Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shielded rooms for medical equipment requiring both radiation and electromagnetic shielding are operationally inefficient due to the need for two separate doors, complex construction, and spatial inefficiency, leading to increased costs and reduced patient throughput.
Innovation Solution
A single-door electromagnetic and radiation shielding system that integrates both shielding capabilities into a single enclosure, using a conductive door assembly to form a complete barrier around the room interior, allowing for quick and easy access while preventing electromagnetic and radiation leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate doors are used for radiation and electromagnetic shielding, then complete shielding is achieved, but operational efficiency decreases and patient throughput is reduced
Solution Approach 1:
The patent combines radiation shielding and electromagnetic shielding into a single integrated door assembly. The door includes both radiation shielding material (such as lead or steel) and electromagnetic shielding material (such as conductive mesh or foil), allowing one door to provide both types of protection simultaneously, thereby eliminating the need for two separate doors and improving operational efficiency.
Solution Approach 2:
The single door assembly is designed to perform multiple functions: it provides radiation shielding, electromagnetic shielding, and maintains structural integrity. By making the door multi-functional, the system achieves complete shielding while allowing faster access and improving patient throughput.
2Reliability
If two separate doors are used for radiation and electromagnetic shielding, then complete shielding is achieved, but device complexity increases
Solution Approach 1:
The patent merges the radiation shielding door and electromagnetic shielding door into a single integrated assembly. This reduces the number of components from two separate doors to one unified structure, simplifying the overall system while maintaining both shielding functions.
Solution Approach 2:
The door assembly uses composite construction, combining radiation shielding materials (such as lead, steel, or concrete) with electromagnetic shielding materials (such as conductive mesh, foil, or coated surfaces). This composite approach allows both shielding functions to be achieved within a single door structure, reducing complexity compared to having separate doors.
3Reliability
If two separate doors are used for radiation and electromagnetic shielding, then complete shielding is achieved, but construction costs and spatial requirements increase
Solution Approach 1:
The patent combines the construction of radiation shielding and electromagnetic shielding into a single door assembly manufacturing process. This reduces material costs, labor costs, and installation expenses compared to building and installing two separate doors, while still achieving complete shielding effectiveness.
Solution Approach 2:
The single door assembly is designed to fulfill multiple shielding requirements simultaneously, reducing the total quantity of shielding materials needed and simplifying the construction process. This multi-functional approach lowers both material and installation costs while maintaining effective radiation and electromagnetic protection.

Implementation Method 1
the door assembly cooperates with the single enclosure to form an electromagnetic barrier around the room interior in all directions
Implementation Method 2
a radiation shielding material, such as concrete, lead, steel or a combination thereof, is incorporated into each of the walls, ceiling and flooring of the room so as to fully enclose the room interior

AI summary
An electromagnetic and radiation shielding system includes an enclosure shaped to define a room interior which is accessible through a single passageway, and a door assembly for selectively enclosing the passageway. The door assembly includes a frame mounted within the passageway in conductive contact with a metal skin incorporated into the enclosure, a door with a conductive rear face which is adapted to selectively enclose the passageway, and a seal for selectively establishing continuous, peripheral contact between the frame and the rear face of the door when the door is disposed in its closed position. In this manner, the door assembly cooperates with the enclosure to form an electromagnetic barrier around the room interior in all directions. Additionally, both the enclosure and the door are constructed with a layer of radiation-shielding material to form a radiation barrier around the room interior in all directions.
