Dust Collector Handle-Cover Layout for Larger Battery Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dust collecting devices with both a handle and a cover for battery attachment face challenges in maintaining a large opening size, making it difficult to attach and detach the battery without increasing the product size.
Innovation Solution
The design includes a handle that can be raised and turned down around a handle rotation shaft, and a cover that can be opened and closed around a cover rotation shaft, positioned closer to the grip portion than the handle rotation shaft, allowing for a larger opening without increasing the device's size, facilitating 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 upper part of the main body, then the handle facilitates movement and the cover protects the battery housing portion, but the product size increases
Solution Approach 1:
The cover rotation shaft is positioned closer to the grip portion of the handle than the handle rotation shaft, causing the cover rotation shaft to overlap with a part of the handle. This spatial overlapping in three-dimensional space allows the cover to achieve a large opening area without increasing the product's external dimensions, as the cover utilizes the vertical and depth dimensions created by the handle's position.
2Volume of moving object
If the product size is reduced, then the product becomes more compact, but the cover size is reduced making it difficult to form a large opening for battery attachment and detachment
Solution Approach 1:
By positioning the cover rotation shaft to overlap with the handle in three-dimensional space, the cover can achieve a large opening area without increasing the product's external dimensions. This allows the opening to be sufficiently large for easy battery attachment and detachment while maintaining a compact product size.
3Area of stationary object
If the cover rotation shaft is positioned closer to the grip portion than the handle rotation shaft, then the cover can have a large opening without increasing product size, but the handle and cover structures become more complex
Solution Approach 1:
The cover rotation shaft and handle rotation shaft are positioned to overlap in space, causing the cover and handle structures to intersect and share the same spatial region. This merging of structures allows the cover to achieve a large opening area without requiring additional space or increasing product dimensions, as the two components utilize the same structural space.

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