Solution Overview

Problem

Existing wall-mounted dispensers for liquids like soap and shampoo are complex to produce and difficult to handle, with limited design options due to separate connecting elements and non-circular storage bottle shapes, which complicates secure attachment and replacement of refill units.

Innovation Solution

A wall-mounted dosing dispenser with a connecting element designed as a closure cap for the bottle neck and a fastening hook that secures the refill unit against axial and rotational movement, integrated with an anti-theft mechanism for secure and easy attachment and tamper-evidence, allowing for a cylindrical storage container and simplified design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate connecting element is used to attach the refill unit to the wall bracket, then the attachment can be secured, but the production complexity increases and handling becomes more difficult

Engineering Contradiction:
Improveattachment securityVSAvoidproduction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the connecting element with the closure cap into a single integrated component. The closure cap serves dual functions: sealing the bottle opening and providing the connecting element for attachment to the wall bracket. This integration eliminates the need for separate connecting elements, reducing production complexity while maintaining secure attachment through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a non-circular storage bottle shape is used, then secure attachment is achieved, but design options are limited and production becomes more complex

Engineering Contradiction:
Improveattachment securityVSAvoiddesign options
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces asymmetry through the fastening hook and its corresponding depression rather than requiring a non-circular bottle shape. The fastening hook engages with a depression on the bottle, providing secure attachment and preventing rotation, while the bottle itself can maintain a simple cylindrical shape. This approach preserves design flexibility and production simplicity while achieving secure attachment.

Inventive Principle:
Principle #4Asymmetry

3Reliability

If an anti-theft device with latching hook is added, then unauthorized removal is prevented, but the device complexity increases

Engineering Contradiction:
Improvetamper evidenceVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The latching hook is integrated into the existing connecting element structure, serving both as the attachment mechanism and as the anti-theft device. The latching hook engages with the wall bracket to prevent unauthorized removal, while the same structure facilitates legitimate refilling operations. This multi-functional design provides tamper evidence without requiring a completely separate anti-theft mechanism, thus minimizing additional complexity.

Inventive Principle:
Principle #6Universality (Multi-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 simplifies the production and handling of the dispenser, provides a secure and aesthetically pleasing design with enhanced attachment security, and prevents unauthorized refill unit replacement, offering a wider range of design possibilities.

Implementation Method 1

by means of a release tool that can be inserted into the anti-theft device, can be moved from a locking or latching position against the inherent elasticity of the hook material, which serves as a restoring force, into a release or unlocked position

AI summary

The invention relates to a wall-mounted metering dispenser (1) for liquids, comprising a wall mounting element (2), on which a reservoir (3) is detachably mounted, which is made of an elastic material and which is exposed at least in an elastic sub-region of the reservoir wall thereof and to which compressive force can be applied and from which the liquid can be removed by means of the removal device, which can be actuated by applying compressive force to the reservoir wall. The reservoir (3) and the removal device form an exchangeable refilling unit, which can be detachably connected to the wall mounting element (2) at two fastening points (4, 5) that are spaced from each other, of which a first fastening point (4) is designed as a connecting element detachably mounted on the wall mounting element (2) and of which a second fastening point engages at the end face area of the reservoir (3) facing away from the connecting element (6) in such a way that the refilling unit can be installed between the fastening points (4, 5) in such a way that the refilling unit is secured against forces acting in the longitudinal and transverse directions of the wall-mounted metering dispenser (1). The wall-mounted metering dispenser according to the invention is characterized in that the second fastening point (5) has a fastening hook (10) that protrudes beyond the wall mounting element (2). In the mounted position of the refilling unit, the fastening hook is inserted into a shape-adapted depression (11) provided at least on the end face area of the reservoir (3) facing away from the connecting element (6) in such a way that the refilling unit is also secured against swiveling about the longitudinal axis of said refilling unit.
