Solution Overview

Problem

Conventional vacuum cleaners have small dust bins that require frequent emptying, leading to health hazards, reduced suction power, and unpleasant odors due to residual dust, and existing solutions with door motors are complex and prone to failure.

Innovation Solution

A cleaner station with a simple structure that includes a cover control unit to manually close the discharge cover, utilizing a button, link, and elastic body to rotate a cover control frame, eliminating the need for motors and additional components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a door motor is used to automatically open and close the discharge cover, then the automation level is improved, but the device complexity and cost increase due to additional parts such as encoders

Engineering Contradiction:
Improveautomatic discharge cover operationVSAvoidnumber of parts
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent extracts and removes the motor from the door unit, keeping only the essential mechanical linkage components (link and cover control frame). This eliminates the complex electrical components while maintaining the core automatic opening function through simplified mechanical means.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The door unit is designed to automatically open the discharge cover using the weight and movement of the dust bin itself, without requiring an external motor. The mechanical linkage leverages the natural movement of components during dust bin removal to automatically open the cover.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If a door motor is used to precisely rotate the link, then the measurement precision is improved, but the device complexity increases due to additional components such as encoders

Engineering Contradiction:
Improvelink rotation detectionVSAvoidnumber of parts
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The encoder and motor are completely removed from the system. The patent achieves sufficient control precision through simple mechanical linkages and geometric relationships between components, eliminating the need for electronic sensors and feedback systems.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If a door motor is used to close the discharge cover, then the ease of operation is improved, but the reliability decreases when the motor malfunctions

Engineering Contradiction:
Improvedischarge cover closingVSAvoiddoor unit functionality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the expensive and complex motor with simple, inexpensive mechanical components that are inherently more reliable. The link and cover control frame are basic mechanical elements with no moving parts that could fail electronically, making the system more robust against malfunctions.

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

4Object-affected harmful factors

If the door unit is positioned to close the dust passage hole, then the dust containment is improved, but the productivity decreases when the door motor fails and cannot open the cover

Engineering Contradiction:
Improvedust dispersionVSAvoiddust collection efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The door unit automatically opens the discharge cover when the dust bin is removed from the cleaner body, without requiring motor actuation. This self-activating mechanism ensures that dust collection can proceed immediately when the bin is in place, eliminating delays caused by motor failure.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
