Touch Input System for Electromedical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input systems for electromedical devices are prone to incorrect inputs due to accidental touching, which can have adverse consequences for patient health, and lack reliable detection of applicable control commands during different operating modes.
Innovation Solution
An input system comprising a touch-sensitive display with predefined command areas and a communication network that ensures correct input assignment by requiring the input area to be entirely within a command area and the command to be part of the currently executable group, with confirmation signals and error outputs to validate input actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch display is used for controlling an electromedical device, then the ease of operation is improved, but the reliability deteriorates due to accidental touching
Solution Approach 1:
The system performs preliminary verification by detecting the input area, comparing it with predefined command areas, and checking whether the touched command is currently executable before executing the control command. This preliminary action prevents accidental executions while maintaining ease of use.
Solution Approach 2:
The system provides feedback by displaying whether a touched command is currently executable and preventing execution if it is not. This feedback mechanism allows users to verify their input before execution, improving reliability without compromising the simplicity of touch operation.
2Productivity
If any control command can be executed at any time, then the productivity is improved, but the reliability deteriorates due to incorrect inputs during inappropriate operating modes
Solution Approach 1:
The system determines in advance which control commands are currently executable based on the operating mode before allowing execution. This preliminary check ensures that only appropriate commands can be executed, preventing incorrect inputs while maintaining efficient operation.
Solution Approach 2:
The set of executable control commands dynamically changes based on the current operating mode. The system adapts the available commands to the current state, allowing rapid execution of appropriate commands while preventing execution of inappropriate ones, thus maintaining both productivity and reliability.
3Ease of operation
If the input area is allowed to partially overlap with a command area, then the ease of operation is improved, but the manufacturing precision deteriorates in determining correct input assignment
Solution Approach 1:
The system performs preliminary verification by comparing the detected input area with the predefined command area to determine whether the input is correct before executing the control command. This preliminary precision check prevents incorrect executions while maintaining ease of operation.

AI summary
A input system (100), controlling an electromedical device (105), includes a network (110), an input unit (120) and a control unit (140). The input unit has a touch display (122) and detects an input area (125) and outputs an input signal (126) to the network via an input interface (128), if a comparison between the input area and a displayed control menu (130) makes possible an assignment, between the input area and the control command, if the input area is located within a command area (132) on the touch display, and if the control command is contained in a group of currently executable control commands. The control unit receives the input signal and outputs a control signal (142), based on the input signal, to the electromedical device for actuating the corresponding application and sends a confirmation signal (144) to the input unit after the output of the control signal.
