Movable Cap Valve for Air Evacuation and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing caps for containers, such as flasks or bottles, face inefficiencies in transferring fluids from the cap to the container due to air not being effectively expelled during the transfer process, leading to suboptimal mixing in applications like hygiene, cosmetics, and food industries.
Innovation Solution
A cap design with movable parts and an additional element that allows air evacuation from the container while transferring fluid, featuring a conduit with an inlet and outlet, and a valve mechanism to ensure optimal sealing and fluid transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cap seals the container outlet to prevent leakage, then sealing reliability is improved, but air cannot be expelled from the container during fluid transfer
Solution Approach 1:
The cap incorporates a movable additional element that transitions between a first position (allowing air evacuation) and a second position (providing sealing). This dynamic mechanism allows the cap to adapt its sealing state based on the operational phase, enabling both efficient fluid transfer and reliable sealing without compromise.
Solution Approach 2:
The additional element is positioned in the first position before fluid transfer begins, allowing air to be evacuated from the container in advance. This preliminary air removal prevents air entrapment during subsequent fluid transfer, improving transfer efficiency while maintaining sealing capability when needed.
2Productivity
If the additional element remains in the first position for air evacuation, then fluid transfer efficiency is improved, but sealing of the container outlet is compromised
Solution Approach 1:
The additional element dynamically transitions between positions: first position during air evacuation and fluid transfer for optimal productivity, and second position when sealing is required. This dynamic positioning resolves the contradiction by providing the appropriate function at the appropriate time.
Solution Approach 2:
The additional element alternates between air evacuation mode (first position) and sealing mode (second position) based on operational requirements. This periodic switching between functions allows the system to achieve both high fluid transfer efficiency and reliable sealing across different operational phases.
3Reliability
If air is not expelled from the container, then sealing is maintained, but fluid transfer from cap to container is suboptimal
Solution Approach 1:
Air evacuation is performed as a preliminary action before fluid transfer begins. The additional element is positioned in the first position to remove air from the container, creating optimal conditions for subsequent fluid transfer while maintaining the capability to seal when required.
Solution Approach 2:
The system dynamically adjusts the additional element's position to enable air evacuation during fluid transfer operations. This dynamic adjustment allows temporary opening for air removal while maintaining sealing capability, resolving the contradiction between maintaining sealing and optimizing fluid transfer.
