Water Dispenser Push Bar Hinge for Actuation and Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push bars in water dispensers require varying amounts of force and movement distance for actuation, are difficult to service, and lack favorable aesthetic and ergonomic design.
Innovation Solution
A push bar mechanism with a hinge mechanism that allows pivoting between rest, activation, and service positions, featuring a reinforcing piece for increased strength and rigidity, and hinge arms for uniform actuation, enabling consistent force transmission and easy access to internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional push bar is used in water dispensers, then the actuation mechanism is simple, but the force required for actuation varies depending on the point along the longitudinal length
Solution Approach 1:
The push bar is divided into two distinct segments: a face piece for user engagement and a reinforcing piece for structural support. This segmentation allows each part to be optimized for its specific function, ensuring uniform actuation force while maintaining structural integrity.
Solution Approach 2:
The push bar combines two different pieces (face piece and reinforcing piece) into a composite structure. The face piece provides the user interface while the reinforcing piece provides structural strength, creating a composite component that achieves both operational consistency and structural rigidity.
2Ease of repair
If a fixed push bar is used, then the structure is stable, but the push bar is difficult to service
Solution Approach 1:
The push bar is designed to be movable rather than fixed, pivoting on a hinge mechanism. This dynamic design allows the push bar to be moved to a service position for maintenance while returning to a stable operational position during normal use, achieving both serviceability and structural stability.
Solution Approach 2:
The push bar serves multiple functions: it acts as the normal operational actuator during water dispensing and as an access door during servicing. This multi-functionality is achieved through its ability to pivot between operational and service positions.
3Ease of manufacture
If a simple push bar design is used, then the manufacturing is easy, but the aesthetic and ergonomic design is lacking
Solution Approach 1:
Dividing the push bar into face piece and reinforcing piece allows each component to be manufactured independently with optimized geometries for both aesthetics and structural requirements, then assembled together.
Solution Approach 2:
Different parts of the push bar have different properties: the face piece is optimized for user interaction and aesthetics, while the reinforcing piece is optimized for structural strength. This local differentiation allows each part to excel at its specific function.

AI summary
An actuation mechanism for a water dispenser having a housing includes a push bar exposed through an opening of the housing and configured for user engagement, and a hinge mechanism pivotably mounting the push bar on the housing to be pivotable between a rest position and an activation position, where the push bar is pivoted to engage an activation member of the dispenser, and a service position, where the push bar permits access to an internal component of the dispenser through the opening. The hinge mechanism includes hinge arms connected to the push bar and a hinge connection configured for connecting the hinge arms to the housing to permit pivoting of the hinge mechanism and the push bar. The push bar may include a face piece for user engagement and a reinforcing piece behind the face piece that has greater strength and/or stiffness than the face piece.
