Handheld Vacuum Cleaner Battery Layout for Better Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld cleaners with power supply devices located at the bottom of the handle are bulky and uncomfortable to hold due to their weight and volume, making them inconvenient for users.
Innovation Solution
The power supply device is positioned at the top of the handle casing, within the handle assembly, and the negative pressure device is housed in the dust cup assembly, balancing the gravity center and improving handholding comfort and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply device is disposed at the bottom of the handle, then the handle has a large volume and great weight, but this makes it inconvenient for users to hold and use
Solution Approach 1:
The patent inverts the conventional placement of the power supply device from the bottom of the handle to the top of the handle. This inversion changes the gravity center position, making the handle lighter and more comfortable to hold while still maintaining reliable power supply to the negative pressure device through electrical connection
2Reliability
If the power supply device is disposed at the bottom of the handle, then the handle has a large volume, but this increases the overall size and reduces portability
Solution Approach 1:
By inverting the power supply device placement from bottom to top of the handle, the patent reduces the handle volume and improves portability. The electrical connection between the power supply device and negative pressure device ensures that power supply reliability is maintained despite the changed position
