Solution Overview

Problem

Vacuum cleaners with horizontally arranged electric motors occupy excessive space, limiting the arrangement of other components and increasing the motor housing volume, leading to inefficiencies and operational limitations.

Innovation Solution

A clutch device is introduced between the electric motor assembly and the machine body assembly in an upright vacuum cleaner, featuring a sliding track, toggling tongue, and lever member to rotate the electric motor, allowing for adjustment of the drive belt tension and ensuring steady operation with a compact structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the dust container is disposed of after filling, then the structure is simple, but it causes environmental pollution and resource waste

Engineering Contradiction:
Improvestructural simplicityVSAvoidenvironmental pollution
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The dust container is designed to be separable into multiple components (container body, lid, filter assembly) that can be selectively reused. The container body and lid can be retained and refilled, while only the filter assembly requires replacement after a certain usage period, thereby reducing waste and environmental pollution while maintaining manufacturing simplicity

Inventive Principle:
Principle #34Discarding and recovering

2Ease of operation

If the dust container is made separable, then it is easy to clean and maintain, but the structure becomes complex

Engineering Contradiction:
Improvecleaning convenienceVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The dust container is divided into distinct modular components: the container body, the lid with sealing mechanism, and the filter assembly. These segments can be easily separated from each other through simple disconnection interfaces, allowing users to remove and clean each component independently without requiring complex disassembly procedures

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the separator is positioned far from the dust container, then it is easy to dispose of dust, but dust may be scattered during transport

Engineering Contradiction:
Improvedust disposal convenienceVSAvoiddust scattering
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

A dedicated dust discharge path is provided that serves as an intermediary channel between the dust container and the separator. This enclosed path allows dust to be transported from the container to the separator without being exposed to the external environment, preventing dust scattering while maintaining easy disposal operation

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A clutch device (400) for an upright vacuum cleaner and an upright vacuum cleaner (1) having the same are provided, in which the clutch device (400) is disposed between an electric motor assembly (200) and a machine body assembly (300) of the upright vacuum cleaner (1), and the electric motor assembly (200) includes an electric motor housing (21) and an electric motor (22). The clutch device (400) includes: a sliding track (41d) driven (300) to move by the machine body assembly; a toggling tongue (42d) fixed to the electric motor (22) and rotatable with respect to the electric motor housing (21); and a lever member (43d) having a second end of the lever member (43d) slidably fitted to the sliding track (41d) and a first end fitted with an end of the toggling tongue (42d). When the machine body assembly (300) drives the sliding track (41d) to move, the sliding track (41d) drives the lever member (43d) to rotate, and when the lever member (43d) rotates, the toggling tongue (42d) is stirred to make the electric motor (22) rotate with respect to the electric motor housing (21).
