Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If magnetic field sensors and coils are used to control driving stages and stopping, then vehicle control functions are achieved, but the driving behavior becomes abrupt and unnatural

Engineering Contradiction:

Improvevehicle controlVSAvoidnatural driving behavior

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the magnetic field-based control system with a wireless communication system using radio waves. Instead of using magnetic coils and sensors that cause abrupt control actions, the system uses wireless data transmission to convey control commands, enabling smooth and natural acceleration and braking behavior while maintaining all necessary control functions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless communication module as an intermediary between the control system and the vehicle. This mediator transmits control information wirelessly, avoiding the direct magnetic field interaction that causes abrupt control actions, thereby achieving natural driving behavior while maintaining effective vehicle control.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If magnetic field sensors and stop points are used for distance control and traffic simulation, then traffic control functions are achieved, but the hardware complexity and cabling requirements increase considerably
