Flying Object Nozzle Lid Prevents Liquid Dripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid dripping from discharge apparatuses mounted on flying objects, such as unmanned aerial vehicles, poses environmental and operational issues due to adhered material forming droplets, which can cause unwanted discharge and impact the surrounding environment.
Innovation Solution
A discharge apparatus with a lid that can open and close the nozzle, combined with a solidifying unit and receiving unit to absorb or solidify any dripped liquid, and a control method to manage the lid's operation during discharge and non-discharge states, preventing liquid from leaking or spilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid material is discharged from the nozzle, then the discharge function is improved, but liquid dripping occurs due to adhered material forming droplets
Solution Approach 1:
The lid is positioned in advance to cover the discharge port, and the opening/closing mechanism is pre-configured to automatically open the lid before discharge and close it after discharge, preventing liquid dripping before it can occur
Solution Approach 2:
The lid acts as an intermediary component between the liquid material and the external environment, controlling the discharge process and preventing direct contact between adhered material and the outside, thereby eliminating liquid dripping
2Object-generated harmful factors
If the nozzle is closed to prevent liquid dripping, then liquid dripping is prevented, but the discharge function is reduced
Solution Approach 1:
The lid is designed to be dynamically movable between open and closed positions, allowing the system to adapt its state based on discharge requirements - open during discharge for full functionality, closed during non-discharge for dripping prevention
Solution Approach 2:
The opening/closing mechanism is configured to automatically control the lid's position based on discharge status, eliminating the need for manual intervention and ensuring the lid is always in the correct state for the current operation
3Object-generated harmful factors
If a lid with opening and closing mechanism is added, then liquid dripping is prevented, but device complexity increases
Solution Approach 1:
The opening/closing mechanism is designed to operate automatically based on discharge status, eliminating the need for complex control systems or manual operation, thereby reducing overall device complexity while maintaining effective liquid dripping prevention
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
Effectively prevents liquid dripping by ensuring the nozzle is closed during non-discharge states and utilizing absorbent or solidifying mechanisms to handle any overflow, enhancing operational reliability and environmental safety.
Implementation Method 1
a lid that is capable of opening and closing a discharge port of the nozzle
Implementation Method 2
The lid is provided with an absorbent material that absorbs the liquid material at a position facing the discharge port when the lid is in a closed state
Implementation Method 3
a solidifying unit that receives and fixes the liquid material that has dripped from a discharge port of the discharge apparatus
Implementation Method 4
The lid rotates via a hinge to open and close the discharge port
Implementation Method 5
The lid is opened and closed by pressure generated when the liquid material is discharged
