Dispenser Adapter Translating Tilting Motion to Valve Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dispensers designed to tilt a valve stem are not suitable for cans with Pageris-type valves, which have a stationary valve stem housing, limiting the versatility of dispensers and requiring separate dispensers for different types of valves.
Innovation Solution
An adapter that translates the tilting action of a dispenser into a compressing action to open Pageris-type valves, allowing a single dispenser to function on both tilting and Pageris-type valves by using a base, neck, and bendable segment with a flow channel and plunger to depress the valve stem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dispenser is designed to tilt a valve stem to dispense fluid, then it can function on cans with tilting valve stems, but it cannot be used on cans with Pageris-type valves that require depressing the valve stem
Solution Approach 1:
The patent introduces an adapter as an intermediary component that connects between the dispenser and the can valve. The adapter includes a bendable segment with a plunger that translates the tilting motion of the dispenser into a depressing motion of the valve stem. This intermediary device enables compatibility with both tilting valve stems and Pageris-type valves without modifying the original dispenser structure, thereby resolving the contradiction between versatility and device complexity.
2Adaptability or versatility
If a single dispenser is made compatible with both tilting and Pageris-type valves, then versatility is enhanced, but the device structure becomes more complex
Solution Approach 1:
The patent segments the valve interface into separate components: the dispenser remains simple and unchanged, while the adapter handles the complexity of interfacing with different valve types. The adapter is further segmented into a base portion that attaches to the can, a bendable segment with plunger for motion translation, and a connection interface for the dispenser. This segmentation allows the dispenser to maintain simplicity while the adapter provides the necessary adaptability for different valve types.
3Ease of operation
If the bendable segment is made rigid to maintain structural strength, then it cannot translate tilting motion into linear plunging motion, but if made flexible it loses structural strength
Solution Approach 1:
The patent employs a bendable segment with dynamic characteristics that can flex during operation to translate tilting motion into linear plunging motion of the plunger. The segment is designed with controlled flexibility to bend in a specific manner when the dispenser is tilted, enabling the plunger to move linearly and depress the valve stem. This dynamic design allows the segment to maintain sufficient strength while achieving the required motion translation capability.

Function Achieved in This Case
Enables a single dispenser to be used on both tilting and Pageris-type valves, enhancing versatility and allowing easy one-handed operation, while maintaining fluid communication and secure attachment to the can.
Implementation Method 1
The adapter translates the tilting action of the dispenser to a compressing action required to open a Pageris-type valve
