Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a common path configuration is used for transmission and reception wave paths, then the device complexity is reduced, but the loss and delay in transmission and reception increase

Engineering Contradiction:

Improvenumber of circulatorsVSAvoidloss in transmission wave path and reception wave path

Core Design Contradiction:

Device complexityVSLoss of energy

Solution Approach 1:

The waveguide unit is divided into separate transmission wave path and reception wave path sections. The transmission wave path includes a transmission wave input port and transmission wave output port, while the reception wave path includes a reception wave input port and reception wave output port. This segmentation allows independent optimization of each path, reducing the number of circulators needed while minimizing loss and delay in both paths.

Inventive Principle:

Principle #1Segmentation

2Productivity

If multiple transmission/reception processing units are added to a waveguide device, then the transmission capacity increases, but the flexibility and efficiency of adding units decreases

Engineering Contradiction:

Improvetransmission capacityVSAvoidflexibility of adding transmission/reception processing unit

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The waveguide unit is designed with universal interfaces that can connect to multiple transmission/reception processing units. The unit includes a transmission/reception processing unit connection, a transmission wave input port, a transmission wave output port, a reception wave input port, and a reception wave output port, allowing it to function as an intermediary between multiple processing units. This universal design enables flexible addition of units without requiring redesign of the entire system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the number of circulators in a waveguide device is increased, then the number of connectable transmission/reception units increases, but the loss and delay in wave paths increase

Engineering Contradiction:

Improvenumber of connectable transmission/reception unitsVSAvoiddelay in transmission wave path and reception wave path

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The invention extracts the reception wave path from the common path configuration and creates a separate reception wave input port and reception wave output port. This extraction eliminates the need for additional circulators that would be required to handle multiple units, while reducing the delay in the reception wave path by providing a dedicated path rather than sharing a common path with transmission.

Inventive Principle:

Principle #2Taking out (Extraction)
