Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wired drones face issues with socket damage and risk of injury or electrocution when falling from great heights, as well as limited protection for persons on the ground, due to repeated falls and potential electrical hazards.
Innovation Solution
A protective device for the connection between a wired drone and its power supply wire, featuring a remotely detachable socket with a non-conductive envelope, power supply cutoff, and mechanical shock protection systems such as energy-dissipating envelopes or parachutes, designed to prevent injury and electrocution by dissipating energy and slowing down the socket's fall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the socket is used for repeated detachable operations from great height, then the drone can perform emergency landings and monitoring missions, but the socket becomes damaged and the risk of injuring persons increases
Solution Approach 1:
The patent applies beforehand cushioning by equipping the socket with a parachute system that deploys before the socket reaches the ground during detachment. This pre-deployed cushioning mechanism absorbs the impact energy of the falling socket, preventing damage to the socket and eliminating the injury risk to persons on the ground. The parachute is prepared in advance and activates automatically when the socket is detached from the drone.
2Adaptability or versatility
If the socket falls from great height during detachment, then the drone can switch to autonomous battery flight, but the risk of electrocution of persons increases
Solution Approach 1:
The patent applies the taking out principle by extracting the electrical contacts from the socket and isolating them within an insulating envelope. This separation removes the hazardous electrical components from potential contact with persons during the detachment and fall process. The electrical contacts are taken out of the external environment and confined within a protective insulating structure, eliminating the electrocution risk while maintaining the drone's ability to switch to autonomous battery flight.
Solution Approach 2:
The patent uses an insulating envelope as an intermediary barrier between the electrical contacts and the external environment. This intermediary structure prevents direct contact between persons and the electrical components during socket detachment and fall. The insulating envelope acts as a mediator that allows the electrical system to function while protecting persons from electrocution risk.
3Reliability
If the socket is made robust to withstand repeated falls, then the socket can be reused after many falls, but the weight and complexity of the protective system increases
Solution Approach 1:
The patent applies segmentation by dividing the protective system into separate functional components: the socket itself, the parachute system, and the insulating envelope. This segmentation allows each component to perform its specific function independently - the socket handles electrical connection, the parachute handles impact absorption, and the envelope handles electrical isolation. This modular approach enables socket reusability after falls without requiring the entire system to be overly robust, thereby limiting the increase in overall complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for the reuse of the socket after multiple falls, reduces the risk of injury and electrocution, and ensures safe landing by disconnecting power supply and using energy-dissipating mechanisms to absorb shocks, thereby protecting persons and equipment.
Implementation Method 1
a system for slowing down the fall, such as a parachute

AI summary
The invention relates to a protection device for protecting the connection between a detachable wired drone (1) and the wire (5) thereof. This device enables the plug (3) to be reused even when it has fallen many times from a great height and limits the risk of injury and electrocution of people. The device consists of a non-conductive envelope surrounding the electrical contacts of the plug (3), a procedure or a mechanical system that cuts off the power when the plug (3) is detached from the drone (1), a system for mechanical protection against impacts, which can be an energy-dissipating envelope, a parachute-like system (4) for slowing down the fall, or the separation of the plug into a plurality of parts connected by a flexible element. The device according to the invention is particularly applicable to wired drones (1) in order to speed up movement outside the perimeter defined by the wire (5).
