Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional container cleaning machines use long exposure times in caustic baths, then cleaning effectiveness is improved, but the machine size and processing time increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent employs hydraulic jet systems with high-pressure liquid streams to clean container surfaces. The jet cleaning mechanism uses focused fluid dynamics to remove contaminants rapidly, replacing the need for prolonged chemical exposure while maintaining cleaning effectiveness and reducing processing time

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The invention changes the physical parameters of the cleaning process by using high-pressure liquid jets instead of prolonged chemical immersion. The jet system delivers concentrated cleaning force through increased pressure and velocity parameters, achieving the same cleaning effect in shorter time periods

Inventive Principle:
Principle #35Parameter changes

2Productivity

If conventional container cleaning machines use large quantities of containers in container baskets, then cleaning capacity is improved, but the machine dimensions increase

Engineering Contradiction:
Improvecleaning capacityVSAvoidmachine length
Core Design Contradiction:
ProductivityVSLength of stationary object

Solution Approach 1:

The cleaning system is divided into modular segments with multiple jet cleaning stations arranged in series. Each station handles a portion of the container flow, allowing high-volume processing within a compact footprint by distributing the cleaning capacity across several focused modules rather than requiring a single large chamber

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes vertical stacking and three-dimensional arrangement of jet cleaning stations to increase processing capacity without proportionally increasing machine length. Containers move through a compact path with cleaning applied from multiple angles and levels, maximizing space utilization

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If container baskets are designed as compromise solutions for different container sizes, then versatility is improved, but cleaning precision decreases

Engineering Contradiction:
Improvecontainer size accommodationVSAvoidcleaning precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The jet cleaning system is designed with universal applicability to handle various container types and sizes. The high-pressure liquid jets can be directed at different angles and positions to effectively clean diverse container geometries, replacing the need for size-specific basket designs while maintaining cleaning precision through adjustable jet targeting

Inventive Principle:
Principle #6Universality (Multi-functionality)
