Solution Overview
Problem
Efficient and reliable cleaning of internal combustion engine components, such as injectors, is hindered by contamination, which affects engine performance and safety, particularly in applications like helicopters.
Innovation Solution
A cleaning device with an adapter, cleaning medium reception chamber, and drive unit for flowing and collecting cleaning medium, allowing visual inspection and analysis of cleaning success, and a system for simultaneous cleaning of multiple components with heated medium and precise flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cleaning medium is driven through the device to be cleaned without collection, then the cleaning process is simple, but cleaning success cannot be verified
Solution Approach 1:
The patent introduces a cleaning medium reception chamber as an intermediary component between the device to be cleaned and the cleaning medium reservoir. This chamber collects the cleaning medium after it passes through the device, enabling verification of cleaning success by examining the collected medium for contaminants, while maintaining a relatively simple overall device structure.
2Productivity
If multiple devices are cleaned simultaneously, then productivity increases, but device complexity and flow control difficulty increase
Solution Approach 1:
The patent designs the cleaning device with a universal adapter system that can accommodate multiple different devices to be cleaned. The cleaning medium reception chamber and drive unit serve multiple functions: they work with any device mounted on the adapter, collect cleaning medium for verification, and enable simultaneous or sequential cleaning of multiple devices, thereby increasing productivity without proportionally increasing complexity.
3Measurement precision
If cleaning medium is not collected, then loss of substance is minimized, but measurement and analysis of cleaning effectiveness is impossible
Solution Approach 1:
The cleaning medium reception chamber provides a feedback mechanism by collecting and storing the cleaning medium after it passes through the device to be cleaned. This allows for measurement and analysis of cleaning effectiveness by examining the collected medium for presence of contaminants, while the chamber's design enables the cleaning medium to be retained and potentially reused, minimizing substance loss.

Function Achieved in This Case
Ensures thorough cleaning with immediate verification of success, enhances safety, and increases efficiency by allowing multiple devices to be cleaned simultaneously with precise control and reuse of cleaning medium.
Implementation Method 1
a drive unit for driving cleaning medium from a cleaning medium reservoir through the device to be cleaned, when mounted on the adapter, and into the cleaning medium reception chamber
Implementation Method 2
a thermal block which is thermally coupled to the drive unit, in particular a motor unit of the drive unit, and thermally coupled to the cleaning medium flowing to the adapter or the cleaning medium reservoir for providing a thermal bridge between the cleaning medium and the drive unit
