Solution Overview

Problem

Existing handheld vacuum cleaners are contaminated by pet feces and lack a simple mechanism for easily ejecting or discarding disposable waste bags, making the process frustrating and unsanitary.

Innovation Solution

A portable handheld vacuum device with a disposable bag that can be easily ejected and replaced, eliminating direct contact with pet waste through a mechanism that allows for contactless disposal into a trash receptacle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If a re-usable waste collection bag is used in handheld vacuum cleaners, then the device can be used multiple times, but the bag needs to be washed after picking up pet waste which is frustrating and unsanitary

Engineering Contradiction:
Improvere-usable waste collection bagVSAvoidwashing the waste collection bag
Core Design Contradiction:
Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The patent applies the disposable bag principle by replacing the re-usable washable bag with a disposable bag that is discarded after a single use. This eliminates the need to wash the bag after picking up pet waste, directly resolving the contradiction between re-usability and ease of operation. The disposable bag is inserted into the vacuum device, used once, then removed and thrown away, making the process sanitary and frustration-free.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Ease of operation

If handheld vacuum cleaners are equipped with a disposable waste collection bag, then the bag can be discarded after use, but there is lack of a simple mechanism to easily eject or discard the collection bag containing pet waste

Engineering Contradiction:
Improvediscarding the collection bagVSAvoidejection mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies the extraction principle by providing a dedicated bag ejection mechanism that extracts the disposable bag from the vacuum device. The mechanism includes a bag ejection button that, when pressed, releases the bag from its retained position, allowing easy removal and disposal. This resolves the contradiction by providing a simple one-button operation for bag ejection without adding complex mechanical systems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies the self-service principle through the automatic bag ejection mechanism that uses spring-loaded or elastic forces to automatically expel the bag when the ejection button is pressed. The system serves itself by using stored mechanical energy to perform the ejection action, requiring minimal user input (just pressing the button) and eliminating the need for manual manipulation of the bag.

Inventive Principle:
Principle #25Self-service

3Productivity

If the vacuum cleaner picks up pet waste, then the waste is collected, but the vacuum cleaner becomes contaminated by the pet feces

Engineering Contradiction:
Improvewaste collectionVSAvoidcontamination
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies the disposable bag principle to prevent contamination by placing the waste collection function entirely within a disposable bag that is discarded after use. The bag acts as a barrier between the waste and the vacuum device, ensuring that only the bag becomes contaminated, not the vacuum cleaner itself. This resolves the contradiction by sacrificing the bag (disposable) to protect the main device from contamination.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent applies the intermediary principle by using the disposable bag as a mediator between the pet waste and the vacuum cleaner. The bag receives and contains the waste, preventing direct contact with the vacuum device components. This intermediary layer allows effective waste collection while preventing contamination of the vacuum cleaner, resolving the contradiction between productivity and harmful factors.

Inventive Principle:
Principle #24Intermediary (Mediator)
