Auxiliary Handle Dust Collection for Impact Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collecting devices for impact tools require a mounting part, which limits their attachment to impact tools without pre-existing mounting facilities.
Innovation Solution
A dust collecting device that attaches to impact tools via an auxiliary handle, utilizing a hose holding part that can be mounted to and removed from the handle, and optionally secured using a clamping mechanism or wrapping member, allowing attachment to tools without dedicated mounting parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dust collecting device is designed with a fixed mounting part, then the device structure is simple and reliable, but it cannot be attached to impact tools without pre-existing mounting facilities
Solution Approach 1:
The auxiliary handle is designed to serve multiple functions: it acts as both the operational handle for the impact tool and as a mounting support for the dust collecting device. The mounting part utilizes the existing auxiliary handle structure, allowing the dust collecting device to be attached to impact tools that previously had no mounting facilities, thereby achieving universality across different tool configurations
Solution Approach 2:
The mounting part acts as an intermediary component that bridges the dust collecting device and the impact tool body. It includes a clamping mechanism with jaws that can grip the auxiliary handle, and a mounting plate that interfaces with the dust collecting device, thereby enabling attachment without requiring modifications to the original tool structure
2Adaptability or versatility
If a dust collecting device is made removable from the auxiliary handle, then the device versatility is improved, but the ease of operation is reduced due to additional mounting and removal steps
Solution Approach 1:
The mounting part incorporates a clamping mechanism with movable jaws that can transition between open and closed states. The jaws are biased by a spring and can be opened by operating a release lever, allowing the auxiliary handle to be inserted or removed. This dynamic mechanism enables quick attachment and detachment without complex tools or procedures
Solution Approach 2:
The clamping mechanism is designed to automatically grip the auxiliary handle when the release lever is actuated, using spring force to maintain clamping pressure. The release lever mechanism allows the user to easily open the jaws by simple manual operation, making the mounting and removal process self-service oriented without requiring additional tools or complex procedures

AI summary
A dust collection device, that collects dust particles generated by an impact tool, has a feature that enables the attachment of the device to the impact tool, which is not provided with an attachment section for the device. The dust collection device has a tool body and an auxiliary handle, attached removably to the tool body, and is attached to an electric hammer that, in the lengthwise direction, linearly operates a tool bit mounted to the tip region of the tool body, and collects dust generated by the electric hammer. The dust collection device has: a dust collection unit that has a dust intake port at the tip; a dust collection hose, connected to the dust collection unit, for transferring dust to the downstream side; and a hose-holding unit that holds the dust collection hose. The hose-holding unit can be attached to and removed from the auxiliary handle.
