Oscillating Tool Anchor Interface for Stable Accessory Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillating power tools lack an efficient and secure interface for coupling accessories, leading to instability and reduced performance during operation.
Innovation Solution
A novel anchor interface design featuring a central aperture and radially disposed peripheral openings, with conjoined groups of openings connected by shared neck openings, provides a secure and stable attachment mechanism for oscillating power tools and accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional coupling interface is used for accessories, then the device complexity is low, but the stability and reliability of accessory attachment deteriorates
Solution Approach 1:
The coupling interface is segmented into multiple functional components: a central aperture for primary attachment, multiple peripheral openings for secondary attachment points, and conjoined groups of openings for distributed fastening. This segmentation allows each component to serve a specific function, improving overall attachment reliability while keeping the design modular and manageable.
Solution Approach 2:
Multiple peripheral openings are merged into conjoined groups that are collectively in communication with the central aperture through shared neck openings. This merging creates a unified attachment system where fasteners can engage multiple openings simultaneously, enhancing stability without requiring separate independent mechanisms for each opening.
2Adaptability or versatility
If multiple peripheral openings are provided for accessory coupling, then the adaptability and versatility improve, but the device complexity increases
Solution Approach 1:
The central aperture and peripheral openings form a universal coupling interface that can accommodate various accessory types and fastening configurations. The same interface structure serves multiple functions: primary attachment through the central aperture, secondary attachment through peripheral openings, and distributed fastening through conjoined groups, making it adaptable to different accessory requirements without needing multiple specialized interfaces.
Solution Approach 2:
Different regions of the coupling interface have specialized characteristics: the central aperture provides a primary attachment point with direct access, while peripheral openings are strategically positioned and grouped to provide secondary attachment points. The conjoined groups of openings with shared neck openings create localized attachment zones that offer enhanced stability for specific fastening patterns, allowing each region to optimize its function while contributing to the overall versatility of the interface.

AI summary
An accessory for an oscillating power tool includes an anchor for selectively coupling with an oscillating power tool. The anchor includes a generally planar portion having an anchor interface configured to couple to the oscillating power tool and defining a longitudinal axis and a center point. The anchor interface includes a central aperture and a plurality of peripheral openings. The central aperture includes the center point therein. The plurality of peripheral openings are disposed radially about the center point and in communication with the central aperture. The plurality of peripheral openings also includes at least one conjoined group of peripheral openings collectively in communication with the central aperture by way of a shared neck opening. The at least one conjoined group includes a first peripheral opening, a second peripheral opening, and a third peripheral opening.
