Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate confinement enclosure is provided around the dust removal column, then dust containment and prevention of ambient spread is improved, but device complexity and difficulty of cleaning/maintenance worsens
Solution Approach 1:
The patent merges the confinement enclosure function with the dust removal column structure itself. The column is designed with a leaktight conveying conduit and integrated aspiration chamber that together contain dust without requiring a separate external enclosure. This integration eliminates the need for additional confinement structures while maintaining dust containment effectiveness.
Solution Approach 2:
The patent extracts the confinement function from a separate enclosure and embeds it within the column structure. The leaktight conveying conduit and aspiration chamber are designed to contain dust internally, removing the need for an external confinement enclosure and simplifying the overall device structure.
2Strength
If the conveying ramp is welded to the central cylindrical element, then structural strength and stability are improved, but manufacturing complexity and assembly difficulty worsen
Solution Approach 1:
The patent segments the column into modular sections that can be assembled without welding. The conveying ramp and central cylindrical element are designed as separate components that connect through mechanical means, allowing for easier manufacturing and assembly while maintaining structural integrity through the modular design.
Solution Approach 2:
The patent replaces the welding process with a mechanical connection system. The conveying ramp is designed to connect to the central cylindrical element through mechanical fastening methods rather than thermal welding, simplifying manufacturing and enabling easier disassembly for maintenance and cleaning.
3Ease of operation
If manual cleaning methods are used, then cleaning capability is provided, but contamination risk and cleaning efficiency worsen
Solution Approach 1:
The patent implements a self-cleaning system where the aspiration chamber and conveying conduit are designed to be cleaned automatically or with minimal manual intervention. The integrated design allows cleaning fluids to flow through the conduits and chambers, enabling self-cleaning operation that reduces contamination risk compared to manual cleaning methods.
Solution Approach 2:
The patent uses hydraulic or pneumatic systems to facilitate cleaning. The aspiration chamber and conveying conduit can be flushed with fluids under pressure, allowing effective cleaning without manual disassembly or contact, thereby reducing contamination risk while maintaining cleaning capability.
4Stability of the object's composition
If the column is designed as a single integrated unit, then structural stability is improved, but ease of assembly and disassembly for cleaning worsens
Solution Approach 1:
The patent segments the integrated column into modular sections that maintain structural stability when assembled but can be easily separated for cleaning. The conveying conduit and aspiration chamber are designed as interconnected modules that form a stable integrated structure during operation but can be disassembled without compromising the structural integrity of individual components.
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
Enhances dust removal capacity, reduces contamination risks, and simplifies the cleaning process by using the existing conduit and chamber for fluid flow, ensuring effective and efficient operation with minimal disruption to production.
Implementation Method 1
the central cylindrical element is depressed thanks to an aspiration means so that the powder dust that covers tablets or capsules is aspirated through said slits into the central cylindrical element and thereby is removed from the device
Implementation Method 2
a motor bloc comprising a motor, for examples an oscillating electromagnetic motor, which when it is switched on, transmits an oscillating movement to the column, which leads tablets or capsules from the bottom to the top of said column
