Solution Overview

Problem

Existing radiation detectors face instability and security issues in wireless communication when transmitting radiation images, particularly when operating as a master or slave in wireless communication networks.

Innovation Solution

The radiation detector operates as a master in wireless communication, preventing direct connection to the global network and employs power consumption reduction modes to ensure stable and secure transmission of radiation images, with the communication unit functioning as an access point.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the radiation detector operates as a master in wireless communication, then communication stability is improved, but security is worsened due to direct global network connection

Engineering Contradiction:

Improvecommunication stabilityVSAvoidsecurity risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a local network as an intermediary between the radiation detector (master) and the global network. The master performs wireless communication with slave devices through this local network buffer, preventing direct connection to the global network while maintaining communication stability. This mediator architecture isolates the medical device from direct internet exposure, reducing security risks.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the communication unit operates continuously to ensure stable transmission, then communication reliability is improved, but power consumption increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic communication cycles where the master alternates between active transmission periods and sleep periods. During sleep periods, the communication unit reduces power consumption by entering a low-power state. The system wakes up at scheduled intervals to transmit radiation images and then returns to sleep, achieving reliable periodic communication while significantly reducing overall power consumption compared to continuous operation.

Inventive Principle:

Principle #19Periodic action
