Rotatable Neck Vacuum Cleaner with Gravity-Locked Switch
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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

AI summary
A cleaner includes a housing provided to receive a fan motor unit configured to generate a suction force and a dust collecting chamber provided to collect foreign substances, a suction head coupled to a lower portion of the housing to suck the foreign substances on a surface to be cleaned, a neck arranged between the suction head and the housing to connect the suction head to the housing, the neck rotatable with respect to the suction head and detachably coupled to the housing, a switch device arranged on one side of the neck to allow the neck and the housing to be coupled to each other or separated from each other, and a rotating body rotatably coupled to the neck and configured to lock or unlock the switch device according to a position of the neck with respect to the suction head.
