Adjustable Fluid Dispenser Dosing With Reversible Pump Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispensers lack the ability to adjust the dosage of dispensed fluid according to specific requirements, which can vary by environment and application, leading to inefficiencies and potential misuse.
Innovation Solution
A fluid dispenser with an adjustable dosing mechanism that allows for high and low dose settings, achieved through a horseshoe-shaped body with dose adjusting flanges and a pump system that changes the gap size between the actuator and pump engagement surfaces, enabling variable fluid quantities to be dispensed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed dosing mechanism is used in fluid dispensers, then the device structure is simple, but the adaptability to different dosage requirements is poor
Solution Approach 1:
The patent applies the dynamics principle by making the dosing mechanism adjustable rather than fixed. The pump assembly can be repositioned along the pushbar to change the actuation distance, allowing the same dispenser to provide different dosage levels (high dose, low dose, or custom doses) based on user needs, thereby improving adaptability without requiring multiple different dispenser models
Solution Approach 2:
The patent implements parameter changes by modifying the actuation distance parameter between the pushbar and pump engagement surface. By adjusting this distance parameter, the system changes the pump depression depth and consequently the fluid dosage dispensed, enabling flexible dosage control while maintaining the same basic device structure
2Ease of operation
If manual adjustment of dosing is required, then manufacturing precision is reduced, but ease of operation is improved
Solution Approach 1:
The patent applies preliminary action by pre-configuring the pump assembly with engagement features that align with marked positions on the pushbar. The high dose and low dose positions are pre-marked during manufacturing, allowing users to easily install the pump at the correct position without requiring complex adjustment mechanisms or sacrificing dosing precision
Solution Approach 2:
The patent implements self-service by enabling users to easily adjust the dosing level themselves during installation or maintenance. The pump assembly can be independently positioned and secured at different dosing levels without requiring specialized tools or technical expertise, placing the adjustment capability directly in the user's hands

AI summary
A fluid dispenser includes an adjustable dosing mechanism that permits adjustment of the amount of fluid to be dispensed. An adjustable dosing mechanism may be inserted into the dispenser in either a high dose orientation or a low dose orientation. The body further includes pair of dose adjusting flanges. When the adjustable dosing mechanism body is received into the dispenser in the high dose orientation, a relatively larger quantity of fluid product is dispensed. When the adjustable dosing mechanism body is received into the dispenser in the low dose orientation, a relatively smaller quantity of fluid product is dispensed.
