Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oscillating power tools have diverse accessory attachment mechanisms, leading to compatibility issues across different brands, making it difficult to use accessories with various clamping devices.
Innovation Solution
The development of a universal mounting interface for oscillating power tool accessories, featuring a spindle slot and pin openings with a non-rectangular profile, allowing the accessory to be securely attached to a wide range of clamping devices regardless of brand or manufacturer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a proprietary accessory attachment mechanism is used for each brand, then the reliability of the attachment is improved, but the adaptability to different clamping devices deteriorates
Solution Approach 1:
The accessory mounting interface is designed with a universal configuration that can be attached to multiple different clamping devices from various manufacturers. The mounting portion includes a spindle slot and pin openings arranged in a standardized pattern that accommodates different spindle and pin configurations, allowing one accessory design to serve multiple functions across different tool brands.
2Adaptability or versatility
If multiple different attachment schemes are developed, then the adaptability to different accessories is improved, but the device complexity deteriorates
Solution Approach 1:
The mounting interface is segmented into distinct functional elements: a spindle slot for receiving the tool spindle, multiple pin openings for receiving alignment pins, and clamping surfaces. This segmentation allows each element to be optimized independently while maintaining overall simplicity and compatibility with various attachment schemes.
3Adaptability or versatility
If a non-rectangular pin opening profile is used, then the adaptability to different pin configurations is improved, but the manufacturing precision requirements deteriorate
Solution Approach 1:
The pin openings are designed with asymmetric, non-rectangular profiles that can accommodate different pin diameters and positions. The irregular geometry provides tolerance compensation that reduces the stringency of manufacturing precision requirements while ensuring proper alignment and secure attachment across various pin configurations.

AI summary
An accessory for a power tool includes a mounting interface for detachably mounting the accessory to a clamping device of the power tool. The mounting interface is configured to permit the accessory to be used with a wide variety of clamping devices, regardless of manufacturer. The accessory includes a mounting portion having a spindle slot configured to accommodate a drive spindle of the tool and pin openings that are arranged around the spindle slot. The pin openings are configured to receive pins which are arranged around a spindle of an oscillating power tool. When viewed in a cross section that is perpendicular to the first clamping face, at least a portion of opposed surfaces of at least one pin opening are non-parallel.
