Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrocardiogram display devices have a fixed display mode, requiring manual adjustment and significant training to change the arrangement of electrocardiogram waveforms, which hinders efficient analysis and understanding of myocardial activity.
Innovation Solution
An electrocardiogram display device with a waveform generating unit, arranging instruction unit, and displaying control unit that allows users to input and change the arrangement of electrocardiogram waveforms from one mode to another, such as switching between standard 12-lead and Cabrera lead modes, and automatically adjusts the display based on screen orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display mode is fixed in standard 12-lead mode, then the device structure is simple, but the ease of operation deteriorates because manual adjustment and extensive training are required to change the arrangement
Solution Approach 1:
The patent implements dynamic display mode switching that allows the electrocardiogram display to transition between standard 12-lead mode and Cabrera lead mode based on user input. The displaying control unit dynamically rearranges the waveform arrangement according to the selected mode, making the display adaptable rather than fixed, thereby improving ease of operation without requiring extensive training.
2Adaptability or versatility
If the display mode is fixed, then the device complexity is low, but the adaptability deteriorates because the device cannot automatically adjust to different display requirements
Solution Approach 1:
The patent introduces dynamic adaptability through the arranging instruction unit and displaying control unit, which automatically adjust the waveform arrangement based on user input. The system can switch between standard 12-lead mode and Cabrera lead mode, allowing the display to adapt to different analytical requirements without manual reconfiguration, thereby enhancing versatility.
Solution Approach 2:
The system performs self-service by automatically executing the waveform arrangement changes based on user selection. When a user inputs a request to switch display modes, the displaying control unit automatically retrieves the appropriate arrangement from memory and applies it without requiring manual adjustment, enabling the device to serve itself in the adaptation process.
3Loss of time
If manual adjustment of display mode is required, then the device structure remains simple, but the loss of time increases because significant training and time are needed to acquire skills for manual adjustment
Solution Approach 1:
The patent eliminates time loss by implementing self-service functionality where the displaying control unit automatically executes waveform arrangement changes based on user input. When a user selects a different display mode, the system automatically retrieves and applies the corresponding arrangement from memory, eliminating the need for manual adjustment and the time required to acquire expertise in manual configuration.
Solution Approach 2:
The patent applies preliminary action by pre-storing multiple waveform arrangements (standard 12-lead mode and Cabrera lead mode) in memory before the user needs them. When the user inputs a request to switch modes, the system can immediately retrieve the pre-prepared arrangement without requiring real-time calculation or manual configuration, thereby reducing time loss.
