Reflective E-Paper Display for MRI Patient Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic resonance examinations require a visual communication path for patients, but existing solutions like standard LED/LCD displays are difficult to integrate due to rigidity, electromagnetic interference, and space constraints, and are not suitable for patients with impaired hearing, while mirror systems occupy too much space.
Innovation Solution
A magnetic resonance device with a patient display unit featuring a reflective e-paper display that is flexible, energy-efficient, and integrated into the enclosure's inner wall, allowing for space-saving and interference-free visual communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a standard LED or LCD display is installed in the patient receiving area, then visual information can be provided to the patient, but the display generates electromagnetic interference leading to image artifacts
Solution Approach 1:
The patent introduces an optical intermediary system consisting of a transparent display panel and a projection system. The display panel is positioned in the patient receiving area but does not generate electromagnetic interference itself. Instead, visual information is projected onto the transparent panel, which acts as a mediator between the projection system and the patient's view, allowing visual communication without compromising image quality.
Solution Approach 2:
The patent replaces electronic displays (LED/LCD) that generate electromagnetic fields with an optical projection system combined with a transparent panel. This substitution eliminates the source of electromagnetic interference while maintaining the visual communication function. The projection system uses optical rather than electromagnetic mechanisms to deliver visual information to the patient.
2Loss of information
If a mirror system is used to project information into the patient receiving area, then visual communication is enabled, but the system occupies considerable space within the patient receiving area
Solution Approach 1:
The patent employs a thin, transparent display panel that can be integrated into the existing enclosure structure of the patient receiving area. This thin-film approach replaces the bulky mirror system, allowing visual information to be displayed without occupying significant space. The transparent nature of the panel allows it to be positioned without interfering with the patient's movement or the scanner's operation.
3Loss of information
If rigid displays are installed in the patient receiving area, then visual information can be displayed, but the displays cannot be adjusted to the curvature of the enclosure
Solution Approach 1:
The patent uses a transparent display panel that can be manufactured in curved configurations to match the enclosure's geometry. The thin-film construction allows the display to be bent and shaped without compromising its functionality, enabling seamless integration into the curved patient receiving area while maintaining visual information delivery.
4Loss of information
If standard displays are used in the patient receiving area, then visual communication is possible, but power consumption is high
Solution Approach 1:
The patent replaces power-hungry electronic displays with an optical projection system. The projection system only requires power when actively projecting information, and the transparent panel itself consumes no power. This substitution dramatically reduces the overall power consumption while maintaining the visual communication capability throughout the examination process.
