Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing discharge apparatus for aerial vehicles face challenges in efficiently mounting aerosol containers, managing multiple containers, and simplifying control methods due to space constraints and weight considerations, particularly when equipped with cameras and direction-changing devices.
Innovation Solution
The apparatus mounts aerosol containers outside the airframe, connects them to nozzles via tubes, and uses a common direction-changing device for both the camera and nozzle, allowing for synchronization and simplifying control while optimizing space usage and weight balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the aerosol container is mounted inside the airframe, then the discharge apparatus can be integrated with the aerial vehicle structure, but the airframe must be significantly modified and the shape and size of the airframe are restricted
Solution Approach 1:
The aerosol container is extracted from the interior mounting location and relocated to the exterior of the airframe. This allows the airframe to maintain its original shape and size without modifications, while the container can be freely positioned outside using mounting brackets or other external fixation methods.
2Adaptability or versatility
If the aerosol container is mounted on the outside of the airframe, then the airframe shape and size are not restricted, but it is difficult to secure space particularly when a camera is mounted
Solution Approach 1:
The aerosol container is positioned in the lateral direction (width dimension) of the aerial vehicle rather than extending forward or backward. This utilizes the lateral space that would otherwise be unused, allowing the container to be mounted without interfering with the camera's forward-facing position or the airframe's length.
3Device complexity
If only one aerosol container is equipped, then the device structure is simple, but the work must be stopped and the aerial vehicle must return when the container is emptied
Solution Approach 1:
The single aerosol container system is segmented into multiple separate containers. Each container operates independently and can be positioned at different locations on the aerial vehicle. When one container is emptied, the others remain available for continued operation, eliminating the need to stop work and return for refilling.
4Productivity
If a plurality of aerosol containers are mounted, then work efficiency is increased, but there is no space for mounting multiple containers in the airframe
Solution Approach 1:
Multiple aerosol containers are arranged in the lateral direction (width dimension) rather than stacking them in the vertical or longitudinal directions. This充分利用 utilizes the lateral space of the aerial vehicle, allowing multiple containers to be mounted side-by-side without increasing the vehicle's length or height, thus accommodating multiple containers within the available space envelope.
5Ease of operation
If separate direction changing devices are provided for the camera and nozzle, then each can be independently controlled, but the entire weight is increased and the control method becomes complicated
Solution Approach 1:
The camera and nozzle are merged into a single integrated assembly that shares a common direction-changing device. This single device simultaneously adjusts the orientation of both the camera and the nozzle, reducing the total weight compared to having separate devices. The control method is simplified to a single control system that manages the unified assembly's direction.

Function Achieved in This Case
This configuration enables efficient use of external space for aerosol containers, allows for multiple containers without interrupting operation when one is empty, and simplifies control methods by integrating camera and nozzle direction changes, enhancing work efficiency and reducing weight.

AI summary
A discharge apparatus for an aerial vehicle is provided which is capable of mounting an aerosol container by effectively utilizing a space outside an airframe.The discharge apparatus for an aerial vehicle, in which a content is discharged through a nozzle from an aerosol container mounted on an airframe, is characterized in that the aerosol container is mounted outside the airframe, and is arranged so that a central axis of the aerosol container is along a pitch axis of the airframe, or arranged on an extension portion such as a small wing extending from a fuselage of the airframe, an arm portion provided with a rotor blade, a leg portion for taking off and landing, or the like, with the aerosol container and the nozzle being connected to each other through a tube.
