Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a resonator with high Q-factor is used to achieve narrow-band characteristics, then the filtering precision is improved, but the device complexity increases

Engineering Contradiction:
Improvefiltering precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The filter is divided into multiple resonators (first resonator, second resonator, third resonator, fourth resonator) with distinct functions. Each resonator handles specific frequency bands, allowing the system to achieve high filtering precision through distributed specialization rather than requiring a single complex high-Q resonator for all bands.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-plane resonator design to a three-dimensional laminated structure where resonators are stacked across multiple layers. This vertical dimensionality allows multiple resonators to coexist in a compact space, achieving narrow-band characteristics without proportionally increasing the device's footprint or complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If multiple resonators are used to achieve excellent intercepting characteristics, then the filtering performance is improved, but the device complexity increases

Engineering Contradiction:
Improveintercepting characteristicsVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple resonators are merged into a unified laminated structure where they share common support elements (first support, second support) and are interconnected through standardized coupling mechanisms. This integration allows the system to achieve excellent intercepting characteristics across multiple frequency bands while reducing overall structural complexity compared to separate resonator assemblies.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The resonators are designed with universal characteristics that allow them to serve multiple functions: each resonator can operate at different frequency bands, provide both narrow-band filtering and intercepting characteristics, and be integrated into the same laminated structure. This multi-functionality reduces the need for separate specialized components.

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

3Manufacturing precision

If a laminated structure with multiple conductive layers is used, then the manufacturing precision is improved, but the device complexity increases

Engineering Contradiction:
Improvelaminated structure precisionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The laminated structure is segmented into distinct conductive layers (first conductive layer, second conductive layer, third conductive layer, fourth conductive layer) that can be manufactured and positioned independently. Each layer serves a specific function and can be precision-manufactured separately before assembly, improving overall manufacturing precision while managing complexity through modular construction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Dielectric materials are introduced as intermediary elements between conductive layers, providing both electrical isolation and mechanical support. These intermediary dielectric layers simplify the manufacturing process by enabling independent positioning of conductive layers and reducing direct complexity in the conductive structure itself.

Inventive Principle:
Principle #24Intermediary (Mediator)
