Dust Extractor Adaptor Catch for Multi-Drill Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust extractors are designed to be used with only one specific type of hammer drill, limiting their compatibility with different drill designs.
Innovation Solution
An adaptor with a sliding catch mechanism and biasing system that allows the dust extractor to be securely attached to various hammer drills, including those with different motor housing lengths, by engaging and disengaging the catch mechanism to accommodate different drill configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dust extractor is designed for a specific hammer drill model, then the attachment is secure and reliable, but the adaptability to different drill designs is limited
Solution Approach 1:
The adaptor housing is designed with a standardized interface that can accommodate multiple hammer drill models with different motor housing lengths. The universal design allows the same adaptor to work with various drill configurations, achieving multi-functionality and broad compatibility without compromising attachment security
Solution Approach 2:
The adaptor catch is designed to be movable between engaged and disengaged positions, allowing dynamic adaptation to different drill models. The catch can be manually positioned to accommodate varying motor housing lengths while maintaining secure attachment when engaged, resolving the contradiction between fixed security and flexible adaptability
2Reliability
If the adaptor catch is always in the engaged position, then the dust extractor is securely attached, but the adaptor cannot be removed or changed
Solution Approach 1:
The adaptor catch is designed as a movable component that can be easily shifted between engaged and disengaged positions. This dynamic design allows the user to securely attach the dust extractor by engaging the catch, and just as easily remove or change the adaptor by disengaging the catch, achieving both secure attachment and ease of operation
Solution Approach 2:
The biasing mechanism automatically maintains the catch in the engaged position, providing self-locking functionality. The user only needs to manually disengage the catch to remove the adaptor, and the biasing mechanism will automatically re-engage it upon release, reducing the effort required for both attachment and removal operations

AI summary
An adaptor for a dust extractor is provided including a housing having a top portion and a bottom portion, a first aperture formed in the top portion of the housing, a second aperture formed in the bottom portion of the housing, and an adaptor catch having a first end and a second end. The adaptor catch is vertically slidable within the housing between a first catch position, where the first end projects through the first aperture, and a second catch position, where the first end is located flush with or inside of the housing. The second end of the adaptor catch is accessible through the second aperture. A first biasing mechanism biases the adaptor catch towards the second catch position.
