Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid storage and release devices face issues with liquid volatilization, drainage, and uncontrolled release, making them unsuitable for complex mixing operations or slow release applications, and they often pose safety hazards due to glass ampoule breakage.
Innovation Solution
A liquid storage and release device comprising a tube shell, a capsule-like liquid container, and a piston rod with a piercing component, where the piston rod slides to apply pressure and pierce the container for controlled liquid release, using a hollow tube structure with a liquid channel and optional rotation constraint and liquid absorbing material for slow and controlled release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional liquid storage structures are used, then liquid can be stored, but liquid will be volatilized and drain during storage
Solution Approach 1:
The liquid storage system is segmented into separate components: a capsule-like liquid container for storing liquid, a piercing component for controlled release, and a piston rod for actuation. This segmentation prevents liquid drainage and volatilization by keeping the liquid sealed in the capsule until release is needed.
Solution Approach 2:
The piercing component is pre-positioned within the tube cavity, ready to pierce the capsule-like liquid container when the piston rod is pushed. This preliminary positioning enables immediate controlled release when needed, while maintaining liquid stability during storage.
2Adaptability or versatility
If liquid mixing operation is required, then complex mixing can be achieved, but liquid release becomes uncontrolled and pressure builds up
Solution Approach 1:
The device employs dynamic control through the piston rod, which can be pushed to different extents to control the piercing action and liquid release rate. The piercing component can dynamically pierce the capsule to enable mixing while the piston rod provides continuous control over the release process.
Solution Approach 2:
The piston rod acts as an intermediary between the user and the liquid release mechanism. By pushing the piston rod, the user indirectly controls the piercing component's action on the capsule, enabling precise control over liquid release and mixing operations.
3Reliability
If glass ampoules are used to store liquids, then liquid can be sealed, but safety hazards arise from glass fragments after breakage
Solution Approach 1:
The capsule-like liquid container replaces traditional glass ampoules with a disposable capsule structure that can be safely pierced without generating hazardous fragments. The capsule is designed for single-use piercing and release, eliminating the safety risks associated with glass breakage while maintaining effective liquid sealing.
4Productivity
If liquid release is accelerated, then output speed increases, but mixing effectiveness decreases
Solution Approach 1:
The piercing component and piston rod create a dynamic release system where the piercing action can be controlled to match the desired output speed. By adjusting the piercing depth and speed through piston rod movement, the system maintains optimal mixing conditions while achieving the required liquid output rate.
