Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional apparatuses for manipulating magnetic particles in tubular containers are prone to unstable door closure, leading to unintended opening and instability in maintaining the container position during magnetic field manipulation.
Innovation Solution
The apparatus incorporates a latch mechanism with a pivoting part and an engaging part, where the pivoting part is pivotable about a pivot axis, and the engaging part applies a force to maintain the door in a closed state, preventing unintended opening and ensuring stability by adjusting the contact point and pivot axis positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple door closure mechanism is used, then the device complexity is reduced, but the door stability and reliability deteriorate, leading to unintended opening
Solution Approach 1:
The latch mechanism is designed to automatically engage and maintain the door in a closed state through self-locking action. The pivoting part and engaging part work together to provide automatic latching without requiring external intervention, ensuring the door remains stable while using minimal structural complexity.
Solution Approach 2:
The patent replaces complex mechanical fastening systems with a simpler latch mechanism based on pivoting and engaging parts. This substitution maintains reliability through the self-locking action of the latch while significantly reducing the overall complexity of the door closure system.
2Ease of operation
If the door is made easily openable, then the ease of operation is improved, but the stability of the container position deteriorates during magnetic field manipulation
Solution Approach 1:
The door mechanism incorporates a pivoting part that can dynamically transition between latched and unlatched states. This dynamic design allows the door to be easily opened when needed while maintaining stable closure during operation, balancing ease of operation with position stability through controlled movement.
Solution Approach 2:
The latch mechanism provides automatic latching that maintains container stability during magnetic field manipulation. The self-locking action ensures the door remains securely closed without requiring additional fastening mechanisms, while still allowing easy manual opening when required.
3Force
If the contact point is positioned far from the pivot axis, then the force leverage is improved, but the device complexity increases due to longer engagement arms
Solution Approach 1:
The latch mechanism employs asymmetric geometry where the pivoting part and engaging part are positioned to create effective leverage. The contact point is strategically located to provide sufficient latching force while maintaining a compact overall structure, avoiding the need for excessively long engagement arms that would increase complexity.

Function Achieved in This Case
This configuration effectively maintains the door in a stable closed state, preventing accidental opening and ensuring accurate positioning of the container relative to the magnetic field application part, thereby stabilizing the magnetic particle manipulation process.
Implementation Method 1
The magnetic field application part is provided in the main body, and moves relative to the container held by the main body to change the magnetic field, so as to move the magnetic particles in the container

AI summary
An apparatus for manipulating magnetic particles includes a latch mechanism. The latch mechanism has a pivoting part provided on a door and an engaging part provided on a main body. In the apparatus for manipulating magnetic particles, a first contact portion of a latch engages with the engaging part at a contact point in a state that the door is closed. The contact point is located more outside of the main body than the pivot axis. Accordingly, in a case where an external force is applied to the door in a direction to open the door in a state that the door is closed, a force is applied from the engaging part to the first contact portion, thereby generating a rotational force in a C direction to the pivoting part. As a result, in the state that the door is closed, it is possible to suppress the door from being opened without a manipulation by the user.
