Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing local dosimeter devices are costly, difficult to use, and prone to measurement errors, particularly in settings like doctor's offices with X-ray machines, where they require frequent replacement and handling by non-technical personnel, leading to potential inaccuracies and complications in dose determination.
Innovation Solution
A local dosimeter device with at least two scattering body assemblies, featuring an alignment device for simplified assembly and a quick-connection mechanism for rapid assembly and replacement, made from cost-effective materials like polyamide, which also includes a shape-complementary and sealing design to enhance handling and measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If local dosimeter devices use complex assembly structures to ensure measurement accuracy, then measurement precision is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The scattering body is divided into multiple scattering body assemblies that can be separately manufactured and then combined. Each assembly contains specific structural features (protrusions, recesses, alignment marks) that enable precise positioning when assembled, maintaining measurement accuracy while simplifying handling and replacement procedures
2Measurement precision
If local dosimeter devices use precise alignment mechanisms to avoid measurement errors, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The scattering body assemblies incorporate asymmetric alignment features such as protrusions fitting into recesses, and specific alignment marks with defined geometries. These asymmetric features provide unambiguous orientation and precise positioning when assemblies are combined, ensuring measurement accuracy without requiring complex active alignment mechanisms
3Productivity
If local dosimeter devices require frequent replacement of measurement components, then productivity is improved (faster dose determination), but loss of time increases (assembly and replacement time)
Solution Approach 1:
The dosimeter is designed with modular scattering body assemblies that can be independently replaced. The simple connection mechanism allows rapid assembly and disassembly, enabling frequent replacement of measurement components without significant time loss, thus maintaining high productivity in dose determination
Solution Approach 2:
Multiple scattering body assemblies can be pre-prepared with different configurations or measurement media. When one assembly needs replacement, a pre-prepared assembly can be immediately substituted, minimizing replacement time and maintaining continuous productivity in radiation monitoring
