Solution Overview
Problem
Existing container cleaning machines are inefficient in removing aggressive dirt and labels with high energy and construction effort.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If greater energy and material consumption is used to remove heavy soiling or labels, then cleaning effectiveness is improved, but energy consumption and material consumption increase
Solution Approach 1:
The patent employs hydraulic principles through the injector nozzle to generate high-velocity cleaning fluid flow. The nozzle converts pressure energy into kinetic energy, creating a focused jet that impacts contaminants with sufficient force to remove heavy soiling and labels without requiring excessive overall system energy consumption.
Solution Approach 2:
The invention changes the flow parameters of the cleaning medium by using an injector nozzle to transform the cleaning fluid into a high-velocity jet. This parameter change (from low-velocity bulk flow to high-velocity directed jet) increases the cleaning effectiveness on stubborn contaminants while maintaining reasonable energy input levels.
2Reliability
If more aggressive cleaning methods are used to remove stubborn dirt and labels, then cleaning results are improved, but device complexity and construction effort increase
Solution Approach 1:
The patent extracts the cleaning function from complex mechanical systems and concentrates it into a simple hydraulic jet generated by the injector nozzle. This extraction of the core cleaning mechanism into a single focused flow source simplifies the overall device structure while maintaining effective cleaning capability.
Solution Approach 2:
By relying on hydraulic flow dynamics rather than mechanical contact (such as brushes or impactors), the invention achieves aggressive cleaning action with minimal mechanical complexity. The injector nozzle and fluid dynamics system replace what would otherwise require complex mechanical cleaning mechanisms.
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
This configuration improves the cleaning result by increasing the impact of cleaning fluid on stubborn dirt and labels while minimizing energy expenditure and construction effort, with the ability to recycle cleaning fluid for reuse.
Implementation Method 1
The injector nozzle can preferably operate according to the Venturi principle, thus delivering more cleaning fluid from an outlet opening of the injector nozzle in the outflow direction than was supplied to the injector nozzle via a pump
