Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable sock filters for saltwater fish tanks are messy, inefficient, introduce harmful chemicals, and require frequent replacement, leading to reduced filtration efficiency.
Innovation Solution
A filter assembly comprising a sleeve, spine, and stacked discs with diagonal grooves that trap debris while allowing clean water flow, sealed with an O-ring and featuring a vented lid and media cup for efficient filtration without the need for frequent cleaning or replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sock filters are used for water filtration, then debris can be captured, but the filters clog and require frequent cleaning or replacement
Solution Approach 1:
The filter is divided into multiple functional layers: a permanent outer mesh sock for capturing large debris, and multiple disposable inner filter discs with varying pore sizes for capturing finer particles. This segmentation allows the permanent sock to be easily removed and cleaned of large debris, while the inner discs can be independently replaced, reducing overall maintenance time and improving filtration reliability.
Solution Approach 2:
The invention uses disposable inner filter discs that can be discarded after use, eliminating the need to clean and reuse degraded filter media. The permanent outer sock is recovered and reused after simple cleaning, maximizing resource utilization while maintaining filtration effectiveness.
2Productivity
If sock filters are cleaned repeatedly, then they can continue to be used, but the material loses thickness and effectiveness
Solution Approach 1:
The inner filter discs are designed as disposable components that are discarded after a set number of uses or when clogged, preventing the material degradation that occurs with repeated cleaning. The permanent outer sock is recovered and reused, extending overall filter lifespan while maintaining reliability through the replacement of degraded inner discs.
Solution Approach 2:
The filter assembly combines a permanent reusable outer mesh structure with disposable inner filter discs made of different materials optimized for specific filtration functions. This composite approach allows each component to be optimized for its specific role, with the disposable discs absorbing the wear from repeated use.
3Ease of operation
If sock filters are laundered, then debris is removed, but residual detergents and phosphates are introduced into the tank
Solution Approach 1:
The inner filter discs are designed to be disposed of after use rather than laundered, completely eliminating the introduction of detergents and phosphates into the tank. The outer permanent sock can be rinsed with fresh water to remove debris without requiring chemical detergents, thus avoiding chemical contamination while maintaining ease of operation.
4Reliability
If sock filters are used, then filtration is provided, but the socks collapse and reduce effective filtration surface area
Solution Approach 1:
The filter is segmented into a rigid support structure (outer mesh sock with rigid rim) and flexible filter media (inner discs). This segmentation provides structural integrity to maintain the filtration surface area while allowing the filter media to perform its function. The rigid rim prevents collapse, and the segmented design allows water to flow through multiple pathways.
Solution Approach 2:
The filter assembly uses composite materials combining rigid structural components (plastic rim, mesh sock) with flexible filter media (inner discs). This composite structure provides the necessary strength to maintain filtration surface area while enabling effective filtration. The rigid outer structure prevents collapse, and the inner discs provide the filtration function.
