Upright Vacuum Cleaner Steering Nozzle for Easier Direction Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Upright vacuum cleaners require significant user effort and strain to change the moving direction due to the need for manual rotation of the suction nozzle, leading to labor-intensive operation.
Innovation Solution
Incorporation of a suction nozzle with multiple wheels and a steering device that allows the main body to be relatively rotatable, enabling the transmission of rotation force to the wheels for easy direction change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suction nozzle is manually rotated to change moving direction, then the user can control the cleaner's direction, but the user's wrist may be strained and lots of labor is required
Solution Approach 1:
The suction nozzle is made rotatable relative to the main body through a rotation mechanism, allowing dynamic direction adjustment without manual wrist rotation. The connection device enables the suction nozzle to rotate freely while maintaining connection, transforming the static rigid connection into a dynamic adjustable one.
Solution Approach 2:
A connection device acts as an intermediary between the main body and suction nozzle, providing a rotation mechanism that mediates the force transmission. This intermediary allows directional change with reduced force by enabling rotational movement at the connection point.
2Ease of operation
If the suction nozzle is rotatably connected to the main body, then the moving direction can be changed more easily, but the structure becomes more complex
Solution Approach 1:
The connection device is divided into separate components including a rotation mechanism and connection elements, allowing the rotational function to be added without complicating the entire structure. The segmentation enables independent optimization of each component.
Solution Approach 2:
The connection device serves as an intermediary structure that introduces rotational capability with minimal complexity addition. It provides the necessary rotation function while maintaining a relatively simple overall structure through its design as a dedicated connection component.
