Solution Overview

Problem

Existing vacuum cleaners face difficulties in ergonomically replacing the vacuum bag without soiling the user or their environment due to the vacuum bag rubbing against internal walls during removal, and the access mechanism being cumbersome.

Innovation Solution

A vacuum cleaner design with a waste separation and collection device featuring a receiving compartment open upwards, a movably mounted closing hood accessible from above, and a gripping handle positioned to facilitate easy bag insertion and removal, reducing contact with internal walls and minimizing dust dispersion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the access opening is located at the front end of the main body and the closing hood is pivotally mounted on the front end, then the structure is simple, but removing the vacuum bag requires moving it away from the grip handle which is difficult for users

Engineering Contradiction:
Improvestructural simplicityVSAvoidbag removal ease
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent relocates the access opening from the front end to the upper part of the main body, changing the spatial dimension of access. This allows users to reach the closing hood and remove bags from above while holding the handle, transforming a horizontally constrained operation into a vertically accessible one that does not require moving the bag away from the handle

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

2Ease of operation

If the vacuum bag is removed from the receiving compartment in the prior art configuration, then bag removal is possible, but the bag rubs against internal walls causing waste to be evacuated and soiling the user's hands or environment

Engineering Contradiction:
Improvebag removal capabilityVSAvoidwaste dispersion and soiling
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

By positioning the access opening in the upper part of the main body and allowing bag removal from above, the patent creates a removal path that is vertically oriented rather than horizontally constrained. This dimensional change enables users to extract bags straight upward without the bag contacting the lateral internal walls of the receiving compartment, thereby preventing waste evacuation and environmental soiling

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