Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household water filtration devices, such as table water filters and kettle-based systems, are bulky and unwieldy due to their design, making them difficult to store and handle, and offer limited design flexibility.
Innovation Solution
A gravity-operated water filtration device comprising a stationary base station with a removable water collection container that can be designed as a jug, carafe, or kettle, allowing for compact storage and easy handling, with a filter cartridge for treating water that can be replaced regularly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional table water filter with a funnel and water collection chamber is used, then water filtration function is achieved, but the device becomes bulky and difficult to store in the refrigerator
Solution Approach 1:
The device is divided into two separate functional components: a stationary base station containing the funnel and filter cartridge, and a removable water collection container. This segmentation allows the bulk of the device (base station) to remain fixed in one location while only the water collection container needs to be stored in the refrigerator, significantly reducing storage space requirements while maintaining filtration functionality.
Solution Approach 2:
The water collection container is extracted as a separate removable component from the traditional integrated funnel design. By taking out the water collection function from the filtration structure, the patent enables the base station to remain stationary and compact, while the collection container can be independently stored in the refrigerator when not in use.
2Reliability
If a kettle with a filter cartridge inserted into a spout is used, then water purification is achieved, but the handling of the spout becomes cumbersome and the kettle must be separated for convenient use
Solution Approach 1:
The system is segmented into a stationary base station with the filter cartridge and a separate removable water collection container. This allows the filtration system to remain fixed and reliable while the collection container can be easily removed and handled independently, eliminating the cumbersome spout handling issue of traditional kettle filters.
Solution Approach 2:
The water collection container is designed to be self-contained and removable, allowing users to easily take it away for filling or emptying without needing to disassemble or manipulate complex spout mechanisms. The container serves itself by being directly placeable on the base station for filling.
3Quantity of substance
If a table water filter with a large funnel volume is used, then sufficient filtration capacity is achieved, but the overall device design flexibility is limited
Solution Approach 1:
By separating the filtration system (base station with funnel) from the water collection container, the patent enables independent optimization of each component. The base station maintains sufficient filtration capacity with an appropriately sized funnel, while the collection container can be designed in various shapes, sizes, and styles, greatly enhancing design flexibility and adaptability.
Solution Approach 2:
The removable water collection container can serve multiple functions: collecting filtered water, serving as a storage container in the refrigerator, and potentially being used for other purposes when detached from the base station. This universality increases design flexibility while maintaining adequate filtration capacity in the base station.
