X-ray Fluoroscopic Imaging Operation Panel Emergency Stop Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray fluoroscopic imaging apparatuses with emergency stop units have increased protruding height due to the need for a single button to perform both emergency stop and release operations, making it difficult to thin the operation panel and increasing the risk of unintentional operations.
Innovation Solution
The emergency stop unit and stop state release unit are provided separately at different positions, each configured as a simple operation input unit that can be operated with a single action, reducing the protruding height and minimizing unintentional contacts by being recessed within surrounding regions on the operation panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single mushroom-shaped push button is used to perform both emergency stop and release operations, then the number of operation input units is reduced, but the protruding height of the emergency stop unit is increased
Solution Approach 1:
The patent divides the emergency stop function into two separate operation input units: an emergency stop unit and a release unit. This segmentation eliminates the need for a multi-functional mushroom-shaped button, allowing each unit to have a simpler, lower-profile structure while maintaining the required safety functions.
2Area of stationary object
If a single button with multiple operations is used, then the operation panel can be compact, but the protruding height increases making it difficult to thin the operation panel
Solution Approach 1:
By segmenting the emergency stop and release operations into separate buttons, each button can be designed with minimal protruding height. The combined width of two low-profile buttons is less than the protruding height of a single multi-functional button, thus thinning the overall operation panel.
3Ease of operation
If the emergency stop unit protrudes significantly, then it is easily accessible, but the risk of unintentional operations increases
Solution Approach 1:
The patent applies different local qualities to the two separate buttons: the emergency stop unit has a pressed surface that protrudes from the operation panel surface for easy accessibility, while the release unit has a pressed surface that is recessed to prevent unintentional activation. This differentiated design allows each button to have optimal characteristics for its specific function.

AI summary
An X-ray fluoroscopic imaging apparatus includes a table, an imaging system including an X-ray source and a detector, and an operation panel unit including a plurality of operation input units. The plurality of operation input units include an emergency stop unit and a stop state release unit. The emergency stop unit and the stop state release unit are provided separately from each other at different positions.
