Magnetic Locking Ring for Pump Head Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage system pumps require additional labor due to the need for tools to secure and remove locking rings, which can lead to leakage issues when the locking ring moves during operation.
Innovation Solution
A locking ring with a magnet that is detected by a sensor when in a locked position, which communicates with a controller to stop the pump operation if the ring moves from the locked position, eliminating the need for screws and preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to secure the locking ring to the adapter plate, then the locking ring is firmly secured, but additional labor and tools are required for installation and removal
Solution Approach 1:
The patent replaces the mechanical screw-fastening system with a friction-fit locking mechanism combined with magnetic detection. The locking ring engages with the adapter plate through friction and geometric interlocking, eliminating the need for screws. A magnet embedded in the locking ring interacts with a sensor to provide automatic position detection, replacing manual verification methods.
Solution Approach 2:
The locking ring incorporates a built-in magnet that automatically interacts with the sensor system to indicate its position. This self-service mechanism eliminates the need for external tools or additional manual steps to verify locking status, as the system autonomously detects and communicates the locking ring's position.
2Strength
If a tool is required to secure and remove the locking ring, then the locking ring can be firmly attached, but additional labor is required
Solution Approach 1:
The patent replaces tool-based mechanical fastening with a tool-free friction-fit system. The locking ring's design incorporates geometric features that create sufficient friction and mechanical interlocking to securely attach the adapter plate to the pump head without requiring screws or specialized tools, thereby eliminating the time required for tool-based assembly and disassembly.
3Ease of operation
If the locking ring can move during operation, then ease of adjustment is improved, but leakage occurs
Solution Approach 1:
The patent implements a feedback mechanism where a sensor continuously monitors the position of the locking ring through magnetic interaction. When the locking ring moves from its properly positioned state, the sensor detects the change and can trigger alerts or shutdowns, preventing leakage conditions. This feedback loop ensures the locking ring remains in the correct position without requiring physical constraints that would eliminate adjustment flexibility.
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 installation and operation of the locking ring, reducing labor requirements and preventing leakage by automatically shutting down the pump if the ring is not properly secured, thus enhancing operator safety and system efficiency.
Implementation Method 1
The locking ring includes a projection with a magnet pocket that receives a magnet. When the locking ring is in the locked position, the magnet is detected by a reed switch.
Data Source
AI summary
A beverage system includes a pump that draws a set amount of a flavored concentrate into a mixing chamber for mixing with water to form a beverage. A locking ring attaches an adapter plate to a pump head. When the locking ring is in a locked position, a magnet of the locking ring is detected by a reed switch. If the locking ring rotates from the locked position, the reed switch does not detect the magnet, indicating that the locking ring, and therefore the pump head, is incorrectly or not completely installed. The controller then stops operation of the pump.
