Solution Overview
Problem
Radiometric measuring devices face challenges in securely and practically arranging scintillators within housings due to mechanical damage, moisture exposure, and ambient light sensitivity, while ensuring explosion protection and stability during vibrations.
Innovation Solution
A radiometric measuring device design featuring a scintillator held by a u-shaped plastic holding element with resilient support wings, which centers and stabilizes the scintillator within the housing, and includes a restoring element for maintaining optical contact with the light detector, accommodating various scintillator cross-sections and compensating for manufacturing tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the scintillator is securely fixed in the housing to protect from mechanical damage and moisture, then the reliability is improved, but the device complexity increases due to the need for additional holding elements and sealing structures
Solution Approach 1:
The holding element is inserted into the housing through an opening, creating a nested structure where the holding element is contained within the housing. This allows the scintillator to be securely held while maintaining a compact overall structure and avoiding the need for complex internal mounting brackets or external fastening mechanisms.
Solution Approach 2:
The housing is divided into functional zones: a first housing part containing the scintillator and holding element, and a second housing part containing the light detector, separated by an optically transparent element. This segmentation allows each component to be optimized and protected independently while maintaining overall system reliability.
2Reliability
If the scintillator is protected from ambient light and moisture through sealed housing, then the reliability is improved, but the manufacturing cost increases due to additional sealing requirements
Solution Approach 1:
The holding element is inserted into the housing through an opening without requiring complex gaskets or sealing flanges. The simple nested insertion design minimizes sealing surfaces and reduces manufacturing complexity while still providing adequate protection against moisture and ambient light.
3Reliability
If the holding element centers the scintillator in the housing to prevent contact with housing walls during vibrations, then the reliability is improved, but the device complexity increases due to additional centring mechanisms
Solution Approach 1:
The holding element features an asymmetric U-shaped cross-section with a specific orientation that naturally centers the scintillator within the housing. The asymmetric geometry provides stable positioning and prevents contact with housing walls during vibrations without requiring additional symmetric support structures or adjustment mechanisms.
Solution Approach 2:
The holding element has a curved bottom surface that conforms to the shape of the scintillator, providing stable centring and support. The curved geometry naturally guides the scintillator into the correct position and maintains stability during vibrations without requiring flat surfaces or complex positioning features.
4Adaptability or versatility
If the holding element is designed to accommodate various scintillator cross-sections, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The holding element is designed with a universal U-shaped holding region that can accommodate scintillators with different cross-sections (round, square, rectangular). The generic U-shaped geometry provides sufficient support and centring for various scintillator shapes without requiring custom-designed holding features for each scintillator type, thereby reducing manufacturing precision requirements.
