Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If destructive methods are used to prevent unmanned vehicles from entering prohibited spaces, then the reliability of prohibited space protection is improved, but the harmful factors to the unmanned vehicle increase (causing damage)

Engineering Contradiction:

Improveprohibited space protectionVSAvoiddamage to unmanned vehicle

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary control system that communicates with the unmanned vehicle's existing control mechanisms. This intermediary approach allows the system to override or modify the vehicle's control signals to prevent entry into prohibited zones without using destructive force. The control system acts as a mediator between the vehicle operator and the vehicle's flight control, enabling non-destructive intervention.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces potential mechanical or physical destructive intervention methods with an electronic control system. Instead of using physical barriers, nets, or other mechanical means to stop the vehicle, the invention uses wireless communication and electronic signal processing to detect the vehicle's position and send control commands to alter its flight path, thereby substituting mechanical intervention with electronic control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If existing control systems of unmanned vehicles are overridden, then the ability to control the vehicle in prohibited spaces is improved, but the complexity of the control system increases

Engineering Contradiction:

Improvevehicle controlVSAvoidcontrol system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The control system is designed to work with multiple types of unmanned vehicles by interfacing with their existing control protocols and communication standards. Rather than requiring a completely new control system for each vehicle type, the invention uses universal communication interfaces and standardized protocols to override controls across different vehicle platforms, reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system establishes communication links and control protocols with the unmanned vehicle before the vehicle enters the prohibited zone. By setting up the control interface in advance and maintaining continuous communication, the system can smoothly transition to overriding controls when needed, rather than attempting to establish control under duress or during critical moments, which would increase complexity.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If a wireless transceiver with specific radiation pattern is used to detect unmanned vehicles, then the precision of detection within the spatial region is improved, but the device complexity increases

Engineering Contradiction:

Improvevehicle detection precisionVSAvoidtransceiver system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a wireless transceiver with a directional radiation pattern that concentrates detection energy in specific directions corresponding to the prohibited zone boundaries. Rather than using omnidirectional detection that would require more complex signal processing to determine direction, the directional antenna provides inherent spatial selectivity, improving detection precision for vehicles at zone boundaries without requiring additional complex detection equipment.

Inventive Principle:

Principle #3Local quality

AI summary

An unmanned vehicle interface device includes a wireless transceiver configured with a radiation pattern that covers a particular spatial region, and a controller coupled to the wireless transceiver. The controller is programmed to detect an unmanned vehicle within the particular spatial region using the wireless transceiver, upon detecting the unmanned vehicle, communicate with the unmanned vehicle using the wireless transceiver to override existing controls of the unmanned vehicle, and after overriding the existing controls, forcibly control the unmanned vehicle.
