Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single UHF antenna is used in wearable articles, then the device complexity is low, but the communication reliability is reduced due to interference from human bodies

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidantenna system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the antenna system into multiple separate UHF antennas, each tuned to different frequencies. This segmentation allows each antenna to handle specific communication scenarios (through-body, around-body, or general communication), thereby improving overall communication reliability while managing complexity through functional specialization

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each antenna is tuned to different frequency ranges to optimize performance for specific communication paths. The first antenna is tuned for communication through the body, the second for communication around the body, creating localized optimization for different spatial regions and communication needs

Inventive Principle:
Principle #3Local quality

2Reliability

If multiple UHF antennas are incorporated for different communication scenarios, then the communication effectiveness is improved, but the device complexity increases

Engineering Contradiction:
Improvewireless communication effectivenessVSAvoidmultiple antenna system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The wearable article incorporates multiple UHF antennas that collectively provide universal communication coverage for various scenarios (through-body, around-body, and general communication). This multi-functionality ensures effective communication regardless of the wearer's position or the receiver's location, achieving universality in communication effectiveness

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

Solution Approach 2:

Each antenna is tuned to different frequency parameters within the UHF range. By changing the frequency parameter for different antennas, the system optimizes performance for different communication paths and scenarios, improving overall effectiveness while using standard UHF technology

Inventive Principle:
Principle #35Parameter changes

3Reliability

If antennas are tuned for specific communication paths (through body or around body), then the communication reliability for that path is improved, but the adaptability to different communication scenarios is reduced

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidcommunication scenario adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The antenna system is segmented into multiple specialized antennas, each optimized for specific communication paths (through-body or around-body). This segmentation provides reliability for each specific path while the collection of segmented antennas collectively covers multiple scenarios, achieving both specialization and adaptability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a composite antenna system combining multiple antennas with different frequency tunings. This composite structure integrates the strengths of individually tuned antennas, providing both specialized performance for specific paths and overall adaptability to various communication scenarios through the combined system

Inventive Principle:
Principle #40Composite materials
