Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation detector plates face limitations in design flexibility and efficiency due to the anode and cathode being constrained to a single plane, which restricts the optimization of high voltage and ionization characteristics, and leads to inefficiencies in the use of space and increased production rejects.
Innovation Solution
The use of injection-molded carrier plates with electro-conductive applications formed in multiple planes, allowing for a scalable and precise arrangement of detector elements, including the anode and cathode, which can be designed to optimize ionization chamber dimensions and reduce production rejects through MID technology and non-cutting production methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the anode and cathode are formed in a single plane on the carrier plate, then the structure is simple and manufacturing is easier, but the design freedom and optimization of high voltage and ionization characteristics are restricted
Solution Approach 1:
The patent transitions from planar (2D) electrode arrangements to three-dimensional (3D) electrode structures extending in multiple planes. The anode and cathode are formed as electro-conductive applications in different planes on the carrier plate, enabling spatial optimization of the ionization chamber while maintaining manufacturing feasibility through injection molding processes.
2Adaptability or versatility
If the anode and cathode are formed in multiple planes, then design freedom and optimization of ionization characteristics are improved, but the device complexity increases
Solution Approach 1:
The patent combines the carrier plate and electro-conductive applications (anode and cathode) into a single integrated component manufactured through injection molding. This merging of functions reduces overall device complexity by eliminating separate assembly steps while enabling complex multi-plane electrode geometries to be formed directly during molding.
3Ease of manufacture
If the inner cavity dimensions are not precisely defined, then the production process is simpler, but the ionization chamber optimization and detection precision are reduced
Solution Approach 1:
The patent incorporates the electro-conductive applications (anode and cathode) directly into the carrier plate during the injection molding process itself, before any subsequent assembly or processing steps. This preliminary formation of precise cavity dimensions through the molding process ensures high manufacturing precision while maintaining production efficiency.
4Device complexity
If the detector elements are not arranged in a scalable configuration, then the design is simpler, but the space utilization and detection coverage are reduced
Solution Approach 1:
The patent creates a universal carrier plate design with standardized electro-conductive application patterns that can accommodate different numbers and arrangements of detector elements. The multi-plane electrode structure and precisely defined cavity dimensions enable the same basic design to be scaled for various detection requirements, from single elements to arrays, optimizing space utilization across different application scenarios.

AI summary
A detector plate includes a carrier plate, especially an injection-molded carrier plate, having a plurality of detector elements for detecting ionizing radiation. The detector elements function according to the principle of a Geiger-Müller counter. To simplify the production process and to save cost, the anode and/or the cathode should be in the form of a metallization on the carrier plate of the detector plate, the metallization(s) not being present in a single plane only. This configuration offers multiple options for designing the interior used as ionization chamber and for arranging the electrodes in this space. The options for contact with additional printed circuit boards also turn out to be highly advantageous. This further has an advantageous effect on the production process and on the qualities of the radiation measurement devices using detector plates of this kind.
