Adjustable-Dosing Pump with Collar-Based Stroke Limiting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pumps and dispensers lack adjustable dosing capabilities and efficient mechanisms for delivering fluid products, particularly in beauty and personal care applications, which limits user experience and product delivery precision.
Innovation Solution
A pump device with a collar having multiple levels or configurations that restrict the pump head's stroke, allowing for adjustable dosing options, and a mechanism for inverted dispensing by actuating a pump when pressed against a surface or user's hand, along with a reservoir filling mechanism using a rotating ring or piston.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple pump structure is used, then device complexity is reduced, but dosing precision and adjustability deteriorate
Solution Approach 1:
The collar is segmented into multiple levels or configurations, each corresponding to a different dosing setting. This segmentation allows the pump to provide adjustable dosing precision without requiring a completely complex pump structure, as the segmentation is localized to the collar component that limits the pump head's stroke.
Solution Approach 2:
The collar is designed to be rotatable or adjustable between different configurations, allowing users to dynamically change dosing settings. This dynamic capability enables the simple pump structure to achieve dosing adjustability and precision through a movable limiting mechanism rather than multiple fixed pump designs.
2Measurement precision
If a collar with multiple dosing configurations is added, then dosing precision is improved, but device complexity increases
Solution Approach 1:
The collar serves multiple functions: it limits the pump head's stroke, provides adjustable dosing configurations, and can be rotated or adjusted by the user. This multi-functionality allows a single component to achieve dosing precision without proportionally increasing overall device complexity, as the collar integrates several features into one element.
Solution Approach 2:
The collar's position or configuration can be changed to alter the dosing parameter (amount of product delivered per stroke). By changing the collar's angular position or configuration state, the system achieves variable dosing precision without requiring multiple different pump structures, thus improving precision while minimizing complexity increase.
3Productivity
If inverted dispensing mechanism is added, then product delivery efficiency is improved, but device complexity increases
Solution Approach 1:
The pump device is designed to function in an inverted position, with the pump head delivering product downward onto a surface or into a user's hand. This inversion allows the pump to utilize gravity to assist product delivery, improving efficiency by reducing the force required to dispense product compared to traditional upward or horizontal dispensing configurations.
Solution Approach 2:
The inverted dispensing mechanism allows the product to be delivered passively under gravity once the pump is actuated, reducing the energy input required for delivery. The system leverages the inverted orientation to enable gravity-assisted flow, improving productivity without requiring additional active components or complex mechanisms.
