Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for filtering plastic melt require frequent and time-consuming filter lattice replacements, leading to high personnel input and limited installation space due to their large size, which disrupts continuous filtration, especially in heavily contaminated scenarios.
Innovation Solution
A device with a filter canister containing multiple filter cartridges anchored to a substrate, allowing for easy replacement by flushing with gas and using a removable cover, increasing filter surface area and reducing replacement intervals, while maintaining compactness and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple filter cartridges are arranged in separate filter canisters, then filter lattice replacement can be performed alternately to maintain continuous filtration, but the device requires large installation space and frequent personnel intervention
Solution Approach 1:
Multiple filter cartridges are merged into a single filter canister, allowing them to share common structural components and support structures. This consolidation reduces the overall installation space while enabling simultaneous operation of multiple filters, maintaining continuous filtration capability without requiring separate canisters for each filter cartridge.
Solution Approach 2:
The filter canister is designed with a removable cover that allows individual filter cartridges to be accessed and replaced independently. This segmentation enables maintenance of one filter cartridge without affecting others, ensuring continuous filtration operation while reducing the need for large installation space compared to completely separate canisters.
2Area of stationary object
If filter cartridges are arranged in a compact configuration, then installation space is reduced, but filter lattice replacement becomes more difficult and time-consuming
Solution Approach 1:
The filter canister incorporates a removable cover that transforms the static enclosed structure into a dynamic accessible system. This allows the filter cartridges to be easily accessed and maintained without permanent disassembly, making filter lattice replacement simple and quick despite the compact arrangement of multiple cartridges within the canister.
3Duration of action of stationary object
If filter surface area is increased to extend replacement intervals, then device size increases, but frequent replacement intervals require high personnel input
Solution Approach 1:
The total filter surface area is segmented into multiple individual filter cartridges within a single canister. This allows the system to achieve a large cumulative filter surface area for extended operation intervals while maintaining a compact overall device size through shared structural components. Multiple cartridges can be replaced in parallel or sequentially without requiring a single oversized filter unit.
