Compressible device for drinking container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drinking containers lack an automatic spill-proof mechanism, leading to liquid spillage when tipped over, as users must manually operate the suction tube to prevent leakage.
Innovation Solution
A compressible device with a base and spill-proof units featuring a through slot and a deformable spill-proof seat, where the plate body with slits opens to allow liquid flow when compressed, but is closed by liquid pressure when the container is tipped, providing an automatic spill-proof effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suction tube is left in the unbent state for easy access, then the user can conveniently drink liquid, but the liquid will flow out through the suction tube when the container is tipped over
Solution Approach 1:
The spill-proof seat automatically responds to liquid pressure and tilting forces without requiring user intervention. When the container is tipped, liquid pressure closes the slit in the plate body, automatically preventing spills without the user needing to remember to bend the suction tube
Solution Approach 2:
The plate body and spill-proof seat are designed to dynamically respond to changing conditions. The slit in the plate body can open when compressed by the user for drinking, and close when liquid pressure acts on it during tilting, providing adaptive spill protection based on real-time forces
2Reliability
If a manual bend mechanism is added to the suction tube to prevent spills, then spill-proof performance improves, but the device complexity increases and requires user operation
Solution Approach 1:
The spill-proof seat includes a plate body with a slit that acts as a flexible barrier. This thin flexible structure selectively blocks or allows liquid flow based on compression and pressure conditions, providing spill protection without complex mechanical components
Solution Approach 2:
The system changes the state of the slit from open to closed based on physical parameters (compression force and liquid pressure). When liquid pressure increases during tilting, the slit closes automatically, providing spill protection through parameter-based state change rather than complex mechanics
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
Ensures liquid containment without user intervention, preventing spills when the container is tilted by automatically sealing the flow passage under liquid pressure.
Implementation Method 1
When the plate body is compressed and deformed, the first slit is opened to communicate the liquid inlet zone with the liquid outlet zone through the through slot
Implementation Method 2
the first slit is opened to communicate the liquid inlet zone with the liquid outlet zone through the through slot... ensuring the slits remain closed under liquid pressure

AI summary
A compressible device for use on a drinking container includes a base and at least one spill-proof unit. The base includes a base wall defining a liquid flow passage, and a separation wall connected to the base wall and dividing the liquid flow passage into a liquid inlet zone and a liquid outlet zone. The at least one spill-proof unit includes a through slot formed in the separation wall and communicating with the liquid outlet zone, and a spill-proof seat including a plate body opposite to the through slot and formed with a first slit. When the plate body is compressed and deformed, the first slit is opened to communicate the liquid inlet zone with the liquid outlet zone through the through slot.
