Solution Overview
Problem
Existing vehicles designed for assessing internal radioactive contamination are not suitable for individuals with reduced mobility or those in inaccessible locations, as they require entry into the vehicle for measurement and have limited adaptability to different morphologies.
Innovation Solution
A portable device with adjustable detectors for thyroid and thorax measurements, supported by a lightweight, modular, and easily transportable system that can be set up in any environment, allowing for adaptable positioning and reduced dimensions to accommodate various individual morphologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed vehicle-based measurement system is used, then measurement stability is improved, but accessibility for individuals with reduced mobility deteriorates
Solution Approach 1:
The support device transitions from a static vehicle-based system to a dynamic portable system with adjustable components. The support member can move along the support cross member to adjust detector positions, and the entire device can be manually transported to different locations, providing both mobility and measurement stability.
2Ease of operation
If a portable device is used, then accessibility is improved, but measurement precision deteriorates
Solution Approach 1:
The device incorporates adjustable support members that can be positioned at different locations along the support cross member. This dynamic positioning capability allows the detectors to be optimally positioned for each measurement, maintaining precision while enabling portability and adaptability to different individual morphologies.
3Adaptability or versatility
If detectors are positioned for various body types, then adaptability is improved, but device size increases
Solution Approach 1:
The support device is divided into modular components: a support cross member, multiple support feet, and movable support members carrying detectors. This segmentation allows the device to be compact when not in use while providing adaptability through the ability to position support feet at different locations and adjust support members along the cross member.
4Adaptability or versatility
If a vehicle-based system is used, then measurement coverage is improved, but transportability deteriorates
Solution Approach 1:
The system transitions from a fixed vehicle-based installation to a dynamic portable system. The support device can be manually transported to different locations and adjusted to accommodate various individual morphologies, providing both transportability and comprehensive measurement coverage through its adjustable detector positions.
