Bottom-fill Hydration Bottle Deflector and Diffuser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydration bottles used for bottom-fill systems often suffer from contamination and fluid wastage due to vertical nozzle orientation, which causes fluid to shoot out of the top opening, leading to a messy and inefficient hydration process during outdoor sporting events.
Innovation Solution
A bottom-fill hydration bottle design featuring a valve assembly with a deflector and diffuser to redirect fluid flow horizontally, preventing vertical discharge and minimizing spills, while maintaining a cap with a central spout for easy drinking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vertical nozzle is used to force water upward at speed, then filling speed is improved, but fluid escapes out of the top opening causing wastage and mess
Solution Approach 1:
The deflector redirects the fluid flow from a vertical path to a horizontal path, changing the dimension of fluid discharge. This allows the nozzle to maintain vertical orientation for high-speed filling while the deflector directs fluid horizontally into the bottle, preventing escape through the top opening.
2Ease of operation
If the top of the bottle has an opening for air escape during bottom-filling, then air venting is improved, but fluid can escape through the same opening
Solution Approach 1:
The opening in the bottle top is segmented into two separate functions: one portion allows air to escape during filling, while another portion (or the same portion at different times) allows the deflector to redirect fluid horizontally. This segmentation enables both air venting and fluid containment to coexist.
3Device complexity
If traditional top-filling is used, then filling process is simple, but contamination from dirt, grass and debris is transferred into the beverage
Solution Approach 1:
The filling process is inverted from traditional top-filling to bottom-filling. Instead of pouring fluid from the top where contaminants can fall in, the bottle is filled from the bottom through a valve assembly with a deflector, reversing the filling direction to eliminate contamination risks.
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 solution effectively prevents fluid from escaping through the top opening, reducing contamination and wastage, ensuring athletes receive a clean and full hydration bottle during events.
Implementation Method 1
a deflector positioned along the valve assembly within the main body of the bottle. The deflector including an input opening and at least one aperture that functions to discharge the received fluid in a direction that is different than the outlet opening of the valve
Implementation Method 2
a diffuser positioned along the bottom opening of the spout. The diffuser including an output opening and at least one aperture that functions to receive fluid from the main body at an angle that is different from the bottom end of the spout
