Solution Overview

Problem

Existing vacuum cleaners face challenges in maintaining efficient suction performance and user convenience due to high flow path resistance and cumbersome controller designs, particularly in cordless models, which affect battery efficiency and ease of maintenance.

Innovation Solution

A detachable controller design for vacuum cleaners that allows for backward separation of the filter housing, reduces flow path resistance, and enables interchangeable controllers with various designs to enhance user convenience and maintainability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the controller is integrated into the main body, then the structure is compact and simple, but the filter housing cannot be detached backward and maintenance is difficult

Engineering Contradiction:
Improvefilter housing detachabilityVSAvoidcontroller structure
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The controller is separated from the main body and placed on the filter housing, allowing the filter housing to be detached independently for maintenance. This segmentation enables the filter housing to be removed backward without the controller interfering, while keeping the overall structure relatively simple.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the controller is placed on the filter housing, then the filter housing can be detached backward, but the controller interferes with the detachment movement

Engineering Contradiction:
Improvefilter housing detachabilityVSAvoiddetachment movement
Core Design Contradiction:
Ease of repairVSEase of operation

Solution Approach 1:

The controller is positioned on the filter housing in such a way that it can be detached along with the filter housing. The controller's attachment mechanism is designed to move in the same backward direction as the filter housing detachment, eliminating interference with the detachment movement.

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

3Force

If the flow path resistance is high, then the suction force is strong, but the battery consumption increases and cleaning time decreases

Engineering Contradiction:
Improvesuction forceVSAvoidbattery consumption
Core Design Contradiction:
ForceVSUse of energy by moving object

Solution Approach 1:

The dust collector is designed to efficiently separate foreign substances from the air flow, reducing the resistance to air flow. By effectively removing dust particles, the system maintains strong suction force while minimizing the energy required to move air through the system, thus reducing battery consumption.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A cleaner includes a main body and a controller configured to control an operation of the cleaner. The main body may be provided with a suction fan to generate a suction force for sucking in air, a dust collector to separate foreign substances from the sucked-in air, and a filter housing supporting a filter to filter foreign substances out of the air that has passed through the dust collector and the suction fan. The controller is located at the rear of the filter housing. The controller is detachable from the main body.
