Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each service object is provided with a set of computing platform, then the adaptability to different application scenarios is improved, but the cost and system complexity increase greatly
Solution Approach 1:
The patent implements a universal remote reconfiguration system where a single computing platform can serve multiple service objects through dynamic functional reconfiguration. The system uses a centralized configuration server that can remotely reconfigure the same hardware platform to perform different sensing and processing functions, eliminating the need for separate computing platforms for each service object while maintaining full adaptability to various application scenarios.
Solution Approach 2:
The system employs dynamic reconfiguration capabilities where the computing platform's functional architecture can be changed in real-time based on service requirements. The reconfiguration server receives service object information, determines appropriate configuration schemes, and dynamically adjusts the platform's hardware logic and software environment to match different application needs, enabling one platform to adapt to multiple scenarios without physical changes.
2Adaptability or versatility
If remote reconfiguration capability is added to IoT terminals, then the versatility and adaptability are improved, but the device complexity increases
Solution Approach 1:
The patent extracts the complex reconfiguration control logic from the IoT terminal itself and places it in an external reconfiguration server. The terminal only retains minimal local configuration capabilities, while the server handles the sophisticated tasks of receiving service information, determining configuration schemes, and generating reconfiguration instructions. This separation reduces terminal complexity while preserving versatility.
Solution Approach 2:
The system introduces a reconfiguration server as an intermediary between service objects and IoT terminals. This mediator receives service requirements, processes them through a determination module that selects appropriate configuration schemes from a library, and translates them into terminal-specific reconfiguration instructions. The intermediary handles the complexity of adaptation logic externally, keeping the terminal itself relatively simple.

AI summary
A remote reconfiguration system for an Internet of Things (IoT) intelligent sensing terminal includes: a controlled terminal with a field programmable gate array (FPGA); and a remote control unit connected to the controlled terminal and a control device; where the remote control unit is configured to receive control information sent by the control device, process the control information and send the processed control information to the FPGA, such that the FPGA performs remote local autonomous reconfiguration based on the preprocessed control information. The system resolves problems that a traditional IoT terminal cannot realize remote control and cannot follow functional requirements to perform local autonomous reconfiguration, and has better versatility and expandability.
