Solution Overview
Problem
Existing air stream cleaning systems face challenges in effectively separating a wide variety of paint particles and mist due to differences in particle size and moisture content, leading to structural collapse under load and reduced functionality.
Innovation Solution
A modular system with a hollow body and interchangeable cleaning sub-structures, including filter and separation structures, designed to accommodate different particle sizes and moisture levels, featuring stabilization walls and foldable deposition structures for enhanced stability and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cleaning modules are located in the floor of the spray booth to handle large particle sizes and high moisture content, then separation capacity is improved, but the internal separation structures collapse under their own weight laden with paint
Solution Approach 1:
The cleaning module is divided into multiple independent separation structures (labyrinths) that are arranged in series. Each labyrinth is a self-supported unit with its own inlet and outlet, allowing the load to be distributed across multiple segments rather than concentrated on a single structure. This segmentation prevents collapse while maintaining high separation capacity.
Solution Approach 2:
The separation structures are arranged in a multi-dimensional configuration within the hollow body, with labyrinths positioned at different heights and orientations. This spatial distribution reduces the concentration of paint load on any single structure and provides multiple load-bearing paths, enhancing overall structural stability under heavy contamination conditions.
2Device complexity
If a single cleaning module design is used for all paint types, then device complexity is reduced, but adaptability to different particle sizes and moisture contents is limited
Solution Approach 1:
The cleaning module is designed as a universal system where the same hollow body and module framework can accommodate different types of separation structures (labyrinths, filters, cyclones) depending on the paint characteristics. The standardized interface and interchangeable internal components allow one module design to handle various particle sizes and moisture contents effectively.
Solution Approach 2:
The module configuration is made dynamic and adjustable, allowing the internal separation structures to be repositioned, removed, or replaced based on the specific paint type being processed. This adaptability enables the same physical module to optimize its performance for different contamination conditions without requiring multiple fixed designs.
3Productivity
If multiple cleaning modules are arranged in series to handle varying contamination, then separation efficiency is improved, but storage space requirements increase
Solution Approach 1:
Multiple separation structures (labyrinths, filters, cyclones) are nested within a single hollow body module, with each structure positioned inside or adjacent to the others. This nested arrangement allows several cleaning functions to be performed in one compact module, reducing the number of separate modules needed and minimizing storage space requirements while maintaining high separation efficiency.
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 modular system allows for broader applicability and improved separation efficiency across varying contamination types, reducing storage needs and ensuring complete air flow cleaning while maintaining structural integrity under load.
Implementation Method 1
For relatively small, dry particles, labyrinths with small openings and sharp bends must be provided for separation, so that the particles are stopped by their inertia (or by centrifugal force) against the impact walls of the labyrinth or separator
Implementation Method 2
For relatively small, dry particles, labyrinths with small openings and sharp bends must be provided for separation, so that the particles are stopped by their inertia (or by centrifugal force) against the impact walls of the labyrinth or separator
Implementation Method 3
To remove even very fine paint mist from the airflow, the at least two cleaning component structures can be designed to include a filter structure
