Solution Overview

Problem

Existing small vacuum cleaners lack a simplified mechanism for transitioning between handheld and stick vacuum operations, requiring separate fans and additional components for different modes of use.

Innovation Solution

A compact small vacuum cleaner design with a dust separation device, a fan, and an electric motor that can be connected to a suction stick frame, allowing the small vacuum cleaner to operate as both a handheld unit and a stick vacuum using an enveloping body for secure insertion and easy handling, with a handle for ergonomic use and efficient dust separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a small vacuum cleaner is designed to operate both as a handheld unit and as a stick vacuum, then versatility is improved, but device complexity increases due to requiring multiple fans and additional components for different operating modes

Engineering Contradiction:
Improveoperating modesVSAvoidcomponents
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The small vacuum cleaner is designed with a universal fan and dust collection chamber that can operate in both handheld and stick vacuum modes. The same fan generates suction air flow for both operating modes, and the dust collection chamber serves dual purposes without requiring separate components for each mode.

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

Solution Approach 2:

The invention merges the handheld vacuum cleaner and stick vacuum frame into a unified system where the small vacuum cleaner can be connected to the vacuum cleaner frame to form an integrated unit. This combination allows a single device to function as both handheld and stick vacuum, eliminating the need for separate devices.

Inventive Principle:
Principle #5Merging (Combining)

2Power

If a small vacuum cleaner is connected to a vacuum cleaner frame to form a stick vacuum unit, then suction power is improved, but ease of operation deteriorates due to complicated connection and disconnection procedures

Engineering Contradiction:
Improvesuction powerVSAvoidconnection procedure
Core Design Contradiction:
PowerVSEase of operation

Solution Approach 1:

The small vacuum cleaner is designed to be inserted into and nested within the vacuum cleaner frame in a radial direction. This nesting arrangement allows the small vacuum cleaner to be securely held by the frame while maintaining easy connection and disconnection capabilities.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The connection mechanism is segmented into separate components including a holding body with opening and a dust collection chamber with corresponding opening, allowing independent movement and connection of parts. This segmentation enables simple connection and disconnection operations while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the small vacuum cleaner is firmly connected to the vacuum cleaner frame via joints and notches, then reliability is improved, but ease of manufacture deteriorates due to complex assembly requirements

Engineering Contradiction:
Improveconnection stabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The connection system incorporates a movable locking element that can shift between locked and unlocked positions. This dynamic element allows the connection to be firmly secured during operation while enabling simple assembly and disassembly during manufacturing and maintenance.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A locking element acts as an intermediary between the holding body and the dust collection chamber, providing reliable connection through engagement with locking surfaces while simplifying the overall assembly process. The locking element mediates the connection, ensuring stability without requiring complex joint structures.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A combination made up of a small vacuum cleaner (1), which comprises a dust collector (10), a fan for generating a suction?air stream through the dust collector (10), and an electric motor (25) for driving the fan, and of an upright?vacuum?cleaner frame (40), wherein the small vacuum cleaner (1) can be connected to the upright?vacuum?cleaner frame (40) to form a unit which can be operated as an upright vacuum cleaner, and wherein the upright?vacuum?cleaner frame (40) comprises a casing body (41), into which the small vacuum cleaner (1) can be inserted. The invention also relates to such a small vacuum cleaner and to a correspondingly designed upright?vacuum?cleaner frame. This makes it possible to improve the handling as a small vacuum cleaner and/or as an upright vacuum cleaner and/or to simplify the measures necessary for connecting the small vacuum cleaner to the upright?vacuum?cleaner frame for operation as an upright vacuum cleaner.
