Solution Overview

Problem

Pet hair often becomes embedded in carpets and upholstery, making it difficult for traditional vacuum cleaners to remove completely, as much of the hair gets trapped within the fabric fibers.

Innovation Solution

An accessory tool with a main housing assembly, suction nozzle, and hair collecting elements that create a balling effect to aggregate pet hair, allowing it to be easily ingested by the vacuum cleaner, featuring directional fabric and channels to guide hair towards the suction nozzle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a traditional vacuum cleaner is used to remove pet hair from fabric surfaces, then some hair can be suctioned up, but a good portion of the hair becomes trapped within the fabric fibers and cannot be removed

Engineering Contradiction:
Improvehair removal effectivenessVSAvoidcomplete hair removal
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The hair removal system is segmented into two distinct functional components: (1) hair collecting elements that mechanically agitate and lift hair from fabric surfaces, and (2) a suction nozzle that captures and removes the liberated hair through airflow. This segmentation allows each component to specialize in its function, with the collecting elements focusing on hair liberation and the suction nozzle focusing on hair removal, thereby resolving the contradiction between initial hair pickup and complete hair removal.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hair collecting elements perform a preliminary action by mechanically agitating the fabric surface and lifting embedded hair before the suction process occurs. This preliminary agitation prepares the hair for effective suction by positioning it above the fabric surface, ensuring that the subsequent suction action can completely remove the hair rather than just picking up loose particles.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If hair collecting elements are added to create a balling effect, then hair removal effectiveness improves, but the device complexity increases

Engineering Contradiction:
Improvehair aggregation capabilityVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The hair collecting elements are integrated directly into the housing structure of the vacuum accessory tool, merging the agitation function with the existing device body rather than adding a separate mechanical agitation device. The collecting elements are positioned to work in conjunction with the suction nozzle, combining hair agitation and hair capture functions into a unified system that achieves effective hair removal without proportionally increasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hair collecting elements are designed to automatically ball up and aggregate hair as it is liberated from the fabric surface, creating a self-organizing effect where the airflow and element geometry work together to concentrate hair into removable clumps without requiring additional mechanical components or user intervention.

Inventive Principle:
Principle #25Self-service

3Productivity

If the suction nozzle is positioned centrally on the underside, then hair can be effectively channeled towards it, but the area for hair collecting elements is reduced

Engineering Contradiction:
Improvehair channeling efficiencyVSAvoidcollecting element surface area
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The underside of the accessory tool features localized variations in structure: the central region contains the suction nozzle optimized for capturing and removing hair, while the peripheral regions contain hair collecting elements optimized for liberating and aggregating hair. This local differentiation allows each zone to perform its specialized function effectively, with the peripheral collecting elements compensating for their smaller individual area by working in concert with the central suction nozzle.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The hair collecting elements extend vertically from the underside surface, utilizing the vertical dimension to increase their effective surface area for hair contact without increasing the horizontal footprint. This vertical extension allows the collecting elements to engage with fabric surfaces more effectively while maintaining a compact overall device size and preserving central suction nozzle functionality.

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