Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter-drying methods, such as using drying cabinets or autoclaves, are time-consuming and can expose filters to thermal stress, potentially damaging them, or fail to guarantee complete drying.
Innovation Solution
A filter-drying device that uses compressed air to dry filters quickly and completely, without subjecting them to thermal stress, by fluidically connecting the compressed-air connector to the filter connector in a first functional state and separating them in a second functional state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filters are dried in a drying cabinet, then drying is achieved, but drying is very time-consuming (longer than eight hours) and filters are exposed to thermal stress causing damage
Solution Approach 1:
The patent replaces the thermal drying system (drying cabinet using heat) with a pneumatic drying system using compressed air. The compressed air is directed through the filter via a filter-drying device, eliminating thermal stress while achieving complete drying. This substitution resolves the contradiction by removing the harmful thermal effect while maintaining drying effectiveness and reducing time.
Solution Approach 2:
The invention uses compressed air (pneumatics) to dry the filter from the inside. The filter-drying device connects a compressed air source to the filter, allowing pressurized air to flow through the filter and evaporate remaining moisture. This pneumatic approach eliminates the need for prolonged thermal exposure while ensuring complete drying, thus reducing drying time without compromising filter integrity.
2Reliability
If filters are dried by means of an autoclave, then drying is achieved, but drying is very time-consuming and complete drying cannot be guaranteed
Solution Approach 1:
The filter-drying device uses compressed air delivered through a connector system to dry the filter from the inside. The pneumatic system allows pressurized air to penetrate deep into the filter structure, ensuring complete drying of all internal surfaces and channels. This approach guarantees drying completeness while significantly reducing the time required compared to autoclave methods.
Solution Approach 2:
The invention changes the drying parameters by using pressurized gas flow instead of thermal or vacuum conditions. By controlling the pressure and flow rate of compressed air, the system achieves rapid and complete drying. The parameter change from thermal/vacuum to pneumatic drying enables both time reduction and guaranteed drying completeness.
3Productivity
If thermal stress is applied to dry filters, then drying is achieved, but the filter can be irreparably damaged
Solution Approach 1:
The patent substitutes the thermal field (heat) with a pneumatic field (compressed air) for the drying process. The filter-drying device delivers compressed air through the filter, using gas flow and pressure to remove moisture without thermal exposure. This substitution eliminates the harmful thermal effect while maintaining high drying efficiency through the kinetic energy of the pressurized air stream.
