Solution Overview

Problem

Existing cyclone vacuum cleaners face challenges in maintaining optimal sealing between the suction container and the device body during operation, leading to air leakage and requiring significant effort for engaging and disengaging seals.

Innovation Solution

A vacuum cleaner design featuring a parallel airflow path between the suction channel and air channel, aligned with the movement axis, utilizing conical nozzles and pre-filters with locking cams and geometries that create a strong seal through negative pressure, allowing easy attachment and detachment without additional force.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a canister vacuum cleaner is used, then powerful suction is achieved, but the cleaner becomes difficult to maneuver and requires two hands to operate

Engineering Contradiction:
Improvesuction powerVSAvoidmaneuverability
Core Design Contradiction:
PowerVSEase of operation

Solution Approach 1:

The vacuum cleaner is divided into separate functional modules: a handheld cleaning unit with motor and cyclone separator, and a removable dust cup. This segmentation allows the powerful suction mechanism to be concentrated in a compact handheld unit while enabling one-handed operation and easy maneuverability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dust cup is designed to be removably attached to the bottom of the cleaning unit, allowing dust collection in a vertical dimension rather than requiring horizontal expansion. This dimensional change enables powerful suction with a compact, maneuverable form factor.

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

2Adaptability or versatility

If a canister vacuum cleaner with hose and attachments is used, then versatile cleaning capability is achieved, but the cleaner requires assembly and disassembly of parts and storage space

Engineering Contradiction:
Improvecleaning versatilityVSAvoidassembly requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handheld cleaning unit is designed as a universal platform that can perform multiple cleaning functions directly, eliminating the need for separate hose attachments. The motorized brush roll, cyclone separator, and adjustable dust cup capacity provide versatile cleaning capability in a single integrated unit.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The motor, cyclone separator, and dust cup are merged into a single handheld unit that can be used immediately without assembly. The dust cup attaches directly to the bottom of the cleaning unit, eliminating the need for separate hose connections and attachment assemblies.

Inventive Principle:
Principle #5Merging (Combining)

3Quantity of substance

If a canister vacuum cleaner is used, then dust collection capacity is achieved, but the cleaner requires emptying the canister and creates waste

Engineering Contradiction:
Improvedust collection capacityVSAvoidwaste generation
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The dust cup is designed to be completely removable from the cleaning unit, allowing users to easily empty and reuse it multiple times. This recoverable design eliminates the need to discard the dust collection container after a single use, reducing waste while maintaining adequate dust collection capacity.

Inventive Principle:
Principle #34Discarding and recovering

4Ease of operation

If a handheld vacuum cleaner is used, then ease of maneuverability is achieved, but suction power is reduced

Engineering Contradiction:
ImprovemaneuverabilityVSAvoidsuction power
Core Design Contradiction:
Ease of operationVSPower

Solution Approach 1:

A cyclone separator is used instead of traditional filtration systems, utilizing centrifugal force generated by rotating airflow to separate dust from air. This pneumatic separation method is more efficient and allows for higher suction power in a compact handheld design.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The dust cup capacity can be adjusted by removing additional cups from the stackable configuration, allowing users to optimize the balance between dust collection capacity and maneuverability. The motorized brush roll provides consistent suction power across varying operating conditions.

Inventive Principle:
Principle #35Parameter changes
