Innovation Solution
A sucking device with first and second sucking means connected via switching means, allowing operation in parallel or series configurations to vary air flow rate and vacuum, enabling adaptation to different conditions by switching between modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple sucking elements connected in parallel are used, then air flow rate is improved, but vacuum generation deteriorates
Solution Approach 1:
The patent applies dynamics by making the connection configuration between sucking elements changeable rather than fixed. The switching means enables the system to dynamically reconfigure between parallel connection (for high air flow rate) and series connection (for high vacuum) based on operational requirements, resolving the contradiction between these two performance parameters.
2Stress or pressure
If powerful motors are installed in multistage sucking elements, then vacuum is improved, but device complexity and cost worsen
Solution Approach 1:
The system uses dynamic reconfiguration of the sucking elements through switching means. Instead of requiring continuously powerful motors, the system achieves high vacuum by switching to series connection where the same motors operate in a configuration that multiplies their vacuum-generating effect, thereby reducing motor power requirements and overall device complexity.
Solution Approach 2:
The sucking elements are designed to be multi-functional, serving dual purposes: they can operate in parallel for high air flow rate applications and in series for high vacuum applications. This universality eliminates the need for separate specialized components or overly powerful motors, simplifying the overall device design.
3Stress or pressure
If sucking elements are connected in series, then vacuum is improved, but air flow rate deteriorates
Solution Approach 1:
The switching means enables dynamic reconfiguration between series and parallel connections. When high vacuum is required, the system switches to series connection accepting reduced air flow rate. When high air flow rate is needed, it switches to parallel connection. This dynamic adaptability resolves the contradiction by allowing the system to optimize for whichever parameter is currently most important.
