Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial parts washers are inflexible, occupy significant space, and are inefficient in terms of energy consumption, making it costly to adjust conveyor speeds, add stages, or change chemical processes, and they lack easy access for maintenance and filtration systems.
Innovation Solution
A modular, in-line pretreatment system with concatenated wash stages and drip modules that allow for adjustable exposure time and chemical changes, featuring a compact design with easy access to interior components and integrated filtration, reducing energy consumption and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional washer booth is built with fixed length stages, then the structure is simple and stable, but the exposure time cannot be adjusted without adding length or sacrificing soak time
Solution Approach 1:
The washer is divided into multiple independent modular stages that can be configured in series. Each module contains complete washing functionality (spray nozzles, heating, pumping), allowing the system to be assembled in different lengths to achieve desired exposure times without redesigning the entire system.
Solution Approach 2:
The system allows dynamic adjustment of the number of stages engaged in the washing process. Modules can be added or removed from the conveyor path to change total exposure time, and conveyor speed can be varied to adjust throughput while maintaining optimal soak time in each stage.
2Productivity
If the washer length is increased to add more stages or increase throughput, then the cleaning capacity improves, but the factory floor space occupied increases significantly
Solution Approach 1:
The washing system transitions from a horizontal floor-space-intensive layout to a vertical arrangement where multiple modular stages are stacked or arranged in a compact configuration along the conveyor path. This allows increased cleaning capacity without proportional increase in floor space occupation.
3Adaptability or versatility
If the washer is built as a fixed structure, then the initial construction is straightforward, but future modifications to add stages or change processes require major projects at considerable expense
Solution Approach 1:
The washer is divided into multiple independent modular stages that can be configured in series. Each module contains complete washing functionality (spray nozzles, heating, pumping), allowing the system to be assembled in different lengths to achieve desired exposure times without redesigning the entire system.
Solution Approach 2:
Each modular stage is designed with universal interfaces and standardized components that allow them to function independently or in combination with other stages. This universality enables easy reconfiguration, addition, or removal of stages without custom engineering, reducing both initial construction complexity and future modification costs.
4Reliability
If traditional filtration systems are added to keep the bath clean, then the bath life extends, but additional pumps and floor space are required
Solution Approach 1:
The filtration system is integrated within the modular stage structure itself rather than being a separate external system. The filter is positioned to receive waste directly from the spray process, eliminating the need for additional pumps and separate filtration equipment while extending bath life through continuous filtering.
5Ease of operation
If the washer booth is constructed as a enclosed structure, then the cleaning process is contained and effective, but access to interior piping and nozzles for maintenance is difficult
Solution Approach 1:
The enclosed washer structure is segmented into multiple accessible modular stages. Each module can be independently opened or removed to provide direct access to interior piping, nozzles, and other components requiring maintenance, eliminating the need to open or dismantle a large enclosed structure.
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 provides flexibility in adjusting exposure time and chemical processes, reduces energy and space needs, and allows for easy maintenance, enabling high-volume throughput with low capital and operating costs, while adapting to changing production demands.
Implementation Method 1
A motor-driven pump, preferably a centrifugal pump, is arranged to draw the cleaning liquid from the tank and supply it via the headers to the risers and nozzles
Implementation Method 2
machined parts must be chemically cleaned to remove oils and other residues therefrom before painting or powder coating operations can be performed on these parts
Implementation Method 3
Pressure of the liquid spray on the part (impingement)

AI summary
An in-line parts washing system comprising concatenated modules of two discrete lengths where certain of the modules have a self-contained tank of parts cleaning chemical along with a motor-driven pump for forcing the cleaning chemical through spray heads enclosed in a shroud through which the parts to be cleaned are transported via a conveyor. Other modules disposed in-line with the wash modules provide zones where the cleaning chemical dripping from the parts is collected and redirected back into the tanks from which it originated. The ability to swap modules of differing length allows a user to easily alter the cleaning process.
