Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional Cargo Bar is used, then the structure is simple and easy to manufacture, but the driver cannot remotely monitor the working state or detect loosening, posing safety hazards

Engineering Contradiction:

Improvesafety of cargo transportationVSAvoidstructure of Cargo Bar

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a feedback mechanism through the trigger assembly that detects the working state of the Cargo Bar and transmits signals to a terminal device, enabling remote monitoring and alerting the driver of any loosening or safety issues during cargo transportation

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces a signal transmitter as an intermediary component that bridges the physical Cargo Bar and the digital monitoring system, converting mechanical state changes into electrical signals that can be transmitted and monitored remotely

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If a Cargo Bar with monitoring function is added, then remote monitoring of working state is achieved, but the device complexity increases

Engineering Contradiction:

Improvemonitoring information of Cargo BarVSAvoidstructure of Cargo Bar

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The monitoring function is extracted as a separate trigger assembly that can be integrated into the existing Cargo Bar structure, rather than redesigning the entire system, thus minimizing the increase in overall device complexity while achieving remote monitoring capability

Inventive Principle:

Principle #2Taking out (Extraction)
