Liquid Dispensing Device Sealing Component Immobilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensing devices fail to provide effective sealing of the dispensing nozzle during storage and transport, leading to potential liquid leakage and contamination risks.
Innovation Solution
A liquid dispensing device equipped with a sealing component that can switch between release and blocking positions, featuring a flexible elastomer or thermoplastic material, and immobilization means to prevent accidental movement, ensuring secure sealing through compression and deformation, and a cap that activates immobilization when fitted, preventing liquid escape and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a movable sealing component is used to allow liquid dispensing, then liquid release functionality is improved, but sealing reliability during storage deteriorates due to accidental movement
Solution Approach 1:
The patent applies preliminary action by providing immobilization means that are activated before use (during storage and transport) to prevent the sealing component from moving accidentally. The cap, when fitted, engages with the sealing component to lock it in the blocking position, ensuring reliable sealing before the device is actually used for dispensing liquid.
2Reliability
If immobilization means are added to prevent accidental sealing component movement, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the immobilization function with the existing cap structure. The cap is designed to engage with the sealing component and lock it in place, combining the protective covering function with the immobilization function in a single integrated component, thereby minimizing additional complexity.
Solution Approach 2:
The immobilization means are designed to be automatically activated when the cap is fitted on the device. The cap itself performs the immobilization action through its engagement with the sealing component, eliminating the need for separate complex locking mechanisms or additional actuation systems.
3Ease of operation
If the sealing component is left movable during storage, then ease of operation is maintained, but liquid contamination risk increases due to accidental liquid flow
Solution Approach 1:
The patent applies preliminary action by ensuring the sealing component is locked in the blocking position before the device is used, during storage and transport. This preliminary immobilization prevents any accidental liquid flow that could lead to contamination of surfaces or environments outside the sealed area.
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 device provides reliable sealing and prevents liquid contamination by immobilizing the sealing component, ensuring the liquid remains within the sealed area during storage and transport, maintaining the liquid's integrity and preventing accidental release.
Implementation Method 1
switch from the liquid release position to the liquid blocking or non-return position by moving the component and/or by elastic deformation of all or part of the component
Implementation Method 2
The immobilisation means exert a pressure on the sealing component, so as to prevent it from moving to its liquid release position
