Handy-stick type vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handy-stick type vacuum cleaners require users to twist their wrists and arms to change direction, leading to fatigue due to a fixed handle position, and they struggle to easily discharge human or pet hairs from the dust collecting member.
Innovation Solution
A handy-stick type vacuum cleaner design featuring a rotatable handle system connected via a flexible tube, allowing the dust collecting member and suction motor to be positioned at various angles, and a mechanism for efficiently discharging hairs through a helical guide and grill filter member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is fixed to the main body, then the structure is simple and stable, but the user must twist the wrist or arm to change cleaning direction, causing fatigue
Solution Approach 1:
The handle is made rotatable relative to the main body through a rotation mechanism, allowing the user to adjust the handle angle dynamically during cleaning operations. This dynamic adjustment eliminates the need to twist the wrist or arm, directly resolving the contradiction between operational comfort and structural simplicity.
2Ease of operation
If the dust collecting member is fixed, then the structure is stable, but human hairs or pet hairs are difficult to discharge from the dust collecting member
Solution Approach 1:
The dust collecting member is made rotatable relative to the main body, allowing it to rotate to a discharge position where hairs can be easily removed. This dynamic capability enables users to access and discharge accumulated hairs without disassembling the device, resolving the contradiction between structural stability and ease of hair discharge.
