Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles with rotary wings experience instability when ascending and descending in passage spaces due to air pressure differences caused by air conditioning or other environmental factors, leading to increased energy consumption and reduced flight efficiency.
Innovation Solution
An operation facility with a passage space extending in the up-down direction equipped with an air pressure control system that maintains a lower air pressure above the unmanned aerial vehicle than below it, using an air discharge unit and an air supply unit to manage air pressure and stabilize flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the unmanned aerial vehicle ascends and descends in a passage space with conventional air pressure control, then the passage space can be used for vertical transport, but the flight becomes unstable due to air pressure differences caused by air conditioning or environmental factors
Solution Approach 1:
The patent applies parameter changes by actively controlling air pressure in the passage space to create a pressure gradient where pressure above the unmanned aerial vehicle is lower than pressure below it. This parameter change in air pressure distribution provides a stabilizing force that counteracts flight instability, allowing the vehicle to maintain stable flight during vertical movement through the passage space.
2Use of energy by moving object
If the unmanned aerial vehicle operates in a passage space without air pressure control, then the system is simpler, but energy consumption increases due to the need for additional lift force to overcome unstable air pressure conditions
Solution Approach 1:
By changing the air pressure parameter in the passage space to create a pressure gradient, the system reduces the energy consumption of the unmanned aerial vehicle. The pressure difference generates a stabilizing force that assists the vehicle's lift, reducing the power needed from the vehicle's propulsion system to maintain stable flight during vertical transport.
3Reliability
If air pressure in the passage space is not controlled, then the air conditioning system is simpler, but flight stability deteriorates due to air pressure differences from environmental factors
Solution Approach 1:
The patent implements parameter changes by using the air conditioning system to actively control and maintain a specific air pressure gradient in the passage space. This controlled pressure distribution, where pressure above the vehicle is lower than pressure below it, stabilizes flight while the energy cost is managed through efficient pressure control rather than temperature control alone.
