Solution Overview

Problem

Existing dispensing devices lack versatility and user-friendliness in actuating valves, as they often require manual action and do not efficiently utilize the profile of the container for actuation.

Innovation Solution

A valve design featuring a rocker that can be actuated at either end or between ends, allowing fluid flow from a valve inlet to an outlet, with a valve pin biased by a spring, enabling convenient and flexible actuation by manual or container-based action.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a manual lever actuation mechanism is used, then the valve can be actuated by user action, but it lacks versatility and cannot be actuated by container action

Engineering Contradiction:
Improveactuation versatilityVSAvoidactuation mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rocker is designed with a multi-functional actuation capability, allowing it to be actuated by either manual lever action or by the profile of a container being pushed against it. This universal design enables the same component to serve multiple actuation purposes without requiring separate mechanisms for each method.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The rocker mechanism is designed to be dynamically responsive to different actuation forces and directions. It can pivot and respond to forces applied at various locations along its length, allowing adaptive response to both manual operation and container-based actuation without requiring a fixed, rigid actuation path.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a fixed actuation point on the valve is used, then the valve mechanism is simple, but it requires precise manual action and is not user-friendly

Engineering Contradiction:
Improveactuation easeVSAvoidrocker mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The rocker is segmented into multiple functional zones along its length, with different sections capable of receiving actuation forces. This segmentation allows users to actuate the valve by applying force at various convenient locations rather than requiring precise action at a single fixed point, thereby improving ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rocker serves as an intermediary element between the user/container and the valve pin. It translates and transmits actuation forces from various locations and directions into the appropriate motion to actuate the valve pin, thereby decoupling the complexity of force transmission from the user interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a single-direction actuation switch is used, then the actuation mechanism is simple, but it cannot accommodate both manual and container-based actuation

Engineering Contradiction:
Improveactuation method adaptabilityVSAvoidoperation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The rocker is designed as a universal actuation interface that can accommodate multiple actuation methods (manual lever action and container profile pushing) through its ability to respond to forces applied at various locations along its length, eliminating the need for separate actuation mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The actuation capability is extended from a single-point, single-direction interface to a multi-point, multi-directional interface. The rocker's elongated structure allows actuation forces to be applied along its length, adding a spatial dimension to the actuation interface and enabling versatile operation methods.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
