Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual transfer of radioactive materials is performed by operators, then the transfer process is simple and direct, but operators suffer high radiation exposure and health damage
Solution Approach 1:
The patent introduces a transfer device as an intermediary mechanism between the first radiation shielding device and the second radiation shielding device. This transfer device automatically transports radioactive materials without requiring operators to manually handle the materials, thereby eliminating direct radiation exposure to operators while maintaining efficient transfer operations
Solution Approach 2:
The patent replaces the manual mechanical operation of operators with an automated transfer device system. The transfer device uses mechanical automation to perform the transfer task, substituting human operators who would otherwise be directly exposed to radiation during the transfer process
2Productivity
If operators work in close range without adequate protective measures, then the transfer process is quick and direct, but operators receive high radiation doses
Solution Approach 1:
The transfer device serves as an intermediary that enables rapid transfer of radioactive materials without requiring operators to be in close proximity. The automated system maintains speed efficiency while eliminating the need for operators to work in high-radiation zones
Solution Approach 2:
The patent divides the transfer system into distinct components: the first radiation shielding device, the transfer device, and the second radiation shielding device. This segmentation allows the transfer process to be automated and separated from operator presence, maintaining productivity while protecting operators from radiation exposure

AI summary
The present application relates to a radioactive material transfer system and transfer method. The radioactive material transfer system includes: a first radiation shielding device at least configured to accommodate a radioactive material; a second radiation shielding device at least configured to store the radioactive material; and a transfer device configured to transfer the radioactive material located in the first radiation shielding device into the second radiation shielding device. By transferring the radioactive material from the first radiation shielding device to the second radiation shielding device by the transfer device for storage, the personnel are protected from radiation contamination, thereby improving the safety of transfer operations.
