Hand-held vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held vacuum cleaners are not versatile enough, requiring users to choose between stick and trunk models based on usage and surface type, and face installation and handling issues due to large handles and space constraints.
Innovation Solution
A hand-held vacuum cleaner design with a modular configuration allowing the housing body to have sockets at both ends, enabling the suction tube, handle, and floor nozzle to be connected in multiple configurations, reducing handle size and optimizing space usage by eliminating the need for a sleeve inside the device body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device body has a sleeve inside to receive another vacuum cleaner component, then the connection is secured, but the installation space is reduced and the device body becomes larger
Solution Approach 1:
Instead of having the device body contain a female element (sleeve) to receive male elements from other components, the invention inverts the design: the device body has male elements at its ends, and the other components (suction tube, handle, floor nozzle) have female elements. This inversion eliminates the need for internal sleeves in the device body, reducing its volume while maintaining secure connections.
2Reliability
If the handle is made large to accommodate connection components, then the connection is secured, but the handle requires more space and becomes less ergonomic
Solution Approach 1:
The handle's connection design is inverted: instead of containing a female element to receive a male element from the suction tube, the handle has a male element that connects to a female element on the suction tube. This allows the suction tube's female element to extend into the handle, securing the connection without requiring the handle to be enlarged, thus maintaining ergonomic dimensions.
Solution Approach 2:
The suction tube's female element is nested into the handle's male element, creating a secure connection where one component fits inside the other. This nesting arrangement secures the connection while keeping the handle compact and ergonomic.
3Device complexity
If the vacuum cleaner has fixed configuration, then the structure is simple, but the versatility and flexibility of use is reduced
Solution Approach 1:
The device body is designed with identical male elements at both ends, making it universal and interchangeable. This allows the vacuum cleaner components to be arranged in multiple configurations (handle at either end), providing versatility and flexibility without significantly increasing structural complexity. The symmetric design enables the same body to function equally well in either orientation.
