Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning methods for fluid delivery systems, such as those used in the automotive industry, often fail to completely remove abrasive media and deposits from interior surfaces, necessitating a more effective method for cleaning and residue removal.
Innovation Solution
A method involving a series of liquids and particulates is introduced into the fluid delivery system, where a first liquid contacts the surface, followed by a slurry formed with abrasive particulates, and then a second and third liquid are used to displace and dissolve the particulates and residual liquids, ensuring thorough cleaning and removal of deposits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If abrasive media particulate is incorporated into the cleaning solution to thoroughly clean the piping and related equipment, then the cleaning effectiveness is improved, but the difficulty of completely removing the abrasive media material after cleaning increases
Solution Approach 1:
The invention changes the chemical parameters of the cleaning solution by incorporating specific solvents and chemicals that alter the properties of the abrasive media, enabling it to be thoroughly removed after cleaning. The solution includes materials like water, organic solvents, and surfactants that modify the abrasive media's solubility and removability while maintaining cleaning effectiveness.
Solution Approach 2:
The invention uses a specially formulated liquid cleaning solution as an intermediary substance that facilitates both the cleaning action and the subsequent removal of abrasive media. The solution acts as a mediator between the abrasive particles and the system surfaces, enabling effective cleaning while ensuring the abrasive materials can be completely flushed away with water or other solvents.
2Ease of operation
If conventional liquid blends are used to solubilize and remove deposits, then the process is simple to operate, but the cleaning effectiveness is insufficient to return piping to original build condition
Solution Approach 1:
The invention uses composite cleaning solutions that combine multiple materials including water, organic solvents, surfactants, and abrasive particulates. This composite formulation provides both the simplicity of a liquid-based system and the enhanced cleaning effectiveness of abrasive action, achieving original build condition cleanliness while remaining easy to operate.
Solution Approach 2:
The invention merges the advantages of conventional liquid blends with abrasive cleaning by combining solubilizing agents and abrasive particulates in a single cleaning solution. This unified approach maintains the ease of liquid application while adding the mechanical cleaning power of abrasives to achieve thorough removal of deposits.

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 method effectively removes deposits from fluid delivery system surfaces by a combination of dissolution, abrasion, and adhesion loss, ensuring the system is thoroughly cleaned and the cleaning materials are completely removed, maintaining the original cleanliness of the components.
Implementation Method 1
conventional cleaning methods for fluid delivery systems, such as those used in the automotive industry, often fail to completely remove abrasive media and deposits from interior surfaces
Implementation Method 2
this shortcoming was addressed by incorporating an abrasive media particulate into the cleaning solution which, when compared to the various liquid blends discussed above, cleaned the piping and related equipment of a fluid delivery system more thoroughly
Implementation Method 3
introducing a second liquid into the fluid delivery system and contacting the interior surface with the second liquid; and introducing a third liquid into the fluid delivery system and contacting the interior surface with the third liquid
