Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation image capturing systems face challenges with cable obstructions in operating rooms, increased size and weight due to battery requirements for wireless communication, and the need for frequent battery charging, which disrupts wireless communication.
Innovation Solution
A bed-based radiation image capturing system that eliminates cables between the bed and external devices by using wired communications for the radiation detecting cassette and wireless communications for the bed and console, with a battery-powered transmission and reception processor that minimizes cable length and reduces electromagnetic interference, and includes a control processor for compressing data to enhance transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable is connected to the radiation detector for data transmission and power supply, then reliable data transmission is achieved, but the cable presents obstacles to surgeons and assistants in the operating room and may be imaged in the radiation image
Solution Approach 1:
The patent extracts the power supply function from the cable connection by introducing a battery into the radiation detector. This separates the data transmission function (which remains wired) from the power supply function (which becomes wireless via battery), thereby removing the cable obstruction problem while maintaining reliable data transmission.
Solution Approach 2:
The patent introduces a wireless communication module as an intermediary between the radiation detector and external devices. This module enables wireless data transmission, completely eliminating the need for cables and their associated obstructions in the operating room environment.
2Ease of operation
If wireless communication is used to eliminate cables, then operating room accessibility is improved, but the radiation detector requires a battery and memory which increase its size and weight
Solution Approach 1:
The patent makes the wireless communication capability dynamic by providing a switchable connection between wired and wireless modes. The system can adapt between wireless operation (with battery) and wired operation (without battery), allowing the radiation detector's configuration to change based on operational requirements, thereby managing weight implications flexibly.
3Ease of operation
If wireless communication is implemented, then cable obstructions are eliminated, but the radiation detector requires a battery which needs frequent charging and disrupts wireless communication
Solution Approach 1:
The patent implements dynamic adaptability by allowing the radiation detector to switch between wireless and wired communication modes. When battery charging is required, the system can transition to wired mode, eliminating the disruption to communication and ensuring continuous operational capability without time loss.
4Ease of operation
If a cable is gripped by a gripper to prevent obstructions, then cable positioning is improved, but surgeons and staff must be fully aware of the cable's existence
Solution Approach 1:
The patent extracts the power supply function from the cable system and relocates it to a battery within the radiation detector. This eliminates the need for cable management mechanisms like grippers and removes the cable entirely from the operating environment, thereby eliminating both the positioning issue and the awareness burden on surgical staff.

Data Source
AI summary
A radiation detecting cassette is disposed in a desired position between a bed and a patient in an operating room. After a detector-side connector and a bed-side connector are connected to each other by a cable, an image capturing apparatus captures and records radiation image information of the patient in a radiation detector. The recorded radiation image information is transmitted from a transceiver of the bed to a console by way of wireless communications, then processed by the console, and transmitted to a display device, which displays a radiation image based on the supplied radiation image information.
