Oscillating Tool Accessory Plate for Hard-to-Reach Corner Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power-driven oscillating tools face limitations in accessing and effectively completing tasks due to installation environments, workpiece attributes, and accessory design constraints, often requiring multiple accessories or manual intervention for difficult-to-reach areas.
Innovation Solution
An accessory tool with a plate portion featuring distinct working sections, including convexly curved and straight edges, and a notch, allowing for differentiated cutting and abrading capabilities and improved access to hard-to-reach areas without the need for multiple accessories or manual removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single accessory tool is used, then device complexity is reduced, but the ability to access difficult-to-reach areas and perform different cutting tasks is limited
Solution Approach 1:
The accessory tool is segmented into multiple working sections with different edge geometries (convexly curved, straight, concavely curved) positioned at different locations on the plate. Each section can be selectively positioned against the workpiece to access different areas and perform different cutting tasks, allowing one accessory to replace multiple traditional accessories.
Solution Approach 2:
The accessory tool is designed as a universal multi-functional device where a single plate with multiple working sections can perform various cutting operations (convex cutting, concave cutting, straight cutting) and access different geometries (internal corners, external corners, flat surfaces). This multi-functionality eliminates the need for multiple specialized accessories.
2Adaptability or versatility
If multiple accessories are used to access difficult areas, then task completion capability is improved, but device complexity and operation time increase
Solution Approach 1:
The accessory tool allows dynamic selection of working sections during operation. The operator can rotate or reposition the plate to bring different working sections (convex, straight, concave edges) into contact with the workpiece as needed, enabling seamless transition between different cutting tasks without removing or changing accessories.
Solution Approach 2:
Multiple working sections with different geometries are pre-configured on a single accessory tool before operation begins. This preliminary arrangement of diverse cutting edges allows the operator to immediately access different workpiece areas and perform different tasks without the time-consuming process of swapping accessories during operation.
3Device complexity
If traditional single-edge accessories are used, then accessory simplicity is maintained, but access to internal corners and difficult areas is limited
Solution Approach 1:
The accessory tool incorporates asymmetric working sections with different geometries (convex, straight, concave edges) positioned at specific locations on the plate. This asymmetric design allows each section to be optimized for specific tasks (e.g., convex for external corners, concave for internal corners), improving ease of access to various workpiece areas while maintaining a relatively simple overall structure.

AI summary
An accessory tool for a power-driven oscillating tool may include a plate, with a first working section defined along a first peripheral edge portion of the plate, and a second working section defined along a second peripheral edge portion of the plate. The first and second working sections may define cutting or abrading or chipping sections of the accessory tool. The first and second working sections may be separated by a notch formed in a third peripheral edge portion of the plate. Corner portions of the first working section and the second working section may be defined where the first and second working sections meet respective edge portions of the notch, allowing the corner portions to be inserted into and engaged in corresponding corner portions of channels for removal of material from the corner portions of the channels.
