Oscillating Blade Snap-Fit Arbor for Multi-Tool Torque Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillating blades are not universally adaptable to various oscillating power tool designs due to dedicated anchor shapes, leading to inefficiencies in torque transfer and compatibility issues across different tool manufacturers.
Innovation Solution
The oscillating blade features a tool arbor engagement portion with a side wall and cap wall, configured for a snap fit engagement with a power tool connection clamp, including a central arbor hole and arbor opening, allowing for attachment to a variety of tool designs and enhancing torque transfer efficiency.

Engineering Contradiction Analysis
1Ease of manufacture
If traditional anchor designs are used, then manufacturing simplicity is maintained, but torque transfer efficiency deteriorates
Solution Approach 1:
The anchor portion incorporates a spring-loaded arm that can deflect and return, providing dynamic torque transfer. The spring arm flexes under torque load and returns to its original position, creating a resilient connection that improves torque transfer efficiency while maintaining manufacturing simplicity through the use of elastic deformation

AI summary
An oscillating power tool includes a power tool connection clamp and an oscillating saw blade. The power tool connection clamp defines a clamp recess. The oscillating saw blade includes an anchor, a working portion, a tool arbor engagement portion, and a tool arbor lock point. The anchor is disposed at least partially in a first plane. The tool arbor engagement portion includes a side wall extending away from the first plane and a cap wall coupled to the side wall and disposed at least partially in a second plane. The tool arbor lock point extends outwardly from the side wall between the first plane and the second plane. The tool arbor lock point is configured to mate with the power tool connection clamp in a snap fit engagement when received in the clamp recess.
