Dust Collector Handle-Cover Layout for Compact Battery Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dust collecting devices face challenges in handling and battery attachment due to increased product size when both a handle and a cover are provided, making it difficult to attach and detach batteries efficiently.
Innovation Solution
A dust collecting device design where a handle can be raised and turned down around a handle rotation shaft, and a cover can be opened and closed around a cover rotation shaft, with the cover rotation shaft positioned closer to the grip portion than the handle rotation shaft, allowing for a large opening without increasing product size, and including a battery connection portion and a switch for easy battery attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If both a handle and a cover are provided in the dust collecting device, then the ease of operation is improved, but the product size increases
Solution Approach 1:
The patent combines the handle and cover into a single integrated structure where the cover serves dual functions: protecting the battery compartment and acting as the handle grip. This merging eliminates the need for separate components, maintaining ease of operation while reducing overall product size.
Solution Approach 2:
The cover is designed to perform multiple functions simultaneously: it protects the internal components (battery compartment), serves as the user's grip point (handle function), and provides structural support. This multi-functionality allows the device to maintain operational ease without requiring additional dedicated handle components that would increase size.
2Volume of moving object
If the product size is reduced, then the volume of moving object is improved, but the ease of operation deteriorates due to difficulty in attaching and detaching battery
Solution Approach 1:
The patent segments the cover into a removable or openable section that provides access to the battery compartment. This segmentation allows the battery to be easily attached and detached through a designated opening in the cover, maintaining ease of operation despite the compact overall size of the device.

AI summary
A dust collecting device includes a tank (2) and a main body (3) housing a motor (11) and detachably attachable to an upper part of the tank (2). A handle (31) and a cover (58) are both provided in an upper part of the main body (3). The handle (31) is capable of being raised and turned down around a handle rotation shaft (32). The cover (58) is capable of being opened and closed around a cover rotation shaft (61) and covers a housing portion (36) provided in the main body (3) in a closed position. The cover rotation shaft (61) is provided in parallel to the handle rotation shaft (32). The cover rotation shaft (61) is positioned closer to a grip portion (G) of the handle (31) than the handle rotation shaft (32) so as to overlap with a part of the handle (31). The handle rotation shaft (32) is positioned closer to the cover (58) than the cover rotation shaft (61) so as to overlap with a part of cover (58).
