Mobile C-Arm X-Ray Trolley With Grip-Sensing Motion Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile X-ray devices lack intuitive and efficient movement control, requiring manual selection of movement profiles by the operator, which can be cumbersome and time-consuming, especially in different contexts such as moving between rooms and precise positioning in an operating room.
Innovation Solution
A mobile medical device with a device trolley that can be moved in at least two motor-assisted movement modes, equipped with gripping elements and sensors to capture hand gripping characteristics, allowing automatic setting of movement modes based on the operator's grip, thereby simplifying operation and enhancing maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual selection of movement profiles is used, then device control is simple, but operational efficiency is reduced and time is lost
Solution Approach 1:
The system automatically detects the operator's gripping behavior and autonomously selects the appropriate movement profile without requiring manual intervention. The control unit evaluates measurement data from sensors to determine whether the device should move quickly between rooms or slowly for precise positioning, making the system self-serve the movement mode selection based on observed operator intent.
2Adaptability or versatility
If multiple movement modes are provided for different contexts, then adaptability is improved, but ease of operation deteriorates due to manual mode selection
Solution Approach 1:
The system incorporates sensors that continuously monitor the operator's gripping behavior on the gripping element. Based on this feedback, the control unit automatically determines the appropriate movement mode - for example, detecting whether the operator grips with one hand or two hands, or the force applied, to infer whether quick transport or precise positioning is intended, thereby adapting the movement mode without requiring the operator to manually select it.
3Loss of time
If automatic movement mode setting is implemented, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The patent replaces the manual mechanical selection process with an automated sensor-based detection system. Instead of requiring the operator to physically switch between movement modes using buttons or switches, the system uses sensors to detect gripping characteristics and automatically triggers the appropriate movement profile through electronic control, substituting mechanical interaction with automated sensing and control.
