Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If workers use manual cleaning with radioactive wash and sponge, then cleanup can be performed, but the process is labor-intensive and potentially harmful to workers
Solution Approach 1:
The patent replaces the manual mechanical cleaning system (workers using sponges and radioactive wash) with an automated vacuum system that uses electrical power to create suction. The vacuum cleaner automatically collects radioactive materials through suction and stores them in a sealed container, eliminating the need for workers to manually handle radioactive contaminants while significantly improving cleanup efficiency
Solution Approach 2:
The patent introduces a vacuum cleaner as an intermediary device between the radioactive contamination and the worker. This intermediary system performs the hazardous cleaning function remotely, with the radioactive materials being collected and stored in a sealed container within the vacuum cleaner, preventing direct exposure to workers while maintaining effective cleanup capability
2Productivity
If a vacuum cleaner is used for radioactive cleanup, then cleanup efficiency is improved, but the device must handle both wet and dry materials safely
Solution Approach 1:
The patent designs the vacuum cleaner with universal functionality to handle both wet and dry radioactive materials. The system incorporates a HEPA filter that effectively captures particulates from both material types, a sealed collection container that prevents contamination regardless of material state, and a design that accommodates various cleaning scenarios in radioactive environments, making the device adaptable to diverse cleanup requirements
3Reliability
If radioactive material is collected in a disposable container, then safety is improved, but the container must be integrated within the vacuum system
Solution Approach 1:
The patent implements a nested structure where the disposable container is placed inside the vacuum cleaner housing. The container is positioned within the collection chamber, and the entire assembly is integrated with the filtration and sealing systems. This nested arrangement allows the disposable container to be easily inserted and removed while maintaining a compact, integrated system that ensures safe containment without excessive complexity

AI summary
A system and method of clearing radioactive contamination from a surface is provided by means of a handheld device and a method of using the handheld device. The handheld device has a manual system which operates by pressing a button to spray radioactive wash on the surface. The handheld device also has an electrical system which operates by pressing a button to suction radioactive contamination from the surface. The function of this system is to clean the surface from radioactive contamination. The system of the handheld device consists of a suctioning part and a pump and functions by suctioning the radioactive contamination into a lead cylinder, from which it is easily disposed. A third component includes a gauge for detecting contamination before, during, and after the cleaning and suctioning processes of the handheld device.
