Roll-up Water Bottle Closure Filter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filtration bottles with extended filter systems are not flexible enough to be adapted for different use requirements and cannot be easily rolled up and stored, limiting their versatility and convenience.
Innovation Solution
A roll-up water bottle design featuring a pair of opposed plastic pieces with button-style fasteners and a removable closure/filter assembly, where the filter is secured within the bottle cap, creating water flow channels for even fluid distribution across the filter material, allowing for efficient filtration and easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter system extends throughout the length of the bottle housing, then filtration coverage is improved, but the bottle cannot be rolled up and stored flexibly
Solution Approach 1:
The filter system is segmented from the bottle housing. The filter cartridge is a separate component that can be inserted into and removed from the bottle, allowing the bottle to be rolled up without the filter. The filter is divided into a cartridge body and a separate cap assembly, enabling independent handling and storage.
Solution Approach 2:
The filter cartridge is nested within the bottle housing when installed. The cap assembly with the filter element is inserted into the bottle opening, creating a nested configuration where the filter components are contained within the bottle structure, allowing both to be compact for storage.
2Reliability
If the filter system extends throughout the length of the bottle housing, then filtration effectiveness is improved, but the device complexity increases
Solution Approach 1:
The filter system is divided into distinct modular components: a filter cartridge, a cap assembly with filter element, and a bottle housing. Each component can be manufactured separately and assembled together, reducing overall design complexity while maintaining filtration effectiveness.
Solution Approach 2:
The cap assembly serves multiple functions: it seals the bottle opening, houses the filter element, provides a interface for filter replacement, and structurally supports the filter cartridge. This multi-functionality reduces the number of separate components needed.
3Ease of operation
If the bottle is designed for roll-up storage, then ease of storage is improved, but the filter distribution uniformity deteriorates
Solution Approach 1:
The filter element is positioned at the opening end of the bottle rather than distributed throughout the entire length. This local concentration of filtration material at the opening ensures uniform fluid distribution across the filter surface when the bottle is rolled up, as water enters through the opening and flows evenly across the filter element.
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
Enables a more even distribution of fluid across the filter material, improving filtration efficiency and allowing the bottle to be easily rolled up and stored, enhancing versatility and convenience.
Implementation Method 1
a filter adapted to be removably-retained within a bottle cap of the closure
Implementation Method 2
Upon the user applying suction or pressure from squeezing the bottle, water contained with the bottle flows through vent openings in the filter

AI summary
A roll-up water bottle comprises a hollow cylindrical opening adjacent one end thereof. The opening retains a removable closure/filter assembly. That assembly includes a filter retained within a bottle cap. The cap is positioned within a bottle opening support member retained within the hollow cylindrical opening. The filter housing is generally cylindrical but also includes an outer profile that includes a pair of opposed flat walls. When the filter is secured within the bottle cap and the cap secured within the bottle opening support member, a pair of water flow channels are created. Upon the user applying suction or pressure from squeezing the bottle, water contained with the bottle flows through vent openings in the filter, but also up through the water flow channels. The result is a more even distribution of fluid across a greater portion of the filter.
