Drinking Vessel Intake Marker with Magnetic Locking Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinking vessels with display value settings are prone to unintentional misalignment, particularly in cases involving individuals with dementia, leading to unreliable fluid intake monitoring, which cannot replace traditional written logs in care facilities.
Innovation Solution
A drinking vessel with a metal or magnetic strip and a marking element, where the marking element is slidably mounted on the strip and controlled by a separate actuating magnet, ensuring secure and authorized adjustment of the display value, preventing unintentional changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the marking element is freely movable on the scale element, then the device is easy to operate, but the marking element can be unintentionally misaligned
Solution Approach 1:
The patent introduces a separate actuating magnet that must be used to move the marking element. This preliminary action requirement ensures that only intentional adjustments made with the proper tool will move the marking element, preventing unintentional misalignment while maintaining ease of operation when the correct tool is used.
Solution Approach 2:
The patent uses a magnetic field as an intermediary between the actuating magnet and the marking element. The marking element is magnetically coupled to the scale element, and the actuating magnet temporarily overcomes this magnetic coupling to move the marking element to a new position, then the magnetic coupling restores to hold it in place.
2Reliability
If the marking element is securely attached to the scale element, then the alignment is stable, but the display value cannot be changed
Solution Approach 1:
The patent creates a dynamic system where the marking element's attachment state changes based on the presence of the actuating magnet. When the actuating magnet is absent, the marking element is securely attached to the scale element via magnetic force. When the actuating magnet is present, it temporarily overcomes the magnetic attachment to allow movement, then the attachment restores afterward.
Solution Approach 2:
The patent changes the magnetic field parameter by introducing an external actuating magnet with sufficient magnetic strength to temporarily overcome the magnetic coupling between the marking element and scale element. This parameter change enables movement only when needed, while maintaining secure attachment during normal operation.
3Ease of operation
If the marking element can be easily moved, then the device is user-friendly, but unauthorized changes cannot be prevented
Solution Approach 1:
The patent introduces a separate actuating magnet as an intermediary tool that mediates between the user and the marking element. This tool acts as a key or authorization mechanism - only someone with access to the actuating magnet can change the marking element's position, providing authorization control while maintaining ease of operation for authorized users.
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 provides a secure and reliable method for setting and displaying fluid intake, preventing unauthorized changes and ensuring accurate monitoring, thus addressing the limitations of prior vessels in care settings.
Implementation Method 1
controlled by a, in particular separate, actuating magnet, preferably contactlessly by means of magnetic force, is displaceable
Implementation Method 2
The marking element can be moved by means of magnetic force. The magnetic forces between the marker and the metal or magnetic element and between the marker and the actuating magnet are each an attractive force.
