Solution Overview
Problem
Existing decoating systems require a significant amount of time to remove surface layers from coated workpieces due to inefficient mechanical and chemical detachment processes.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional decoating systems are used, then the decoating process can be carried out, but the time required for removing surfaces is considerable
Solution Approach 1:
The decoating tank is divided into multiple zones with different dosing tubes arranged at various positions (bottom, sides, top) to create segmented turbulence patterns. Each dosing tube introduces fluid at specific locations to generate localized vortices that collectively accelerate the decoating process across the entire workpiece surface.
Solution Approach 2:
The system employs periodic dosing of fluid through the dosing tubes to create oscillating turbulence patterns. This periodic action prevents stagnant zones and continuously renews the mechanical detachment effect on the coating surface, significantly reducing the overall decoating time compared to continuous or static fluid introduction.
2Productivity
If dosing tubes are arranged near the bottom of the tank, then workpieces can be flushed by rising air bubbles, but the arrangement must be compact and space-saving
Solution Approach 1:
The dosing tubes are designed with meandering or curved paths instead of straight configurations. This curvature allows the tubes to fit compactly within the tank volume while still extending fluid introduction throughout the workspace, achieving both space efficiency and effective turbulence generation for high decoating productivity.
Solution Approach 2:
Multiple dosing tubes are nested or arranged in hierarchical configurations where smaller tubes are positioned within or alongside larger tube structures. This nesting approach maximizes the number of active dosing points within limited tank space, enabling comprehensive workpiece flushing without increasing overall device complexity.
3Loss of time
If multiple dosing tubes are used to create turbulence, then decoating time is reduced, but the structure becomes more complex
Solution Approach 1:
Each dosing tube is designed to perform multiple functions: introducing fluid for turbulence generation, providing structural support for workpiece positioning, and serving as a flow distribution element. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity despite using multiple dosing tubes to achieve rapid decoating.
Solution Approach 2:
Adjacent dosing tubes are merged into integrated manifolds or common distribution headers that serve multiple tubes simultaneously. This merging approach reduces the total number of independent connections and control elements required, maintaining simpler overall structure while still utilizing multiple dosing points to minimize decoating time.
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
The system significantly reduces decoating time by combining chemical and mechanical processes, allowing for precise fluid management and optimal turbulence, thereby accelerating the removal of surface layers.
Implementation Method 1
The supply of a fluid into the solution of a decoating tank can lead to turbulence, particularly on the workpieces to be decoated. The decoating of entire layer pieces can be facilitated by mechanically moving or swirling them by means of an ascending fluid flow.
Implementation Method 2
arranging the dosing pipes near the floor ensures that the workpieces arranged above them are flushed by the rising air bubbles, which promotes the decoating process
