Elevated Beverage Dispenser Actuator Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial beverage dispensers pose a risk of burns and splashing due to the manual control actuator being located directly above the dispenser valve, which can expose users to hot steam and beverages, and existing shields do not provide a complete solution while also being unsightly.
Innovation Solution
A beverage dispenser design with a manually operable drain valve actuator assembly that is pivotally mounted and protected by guards, allowing for safe operation by keeping the actuator elevated and protected, and a method of assembly and operation that ensures the valve is opened and closed without direct hand exposure to the dispenser valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the manual control actuator is located directly above the dispenser valve, then the device complexity is reduced and operation is simplified, but the user safety deteriorates due to risk of burns from hot steam and beverage splashing
Solution Approach 1:
The actuator is relocated from a vertical position directly above the valve to an elevated position on the front wall, changing the spatial dimension of operation. This dimensional shift moves the user's hand away from the direct path of hot steam and splashing beverage while maintaining operational effectiveness through the linkage mechanism.
Solution Approach 2:
A linkage mechanism serves as an intermediary between the elevated actuator and the valve. The linkage includes a valve member with a plug that blocks the valve opening, and when the actuator is depressed, it moves the plug away from the opening through this intermediary mechanism, allowing valve operation without direct hand exposure to hazards.
2Object-affected harmful factors
If shields are added to protect the user's hand, then the safety improves, but the aesthetic appearance deteriorates and the device complexity increases
Solution Approach 1:
The protective function is extracted from separate shield components and integrated into the actuator assembly itself. The actuator guard is formed as an integral part of the actuator mechanism, providing protection without requiring additional aesthetic-compromising shields. This extraction of the protective function into the operational component eliminates the need for separate protective elements.
3Object-affected harmful factors
If the actuator is elevated and protected by guards, then the user safety and hygiene improve, but the device complexity increases
Solution Approach 1:
Multiple functions are merged into the actuator assembly: the actuator body provides the operational mechanism, the actuator guard provides protection, and the linkage mechanism provides the valve control function. By combining these functions into a single integrated assembly rather than separate components, the overall device complexity is minimized while achieving safety and functionality.
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 solution effectively prevents burns and splashing by maintaining the actuator elevated and protected, enhancing user safety and hygiene while providing an improved aesthetic appearance compared to conventional dispensers.
Implementation Method 1
a movable valve member linked to the drain actuator and having a plug receivable in blocking engagement within the drain hole to close the drain hole
Implementation Method 2
the actuator is pivoted inwardly when in an actuated open position with the actuator being more deeply recessed relative to the actuator guards
Implementation Method 3
a pair of actuator guards located on either side of the actuator to protect the actuator against inadvertent actuation and to provide lateral guidance for relative pivotal movement of the actuator

AI summary
A beverage dispenser has a container for beverage fluid that has a flat bottom that is above a space large enough to place a glass or cup. The container has a sidewall and a top edge of an open container that has a removable lid. A pair of actuator guards are on either side of a space near but below the top edge of the container where an actuator is located that projects through a notch in the top edge, plunging downwardly inside the inner wall of the container sidewall and jutting straight out to form a fork. This fork selectively holds a plunger that has a long shaft and plug that fits into a hole in the bottom wall of the container. This hole and plug form a valve. The valve can be opened when the actuator is depressed between the actuator guards towards the container's sidewall, which pivots the fork upwardly which in turn lifts the plunger and plug to open the valve for dispensation.
