Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If satellite navigation systems are used for drone delivery, then navigation coverage is improved, but navigation precision deteriorates due to signal distortion and selective availability

Engineering Contradiction:
Improvenavigation coverageVSAvoidnavigation precision
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The patent introduces a local reference station as an intermediary between the satellite navigation system and the drone. This reference station receives satellite signals, determines its precise position through multiple satellite measurements, and transmits correction data to drones in its coverage area. The correction data compensates for signal distortions and selective availability effects, enabling precise navigation while maintaining wide coverage through the reference station's local correction zone

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback by having the reference station continuously monitor satellite navigation signals and compute correction values based on its known precise position. These correction values are fed back to drones in real-time, allowing them to compensate for navigation errors. The feedback loop ensures that even when satellite signals are distorted or selectively degraded, drones can maintain accurate positioning within the reference station's coverage area

Inventive Principle:
Principle #23Feedback

2Productivity

If fully automated drone delivery is implemented, then delivery efficiency is improved, but security against misuse and theft deteriorates

Engineering Contradiction:
Improvedelivery efficiencyVSAvoidsecurity against misuse
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by establishing a secure authentication protocol before the drone approaches the delivery location. The reference station and drone exchange cryptographic credentials in advance, and the receiving device verifies the drone's authorization before accepting the package. This preliminary security check prevents unauthorized drones from intercepting or stealing packages, maintaining security while enabling fully automated delivery operations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements preliminary anti-action by having the reference station transmit authentication data and security credentials to the drone before the delivery operation begins. The receiving device is pre-configured with authorization verification mechanisms that actively prevent unauthorized access. This preliminary protective measure counteracts potential security threats before they can manifest, allowing automated delivery to proceed securely

Inventive Principle:
Principle #9Preliminary anti-action

3Measurement precision

If precise geo-coordinates are used for delivery locations, then delivery precision is improved, but vulnerability to address falsification increases

Engineering Contradiction:
Improvedelivery precisionVSAvoidaddress falsification risk
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces the reference station as an intermediary that verifies delivery locations. Instead of directly trusting geo-coordinates provided by the drone or receiver, the reference station independently determines its precise position through satellite navigation and compares it with the expected delivery location. This intermediary verification prevents address falsification while maintaining the precision benefits of geo-coordinate-based delivery

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses feedback by having the reference station continuously monitor and verify the actual delivery location against the intended coordinates. If there is a discrepancy indicating potential address falsification, the reference station can alert the system and prevent the delivery. This feedback mechanism maintains delivery precision while protecting against coordinate manipulation

Inventive Principle:
Principle #23Feedback

4Reliability

If cryptographic authentication is implemented for drone-receiver communication, then security is improved, but device complexity increases

Engineering Contradiction:
Improveauthentication securityVSAvoidcommunication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical or hardware-based authentication systems with electronic cryptographic methods. Instead of using physical keys, cards, or biometric devices, the system uses software-based cryptographic protocols that can be implemented in the drone's flight controller and the receiving device's microcontroller. This substitution maintains high security while reducing mechanical complexity and enabling fully automated operation

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

Solution Approach 2:

The cryptographic authentication system is designed to be universal and multi-functional, serving both security authentication and identification purposes. The same cryptographic credentials used for authentication also identify the drone and receiver to each other, eliminating the need for separate identification mechanisms. This universality reduces overall system complexity while maintaining strong security

Inventive Principle:
Principle #6Universality (Multi-functionality)
