Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a conventional radio wave reflective structure is used, then the structure is simple, but the phase characteristics become nonlinear and performance degrades over wide frequency bands

Engineering Contradiction:
Improvestructure complexityVSAvoidphase characteristic consistency
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The reflective plate is divided into multiple unit structures, each containing resonators that can be independently designed and optimized. This segmentation allows each unit to contribute to linear phase characteristics across different frequency ranges, collectively achieving wideband linear phase response while maintaining structural simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The resonant frequency and coupling characteristics of the resonators are adjusted by changing geometric parameters such as resonator dimensions, spacing, and coupling conductor configurations. This enables optimization of phase characteristics across wide frequency bands while maintaining a relatively simple overall structure

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the resonator parameters are optimized for a specific frequency, then the performance at that frequency is improved, but the performance degrades over wide frequency bands

Engineering Contradiction:
Improveresonator parameter precisionVSAvoidfrequency band coverage
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The unit structures are designed to perform multiple functions: each resonator serves both as a phase control element and as a frequency-selective element. The coupling conductors provide both magnetic and capacitive coupling mechanisms, enabling the same structure to operate effectively across wide frequency bands with linear phase characteristics

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

Solution Approach 2:

The reflective plate employs a composite structure combining multiple resonator types and coupling mechanisms within unit structures. This composite approach enables the system to maintain precise resonator parameters for specific frequencies while achieving broad frequency band coverage through the collective response of multiple resonant modes

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If multiple resonators are connected with complex coupling structures, then the frequency adjustment capability is improved, but the device complexity increases

Engineering Contradiction:
Improvefrequency adjustment capabilityVSAvoidcoupling structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The coupling function is extracted into separate coupling conductors that are distinct from the resonators themselves. This separation allows independent optimization of resonator parameters for frequency control while keeping coupling structures simple and standardized, reducing overall device complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The coupling conductors act as intermediary elements between resonators, providing controlled magnetic and capacitive coupling. This intermediary approach enables frequency adjustment through simple geometric modifications of the coupling conductors rather than complex reconfiguration of the entire resonator system

Inventive Principle:
Principle #24Intermediary (Mediator)
