Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical examination rooms, preventing interference between apparatuses with restricted and movable operating areas is challenging due to reliance on operator sensory perception, which can lead to accidents involving patients and staff.
Innovation Solution
A medical information processing system using optical cameras to construct 3D space coordinates, determine stationary device operating areas, identify positional coordinates of obstacles, and report detection results if obstacles are within these areas, thereby alerting personnel to potential interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operator sensory perception and experience are used to avoid interference, then the system remains simple and inexpensive, but the reliability of preventing accidental contact deteriorates
Solution Approach 1:
The patent replaces the mechanical reliance on operator sensory perception with an optical detection system using cameras and image processing. The system captures images of the examination room, automatically identifies apparatus positions and operating areas, and provides visual warnings to prevent interference, thereby substituting human sensory limitations with automated optical detection.
Solution Approach 2:
The patent introduces an intermediary monitoring system that acts as a mediator between the operator and the apparatuses. This system includes image capture devices, processing units that determine operating areas, and warning output devices that provide visual feedback, serving as an intermediate layer to enhance safety without requiring direct operator judgment.
2Reliability
If automated monitoring system is implemented to prevent interference, then the reliability of preventing accidental contact improves, but the device complexity increases
Solution Approach 1:
The patent implements a multi-functional system where the image processing apparatus performs multiple tasks: capturing room images, identifying apparatus positions, determining operating areas, detecting potential interference, and providing warnings. This universal approach consolidates multiple safety functions into a single integrated system, managing complexity through functional consolidation rather than proliferation of separate devices.
Solution Approach 2:
The system enables self-monitoring and self-warning capabilities within the examination room. The image processing apparatus automatically detects apparatus positions and operating areas without external intervention, and generates warnings autonomously when potential interference is detected, allowing the system to serve its own safety monitoring function without requiring additional external monitoring equipment.
3Productivity
If real-time detection and warning system is used, then the productivity of medical procedures is maintained, but the device complexity increases
Solution Approach 1:
The patent ensures continuous monitoring and warning capability throughout the medical procedure. The image processing apparatus continuously captures images, tracks apparatus positions, and maintains awareness of operating areas without interruption, providing uninterrupted safety monitoring that allows medical procedures to proceed efficiently without delays caused by safety concerns.

AI summary
A medical information processing apparatus includes a processing circuit. The processing circuit is configured to: determine an operating area relating to a device having a predetermined movable range, identify positional coordinates corresponding to the operating area in an examination room and positional coordinates of an obstacle in the examination room, based on a camera image taken by an optical camera installed in the examination room; and report a detection result if the positional coordinates of the obstacle are included in the positional coordinates of the operating area.
