Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillating power tools lack an efficient mechanism for conveying removed material during material-removing operations, leading to inefficient debris management and potential mess.
Innovation Solution
A blade accessory with a conduit system that integrates with oscillating power tools, allowing for the direct conveyance of removed material to a vacuum system, enhancing debris management and cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional oscillating power tool blade is used without a conduit system, then the device complexity is low, but debris management efficiency deteriorates leading to inefficient material removal and potential mess
Solution Approach 1:
The patent merges the cutting blade and debris conveyance functions into a single integrated accessory. The conduit is formed as an integral part of the blade body, combining the material-removing operation with the debris conveyance system, thereby improving productivity without requiring separate vacuum attachment devices
Solution Approach 2:
The conduit acts as an intermediary element that bridges the cutting edge and the vacuum system. It provides a dedicated pathway for transporting removed material from the cutting zone to the vacuum collection system, enabling efficient debris management while maintaining relatively simple device architecture
2Object-affected harmful factors
If a blade with integrated conduit is used, then operational cleanliness is improved, but the ease of manufacture deteriorates due to more complex manufacturing processes
Solution Approach 1:
The blade body and conduit are merged into a single integral structure, allowing both components to be manufactured simultaneously as one piece. This eliminates the need for separate assembly operations and reduces manufacturing complexity despite the enhanced cleanliness function
Solution Approach 2:
The blade accessory serves multiple functions: cutting/material removal and debris conveyance. By making the blade multi-functional, the patent improves operational cleanliness without requiring additional separate components, thereby maintaining ease of manufacture through universal design
3Loss of time
If material removed during operation is not conveyed away, then the device complexity remains low, but loss of time increases due to frequent stops for debris removal
Solution Approach 1:
The conduit system enables continuous conveyance of removed material throughout the cutting operation. By providing a constant pathway for debris removal, the system maintains uninterrupted cutting action, reducing operational downtime without requiring complex intermittent debris ejection mechanisms
Solution Approach 2:
The blade accessory serves itself by incorporating the conduit system that automatically transports its own debris. The removed material is self-conveyed through the conduit to the vacuum system without requiring external intervention or additional mechanisms, minimizing operational downtime while keeping device complexity low
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The blade accessory effectively directs removed material to a vacuum system, improving operational cleanliness and efficiency by ensuring that debris is managed effectively during material-removing operations.
Implementation Method 1
a conduit extending from proximate the cutting edge towards the attachment portion and configured to convey material removed during the material-removing operation to the vacuum system

AI summary
An accessory for use with an oscillating power tool. The accessory includes an attachment portion including a mounting aperture arrangement configured to couple with the oscillating power tool. The accessory also includes a body extending away from the attachment portion in a longitudinal direction defining a longitudinal axis, a distal end portion including a generally planar surface and a cutting edge configured to perform a material-removing operation, and a conduit extending from proximate the cutting edge towards the attachment portion. The conduit is configured to convey material removed during the material-removing operation towards a vacuum system.
