Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a solenoid-type antenna with loop pattern is formed using two layer patterns and a high permeability sheet, then the antenna can support various wireless communications, but the manufacturing process becomes complicated and production cost increases

Engineering Contradiction:

Improvewireless communication supportVSAvoidantenna assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the functions of multiple layers and high permeability sheets into a single integrated antenna structure. The single layer pattern integrates the radiating element and magnetic field concentration functions that were previously separated into multiple components, thereby reducing assembly complexity while maintaining wireless communication capabilities.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single layer pattern is designed to perform multiple functions simultaneously: it acts as both the radiating element for wireless communication and provides magnetic field concentration through its geometric design. This multi-functional design eliminates the need for separate high permeability sheets and multiple layers, resolving the contradiction between versatility and complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

Engineering Contradiction:

Improvewireless communication supportVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By merging the radiating pattern and magnetic field concentration functions into a single layer structure, the patent reduces the number of components that need to be manufactured, assembled, and quality-checked. This integration directly lowers production costs while maintaining the antenna's ability to support various wireless communications.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts and eliminates the high permeability sheet component from the traditional multi-layer design. By taking out this expensive and complex component while retaining its essential function through the single layer pattern's geometric design, the production cost is reduced without sacrificing wireless communication capabilities.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of manufacture

If a single layer pattern is used for the antenna, then the manufacturing cost is reduced and assembly structure is simplified, but the antenna must still effectively support various wireless communications

Engineering Contradiction:

Improvemanufacturing costVSAvoidwireless communication performance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The single layer pattern incorporates local variations in its geometric structure to optimize performance for different wireless communication frequencies and modes. By creating local quality variations in the pattern design, the antenna achieves reliable multi-band and multi-mode operation despite using a simplified single-layer structure, thus maintaining reliability while reducing manufacturing cost.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent utilizes parameter changes in the single layer pattern's geometric configuration to achieve different resonance frequencies and impedance characteristics required for various wireless communications. By carefully adjusting parameters such as trace width, spacing, and pattern geometry, the antenna maintains high reliability across multiple communication standards without requiring complex multi-layer structures.
