Integrated Canteen with Pump and Filter for On-Demand Water Purification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canteens do not provide a solution for carrying unfiltered water and filtering it away from the initial water source, lacking a integrated filter and pumping mechanism for on-demand filtration.
Innovation Solution
A canteen design incorporating a reservoir for unfiltered water, a built-in filter for impurity removal, and a pump mechanism to dispense filtered water through a spout, allowing for on-demand filtration away from the water source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a canteen carries unfiltered water for later filtration, then water carrying capability is improved, but filtration and pumping functionality is lacking
Solution Approach 1:
The patent combines the reservoir, filter, and pump into a single integrated canteen unit. The filter is positioned within the reservoir body, and the pump is integrated into the spout assembly, creating a unified system that carries unfiltered water and provides on-demand filtration without requiring separate components.
Solution Approach 2:
The canteen serves multiple functions: it stores unfiltered water in the reservoir, filters water through the built-in filter element, pumps water through the hand-operated pump mechanism, and dispenses filtered water through the spout. This multi-functional design eliminates the need for separate filtration and pumping devices.
2Reliability
If a built-in filter is added to the canteen, then water purification is improved, but device complexity increases
Solution Approach 1:
The filter is integrated directly into the reservoir structure, with the filter element positioned within the reservoir body. This merging of the filter with the reservoir eliminates the need for separate filtration devices and reduces overall system complexity while maintaining purification functionality.
3Ease of operation
If a pump mechanism is added for on-demand filtration, then water dispensing capability is improved, but device complexity increases
Solution Approach 1:
The pump is integrated into the spout assembly, combining the pumping function with the water dispensing structure. This integration allows the pump to be operated directly as part of the spout mechanism, simplifying the overall device while maintaining on-demand water dispensing capability.
Solution Approach 2:
The hand-operated pump mechanism allows users to actively pump water from the reservoir through the filter and out the spout. This self-service pumping capability enables on-demand water dispensing without requiring external power sources or complex automated systems.
4Adaptability or versatility
If the filter and pump are integrated into the canteen, then portability is improved, but manufacturing complexity increases
Solution Approach 1:
The canteen is divided into distinct functional segments: the reservoir body containing the filter, the spout assembly containing the pump, and the connection passages between them. This segmentation allows each component to be manufactured separately and then assembled, reducing overall manufacturing complexity while maintaining portability.
