Solution Overview

Problem

Vacuum cleaners with high suction power experience high vacuum pressure between the cleaning head and the surface, leading to adhesion issues and reduced efficiency in dust collection, making it difficult for users to perform effective cleaning.

Innovation Solution

A cleaning head design with three separate suction ports and channels, including a movable lid mechanism that allows for adjustable vacuum pressure distribution, prevents adhesion by allowing air to escape through an orifice, enhancing dust collection and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If high suction power is used to improve dust collection capacity, then dust collection performance is improved, but vacuum pressure increases causing the cleaning head to adhere to the surface

Engineering Contradiction:
Improvedust collection capacityVSAvoidease of movement
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The suction system is segmented into multiple independent suction ports (first suction port and second suction port) with separate channels leading to the pipe. This segmentation distributes the vacuum pressure across multiple entry points, preventing excessive pressure concentration at any single location, thereby reducing adhesion to the surface while maintaining overall dust collection capacity.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a single suction port is used to simplify the structure, then device complexity is reduced, but vacuum pressure distribution becomes non-uniform causing adhesion

Engineering Contradiction:
Improvestructure complexityVSAvoidvacuum pressure distribution
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

Instead of using a single suction port, the invention divides the suction system into multiple ports (first suction port and second suction port) with separate channels. This segmentation creates more uniform vacuum pressure distribution across the cleaning head base, preventing adhesion to the surface while maintaining relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the orifice is always open to prevent adhesion, then ease of operation is improved, but dust collection efficiency decreases due to pressure loss

Engineering Contradiction:
Improveease of movementVSAvoiddust collection efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The orifice is equipped with a movable lid that can be opened or closed by the user. This dynamic configuration allows the user to adjust the system based on cleaning needs: closing the lid during normal dust collection to maintain efficiency, and opening it when adhesion becomes problematic. The movement mechanism enables easy transition between states.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If multiple suction ports are used to homogenize vacuum pressure, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improvevacuum pressure homogeneityVSAvoidnumber of suction ports
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning head incorporates multiple suction ports (first suction port and second suction port) with separate channels, segmenting the suction system to achieve more uniform vacuum pressure distribution across the base. This segmentation improves ease of operation by preventing adhesion, while the modular design keeps the overall complexity manageable.

Inventive Principle:
Principle #1Segmentation
