Solution Overview

Problem

Existing dirt vacuum cleaners with obliquely inclined filters are difficult to maintain, as accessing and replacing the filters requires kneeling and disassembling the device, making it labor-intensive.

Innovation Solution

The filter is housed in a pivoting housing that can be swiveled on a horizontal axis, allowing easy access and replacement without disassembling the vacuum cleaner, and enabling the integration of additional cleaning devices within the pivoting flap.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If the filter is arranged obliquely inclined in the housing to improve service life, then the filter service life is improved, but the filter becomes difficult to access and replace requiring kneeling and disassembly

Engineering Contradiction:
Improvefilter service lifeVSAvoidfilter accessibility
Core Design Contradiction:
Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The housing is designed with a pivoting section that can rotate between a closed position (during operation) and an open position (during maintenance). This dynamic structure allows the filter to remain obliquely inclined for optimal service life while enabling easy access by simply pivoting the housing section, eliminating the need for kneeling or disassembly.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The housing is divided into separate sections with at least one section designed to pivot open. This segmentation allows the filter to maintain its oblique arrangement for improved service life while the pivoting section provides independent access to the filter without requiring disassembly of the entire housing.

Inventive Principle:
Principle #1Segmentation

2Duration of action of stationary object

If the filter is arranged obliquely inclined to improve service life, then the filter service life is improved, but the device complexity increases due to additional housing structure

Engineering Contradiction:
Improvefilter service lifeVSAvoidhousing structure
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

Instead of creating a completely new complex structure, the invention uses a simple pivoting mechanism integrated into the existing housing. This dynamic element allows the filter to be obliquely arranged for improved service life while adding minimal structural complexity through the pivoting section that can rotate between closed and open positions.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the housing is made swivelable to improve filter accessibility, then the filter becomes easily accessible, but the device complexity increases

Engineering Contradiction:
Improvefilter accessibilityVSAvoidhousing structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The housing is segmented into a fixed portion and a pivoting portion connected by hinges. This segmentation allows the pivoting section to be opened independently for filter access without affecting the overall structural integrity of the housing, thereby improving accessibility while limiting the increase in device complexity to only the necessary pivoting mechanism.

Inventive Principle:
Principle #1Segmentation
