Solution Overview

Problem

Existing liquid product dispensers for hotel rooms require costly spring-based magnetic locking mechanisms, increasing manufacturing and assembly costs, and lack an improved locking mechanism that does not rely on springs.

Innovation Solution

A magnetic locking mechanism for a counter-top mounting device that uses a pivoting locking arm and an annular groove to secure the dispensing container, eliminating the need for a spring by employing a magnetic locking post that can be unlocked with a magnet, thereby reducing production costs and simplifying assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a spring-based magnetic locking mechanism is used, then the dispensing container can be securely locked, but the manufacturing and assembly costs increase

Engineering Contradiction:
Improvelocking securityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent removes the spring component from the locking mechanism, extracting the problematic element that caused high manufacturing costs while maintaining the magnetic locking function through a simplified design with a locking arm and annular groove

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces expensive reusable spring components with a simpler magnetic locking system that uses inexpensive materials, achieving cost-effective manufacturing without compromising the essential locking function

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If a spring-based magnetic locking mechanism is used, then the dispensing container can be securely locked, but the assembly complexity increases

Engineering Contradiction:
Improvelocking securityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

By removing the spring component entirely, the patent simplifies the assembly process and reduces the number of parts that need to be assembled, while the magnetic locking arm and annular groove provide sufficient locking security

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The magnetic locking mechanism automatically engages and disengages without requiring manual spring compression or complex assembly steps, allowing the system to self-regulate the locking action through magnetic attraction and release

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If a magnetic locking post is used without a spring, then manufacturing costs are reduced, but the locking mechanism must be redesigned

Engineering Contradiction:
Improvemanufacturing costVSAvoidmechanism design
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

Instead of using a spring to push a magnetic post upward for locking, the patent inverts the approach by using a magnetic locking arm that pivots downward to engage with an annular groove, eliminating the need for spring biasing while achieving secure locking

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

A mounting device has a locking housing with a locking arm that pivots between an open, unlocked position, and a closed, locked position. The locking arm extending to a latch end having a latch hole. A bottom end of the dispensing container is placed within a container receiving space of the locking housing, and the locking arm is moved to the closed, locked position to engage the annular groove of the dispensing container to lock the dispensing container within the locking housing. The device further includes a magnetic locking mechanism for locking the locking arm in the closed, locked position.
