Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a custom single-use interface is designed for each subsystem, then the interface can be tailored to specific subsystem requirements, but the design process becomes repetitive and resource-intensive when additional components are added
Solution Approach 1:
The patent implements a universal interface board that can connect to multiple different subsystems through a standardized mechanical and electrical interface. The board includes a controller that can be configured to work with various RF/microwave subsystems, eliminating the need to design custom interfaces for each subsystem. This universal approach allows the same hardware platform to serve multiple functions across different applications.
Solution Approach 2:
The interface board incorporates a reconfigurable controller that can dynamically adapt its behavior based on the connected subsystem. The controller can be programmed or configured to recognize and work with different subsystem types, allowing the interface to change its operational characteristics without physical redesign. This dynamic adaptability enables the same hardware to serve multiple subsystem configurations.
2Adaptability or versatility
If a Raspberry Pi is used as the controller, then general application capabilities are provided, but real-time control is difficult due to slow processing speed and limited hardware functionality
Solution Approach 1:
The patent specifies using a microcontroller or microprocessor with real-time operating system instead of a general-purpose Raspberry Pi. This changes the key parameter of processing speed and determinism, enabling real-time control while maintaining programmability. The controller can be selected based on specific real-time requirements, with options ranging from high-speed microcontrollers to real-time operating systems that guarantee timely response to control signals.
3Ease of manufacture
If custom PCBs with pins are used to feed signals, then direct connections are provided, but power supply and monitoring capabilities are not included
Solution Approach 1:
The patent integrates multiple functions into a single interface board, including signal routing, power supply, and monitoring capabilities. The board combines the connector functions with voltage regulation, power distribution, and monitoring circuits all in one unified platform. This merging eliminates the need for separate power supply and monitoring systems, providing a comprehensive interface solution.
4Adaptability or versatility
If components are replaced on the subsystem, then functionality can be updated, but desoldering and resoldering connections is inefficient
Solution Approach 1:
The patent implements a modular design where the interface board is a separate, removable component from the subsystem. Components on the interface board can be replaced or reconfigured without affecting the subsystem itself. The standardized mechanical interface allows the board to be detached and reattached easily, enabling component replacement without desoldering operations on the subsystem.
