Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dose measuring devices are unsuitable for determining the radiation dose applied to particulate material, particularly in industrial applications, as they fail to accurately measure radiation exposure in free-falling materials and are not designed for large quantities.
Innovation Solution
A dose measuring device comprising a radiation-sensitive measuring film wound onto a base body with a density matching the particulate material, allowing precise measurement of radiation dose throughout the material stream, with a base body made from a carbon-based material and guide sections for accurate film positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional dose measuring devices are used, then radiation dose can be measured in simple applications, but they are unsuitable for determining radiation dose applied to particulate material in industrial applications
Solution Approach 1:
The patent changes the physical parameters of the measuring device by matching the density of the base body to the density of the particulate material being measured. This allows the measuring device to flow with the material stream and accurately measure radiation dose at different positions within the material, resolving the contradiction between adaptability to particulate material and measurement precision.
2Quantity of substance
If a removable dosimeter is arranged centrally in a container, then radiation introduced in the centre can be measured, but it is unsuitable for determining radiation dose applied to large quantities of particulate material
Solution Approach 1:
The patent segments the measuring approach by using multiple dose measuring devices distributed throughout the particulate material rather than a single central device. This allows measurement of radiation dose across the entire material stream, enabling the system to handle large quantities of particulate material in industrial applications.
Solution Approach 2:
The base body acts as an intermediary that facilitates the integration of the measuring film with the particulate material stream. By matching densities, the base body enables the measuring device to flow with the material and measure radiation dose throughout the entire quantity of material being treated.
3Reliability
If the radiation dose is increased to ensure sufficient pasteurization and sterilization, then micro-organisms can be killed effectively, but the particulate material may undergo damage
Solution Approach 1:
The patent implements feedback by using the dose measuring device to monitor the actual radiation dose applied to the particulate material. This information can be used to control and optimize the radiation treatment process, ensuring sufficient pasteurization and sterilization while preventing excessive radiation that would cause material damage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise determination of radiation dose applied to particulate material during pasteurization and sterilization, ensuring effective treatment without material damage, and allowing for higher throughput in industrial applications.
Implementation Method 1
the radiation-sensitive layer changes colour. The value of the applied radiation dose can be determined from the degree of discolouration
Implementation Method 2
The radiation dose applied to the particulate material by means of the electron beam must be sufficiently high that a sufficient pasteurization and/or sterilization of the treated material is ensured
