Flight Device Collision Avoidance via Distance Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of unmanned flight devices, such as drones, increases, there is a growing need for safety measures to prevent collisions and ensure convenient operation, particularly in environments where multiple devices may be flying simultaneously.
Innovation Solution
A flight device and a structure that form a path with an evacuation space allow flight devices to determine if they are within a predetermined distance of another device and perform an avoidance action by changing their path to avoid collisions, using a combination of sensors and control systems to manage flight paths and prevent contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of flight devices is increased to expand applications, then productivity and application versatility are improved, but the risk of collision and safety hazards increase
Solution Approach 1:
The system performs preliminary determination of distance to other flight devices before collision occurs. The control device continuously monitors relative positions and predicts potential collision scenarios in advance, allowing the flight device to prepare avoidance maneuvers proactively rather than reactively.
Solution Approach 2:
The system implements continuous feedback through distance determination between flight devices. The control device receives real-time position information, calculates relative distances, and adjusts flight paths dynamically based on this feedback loop, enabling adaptive collision avoidance in crowded aerial environments.
2Reliability
If avoidance actions are performed frequently to prevent collisions, then safety is improved, but flight path stability and operation convenience deteriorate
Solution Approach 1:
The system dynamically adjusts avoidance actions based on real-time conditions. The control device determines whether avoidance is necessary by evaluating distance thresholds and relative motion vectors, performing path adjustments only when collision risk is actualized rather than continuously, thus maintaining flight stability while ensuring safety.
Solution Approach 2:
The system changes flight path parameters selectively based on determined distance conditions. When the distance to other flight devices exceeds safe thresholds, the original path is maintained; when thresholds are approached, path parameters are modified to execute avoidance maneuvers, optimizing the balance between safety and operational smoothness.
3Reliability
If distance determination and avoidance control systems are added to flight devices, then collision prevention capability is improved, but device complexity increases
Solution Approach 1:
The control device performs multiple functions using integrated processing: distance determination, collision risk assessment, path planning, and avoidance execution all occur within the same control system. This multi-functionality reduces overall system complexity compared to having separate dedicated systems for each function.
Solution Approach 2:
The flight device autonomously performs distance determination and avoidance maneuvers without requiring external intervention. The control device independently processes sensor data, determines collision risks, and executes avoidance actions, reducing the complexity of external control infrastructure needed.
