Movable Outlet Valve with Bypass Passage for Fluid Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for fluids and liquid mixtures face challenges in estimating the filled amount, ensuring mixing quality, and preventing backflow during filling, which is crucial for applications like hair treatment lotions where different concentrations can lead to uneven color shades.
Innovation Solution
A container design featuring a receiving vessel with a one-way valve and bypass passage that allows for controlled filling and emptying, preventing backflow and ensuring accurate measurement and mixing, facilitated by a movable outlet part that seals and unseals the bypass passage, and a design that allows for easy closing without additional sealing members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a one-way valve is added to prevent backflow during filling, then filling reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines the one-way valve function with the movable outlet part mechanism. The outlet part serves dual purposes: controlling the bypass passage and preventing backflow through the one-way valve design, thereby reducing the need for separate components and minimizing device complexity while maintaining filling reliability
2Ease of operation
If a movable outlet part with bypass passage is used to control filling, then filling control is improved, but emptying operation becomes more complex
Solution Approach 1:
The outlet part is designed to be movable between different positions (first position for filling with bypass open, second position for emptying with bypass closed). This dynamic reconfiguration allows the same component to serve multiple functions: controlling filling through the bypass passage while automatically preventing backflow during emptying, thus improving filling control without permanently complicating emptying operations
3Reliability
If additional closing means are added to seal the bypass passage, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The system utilizes the movable outlet part itself to perform the sealing function. When the outlet part moves to the second position during emptying, its structure automatically closes the bypass passage without requiring additional sealing members. The outlet part serves its own sealing need, eliminating the requirement for separate closing mechanisms and maintaining device simplicity while ensuring sealing reliability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design facilitates filling without complicating emptying, ensures accurate measurement and improved mixing quality by preventing backflow and residual component washout, and maintains consistent concentrations in hair treatment lotions, ensuring uniform color shades.
Implementation Method 1
the outlet part comprises a one-way valve and at least one bypass passage bypassing the one-way valve
Implementation Method 2
in the closed position the receiving vessel seals the bypass passage and in the opened position the receiving vessels unseals the bypass passage

AI summary
A container is provided comprising a receiving vessel (12) and an outlet part (14), wherein the outlet part (14) comprises a one-way valve (24) and at least one bypass passage (32) bypassing the one-way valve (24), wherein the outlet part (14) is at least partly movable with respect to the receiving vessel (12) between a closed position and an opened position, wherein in the closed position the receiving vessel (12) seals the bypass passage (32) and in the opened position the receiving vessels (12) unseals the bypass passage (32). Due to the one-way valve (24) of the alternative container (10) the filling is facilitated without complicating emptying, since it is prevented that the content (42) of the container (10) flows back accidently.
