need for complex manual procedures and reducing operational complexity while maintaining safety

Inventive Principle:

Principle #25Self-service
