Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable water filtration devices are bulky and impractical for everyday use outside the home, making it difficult for consumers to access filtered water away from home.
Innovation Solution
A portable drinking container with a main reservoir, a filling reservoir connected by a filter, and a plunger assembly that allows liquid to be added and filtered through a porous filter into the main reservoir, enabling efficient filtration and transport of filtered water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If portable filtration devices are designed for camping use, then filtration capability is provided, but the devices become bulky and impractical to transport
Solution Approach 1:
The device is divided into separate functional modules: a collapsible filtration chamber, a removable filter element, and a reservoir. This segmentation allows each component to be optimized independently and enables compact storage when not in use, resolving the contradiction between providing filtration capability and maintaining portability.
Solution Approach 2:
The filter element is designed to nest within the filtration chamber, and the reservoir can be collapsed or nested within the filtration chamber when empty. This nesting arrangement minimizes the overall device volume while maintaining full filtration functionality when deployed.
2Productivity
If a plunger assembly is used to urge liquid through the filter, then filtration efficiency is improved, but device complexity increases
Solution Approach 1:
The plunger assembly is designed to be manually operated by the user without requiring external power sources or complex control mechanisms. The user simply pushes the plunger to urge liquid through the filter, making the system self-sufficient and easy to operate while maintaining high filtration efficiency.
Solution Approach 2:
The patent replaces complex mechanical filtration systems with a simple manual plunger mechanism that uses direct mechanical force to push liquid through the filter element. This substitution reduces device complexity while maintaining filtration effectiveness.
3Reliability
If a porous filter is used between reservoirs, then water purification is achieved, but the filter requires frequent replacement
Solution Approach 1:
The filter element is designed to be easily removable and replaceable. When the filter becomes saturated or damaged, users can discard it and install a fresh filter element. This approach ensures continuous water purification while accommodating the limited service life of porous filters through convenient replacement rather than complex regeneration systems.

AI summary
A drinking container includes a main reservoir; a filling reservoir; a filter connecting the filling reservoir to the main reservoir; a plunger assembly having a plunger head sized complementary to the interior of the filling reservoir and a shaft extending therefrom to allow the plunger head to be urged into the filling reservoir, thereby urging liquid in the filling reservoir through the porous filter into the drinking reservoir. The shaft may define a passageway from an opening in the plunger head, to allow addition of liquid through the passageway into the filling reservoir. A valve allows closing of the opening to allow the plunger head to be urged into the filling reservoir, thereby urging liquid in the filling reservoir through the filter into the drinking reservoir.
