Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate signal lines are provided for each frequency band, then signal processing capability for multiple frequency bands is improved, but device complexity and mounting space increase

Engineering Contradiction:

Improvemulti-frequency band supportVSAvoidnumber of signal lines

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies a universal signal line that can handle multiple frequency bands through frequency-selective surface structures. The single antenna structure incorporates multiple frequency-selective surfaces that enable it to process different frequency bands simultaneously, eliminating the need for separate dedicated signal lines for each frequency band while maintaining multi-frequency band adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges multiple frequency band processing functions into a single antenna structure by integrating multiple frequency-selective surfaces. This consolidation combines what would traditionally require separate signal lines into one unified component, reducing overall device complexity while preserving the ability to handle multiple frequency bands.

Inventive Principle:

Principle #5Merging (Combining)

If multiple signal lines are used, then multi-frequency band capability is improved, but interference and operation errors increase

Engineering Contradiction:

Improvemulti-frequency band supportVSAvoidoperation stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the frequency bands using frequency-selective surfaces within the antenna structure. Each frequency band is handled through dedicated frequency-selective surfaces that are spatially separated, preventing interference between different frequency bands while maintaining the ability to process multiple bands simultaneously. This segmentation isolates signal paths and reduces operational errors.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The frequency-selective surfaces act as intermediaries between the input signal and the processing circuits for different frequency bands. These surfaces selectively pass specific frequency ranges while blocking others, serving as a mediator that prevents unwanted interference and ensures stable operation across multiple frequency bands without requiring multiple separate signal lines.

Inventive Principle:

Principle #24Intermediary (Mediator)
