Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the parachute is deployed during flight, then the flight duration is extended and safe landing is achieved, but the propeller may collide with the parachute causing a crash

Engineering Contradiction:

Improvesafe landingVSAvoidpropeller-parachute collision

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary action by stopping the propeller before deploying the parachute. The controller detects parachute deployment and preemptively stops propeller rotation to eliminate the collision risk before it can occur, ensuring safe parachute deployment while maintaining flight duration extension capability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies preliminary anti-action by preventing the harmful collision through proactive propeller shutdown. When parachute deployment is detected, the controller immediately stops the propeller to counteract the potential collision hazard, transforming a dangerous situation into a safe landing sequence

Inventive Principle:

Principle #9Preliminary anti-action

2Productivity

If the propeller continues operating during parachute deployment, then the flight control responsiveness is maintained, but the collision risk increases leading to potential crashes

Engineering Contradiction:

Improveflight control responsivenessVSAvoidflight safety

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The controller performs preliminary action by stopping the propeller before parachute deployment occurs. This preemptive measure eliminates the collision risk while the parachute is being deployed, ensuring that safety is prioritized without compromising overall flight control responsiveness for other maneuvers

Inventive Principle:

Principle #10Preliminary action

3Duration of action of moving object

If the parachute is deployed to extend flight duration, then the operational capabilities are increased, but the propeller collision risk restricts the safe use of parachute

Engineering Contradiction:

Improveflight durationVSAvoidpropeller-parachute collision

Core Design Contradiction:

Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The system enables safe parachute deployment for flight duration extension by performing preliminary propeller shutdown when deployment is detected. This resolves the contradiction by eliminating the collision risk that would otherwise prevent parachute use, allowing flight duration to be extended safely

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system converts the potential harmful collision into a beneficial safe landing sequence. By stopping the propeller in response to parachute deployment detection, the harmful collision risk is transformed into a controlled descent scenario where the parachute successfully extends flight duration without accident

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

Provided is a method for controlling flight of a drone and an apparatus supporting the same. More specifically, the drone according to the present invention determines whether or not a specific condition is satisfied to deploy a parachute during the flight, and in a case where the specific condition is satisfied, the drone may stop an operation of one or more propellers to deploy the parachute. Next, the drone deploys the parachute, the parachute is deployed toward an area beside the drone, and the flight of the drone may be controlled by adjusting a rotation speed of each of the one or more propellers.
