Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety systems for unmanned flying objects cannot prevent their fall in the event of a failure, such as power or communication failures, and do not adequately protect the object or its equipment from damage during a fall, especially in populated areas.
Innovation Solution
A safety system comprising a wing support, mast, reel, retaining cable, and control station that deploys a wing and winds the cable to safely repatriate the flying object to a height above the ground, using sensors and communication means to detect failures and control the system's components to maintain stable altitude and minimize damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired system or parachute is used for safety, then the impact of fall is limited, but the fall cannot be prevented and damage to equipment occurs
Solution Approach 1:
The system performs preliminary actions by deploying the wing before any failure occurs. The control station continuously monitors flight parameters and pre-positions the wing in a ready state, so that when a failure is detected, the wing is already deployed and can immediately provide lift to prevent the fall, rather than reacting after the fall has begun.
Solution Approach 2:
The wing acts as an intermediary element between the failing flying object and the ground. Instead of allowing the object to fall directly to the ground causing damage, the wing provides an intermediate lifting force that redirects the object's motion, preventing impact with the ground and thereby protecting both the object and surrounding areas.
2Object-affected harmful factors
If the wing is deployed to prevent fall, then public safety is ensured, but the system complexity increases
Solution Approach 1:
The control station serves multiple functions: it monitors flight parameters, detects failures, controls the wing deployment, and manages the overall safety system. By consolidating these diverse functions into a single multi-functional control station, the system achieves public safety protection without proportionally increasing overall system complexity.
Solution Approach 2:
The system performs self-service through automatic failure detection and wing deployment. The control station continuously monitors flight parameters and automatically triggers wing deployment when a failure is detected, without requiring external intervention or complex manual control mechanisms, thereby simplifying the system's operational complexity while ensuring public safety.
3Productivity
If the retaining cable is wound quickly, then the flying object is repatriated fast, but damage to the object and equipment increases
Solution Approach 1:
The system applies dynamics by adjusting the winding speed of the retaining cable based on real-time conditions. The control station monitors the repatriation process and dynamically modulates the cable winding speed to optimize both speed and safety, preventing excessive forces that could damage the flying object or its equipment while maintaining efficient repatriation.

AI summary
The invention relates to a safety system for an unmanned flying object (1), flown by a user on the ground, the safety system making it possible to reduce the risks of the flying object (1) falling in the event of failure. The safety system comprises: a wing/sail/canopy support mounted on the flying object (1), a flexible wing/sail/canopy (2), such as a parachute, arranged on the wing/sail/canopy support; a winder (4) fixed in a flying-object (1) recovery zone (Z), the winder (4) including a winding drum and an electric motor for driving the drum; a retaining cable (5) connected by one of its ends to the flying object (1) and connected by its other end to the winding drum; and a control station (6) for, when failure in the flying-object (1) flight conditions is detected, commanding activation of the wing/sail/canopy support in order to deploy the flexible wing/sail/canopy (2) and commanding activation of the electric motor so as to turn the drum in such a way as to wind the retaining cable (5) onto the drum, the control station (6) also being programmed to vary the angular velocity at which the electric motor rotates.
