Solution Overview

Problem

Existing vacuum cleaners require users to bend down to separate the housing and suction head, making it inconvenient to clean under furniture and potentially causing the housing to separate from the suction head during use.

Innovation Solution

A cleaner design featuring a rotatable neck with a switch device on one side, allowing the housing to be easily separated from the suction head without bending, and a rotating body that locks the switch device in place when the neck is inclined, preventing unintended separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the switch is provided on an upper portion of the suction head to allow easy operation, then the user can operate without bending, but the upper portion of the head protrudes which causes inconvenience to clean spaces under furniture

Engineering Contradiction:
Improveease of separationVSAvoidcleaning capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The switch device is extracted from the suction head and placed on the rear surface of the housing, eliminating the protrusion issue while maintaining ease of operation through foot step activation

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If the neck is rotatable to allow flexible positioning, then the cleaner can adapt to different cleaning scenarios, but the housing may easily separate from the suction head during use

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The locking member is designed to automatically engage with the switch device when the neck is in the inclined position, preventing unintended separation by counteracting the rotational force before it can cause detachment

Inventive Principle:
Principle #9Preliminary anti-action

Applied Scientific Principles

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

Function Achieved in This Case

Enables easy separation of the housing from the suction head without bending, prevents accidental separation during use, and improves aesthetics.

Implementation Method 1

a rotating body rotatably couplable to the neck and configured to lock the switch device while the neck is at a first position with respect to the suction head and unlock the switch device while the neck is at a second position with respect to the suction head

Methodology Applied
Scientific EffectGravity: Gravitation
