Solution Overview

Problem

Current mobile x-ray systems require operators to wait for the tube arm to return to a fully parked position before collapsing the column, which is time-consuming, especially in fast-paced environments like intensive care units or emergency rooms, hindering efficient patient-to-patient transitions.

Innovation Solution

The system allows for concurrent collapsing of the column while driving the mobile imaging system by using sensors and actuators to control the tube arm and column movements, enabling the column to collapse to an end position while the cart is in motion, facilitated by force feedback mechanisms and position sensors to adjust speeds and positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the operator waits for the tube arm to return to a fully parked position before collapsing the column, then the system ensures safe and stable operation, but the transition time between imaging and transport configurations increases

Engineering Contradiction:
Improvesafe operationVSAvoidtransition time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The tube arm automatically returns to the parked position and latches upon release of the first handle, preparing the system for column collapse in advance. This preliminary positioning eliminates the need for manual intervention and reduces waiting time before the column can begin collapsing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The column collapse operation begins immediately after the tube arm parks, creating a continuous sequence of actions. The system transitions from imaging to transport configuration without idle waiting periods, maintaining continuous productive action throughout the reconfiguration process.

Inventive Principle:
Principle #20Continuity of useful action

2Productivity

If the column collapses while the cart is in motion, then the transition speed increases, but the system complexity and control requirements increase

Engineering Contradiction:
Improvetransition speedVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Position sensors continuously monitor the tube arm position and provide feedback to the controller. The controller uses this feedback to determine when the tube arm has reached the parked position and to control the column collapse speed, ensuring safe operation even during cart motion.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically controls the column collapse operation without requiring manual intervention. The controller manages the entire sequence from tube arm parking to column collapse, reducing operator workload and simplifying the user interface while maintaining complex control functions.

Inventive Principle:
Principle #25Self-service

3Reliability

If the tube arm is manually positioned before column collapse, then operational safety is maintained, but the operator workload and time consumption increase

Engineering Contradiction:
Improveoperational safetyVSAvoidoperator workload
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The tube arm automatically returns to the parked position and engages the latch mechanism upon release of the first handle. This self-positioning and self-latching function eliminates the need for manual intervention, reducing operator workload while maintaining operational safety through automated positioning.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical positioning of the tube arm is replaced with an automated motorized system. The first handle actuates a motor that automatically positions the tube arm and engages the latch, replacing manual mechanical operations with automated electromechanical control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
