Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a spacious box-like nozzle design is used to cover large floor area, then the coverage area is improved, but the suction efficiency deteriorates and energy consumption increases

Engineering Contradiction:

Improvecoverage areaVSAvoidenergy consumption

Core Design Contradiction:

Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

The patent employs a flexible membrane structure that forms a thin, flat nozzle body instead of a rigid box-like design. This flexible construction allows the nozzle to conform to narrow spaces while maintaining structural integrity, reducing the overall volume and material usage while preserving coverage capability

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The invention transitions from a three-dimensional box-like structure to a two-dimensional thin flat design. By flattening the nozzle profile and optimizing the planar arrangement of suction openings, the patent achieves large coverage area without increasing vertical dimension, thereby reducing air volume capacity and energy requirements

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If a spacious box-like nozzle design is used to cover large floor area, then the coverage area is improved, but the suction efficiency deteriorates

Engineering Contradiction:

Improvecoverage areaVSAvoidsuction efficiency

Core Design Contradiction:

Area of stationary objectVSProductivity

Solution Approach 1:

The patent implements non-uniform distribution of suction openings with varying diameters across the nozzle surface. openings closer to the suction source have different characteristics than those farther away, optimizing local suction efficiency while maintaining overall coverage. This localized optimization ensures that each region contributes maximally to dust capture

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The flexible membrane construction enables the nozzle to adapt its shape to narrow spaces and tight corners, maintaining effective suction contact with the surface being cleaned. This flexibility ensures consistent suction efficiency across varied geometries without requiring a bulky rigid structure

Inventive Principle:

Principle #30Flexible shells and thin films

3Area of stationary object

If a spacious box-like nozzle design is used, then the coverage area is improved, but air leakage increases

Engineering Contradiction:

Improvecoverage areaVSAvoidair leakage

Core Design Contradiction:

Area of stationary objectVSLoss of energy

Solution Approach 1:

The flexible membrane acts as a sealing element that conforms to the surface geometry, creating an airtight interface between the nozzle and the floor. This flexible seal prevents air leakage from occurring at the contact interface, ensuring that all suction air is directed through the controlled openings rather than escaping around the edges

Inventive Principle:

Principle #30Flexible shells and thin films

4Area of stationary object

If a spacious box-like nozzle design is used, then the coverage area is improved, but dust capture efficiency deteriorates

Engineering Contradiction:

Improvecoverage areaVSAvoiddust capture efficiency

Core Design Contradiction:

Area of stationary objectVSProductivity

Solution Approach 1:

The patent employs differentiated suction openings with varying diameters and distributions across the nozzle surface. This local variation optimizes dust capture in different regions, ensuring that openings closer to the suction source handle larger particles while finer openings capture smaller dust particles, thereby improving overall dust capture efficiency across the entire coverage area

Inventive Principle:

Principle #3Local quality

AI summary

A nozzle with a knee and housing unit for attachment to hose of a vacuum cleaner with an elongated unit for contact with suction area, as a floor. Housing and elongated unit are flexible joined so for easy maneuverability of nozzle. The elongated unit forms a thin and flat narrow shape which is partially enclosed and has a certain air volume capacity. The elongated unit is made narrower towards the end from knee and housing unit and has a flat floor surface and panel with suction openings facing suction area. The air suction openings have different diameters and size based on distance from source of air suction which optimize the effect of suction and allows suction from all directions.
