Wall-Mounted Dosing Dispenser with Pump for Viscous Liquid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted dispensers for liquids, especially those with high viscosity, require users to exert force to dispense the liquid, leading to difficulties in exact dosing and potential liquid loss due to non-intuitive operation and the need to apply pressure, which can result in more liquid being taken than intended.
Innovation Solution
A wall-mounted dosing dispenser with a dosing pump featuring a pump body and actuating element that can be inserted into the container's removal opening, allowing for intuitive operation by pressing the dispensing opening, which is visible to the user, and a secure attachment system to prevent unauthorized access and ensure hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If users apply pressure to the container to dispense liquid, then liquid can be removed from high viscosity containers, but exact dosing becomes difficult and liquid loss increases
Solution Approach 1:
A pump mechanism acts as an intermediary between the user and the liquid. The pump includes a pump head that receives liquid from the container and a discharge outlet that delivers measured liquid to the user. This intermediary system allows controlled liquid transfer without requiring direct user manipulation of the liquid stream, enabling precise dosing while maintaining the ability to handle high viscosity liquids through the pump's mechanical action.
Solution Approach 2:
The invention replaces the direct mechanical pressure application on the container with a pump-based mechanical system. Instead of squeezing the container directly, the user activates a pump mechanism that mechanically transfers liquid from the container through a controlled path to the discharge outlet. This substitution provides mechanical advantage and control, enabling precise dosing while maintaining effectiveness with high viscosity liquids.
2Ease of operation
If the dispensing opening is positioned below the container for gravity-assisted flow, then liquid can flow naturally, but the opening becomes invisible to users and operation is non-intuitive
Solution Approach 1:
The invention repositions the dispensing function from a vertical orientation (below the container) to a horizontal or forward-facing orientation (at the front of the dispenser). The pump's discharge outlet is positioned on the front surface of the dispenser body, making it visible and accessible to users. This dimensional change allows users to see and interact with the dispensing opening intuitively while the pump mechanism handles the liquid transfer from the container.
3Reliability
If the container is attached securely to prevent theft, then hygiene and security are improved, but container replacement becomes more complex
Solution Approach 1:
The attachment system is segmented into modular components: a container with attachment features, a dispenser body with receiving structures, and a pump mechanism that can be independently serviced. The container attaches to the dispenser body through simplified mechanical interfaces (such as snap-fit or bayonet mounts) that provide secure attachment during use but allow for easy one-handed removal when needed. This segmentation enables both security during operation and simplicity during replacement.

AI summary
The invention relates to a wall-mounted dispenser for dispensing and removing a liquid, in particular a washing-active substance or a personal care product, with an interchangeable container 1 for the liquid and with a wall bracket 2 for attaching the wall-mounted dispenser to a building structure, as well as with a dispensing device for metered removal of liquid from the container 1.The container 1 has a base section 6 with a container bottom and, opposite this, a head section 9 with a dispensing opening 15. The wall bracket 2 has two spaced-apart mounting points 3, 7 for the container 1. A first mounting point 3, 7 is provided with a stationary retaining element for the base section 6 of the container 1, into which the container 1 can be inserted or to which the container bottom can be attached in order to hold the base section 6 of the container 1 positively and/or non-positively at the first mounting point 3. A second mounting point 7 has a sleeve 8, which is detachable from or movable relative to the wall bracket 2 and can be fixed to the wall bracket 2, for holding the head section 9 of the container 1. The dispensing device is arranged on the sleeve 8 or at least partially integrated into it.Furthermore, the dispensing device is designed as a metering pump, which comprises a pump chamber with a pump valve that can be inserted into the dispensing opening 15 of the container 1, and an actuating element 10 that is movable relative to the container 1. The actuating element 10 is designed to interact mechanically with the pump valve and has a discharge opening 12 for the liquid, which is connected to the pump chamber via a discharge channel 11. The actuating element 10 is guided in the sleeve 8.
