Blood Purification Display Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing blood purification apparatuses face difficulties in maintaining operability during the normal mode and visibility during the display mode, leading to challenges in smoothly confirming the operation status, especially when switching between these modes, which can be confusing for unfamiliar personnel.
Innovation Solution
A blood purification apparatus with a display device that automatically switches between normal and display modes based on proximity detection, maintaining the layout and form of the normal mode during the display mode, and omitting switch units in display mode to enhance visibility, while allowing touch panel inputs in normal mode, and automatically switching to normal mode upon alarm issuance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device uses different display forms for normal mode and display mode, then operability in normal mode and visibility from distance in display mode are improved, but it causes confusion and difficulty in confirming operation status when switching between modes
Solution Approach 1:
The display device dynamically changes its display form based on the detected distance to the user. When the user is close (within threshold distance), it displays in normal mode with detailed operational interface. When the user is far (beyond threshold distance), it switches to display mode with enlarged, simplified visual information. This dynamic adaptation resolves the contradiction by providing the appropriate display complexity for each operational context.
Solution Approach 2:
The display device changes key display parameters such as font size, information density, and layout configuration based on the operational mode. In display mode, it increases font size and simplifies layout for distant viewing, while in normal mode it uses standard parameters for close-up operational interaction. This parameter adaptation allows the same device to optimize for both operability and distant visibility without creating permanent complexity.
2Illumination intensity
If the display device switches between normal mode and display mode with significantly different display forms, then visibility from distant position is improved in display mode, but it creates difficulty for unfamiliar persons to confirm operation status
Solution Approach 1:
The display dynamically adapts its characteristics based on real-time detection of user distance. The system continuously monitors distance and automatically transitions between display modes, ensuring that the appropriate level of detail and visual emphasis is always provided. This eliminates the need for users to manually understand different display forms, as the system automatically presents the correct information format for the current viewing distance.
3Illumination intensity
If the display mode uses a significantly different display form from normal mode, then visibility during display mode is improved, but it requires familiarization time and reduces operational efficiency during mode switching
Solution Approach 1:
The display system dynamically transitions between modes based on detected user distance, automatically providing the optimal display form for each situation. This eliminates the need for users to learn and remember differences between static display modes, as the system adapts in real-time. The seamless dynamic transition maintains operational efficiency by preventing confusion and reducing the cognitive load associated with understanding multiple fixed display configurations.

AI summary
[Object] To provide a blood purification apparatus which can maintain operability during a normal mode and visibility during a display mode, and which can smoothly and excellently confirm an operation status in any case of the normal mode and the display mode. [Solution] The blood purification apparatus that performs blood purification treatment by purifying blood of a patient which is extracorporeally circulated includes a display device 2 which performs a display relating to the blood purification treatment. The display device 2 can switch the normal mode where an input operation relating to the blood purification treatment can be performed and a display relating to the blood purification treatment is performed and the display mode where the display relating to the blood purification treatment is exclusively performed. In the display during the display mode, a layout and a form of the display during the normal mode are maintained and enlargedly displayed.
