Dispensing device for paste products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for paste products, such as toothpaste, require substantial pressure to operate, making it difficult for children to dispense the product effectively, and previous solutions like longer levers are costly to implement due to dimensional changes.
Innovation Solution
A dispensing device with a cylindrical container, a sliding bottom structure for air venting, a flexible diaphragm pumping mechanism, and a button with an extension element that provides increased leverage for easy operation, maintaining the device's size while facilitating product dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a particularly long lever is provided for dispensing the product, then the ease of operation is improved, but the device complexity and manufacturing cost increase due to distorted overall dimensions
Solution Approach 1:
The button is designed to be rotatable about an axis, transitioning between a first position (retracted) and a second position (extended). This dynamic configuration allows the button to provide extended leverage only when needed for dispensing, while maintaining a compact form when not in use. The rotatable mechanism enables the button to extend the lever arm length dynamically without permanently increasing device dimensions.
Solution Approach 2:
The button's rotational movement introduces a new dimensional aspect (angular displacement) to the lever mechanism. By rotating about an axis, the button can extend its effective lever arm length in a rotational dimension without increasing the linear dimensions of the device body, thus avoiding the need for longer overall device length.
2Ease of operation
If a particularly long lever is provided for dispensing the product, then the ease of operation is improved, but the manufacturing cost increases due to new assembly and filling lines
Solution Approach 1:
The dynamic rotational button mechanism allows the device to maintain standard overall dimensions, enabling compatibility with existing assembly and filling production lines. The button rotates into place during assembly rather than requiring custom positioning, and the compact retracted state allows standard filling operations without modification.
Solution Approach 2:
The rotatable button design maintains compatibility with standard device dimensions and assembly procedures while adding the multi-functionality of extended leverage when needed. This universal approach allows the same production infrastructure to handle both standard and enhanced-dispersion devices without requiring separate specialized lines.
3Ease of operation
If a particularly long lever is provided for dispensing the product, then the ease of operation is improved, but the device dimensions are distorted
Solution Approach 1:
The button rotates about an axis to extend the lever arm length dynamically during the dispensing action. When retracted to the first position, the button maintains a compact profile that preserves standard device dimensions. During dispensing, it rotates to the second position to provide the extended lever arm for easier operation, thus achieving long leverage without permanently distorting device length.
Solution Approach 2:
The button's rotational mechanism allows the extended lever arm to be 'nested' within the compact device body when not in use. The button can be positioned within the device housing in the retracted state, and only extends outward when rotated into the dispensing position, effectively nesting the extended lever function within the standard device footprint.
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 allows for easy and efficient dispensing of paste products without significant size changes, making it accessible for children and reducing costs associated with new assembly and transport systems.
Implementation Method 1
When the proper pressure is exerted on the button, it undergoes a rotation, frees a dispensing mouth and causes the release of a predefined quantity of product
Implementation Method 2
a flexible diaphragm pumping mechanism
Implementation Method 3
The bottom structure slides sealingly towards the upper end of the container, without the ability to return, and provides for venting means for the escape of air trapped between the paste product and the structure itself during the operations of filling the container

AI summary
A dispensing device for paste products, including toothpaste, is provided. The dispensing device includes a container, a pumping diaphragm and a head applied to the container. The head is equipped with a tube and a button for acting on the diaphragm and deforming it for dispensing. The button has a pressure surface for a user's dispensing action. An extension element which, in an active position, is arranged as an extension of the pressure surface of the button, increases a leverage effect.
