Solution Overview

Problem

Existing hand vacuum cleaners require disconnecting cleaning tools or accessories when emptying the cyclone bin, which is inconvenient and may lead to spillage during emptying.

Innovation Solution

A portable surface cleaning apparatus with a removably mounted cyclone bin assembly that nests within the body, allowing for easy removal and emptying without disconnecting tools or accessories, and maintaining a sealed unit to prevent spillage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cyclone bin assembly is removed for emptying, then the cyclone bin can be emptied, but any cleaning tool or accessory connected to the inlet must be disconnected first

Engineering Contradiction:

Improveease of emptying cyclone binVSAvoidcomplexity of disconnection procedure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The cyclone bin assembly is segmented as a separate removable component from the main body, allowing it to be detached independently. The mounting structure includes a mounting surface on the body and a corresponding removable mounting structure on the cyclone bin assembly with engagement features that allow easy attachment and detachment without requiring disconnection of cleaning tools or accessories.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cyclone bin assembly is extracted as a standalone removable unit from the integrated structure. This extraction allows the cyclone bin to be removed and emptied independently while the cleaning tools remain attached to the inlet on the main body, eliminating the need to disconnect accessories for emptying.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If the cyclone bin assembly is made removable, then it can be easily emptied, but the overall volume of the cleaning apparatus increases

Engineering Contradiction:

Improveease of emptying cyclone binVSAvoidvolume of cleaning apparatus

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The cyclone bin assembly is designed to nest within the body when mounted. The cyclone bin assembly includes a cyclone chamber and a dirt collection chamber that can be received within the body housing, creating a compact nested configuration that reduces the overall volume of the cleaning apparatus while maintaining full functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A hand carryable surface cleaning apparatus comprises a body housing a suction motor and comprising a handle. The handle has a handgrip portion that extends upwardly in an upward direction when the surface cleaning apparatus is disposed on a horizontal surface, wherein the handle and a rear surface of the body define a finger gap in which a user may place the user's fingers while gripping the handle. The suction motor is positioned adjacent the rear surface of the body.
