Wall-mounted metering dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted metering dispensers for liquids, especially those with high viscosity, require users to apply pressure to discharge liquid, making precise metering difficult and operation non-intuitive, often resulting in liquid loss and increased cleaning complexity.
Innovation Solution
The dispenser is modified with a metering pump having a pump body with a pump chamber and valve, and an actuation element that can be moved relative to the container, featuring a discharge opening connected to the pump chamber via a discharge channel, allowing intuitive operation by pressing the actuation element to discharge liquid without relying on gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users apply pressure to the container to discharge liquid, then liquid can be discharged, but precise metering becomes difficult and operation becomes non-intuitive
Solution Approach 1:
The invention extracts the discharge function from the container itself and relocates it to a dedicated removal apparatus with a discharge opening. Users interact with the removal apparatus (pressing the actuation element) rather than applying pressure to the container, which separates the metering function from the discharge function and enables precise control.
Solution Approach 2:
The removal apparatus acts as an intermediary between the user and the liquid. Instead of directly pressing the container, users press the actuation element of the removal apparatus, which then controls the discharge through the pump mechanism. This intermediary provides intuitive feedback and precise metering.
2Adaptability or versatility
If the removal apparatus is integrated into the container, then the upper region can be retained, but the discharge opening is not directly accessible to users
Solution Approach 1:
The invention repositions the discharge opening from the upper region (hidden from users) to the actuation element in the lower region (directly accessible to users). This spatial reconfiguration in another dimension allows users to directly interact with the discharge opening while the removal apparatus remains integrated into the container's upper region for retention purposes.
3Ease of operation
If gravitational force is used for liquid removal, then simple discharge is achieved, but high viscosity liquids cannot be discharged within acceptable time
Solution Approach 1:
The invention replaces the gravitational mechanical system with a pump-based mechanical system. The pump mechanism (peristaltic, diaphragm, or piston pump) actively pushes high viscosity liquids through the discharge channel, overcoming the limitations of gravity and enabling rapid discharge of viscous substances while maintaining operational simplicity for users.
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
This design ensures stable and precise liquid dispensing, reducing liquid loss and complexity, as the user can directly actuate the discharge opening, improving usability and hygiene by preventing unauthorized access and ensuring secure container attachment.
Implementation Method 1
a pump body (17) which can be inserted in the removal opening (15) of the container and which has a pump chamber and pump valve and an actuation element (10) which can be moved relative to the container and which is constructed for mechanical cooperation with the pump valve and which has a discharge opening (12) for the liquid which is connected to the pump chamber via a discharge channel (11)
Implementation Method 2
The removal apparatus has to be provided with a valve which directly or indirectly closes the upper region of the container and which is opened by the user only in order to remove the liquid
Implementation Method 3
a user holds his/her hand under the removal apparatus, from which the liquid falls downward

AI summary
A wall-mounted metering dispenser for a liquid, having a replaceable container and a wall bracket, and having a removal apparatus for removing liquid from the container in a metered manner. The wall bracket has a first fixing location having a fixed retention element for the base region of the container, and a second fixing location having a sleeve which can is separable from or movable relative to the wall bracket which retains the upper region of the container. The removal apparatus is arranged on or integrated in the sleeve and includes a metering pump having a pump chamber that is insertable in the container opening and a pump valve and an actuation element that is movable relative to the container and cooperates with the pump valve and has a liquid discharge opening connected to the pump chamber via a discharge channel. The actuation element is guided in the sleeve.
