Dual-Frequency Wireless Image Transfer for Medical Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless image transfer systems using high-frequency bands like 60 GHz suffer from reduced receiver sensitivity due to strong radio wave straightness, leading to potential data loss and interference issues in medical environments, especially when operators or obstacles move.
Innovation Solution
A dual-frequency wireless image transfer system that dynamically switches between 60 GHz and 5 GHz bands based on reception state, using a control unit to select the best image quality from both bands, ensuring stable and high-quality image transfer by categorizing reception states as good, bad, or intermediate and adjusting communication modes accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a high-directivity antenna is adopted in a wireless device using a 60 GHz band radio wave, then the radio wave straightness is improved, but receiver sensitivity is degraded
Solution Approach 1:
The system dynamically changes the frequency band parameter between 60 GHz and 5 GHz based on reception state. When reception quality deteriorates, it switches from 60 GHz to 5 GHz band, thereby changing the operating parameters to maintain reliable image transfer despite the limitations of high-directivity antennas at 60 GHz
2Object-affected harmful factors
If wireless transfer with a 60 GHz band is adopted, then interference influence is reduced, but data loss occurs due to degraded receiver sensitivity
Solution Approach 1:
The system implements feedback mechanism by monitoring reception state (RSSI, SNR, error rate) and using this information to dynamically switch between 60 GHz and 5 GHz bands. This feedback loop prevents data loss by detecting degradation early and switching to a more reliable band before significant data loss occurs
Solution Approach 2:
The system changes the frequency band parameter from 60 GHz to 5 GHz when reception conditions deteriorate, thereby adapting to maintain reliable data transfer and prevent forward data loss while minimizing interference influence
3Device complexity
If a single frequency band is used for wireless image transfer, then device complexity is reduced, but reception stability deteriorates when operators or obstacles move
Solution Approach 1:
The wireless communication device is designed with multi-functionality by incorporating both 60 GHz and 5 GHz band communication capabilities. This allows the single device to adapt to different reception conditions by switching between bands, thereby maintaining reception stability without requiring multiple separate devices
Solution Approach 2:
The system implements dynamic band switching based on real-time reception state monitoring. The communication frequency band is not fixed but dynamically adjusted between 60 GHz and 5 GHz according to RSSI, SNR, and error rate measurements, thereby maintaining reception stability in dynamic environments where operators or obstacles may move

AI summary
A wireless image transfer system includes an image quality judgement unit configured to judge reception states of a first image transmitted in a first frequency band by a first image wireless block and a second image transmitted in a second frequency band by a second image wireless block and image qualities of the received images; and a second control unit configured to sort the reception states into a good state, a bad state, and an intermediate state, select a first image signal in the good state, steadily operate the second image wireless block and periodically operate the first image wireless block in the bad state, and select an image with a better quality from the first image signal and a second image signal and output the selected image in the intermediate state.
