Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a scintillator module and silicon photomultiplier are arranged on a PCB substrate, then the detector can be miniaturized for portable devices, but the area consumption on the PCB substrate is significant and power consumption is high
Solution Approach 1:
The patent merges the scintillator module and silicon photomultiplier into a single integrated package structure, combining multiple functional components (scintillator crystal, photomultiplier, reflective casing, protective casing) into one compact unit that eliminates the need for separate PCB mounting and reduces overall area consumption
Solution Approach 2:
The patent employs a nested structure where the scintillator module is enclosed within an inner reflective casing, which is in turn enclosed within an outer protective casing. This nested arrangement maximizes space utilization and minimizes the overall footprint on the PCB substrate
2Volume of moving object
If a scintillator module and silicon photomultiplier are arranged on a PCB substrate, then the detector can be miniaturized for portable devices, but power consumption is high
Solution Approach 1:
The silicon photomultiplier is a solid-state device that inherently consumes less power compared to traditional photomultiplier tubes, and the package structure is designed to optimize its operation without requiring additional power-intensive components or cooling systems
3Volume of moving object
If a scintillator module and silicon photomultiplier are arranged on a PCB substrate, then the detector can be miniaturized for portable devices, but manufacturing costs are high
Solution Approach 1:
The manufacturing process is segmented into distinct sequential steps (attaching photomultiplier, attaching scintillator module, wire bonding, encasing in reflective resin, encasing in protective resin), allowing for standardized production techniques and reducing manufacturing complexity and cost
Solution Approach 2:
The patent uses resin materials (reflective resin with titanium dioxide, protective resin) that can be applied through standard manufacturing processes like dispensing and molding, changing the manufacturing approach from complex assembly to simpler material application processes
