Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional radiation detectors use a heavy metal structure with lead layers to reduce ambient radiation background, then measurement precision is improved, but weight increases significantly (exceeding 500 kg)
Solution Approach 1:
The detector is divided into multiple independent detection modules that can be separated and transported individually. Each module contains its own sensor elements and can function independently or be combined with other modules, transforming a single 500+ kg unit into manageable segments that are much lighter and easier to move.
Solution Approach 2:
The lead layers and heavy metal shielding structures are removed or significantly reduced from the detector design. The patent achieves radiation background reduction through alternative means such as electronic filtering and sensor placement strategies rather than relying on heavy physical shielding.
2Stability of the object's composition
If traditional radiation detectors are installed as fixed single-block structures with numerous permanently fastened elements, then structural stability is improved, but ease of installation and relocation deteriorates
Solution Approach 1:
The detector structure is segmented into modular units connected by reversible fastening mechanisms. This allows the detector to be assembled from separate modules during installation and disassembled for relocation, eliminating the need for permanent fixation while maintaining structural integrity during operation.
Solution Approach 2:
The detector transitions from a static fixed installation to a dynamic reconfigurable structure. The reversible fastening system enables the detector to be easily assembled, disassembled, and repositioned, transforming it from an immobile structure into a mobile system that can be adapted to different locations and configurations.
3Measurement precision
If traditional radiation detectors use up to a hundred sensors arranged in complex configurations surrounding the body, then measurement precision is improved, but device complexity increases significantly
Solution Approach 1:
The complex array of up to a hundred sensors is divided into multiple detection modules, each containing a smaller number of sensor elements. This segmentation simplifies the overall system architecture by breaking down the complex sensor array into manageable units with fewer interconnections and simpler electrical pathways.
Solution Approach 2:
The detection modules are designed to be universal and interchangeable, with each module capable of performing the same detection function. This standardization reduces complexity by eliminating the need for unique wiring and control circuits for each individual sensor, as modules can be freely swapped and reconfigured.
4Measurement precision
If traditional radiation detectors require multiple specialized personnel to operate and guide the measurement procedure, then measurement precision is improved through expert oversight, but ease of operation deteriorates
Solution Approach 1:
The detector is equipped with automated measurement procedures and guidance systems that enable single-operator independent use. The system automatically guides the measurement process, processes data, and generates results without requiring specialized personnel to manually guide each step, making the device self-sufficient and easy to operate.
Solution Approach 2:
The detector incorporates advanced electronic processing and automated control systems that accelerate and simplify the measurement procedure. The automated data processing and analysis capabilities replace the need for expert human intervention in interpreting results, enabling rapid and accurate detection by untrained operators.
