Dip Coating Basin Covering Membrane for Evaporation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion treatment systems face challenges with temperature control, leading to increased evaporation and changes in the mixing ratio of the treatment medium, resulting in reduced process reliability and increased costs, while attempts to minimize basin opening restrict component handling.
Innovation Solution
A covering membrane system is used to cover the basin opening, with a separate storage and winding device for the membrane, allowing for minimal contact with the treatment medium and ensuring the full area is available for immersion treatment without obstructing component handling devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the basin opening is kept small to reduce evaporation and heat radiation, then temperature control costs are reduced, but component handling flexibility is restricted
Solution Approach 1:
The patent applies a dynamically movable cover that can be opened and closed as needed. The cover is not fixed but can be positioned flexibly to allow component handling when required, and closed when not in use to minimize evaporation and heat loss. This dynamic positioning resolves the contradiction between energy conservation and operational flexibility.
Solution Approach 2:
The patent uses a thin film cover made of flexible material that can conform to the basin opening and be easily moved. This flexible cover provides effective sealing for temperature control while allowing simple opening/closing operations, thus maintaining both energy efficiency and handling flexibility.
2Loss of substance
If a cover is placed over the basin opening to reduce evaporation, then treatment medium loss is reduced, but component handling is obstructed
Solution Approach 1:
The cover is designed as a movable component that can be opened to allow component immersion and closed afterward to prevent treatment medium loss. This dynamic operation enables both effective coverage for loss prevention and unobstructed access for handling operations.
Solution Approach 2:
The cover operates periodically - opened during component handling, closed during treatment processes. This periodic opening and closing allows the system to alternate between accessibility and coverage, resolving the contradiction between these two requirements.
3Loss of energy
If the basin opening is minimized to reduce heat radiation, then energy loss is reduced, but the usable pool area is significantly reduced
Solution Approach 1:
The cover is deployed only when not in use, allowing the full basin area to remain accessible during operations. This dynamic coverage approach minimizes heat radiation loss during idle periods without permanently reducing the usable pool area.
