Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical imaging devices, such as computed tomography apparatuses with a gantry, experience undesired natural vibration due to uneven distribution of application force over leveling feet, which can lead to instability and tipping during operation.
Innovation Solution
A method for mounting medical imaging devices involves using balancing plates to ensure uniform distribution of the application force over leveling feet, which are adjusted by applying a predetermined torque to achieve a balanced load distribution and minimize vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the height of leveling feet is adjusted to align the medical imaging device on an uneven supporting surface, then the device can be positioned correctly, but the application force is unevenly distributed causing vibration and potential tipping
Solution Approach 1:
The patent applies a predetermined torque parameter to the leveling feet during readjustment to achieve uniform load distribution. By controlling the torque applied to each leveling foot, the system changes the mechanical parameters of the mounting system to ensure equal force distribution, thereby reducing vibration while maintaining alignment stability.
2Object-affected harmful factors
If load distribution over leveling feet is measured to ensure uniform force distribution, then vibration can be minimized, but the measurement process is technically complex and difficult without changing the installation state
Solution Approach 1:
The patent employs a self-service approach where the leveling feet themselves indicate the load distribution status through their adjustment state. By reading the position of the leveling feet after applying predetermined torque, the system determines load distribution without requiring external measurement devices or complex instrumentation, thus minimizing vibration assessment complexity.
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 method effectively reduces vibration and ensures stable operation of medical imaging devices by uniformly distributing the load over the leveling feet, thereby preventing tipping and improving the overall alignment of the device.
Implementation Method 1
The leveling feet have a pitch thread, for example, with which they are screwed into the medical imaging device, so as to enable height adjustment of the medical imaging device. Leveling out of the roughness of the supporting surface results in known, constant frictional behavior between the at least one leveling foot and the balancing plate beneath it.
Implementation Method 2
readjusting the at least one leveling foot on the at least one balancing plate by applying a predetermined torque, wherein the predetermined torque is sufficiently great for a predetermined load to be achieved on the at least one leveling foot during readjustment
