VSEngineering Contradiction Analysis

1Productivity

If drones are used for tracking and monitoring individuals, then productivity and monitoring capability are improved, but reliability of maintaining continuous line-of-sight deteriorates in dynamic environments

Engineering Contradiction:
Improvemonitoring capabilityVSAvoidline-of-sight maintenance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system continuously receives location information from wearable devices and uses this feedback to dynamically adjust drone positioning. The computing platform processes real-time location data and sends control signals to move the drone toward individuals when line-of-sight is lost, creating a closed-loop control system that maintains reliable monitoring in dynamic environments.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The drone operates autonomously by receiving control signals based on processed location data without requiring constant manual intervention. The system automatically determines when line-of-sight is lost and directs the drone to reposition itself to restore visual contact, enabling self-correcting monitoring capability.

Inventive Principle:
Principle #25Self-service

2Reliability

If drones automatically adjust position to maintain line-of-sight, then reliability of line-of-sight maintenance is improved, but device complexity increases due to sensors and control systems

Engineering Contradiction:
Improveline-of-sight maintenanceVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A computing platform serves as an intermediary between the wearable devices and the drone control system. This centralized processor receives location data from multiple devices, determines which individuals require monitoring, and generates appropriate control signals, thereby simplifying the overall system architecture while maintaining reliable line-of-sight maintenance.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The control system is designed to handle multiple functions: receiving location data from various wearable devices, processing this information to determine monitoring priorities, generating control signals for drone positioning, and managing communication between components. This multi-functional approach reduces the need for separate specialized systems.

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

3Measurement precision

If multiple sensors and processing systems are added to ensure line-of-sight, then measurement precision of line-of-sight detection is improved, but device complexity increases

Engineering Contradiction:
Improveline-of-sight detection accuracyVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The computing platform acts as a central intermediary that receives and processes location information from wearable devices. By consolidating processing functions in a centralized system rather than distributing complex sensor arrays across multiple drones, the system achieves precise line-of-sight detection while minimizing overall device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Examples disclosed herein relate to control of a drone. In one example, aerial movement of the drone is controlled. In the example, it is determined, based on a plurality of devices, whether the drone is within a line- of-sight with at least a respective one of a plurality of humans within a physical proximity to a respective one of a the devices.. In the example, the devices are used by the drone to track the humans. In the example, when the drone is determined to lack the !ine-of-sight, aerial movement of the drone is controlled to move the drone to become within the line-of-sight.
