Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent power supply units are used to meet diverse voltage requirements, then the voltage requirements of different components can be satisfied, but the system complexity and size increase
Solution Approach 1:
The patent merges multiple independent power supply units into a single integrated power management module that provides multiple voltage outputs (e.g., 3.3V for laser emitter, 3.6V for detection array, 18V-20V for avalanche diodes) through voltage conversion and regulation circuits. This consolidation reduces the number of separate power supply components while maintaining the ability to satisfy diverse voltage requirements of different detection system components.
Solution Approach 2:
The power management module is designed with multi-functionality to serve multiple purposes: it acts as a voltage converter, regulator, and distributor for different components simultaneously. The module includes voltage conversion circuits that can generate multiple voltage levels from a single input, making it a universal power solution that eliminates the need for separate specialized power supplies for each component.
2Adaptability or versatility
If multiple independent power supply units are used to meet diverse voltage requirements, then the voltage requirements of different components can be satisfied, but the chip miniaturization and integration are hindered
Solution Approach 1:
The patent consolidates multiple power supply units into a single compact power management module, significantly reducing the overall volume occupied by power supply components. This integration enables the system to meet chip miniaturization requirements while still providing multiple voltage outputs for different components through integrated voltage conversion and regulation circuits.
Solution Approach 2:
The power management module employs a nested architecture where voltage conversion circuits, regulation circuits, and distribution circuits are integrated within a compact structure. The module is designed to be nested within or integrated with the detection system chip, allowing multiple power functions to occupy minimal space through hierarchical integration.
3Device complexity
If a single power supply voltage is used for all components, then the system is simplified, but the precision requirements and reliable operation of components with different voltage needs cannot be met
Solution Approach 1:
The power management module implements local quality by providing different voltage levels to different components according to their specific requirements. The module includes dedicated voltage conversion and regulation circuits that ensure each component receives its required voltage (3.3V for laser emitter, 3.6V for detection array, 18V-20V for avalanche diodes), thereby maintaining reliable operation while keeping the overall system design relatively simple.
