Handheld Vacuum Component Layout to Balance Grip Space and Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld electric vacuums face operability and workability issues due to the heavy weight distribution of components like the blower fan and battery, which can lead to increased load on the operator and reduced grip space, potentially making the structure more complicated or larger.
Innovation Solution
The handheld electric vacuum optimizes component placement by inclining the blower fan forward and positioning the battery oppositely to the handle, creating a larger grip space while maintaining balance, with the handle disposed between the upper and lower sides of the blower fan and battery, and integrating a pressure flow path that extends from the blower fan to the suction port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blower fan and battery are disposed near the handle, then the load on the operator is reduced, but the space around the grip portion is narrowed
Solution Approach 1:
The patent applies dimensional arrangement by disposing the blower fan and battery in different spatial dimensions relative to the handle. The blower fan is positioned at the front end of the pipe while the battery is positioned at the base end, creating a distributed longitudinal arrangement that optimizes both grip space and weight balance without requiring increased device size.
2Area of stationary object
If the blower fan and battery are disposed at positions spaced from the handle, then the grip space is ensured, but the operation balance is degraded
Solution Approach 1:
The patent segments the heavy components (blower fan and battery) and distributes them to different locations along the pipe structure. The blower fan is disposed at the front end while the battery is disposed at the base end, creating a balanced weight distribution that maintains operational balance while preserving adequate grip space around the handle.
3Ease of operation
If the components are arranged to ensure grip space, then the operability is improved, but the device structure becomes more complicated or larger
Solution Approach 1:
The patent merges the handle structure with the support structure for the blower fan and battery. The handle is integrated into the pipe assembly such that it naturally provides structural support while maintaining clear grip space, eliminating the need for additional separate support components and reducing overall structural complexity.
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
This configuration improves operability and workability by ensuring a spacious grip area without increasing the device's complexity or size, allowing for balanced operation even with heavy components positioned near the handle.
Implementation Method 1
The pressurized wind ejected from the ejector passes through the inside of the pipe along the inner surface of the pipe and is ejected to the discharge port. This pressurized wind causes the pressure inside the pipe to be lowered, thereby to generate suction flow (negative pressure) in the pipe from the suction port toward the discharge port.

AI summary
Provided is a handheld electric vacuum capable of improving the operability and workability while reducing the likelihood of the structure becoming more complicated or larger by optimizing the layout configuration around a handle, including a blower fan, a casing, and a battery. The blower fan 20 is inclined forwardly along a bending portion 10T and disposed on the base end side of the bending portion 10T provided at the base end of the pipe 10. In addition, an opposing portion (vertical side portion 30C) of the handle 30 incorporating the battery 50, facing the blower fan 20 is inclined (inclined backwardly) oppositely to the blower fan 20. The upper length (near a grip portion) of a space 30S of the handle 30 formed on the base end side of the blower fan 20 is greater than the lower length thereof.
