Elongated Body Flying Object Vertical Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotary-wing aircraft equipped with working parts face instability and inefficiency due to balance issues when the working part is mounted close to the aircraft, affecting flight stability and the ability to approach targets closely without disturbing them, especially in narrow spaces or high altitudes.
Innovation Solution
A flying object design featuring a vertically elongated main body with a displaceable connection to the flight part, allowing the working part to be positioned at a safe distance from the main body while maintaining stability and enabling closer approach to targets, with the main body's length being at least twice the diameter of the flight part and featuring a balanced upper and lower structure for improved maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the working part is mounted close to the main body of the flying object, then the flight efficiency is improved, but the working part is affected by wind and sound generated from the flying object
Solution Approach 1:
The patent extends the mounting position of the working part from the horizontal dimension (close to main body) to the vertical dimension (below the flying object by a specific distance). This dimensional change allows the working part to be positioned in a region with less wind and sound interference while maintaining flight efficiency through proper vertical spacing.
Solution Approach 2:
The patent introduces a mounting structure with a specific vertical distance as an intermediary between the flying object and the working part. This intermediary spacing acts as a buffer zone that reduces the direct transmission of wind and sound from the flying object to the working part, thereby protecting the working part from harmful factors.
2Measurement precision
If the main body approaches the working target closely, then the working precision is improved, but the target may be disturbed by the posture and sound of the flying object
Solution Approach 1:
The patent segments the flying object system into two distinct parts: the flying object (main body with rotors) and the working part (camera or sensor). This segmentation allows the working part to be positioned separately below the flying object, enabling the main body to maintain a distance from the target while the working part performs precise measurements without disturbing the target with rotor noise and vibration.
Solution Approach 2:
The vertical spacing structure serves as an intermediary that decouples the flying object from the working part. This allows the working part to approach the target closely for high-precision work while the flying object remains at a safer distance, reducing the transmission of harmful factors like sound and vibration to the target.
3Device complexity
If the working part is mounted on the main body, then the device complexity is reduced, but the flying object may contact the target in narrow spaces
Solution Approach 1:
The patent positions the working part in the vertical dimension below the flying object rather than mounting it on the horizontal surface of the main body. This vertical arrangement allows the flying object to navigate narrow spaces more safely, as the working part extends downward away from potential contact points with the target, reducing collision risk while maintaining a simple mounting structure.
