Backpack Dust Collector Side-Mounted Battery Access for Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Backpack dust collectors with battery mounting portions face challenges in smoothly mounting and removing batteries due to design limitations, which affect operational efficiency and user convenience.
Innovation Solution
The design includes strategically positioned battery openings on the left and right side surfaces of the housing, along with guide rails and a moving mechanism that facilitates easy insertion and removal of batteries, utilizing inclined guide rails and elastic members to assist in the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery mounting portion is designed with conventional structure, then the housing structure is simple, but the battery cannot be mounted and removed smoothly
Solution Approach 1:
The battery opening is divided into multiple sections: an inclined upper section that guides battery insertion, and a lower section that receives the battery. This segmentation allows the battery to be smoothly guided into position while maintaining a relatively simple overall housing structure.
Solution Approach 2:
The battery opening incorporates an inclined surface element that adds a directional component to the insertion path. This dimensional change from a simple horizontal opening to an inclined-path opening facilitates smooth battery mounting and removal without requiring complex mechanical mechanisms.
2Ease of operation
If the battery opening is positioned conventionally, then the housing design is straightforward, but user accessibility is reduced
Solution Approach 1:
The battery opening is positioned asymmetrically on the side surface of the housing rather than centrally or symmetrically. This asymmetric placement improves user accessibility when wearing the backpack, allowing easy reach to the battery compartment without requiring symmetric design constraints.

AI summary
A backpack dust collector includes a housing. The housing includes: a suction port; a dust collecting chamber connected to the suction port and configured to accommodate a dust collecting bag; a motor chamber connected to the dust collecting chamber and accommodating a fan and a motor; an exhaust port through which air from the motor chamber is discharged; first and second battery openings; and first and second battery receiving portions respectively corresponding to the first and second battery openings. At least part of the first battery opening is formed on a left side surface of the housing, and at least part of the second battery opening is formed on a right side surface of the housing.
