MRI Emergency Stop Mounting With Rotating Locking Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MRI scanners with unitary front covers require the entire front cover to be removed for emergency stop assembly replacement or installation, which is cumbersome due to their large size and weight.
Innovation Solution
A receiving plate mounted to the inner surface of the front cover with a locking bracket system allows the emergency stop assembly to be installed and removed without taking off the entire front cover, using engagement flanges and a locking assembly for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire front cover is removed for emergency stop assembly replacement, then the emergency stop assembly can be accessed and replaced, but the operation becomes cumbersome due to the large size and weight of the front cover
Solution Approach 1:
The front cover is divided into two functional parts: a fixed portion that remains attached to the MRI scanner and a removable portion that can be detached to access the emergency stop assembly. This segmentation allows the heavy front cover to be partially removed without requiring complete detachment, thereby reducing the operational burden while maintaining access to the emergency stop assembly.
Solution Approach 2:
The emergency stop assembly is extracted from the interior of the front cover and mounted on the outer surface of the front cover. This external mounting allows the emergency stop assembly to be accessed by simply removing a small access panel or cover, rather than requiring removal of the entire heavy front cover, thus improving ease of operation while leaving the main front cover structure in place.
2Shape
If a unitary front cover is used to enhance appearance, then the aesthetic integrity is improved, but the difficulty of removing and replacing the emergency stop assembly increases
Solution Approach 1:
The unitary front cover incorporates a segmented access mechanism with a removable access panel that can be detached to expose the emergency stop assembly mounting location. This allows the front cover to maintain its unitary aesthetic appearance while providing a practical access path for emergency stop assembly installation and replacement through the removable panel portion.
Solution Approach 2:
An intermediary access panel or cover is introduced between the user and the emergency stop assembly mounting location. This intermediary component can be easily removed to provide access to the emergency stop assembly while remaining attached to the unitary front cover structure, thus preserving the overall aesthetic integrity while enabling ease of repair and maintenance.
3Stability of the object's composition
If the emergency stop assembly is mounted on the inner surface of the front cover, then secure attachment is achieved, but access to the mounting location requires complete front cover removal
Solution Approach 1:
The front cover is segmented to include a removable access panel that provides direct access to the emergency stop assembly mounting location on the inner surface. This segmentation allows technicians to access the mounting location by removing only the small access panel rather than the entire front cover, significantly reducing the time required for assembly replacement while maintaining secure attachment of the emergency stop assembly to the inner surface.
Solution Approach 2:
The emergency stop assembly is pre-mounted on the inner surface of the front cover at the desired location before the final assembly is completed. This preliminary mounting action allows the assembly to be securely attached in its final position, and future replacements can be performed by simply accessing the pre-prepared mounting location through the removable access panel, eliminating the need for complete front cover removal and reducing replacement time.

AI summary
An arrangement for an imaging scanner, such as an MRI scanner, to position an emergency stop assembly on the scanner. The scanner includes a front cover having an inner and an outer surface. A receiving plate is mounted to the inner surface of the front cover. A locking bracket is coupled to the emergency stop assembly. The locking bracket is positioned on the receiving plate and rotated relative to the receiving plate to move between a release position and a locking position. The locking bracket includes engagement flanges that are received and retained in receiving slots of the receiving plate. A locking assembly is position adjacent to the receiving plate and is operable between engaged and disengaged positions. In the engaged position, the locking assembly prevents movement of the locking bracket away from the locking position. A method is provided for mounting the emergency stop assembly to the imaging scanner.
