Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaning apparatuses face challenges in efficiently drying workpieces due to rapid pressure reduction between the cleaning and drying chambers, which can lead to incomplete drying and increased chamber volume requirements.
Innovation Solution
A cleaning apparatus with a valve element and actuator mechanism that allows controlled communication between the cleaning and drying chambers, using a bellows connecting member to manage pressure and facilitate efficient vapor transfer, ensuring effective drying without increasing the apparatus's size or compromising condensation performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pressure inside the cleaning chamber is rapidly reduced by switching from non-communicating to communicating state, then the cleaning liquid vaporizes and moves to the drying chamber, but the chamber volume must be minimized to reliably dry the workpiece
Solution Approach 1:
The valve element is made movable relative to the workpiece, allowing dynamic adjustment of the valve position based on the workpiece size and shape. This enables the cleaning chamber volume to be adaptively optimized for different workpieces, improving drying efficiency while minimizing required chamber volume.
Solution Approach 2:
The invention changes the pressure parameter dynamically by rapidly switching between communicating and non-communicating states between cleaning and drying chambers. This pressure parameter change causes instantaneous vaporization of cleaning liquid and drives vapor transfer to the drying chamber, achieving efficient drying.
2Adaptability or versatility
If a valve element is positioned inside the cleaning chamber facing the first opening, then the opening-and-closing mechanism can switch between communicating and non-communicating states, but the valve element must be movable relative to the workpiece to accommodate different workpiece sizes
Solution Approach 1:
A supporting member is introduced as an intermediary component that slidably fits into the first opening and determines the valve element position. This supporting member simplifies the overall mechanism by providing a guided sliding structure, reducing complexity while maintaining adaptability to different workpiece sizes.
Solution Approach 2:
The valve element is designed to move dynamically relative to the workpiece, allowing the system to adapt to different workpiece sizes and shapes. This dynamic positioning capability enables versatile application without requiring complex adjustable mechanisms.
3Stress or pressure
If the connecting member is a bellows, then the pressure differences between chambers can be managed effectively, but the bellows must be positioned to allow valve element movement
Solution Approach 1:
A bellows is used as the connecting member between cleaning and drying chambers. The bellows is a flexible structure that can expand and contract to accommodate pressure differences and volume changes during the drying process, effectively managing pressure while maintaining a relatively simple configuration.
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
This configuration enables easier and faster drying of workpieces by managing pressure differences and vapor transfer efficiently, reducing the volume of the cleaning chamber needed and maintaining effective condensation performance.
Implementation Method 1
a connecting member (5) connecting a first opening (1c) provided in the cleaning chamber (1) and a second opening (4j) provided in the drying chamber (4); wherein the connecting member (5) is a bellows
Implementation Method 2
the pressure inside the cleaning chamber is rapidly reduced, and thereby the cleaning liquid adhering to the surface of the workpiece is vaporized. Since this rapid pressure reduction is performed when the cleaning chamber and the drying chamber are switched from a non-communicating state to a communicating state
Implementation Method 3
the pressure inside the cleaning chamber is rapidly reduced, and thereby the cleaning liquid adhering to the surface of the workpiece is vaporized
Implementation Method 4
the cleaning liquid adhering to the workpiece instantaneously vaporizes, and vapor moves from the cleaning chamber into the drying chamber and condenses thereat
Implementation Method 5
vapor moves from the cleaning chamber into the drying chamber and condenses thereat, whereby the drying of the workpiece is performed
