CT Scanner Wireless Controller for Flexible HMI Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CT machines are limited by wired connections, restricting the placement of human-machine interface (HMI) control components and requiring multiple components at different positions for various control demands, which complicates operations and exposes operators to unnecessary radiation.
Innovation Solution
A wireless control system comprising a wireless main controller and secondary controllers, which use pairing sequences and verification codes to ensure reliable communication and operation, allowing flexible placement of control components and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wired HMI control components are used, then control reliability is ensured, but the placement positions are restricted by cable length and topology
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The wireless HMI control components communicate with the CT machine through wireless signals, eliminating the need for physical cables and connectors. This substitution enables flexible placement of control components without being constrained by cable length or topology, directly resolving the technical contradiction between placement flexibility and device complexity.
2Adaptability or versatility
If multiple wired HMI control components are deployed at different positions, then different control demands are fulfilled, but the system complexity increases
Solution Approach 1:
The patent implements a universal wireless control system where a single wireless HMI control component can serve multiple control demands. The wireless controller can dynamically adapt to different control scenarios (exposure control, movement control, etc.) without requiring separate dedicated components for each function. This multi-functionality approach reduces the total number of components needed while maintaining comprehensive control coverage across different positions and operations.
3Ease of operation
If operators perform control in the operating room, then simple movement control is convenient, but operators are exposed to unnecessary radiation
Solution Approach 1:
The patent introduces a wireless communication system as an intermediary between the operator and the CT machine controls. The wireless HMI control components enable operators to control the CT machine from a remote location (such as a control room) without physically being in the operating room where radiation is present. This intermediary wireless transmission mechanism allows operators to maintain control convenience while eliminating harmful radiation exposure.
