Power Tool Dust Cover Segmented Protrusion Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust covers for power tools are difficult to attach and detach, leading to reduced operability due to elastic deformation, time-consuming detachment with hooks, or deformation of rubber frames, which complicates maintenance and usage.
Innovation Solution
A dust cover with a plate-like design featuring deformable protrusions and undercuts on rails that slide into receivers, providing sliding resistance for secure attachment and effortless detachment, ensuring easy operation and preventing accidental slipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dust cover is attached using elastic force with two ends engaged with a tool body, then the dust cover can be securely attached, but the operability for attachment and detachment is lowered due to the need to deform against elastic force
Solution Approach 1:
The dust cover is divided into a plate-like main body and multiple protrusions that are separately formed. The protrusions are inserted into corresponding holes in the tool body, creating discrete attachment points that simplify the attachment process while maintaining secure fixation.
Solution Approach 2:
Instead of using elastic force to hold the dust cover in place, the invention inverts the approach by using fixed protrusions that insert into fixed holes. This reversal eliminates the need to deform the dust cover against elastic force, making attachment and detachment much easier while maintaining reliable fixation.
2Reliability
If engagement tabs with hooks are used to attach the dust cover, then the dust cover can be securely attached, but detachment becomes time-consuming due to the need to disengage hooks
Solution Approach 1:
The attachment mechanism is segmented into multiple independent protrusions distributed around the dust cover perimeter. Each protrusion can be independently inserted into its corresponding hole, allowing for quick attachment without the need to manipulate complex hooked structures.
Solution Approach 2:
The invention replaces the hook-based retention mechanism with a simple insert-into-hole system. Instead of hooks that need to be disengaged, the protrusions are simply inserted into holes, making detachment as easy as pulling the dust cover off, significantly reducing the time required for maintenance.
3Adaptability or versatility
If a dust cover with a rubber frame is used, then the dust cover can be flexibly attached, but detachment becomes time-consuming due to deformation of the rubber frame
Solution Approach 1:
The dust cover structure is segmented into a rigid plate-like body with integrated protrusions. This segmentation eliminates the need for a flexible rubber frame while maintaining attachment capability through the protrusion-hole mechanism, which provides both adaptability and quick detachment.
Solution Approach 2:
Instead of using a deformable rubber frame to achieve flexibility, the invention inverts the approach by using a rigid structure with fixed geometric protrusions. The flexibility is achieved through the design of the protrusion positions and shapes rather than material deformation, enabling both adaptability and quick detachment.

AI summary
A dust cover has improved operability for attachment and detachment. A power tool to which a disk tool is attachable includes an electric motor including a motor shaft, a housing accommodating the electric motor and having an inlet to draw outside air, a dust cover being a plate including a filter covering the inlet and being attachable to and detachable from the housing, a grip extending from the housing in a direction perpendicular to the motor shaft and located between the disk tool and the inlet in a direction in which the motor shaft extends, and a spindle coaxial with the motor shaft, protruding from an end of the housing to receive the disk tool, and rotatable by the electric motor.
