Solution Overview

Problem

Wall-mounted pump dispensers in guest accommodations face issues of unauthorized removal and contamination risks due to their design, which allows for repeated use and potential transfer of contaminated liquids.

Innovation Solution

A wall-mountable bracket with an upright member, basal support, and a pivotable retainer member that secures the pump dispenser at the closure, featuring a lockable mechanism to prevent unauthorized removal and enhance security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a pump dispenser is mounted on a wall for repeated use, then convenience of operation is improved, but the risk of unauthorized removal and contamination increases

Engineering Contradiction:

Improveconvenience of operationVSAvoidrisk of unauthorized removal and contamination

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The bracket is divided into distinct functional segments: a basal support for stable mounting, an upright member for structural support, and a retainer member for secure engagement. This segmentation allows each component to perform its specific function optimally while working together to prevent unauthorized removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The retainer member is designed to be movable between a first position for engaging the dispenser and a second position for release. This dynamic capability allows the system to transition between secured and accessible states, providing both security during use and ease of replacement when needed.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a pump dispenser is installed in a shower recess, then ease of operation is improved, but the likelihood of unauthorized removal increases

Engineering Contradiction:

Improveease of operationVSAvoidunauthorized removal

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The retainer member features a curved engagement surface that complements the shape of the dispenser closure. This curved geometry provides a secure mechanical interlock that resists unauthorized removal attempts while allowing legitimate users to access the dispenser through the designed release mechanism.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The bracket integrates multiple security functions into a single unified structure: the basal support prevents lateral displacement, the upright member provides structural integrity, and the retainer member secures the dispenser to the bracket, creating a comprehensive anti-theft solution.

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If a pump dispenser is designed for numerous repeated uses, then productivity is improved, but the risk of liquid contamination increases

Engineering Contradiction:

ImproveproductivityVSAvoidliquid contamination

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The bracket system is designed to securely hold and protect a single dispenser unit, encouraging the use of disposable or single-tenant dispensers. This approach allows each guest to have their own dedicated dispenser that can be securely mounted and then disposed of or replaced, eliminating cross-contamination risks while maintaining high productivity.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

4Reliability

If a retainer member is added to secure the dispenser, then reliability is improved, but device complexity increases

Engineering Contradiction:

ImprovereliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The retainer member is designed to be self-retaining through its engagement with the dispenser closure. Once positioned in the first position, the curved engagement surface and geometric constraints automatically maintain the secured state without requiring additional locking mechanisms or complex control systems.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The retainer member serves multiple functions: it secures the dispenser to the bracket, prevents unauthorized removal, and provides a release mechanism for legitimate access. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A wall-mountable bracket for mounting a pump action dispenser has an upright member, a basal support projecting outwardly from a lower end of the upright member, a tab projecting outwardly from an upper end of the upright member, above the basal support, and a retainer member adjustably mounted on and projecting outwardly from the tab above the basal support. The retainer member is adapted for engaging the pump action dispenser supported on the basal support in an upright position adjacent the upright member, and adjustable to releasably secure the pump action dispenser.
