Solution Overview
Problem
Existing vacuum generating apparatuses with electrically driven primary vacuum generators face challenges in achieving high vacuum levels and energy efficiency, particularly when handling large flow volumes, and are often complex and expensive to improve.
Innovation Solution
A vacuum generating apparatus that combines an electrically driven primary vacuum generator with an ejector apparatus using the jet suction pump principle, where the suction connection of the primary vacuum generator is in flow connection with the outflow opening of the ejector apparatus, allowing for improved vacuum levels and energy efficiency without the need for active pressure-driven suction, and enabling multiple ejector apparatuses to be connected in parallel for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If higher RPMs or improved insulation of blower wheels are used to improve vacuum pressure in electrically driven vacuum generators, then vacuum pressure is improved, but the system becomes technically complex and expensive
Solution Approach 1:
The patent introduces an ejector apparatus as an intermediary device between the primary vacuum generator and the vacuum source. The ejector uses the available primary vacuum to create an enhanced suction effect through jet suction pump principles, allowing improved vacuum pressure without modifying the complex internal components of the primary vacuum generator itself
Solution Approach 2:
The invention utilizes pneumatic principles by employing an ejector apparatus that operates on jet suction pump principles. The ejector uses compressed air or gas flow through a nozzle to create a vacuum effect, combining pneumatic power with the electrically driven primary vacuum generator to achieve higher vacuum levels without increasing electrical motor complexity
2Stress or pressure
If higher RPMs or improved insulation of blower wheels are used to improve vacuum pressure in electrically driven vacuum generators, then vacuum pressure is improved, but the system becomes expensive
Solution Approach 1:
The ejector apparatus serves as a cost-effective intermediary that can be added to existing electrically driven vacuum generators without requiring expensive modifications to the primary vacuum generator's blower wheels, insulation, or motor components
Solution Approach 2:
The invention merges the function of the primary vacuum generator with the ejector apparatus in a combined system. This integration allows the two devices to work together synergistically, achieving improved vacuum pressure through their combined effect rather than requiring expensive upgrades to a single device
3Stress or pressure
If standard ejectors are used to generate vacuum, then vacuum is created, but energy efficiency is reduced and vacuum level is lower compared to the invention
Solution Approach 1:
The system incorporates feedback mechanisms where the output of the primary vacuum generator is fed into the ejector apparatus, and the combined effect is optimized to achieve higher vacuum levels with better energy efficiency. The flow connection between the primary vacuum generator and ejector allows for optimized energy utilization
Solution Approach 2:
The invention optimizes parameters such as the flow connection configuration, nozzle geometry, and pressure ratios between the primary vacuum generator and ejector apparatus to maximize energy efficiency and vacuum level achievement
4Quantity of substance
If larger flow volumes are evacuated from the lifting tube, then handling capacity is improved, but achieving sufficiently strong vacuum becomes more difficult
Solution Approach 1:
The vacuum generation function is segmented into two stages: the primary vacuum generator handles the bulk flow volume evacuation, while the ejector apparatus provides the final vacuum enhancement. This segmentation allows each component to optimize for its specific function, managing large flow volumes while achieving strong vacuum
Solution Approach 2:
The ejector apparatus acts as an intermediary that bridges the gap between handling large flow volumes and achieving strong vacuum. It takes the output from the primary vacuum generator and enhances it to provide both adequate flow capacity and sufficient vacuum strength for the gripping device
