Dual Wireless Links in Radiation Irradiation Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation irradiation devices face challenges in smoothly performing wireless communication with external devices due to the need for a single wireless communication system, which cannot accommodate the varying performance requirements for different types of data such as operation instructions and image information.
Innovation Solution
The device employs two distinct wireless communication units: a first unit for operation instructions with faster response speed and lower power consumption, and a second unit for image data with higher communication speed, using different communication systems to ensure seamless communication for both types of information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single wireless communication system is used for both operation instructions and image data, then device complexity is reduced, but communication performance deteriorates because the system cannot simultaneously satisfy the different requirements (response speed, communication speed, power consumption) of the two types of data
Solution Approach 1:
The wireless communication system is segmented into two independent communication units: a first wireless communication unit for transmitting operation instructions with fast response speed and low power consumption, and a second wireless communication unit for transmitting image data with high communication speed. Each unit is optimized for its specific communication requirements, resolving the contradiction between system simplicity and communication performance.
2Reliability
If the first wireless communication unit uses faster response speed for operation instructions, then operational reliability improves, but power consumption increases
Solution Approach 1:
Different communication units are assigned different performance characteristics according to their specific needs: the first wireless communication unit is designed with fast response speed and low power consumption for operation instructions, while the second wireless communication unit is designed with high communication speed for image data. This local optimization resolves the contradiction between response speed and power consumption.
3Productivity
If the second wireless communication unit achieves higher communication speed for image data, then data transmission efficiency improves, but reachable distance of radio waves decreases
Solution Approach 1:
The communication system is divided into two specialized units: the first unit handles operation instructions with focus on response speed and power efficiency, while the second unit handles image data with focus on communication speed. This segmentation allows each unit to be optimized for its specific function without compromising overall system performance.
