Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If connectors and cables are used for high-speed data transmission between signal processing boards, then data transmission capability is achieved, but the device size and cost increase due to the large number of pins and complicated structure

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnector structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the connectors and cables from the signal transmission system. Instead of using traditional connectors with multiple pins and complex structures, the invention directly transmits millimeter wave signals through the dielectric member that couples the signal processing boards, thereby removing the problematic components while maintaining transmission functionality

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical connection system (connectors and cables with physical pins) with an electromagnetic field-based transmission system. The millimeter wave signals are transmitted through the dielectric member without requiring mechanical contact, thus substituting a mechanical system with an electromagnetic field system that is more reliable and less complex

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If connectors and cables are used for high-speed data transmission, then signal transmission is enabled, but vibration-induced disconnection occurs in vibration environments

Engineering Contradiction:
Improvedata transmission speedVSAvoidconnection stability under vibration
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces the mechanical connector system with an electromagnetic coupling system through the dielectric member. This substitution eliminates the mechanical contact points that are susceptible to vibration-induced disconnection, while maintaining high-speed data transmission capability through electromagnetic signal propagation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The dielectric member serves as an intermediary between the signal processing boards, providing a stable medium for electromagnetic signal transmission. This intermediary structure is not subject to the same vibration-induced failure modes as mechanical connectors, thereby improving connection stability in vibration environments while enabling high-speed transmission

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If adhesive hardening type high-dielectric resin is filled in connector to robust structure, then connector reliability is improved, but device size and cost increase

Engineering Contradiction:
Improveconnector structural strengthVSAvoidoverall device structure
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the entire connector structure from the system. Instead of reinforcing existing connectors with adhesive hardening resin, the invention removes the need for connectors altogether by using direct electromagnetic coupling through the dielectric member, thereby eliminating the source of structural complexity and cost

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The dielectric member acts as an intermediary that provides both mechanical support and electromagnetic transmission functionality. This single component replaces the complex connector assembly, simplifying the overall device structure while maintaining the necessary signal transmission capability

Inventive Principle:
Principle #24Intermediary (Mediator)
