Terminal Device Display Control for Medical Information Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal devices used in medical treatment or care facilities may display outdated information due to network or server issues, potentially providing unsuitable information to patients and medical staff.
Innovation Solution
A terminal device equipped with an acquisition unit to receive and store information from a server, and a display controller that stops displaying biological information when a display stop condition is met, indicating a likelihood of information discrepancy, and resumes display when updated information is confirmed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device continuously displays information from the server, then information availability is maintained, but outdated or unsuitable information may be provided when network or server troubles occur
Solution Approach 1:
The display controller stops displaying biological information in advance when a display stop condition is detected (such as network trouble or server unresponsiveness), before outdated information can be provided. This preliminary action prevents the propagation of unreliable information while maintaining the ability to resume display once conditions improve.
Solution Approach 2:
The system continuously monitors the connection status between the terminal device and the server, using this feedback to dynamically control the display. When the display stop condition is satisfied (indicating likely information discrepancy), the display controller stops displaying biological information. When the condition is no longer satisfied, display resumes normally.
2Productivity
If the terminal device stores information in memory to ensure continuous display, then information availability is maintained, but the risk of displaying outdated information increases
Solution Approach 1:
The system performs preliminary actions by stopping the display of biological information when network or server issues are detected, before outdated stored information can be mistakenly displayed. This prevents the productivity benefit of continuous display from becoming a reliability hazard.
Solution Approach 2:
The display state is made dynamic rather than static. The display controller adjusts the display state based on real-time connection status, transitioning between displaying and stopping display according to whether the display stop condition is satisfied. This dynamic adaptation allows the system to maintain both continuity and accuracy.
3Reliability
If the terminal device monitors network status to prevent outdated information display, then information reliability is improved, but system complexity increases
Solution Approach 1:
The display controller performs multiple functions: it controls the display output, monitors the display stop condition (network status), and decides whether to stop or resume display. By making the display controller multi-functional, the system avoids adding separate monitoring hardware or complex independent monitoring mechanisms.
Solution Approach 2:
The terminal device monitors its own network status and server connection state internally, without requiring external monitoring systems. The display controller uses its existing resources to detect the display stop condition and control display output, making the system self-sufficient and reducing overall complexity.

AI summary
This terminal device is provided with: an acquisition unit which receives, from a server, information displayed on a display device used for medical treatment or care, and stores the received information in a storage unit; and a display control unit which displays the information on the display device. When a display stop condition, which indicates the likelihood that there is a difference between information stored in the server and information stored in the storage unit, is satisfied, the display control unit stops the display of at least information about biological information on a facility user who is a person requiring the medical treatment or care, among the information on the display device.
