Aquarium Filter Scraper Mechanism for Self-Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external filter units for aquariums require cumbersome and time-consuming maintenance to clean the mechanical filter, as the cover needs to be opened and the filter extracted, which increases operator inconvenience and downtime.
Innovation Solution
A filter unit with a scraper mechanism that allows for cleaning of the mechanical filter without opening the external container, featuring a reciprocating slide with scraper blades that detach impurities and an impurity discharge valve for easy removal, along with a comb-like coupling for easy cover attachment, reducing maintenance time and operator inconvenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is opened to access the mechanical filter for cleaning, then the filter can be cleaned, but the maintenance time and operator inconvenience increase
Solution Approach 1:
The mechanical filter cleans itself through an integrated scraper system. The scraper member, positioned on a reciprocating slide, automatically removes impurities from the filter's entrance surface without requiring manual intervention to open the container or extract the filter. This self-cleaning mechanism resolves the contradiction by making the filter maintenance self-service, thereby improving ease of operation while minimizing maintenance time.
Solution Approach 2:
The scraper member acts as an intermediary between the filter and the impurities. Instead of requiring direct human contact with the filter for cleaning, the scraper serves as a mediating element that performs the cleaning function automatically through reciprocating motion, thus improving ease of operation and reducing maintenance time.
2Reliability
If the mechanical filter is extracted for cleaning, then impurities can be removed, but the downtime of the device increases
Solution Approach 1:
The filter maintains its own cleanliness through the automatic scraper system that continuously or periodically removes impurities from the entrance surface. This self-maintenance capability ensures filter efficiency is preserved without requiring the filter to be extracted or the device to shut down for maintenance, thereby resolving the contradiction between reliability and downtime.
Solution Approach 2:
The scraper system operates continuously or periodically to maintain the filter's cleaning function without interruption to the device's operation. This continuous maintenance action ensures the filter remains efficient while the device remains operational, resolving the contradiction between maintaining filter reliability and minimizing downtime.
3Reliability
If multiple peripheral attachments are used to secure the cover, then the container is securely closed, but the cleaning operation becomes more complex
Solution Approach 1:
The scraper system performs the cleaning function independently without requiring the operator to manipulate multiple attachments or open the container. This self-service approach maintains the secure sealing provided by the multiple attachments while eliminating the complexity of manual cleaning procedures, thus resolving the contradiction between reliability and operational complexity.
