Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If infrastructure uses wired network connection for data transmission, then communication reliability is improved, but installation complexity and cost increase due to cable requirements

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidinstallation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical cable connection system with an electromagnetic wireless communication system. Vehicles equipped with communication devices transmit data wirelessly to infrastructure, eliminating the need for physical cable installation while maintaining communication reliability through RF modules and processors.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The vehicle acts as an intermediary carrier between infrastructure points. Instead of directly connecting infrastructure A to infrastructure B via cable, the system uses vehicles that pass through the area to carry and transmit data, simplifying the installation by removing cable requirements while maintaining data transmission capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Area of stationary object

If infrastructure increases coverage area for data transmission, then service range is improved, but infrastructure cost increases due to additional stations or cable installation

Engineering Contradiction:

Improvecoverage areaVSAvoidinfrastructure cost

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The system utilizes vehicles that already exist and move through the area as self-service data carriers. Instead of installing additional infrastructure stations to expand coverage, the system leverages the natural movement of vehicles to extend the effective coverage area of existing infrastructure points.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Vehicles serve multiple functions: they are both transportation carriers and data transmission media. This multi-functionality allows existing vehicles to extend infrastructure coverage without requiring additional dedicated infrastructure installations, thereby expanding service range without proportionally increasing infrastructure costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If infrastructure requires physical cable connection for data transmission, then communication stability is improved, but adaptability to different locations deteriorates

Engineering Contradiction:

Improvecommunication stabilityVSAvoidlocation adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system transitions from a static cable-based connection to a dynamic wireless communication system. Vehicles move dynamically through different locations, providing adaptable data transmission to various infrastructure points without requiring fixed cable installations, thereby improving location adaptability while maintaining communication stability through reliable wireless protocols.

Inventive Principle:

Principle #15Dynamics

4Reliability

If vehicle selects multiple neighbors for data transmission, then transmission reliability is improved, but communication complexity increases

Engineering Contradiction:

Improvetransmission reliabilityVSAvoidcommunication complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The infrastructure point broadcasts data requests and receives responses from multiple neighbor vehicles. The system uses feedback mechanisms to identify which vehicles have successfully received or can transmit data, allowing the infrastructure to select appropriate vehicles dynamically. This feedback-based selection process improves transmission reliability through multiple potential carriers while managing communication complexity through structured request-response protocols.

Inventive Principle:

Principle #23Feedback
