Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable is connected to the radiation detector for transmitting data and power, 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 the external device. This wireless module mediates the power and data transmission, eliminating the need for a physical cable connection and thus removing obstacles for surgical staff while maintaining communication reliability.
2Ease of operation
If a wireless communication module with battery is installed in the radiation detector, then cable obstructions are eliminated, but the radiation detector increases in size and weight
Solution Approach 1:
The patent extracts only the essential wireless communication functionality from a full wireless system, implementing a minimal wireless communication module that provides necessary power and data transmission without requiring large battery capacity or complex wireless infrastructure, thus minimizing the increase in size and weight.
3Ease of operation
If a battery is installed in the radiation detector for wireless communication, then cable connections are eliminated, but the radiation detector requires frequent charging which disrupts wireless communication
Solution Approach 1:
The patent applies preliminary action by providing a battery with sufficient capacity that is pre-charged before use, allowing the radiation detector to operate throughout the entire surgical procedure without requiring charging interruptions. The battery is designed to last through the complete operation, eliminating time loss from charging cycles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a clear working environment by eliminating cable obstructions, reducing the size and weight of radiation detectors, and enabling efficient wireless data transmission with minimized noise susceptibility and reduced electromagnetic interference.
Implementation Method 1
a radiation detector having a solid-state detector for converting a radiation directly into an electric signal or converting a radiation into visible light with a scintillator and then converting the visible light into an electric signal
Implementation Method 2
a transmission and reception processor for transmitting radiation image information from the bed to the console by way of wireless communications
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.
