Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional snow plows are used, then snow can be removed from the surface, but the removal efficiency is low and costs are high

Engineering Contradiction:
Improvesnow removal efficiencyVSAvoidtime for snow clearance
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The invention combines multiple functions into a single integrated device: the conveyor screw serves both as a snow collection mechanism and a compaction device, while the pump system handles both snow transport and water injection for surface cleaning. This merging of functions increases productivity by eliminating the need for separate plowing and cleaning operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device changes the physical state and properties of snow through controlled compaction. By adjusting the conveyor screw rotation speed, water injection rate, and compaction pressure, the system transforms loose snow into compacted snow that can be efficiently loaded onto vehicles, significantly improving removal efficiency.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If snow is removed using traditional methods, then snow clearance is achieved, but surface integrity and cleanliness are compromised

Engineering Contradiction:
Improvesurface integrityVSAvoidresidual snow and debris
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention replaces traditional mechanical plowing with a pump-based system that uses water injection and controlled compaction. This substitution allows for more precise control over the snow removal process, maintaining surface integrity while achieving thorough clearance without the harsh mechanical forces of conventional plows.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs self-cleaning through the pump mechanism that injects water to flush the surface during operation. This self-service cleaning function ensures that residual snow and debris are removed while maintaining surface integrity, eliminating the need for separate cleaning passes.

Inventive Principle:
Principle #25Self-service

3Productivity

If snow is compacted and transported, then removal efficiency increases, but device complexity increases

Engineering Contradiction:
Improvesnow compaction and transport efficiencyVSAvoiddevice structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The conveyor screw performs multiple functions: it collects snow from the surface, compacts the snow through rotational pressure, and transports the compacted snow to loading positions. This multi-functionality reduces the need for separate components, thereby managing device complexity while maintaining high productivity.

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

Solution Approach 2:

The horizontal auger is nested within the concave snow plow structure, and the conveyor screw operates within the pump housing. This nested arrangement optimizes space utilization and reduces the overall footprint of the device, managing structural complexity while enabling efficient snow compaction and transport.

Inventive Principle:
Principle #7Nested doll (Nesting)
