Aerosol Discharge Buffer Mechanism for Stable UAV Valve Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing discharge mechanisms for aerosol containers in discharge apparatuses, particularly in unmanned aircraft, fail to effectively manage excess force, leading to potential damage and instability due to manufacturing variations and temperature changes.
Innovation Solution
A discharge apparatus with a buffer unit that includes a buffer elastic part to absorb excess force, combined with a discharge drive unit that converts rotational motion into linear motion, and a suppression mechanism to prevent excess force transmission, ensuring stable operation and component safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a discharge mechanism without buffer is used, then the structure is simpler, but excess force causes component damage and instability
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a buffer unit with a buffer elastic part that is pre-positioned to absorb excess force before it can damage components. The buffer unit is configured to elastically deform when excess force occurs, preventing transmission of damaging forces to the aerosol container and other components, thus ensuring reliability without significantly increasing structural complexity.
2Ease of manufacture
If manufacturing precision is relaxed, then production is easier, but temperature changes and variations cause instability
Solution Approach 1:
The patent applies parameter changes by using the buffer elastic part to dynamically adjust and absorb force variations caused by manufacturing tolerances and temperature changes. The elastic buffer transforms rigid force transmission into flexible force absorption, allowing the system to maintain stable discharge performance despite variations in manufacturing precision or environmental conditions.
3Device complexity
If no suppression mechanism is used, then the device is simpler, but excess force transmission damages components
Solution Approach 1:
The patent applies the intermediary principle by introducing a buffer unit as a mediating element between the discharge drive unit and the aerosol container. This intermediary buffer elastic part absorbs and dissipates excess force, preventing it from reaching and damaging the aerosol container and other components, thus protecting the system without requiring complex suppression mechanisms.

AI summary
Provided is a discharge apparatus to which an aerosol container can be detachably mounted, the discharge apparatus including: a pressing unit configured to press a stem for opening and closing a valve of the aerosol container; and a buffer unit configured to buffer excess force, which is an amount of force by which force with which the pressing unit presses the stem has exceeded force to open the valve. The buffer unit may be configured to buffer the excess force exerted on the pressing unit by moving the pressing unit according to the excess force. The buffer unit may be configured to buffer the excess force exerted on the aerosol container by moving the aerosol container according to the excess force.
