Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cartridge filters in spas become clogged quickly, leading to decreased performance and unsanitary conditions due to the inability to effectively remove particles and impurities, and require cumbersome cleaning processes, often resulting in premature replacement.
Innovation Solution
A spa filtration system with a housing and framework that allows for easy replacement and maintenance of filter media and mineral cartridges, utilizing a rectangular slot for filter media and multiple openings for mineral cartridges, connected to the spa shell via a threaded boss for efficient water flow and easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional cartridge filters are used with pleated filter media, then the filter surface area is increased, but the filter becomes clogged more quickly and requires more maintenance
Solution Approach 1:
The filter system is divided into separate functional components: a sediment filter and a carbon filter, each with its own housing and replacement mechanism. This segmentation allows each filter type to be optimized for its specific function and replaced independently, preventing the clogging issues that occur in integrated pleated cartridge filters.
Solution Approach 2:
The filter media is extracted from the traditional pleated cartridge format and replaced with separate sediment and carbon filter elements. The sediment filter uses a simple mesh or screen design that is easily removable and replaceable, while the carbon filter is housed separately, eliminating the clogging problems of pleated cartridges.
2Object-affected harmful factors
If cartridge filters are used to remove particles, then water filtration is achieved, but the filter media becomes clogged with particles lodged between pleats
Solution Approach 1:
The filtration function is segmented into two separate filters: a sediment filter that handles particle removal and a carbon filter that addresses water quality. The sediment filter uses an open mesh design that prevents particle accumulation between pleats, eliminating the clogging problem while maintaining effective particle removal.
Solution Approach 2:
The sediment filter is designed as a disposable element that is easily replaced when clogged, rather than attempting to clean and reuse it. This eliminates the maintenance burden of cleaning pleated cartridges and ensures continuous effective filtration without the harmful clogging effect.
3Object-affected harmful factors
If cartridge filters are used in the circulation system, then water filtration is provided, but the filter requires high pressure reverse flow or vacuum cleaning
Solution Approach 1:
The filtration system is segmented into easily accessible separate housings for the sediment and carbon filters. Each filter can be removed and replaced independently without requiring complex cleaning procedures, high pressure reverse flow, or vacuum techniques, significantly improving ease of operation.
Solution Approach 2:
The filter elements are extracted from the traditional in-line cartridge configuration and placed in separate, easily accessible housings. This extraction allows users to remove and replace filters simply by opening the housing, eliminating the need for complex cleaning operations.
4Productivity
If conventional filtration systems are used, then water circulation is achieved, but particles and impurities remain in the water
Solution Approach 1:
Two different filtration mechanisms are merged into a single system: a sediment filter for physical particle removal and a carbon filter for chemical water quality improvement. This combination achieves both water circulation productivity and water quality enhancement, eliminating the problem of particles and impurities remaining in the water.
Solution Approach 2:
The filtration system uses composite filtration approaches by combining different filter media types (sediment filter and carbon filter) that work together to address both physical particles and chemical impurities, achieving comprehensive water treatment that maintains both circulation efficiency and water quality.
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
The system provides efficient filtration, reduces maintenance effort, and maintains water quality by allowing for regular and simultaneous replacement of filter media and mineral cartridges, thereby extending the filter's lifespan and ensuring sanitary conditions.
Implementation Method 1
Filters are typically mounted in-line within the pool or spa circulation system and have a liquid-permeable filter media such that when the circulation system is in operation, the water can be pulled through the filter and pumped back into the pool or spa, leaving the captured debris on the filter for subsequent removal
