Solution Overview
Problem
Existing abrasive blasting devices, particularly in dental technology, face challenges in providing simple and convenient operation for generating and controlling abrasive jets, often requiring mechanical shut-off mechanisms that are cumbersome and not efficiently powered.
Innovation Solution
The integration of a pneumatic fluid power unit with a release unit that uses a control fluid to generate forces for activating and blocking the abrasive fluid, allowing for efficient and easy operation by reducing the need for manual force and incorporating a pinch valve design for precise control and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical shut-off means are used for the abrasive stream, then the device structure is simple, but the operation is cumbersome and requires manual force
Solution Approach 1:
The patent replaces the purely mechanical shut-off means with a pneumatic fluid power unit that uses compressed air to generate the blocking force. The release unit is actuated by a control fluid (air) that generates force through a piston mechanism, eliminating the need for manual mechanical operation while maintaining structural simplicity through the integration of pneumatic components into the existing abrasive blasting system
Solution Approach 2:
The patent introduces a pneumatic fluid power unit that uses compressed air as the working medium. The control fluid (air) is supplied through a control line to the release unit, where it generates force to actuate the shut-off mechanism. This pneumatic system provides effortless operation while the integrated design keeps the overall structure compact and simple
2Productivity
If manual force is applied to activate the release unit, then the device structure is simple, but the operator effort is high and activation is slow
Solution Approach 1:
The patent replaces manual mechanical actuation with a pneumatic power unit that uses compressed air to generate the necessary force. The control fluid (air) is supplied through a control line to the release unit, where it generates force to actuate the shut-off mechanism instantly, eliminating operator effort and enabling rapid activation and deactivation of the abrasive stream
Solution Approach 2:
The pneumatic system is pre-charged with compressed air through the control line, so that when the release unit is actuated, the force is immediately available without requiring operator effort. The control fluid is ready in advance to provide the necessary force for instantaneous activation, improving productivity while eliminating the need for manual force application
