Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional application-specific control boards are designed and manufactured according to specific IoT environment requirements, then the control board can be optimized for specific devices, but the circuit needs to be redesigned or replaced every time a new IoT device is added or existing devices are upgraded
Solution Approach 1:
The control board is divided into a mainboard and detachable hardware modules. Each hardware module can be independently mounted or separated from the mainboard according to the type of IoT device to be controlled. This segmentation allows the system to maintain a standardized mainboard while adapting to different devices through module selection and combination.
Solution Approach 2:
The mainboard is designed with universal interfaces and slots that can accommodate various types of hardware modules. This universal design enables a single mainboard to support multiple IoT device types and configurations, eliminating the need to redesign the entire control board when adding new devices or upgrading existing ones.
2Ease of operation
If PLCs are programmed using ladder logic to allow easy modification when device use changes, then function extension becomes easier, but hardware configuration changes still require physical modification
Solution Approach 1:
The system enables dynamic reconfiguration of hardware modules on the mainboard without requiring physical hardware changes. The automated association mechanism dynamically links peripheral devices with application programs based on device type and position information, allowing function modification through software rather than hardware reconfiguration.
Solution Approach 2:
The system performs automated association between peripheral devices and application programs without requiring manual hardware configuration or complex programming. The management server automatically detects device types, determines appropriate application programs, and establishes associations, enabling the system to self-configure when devices are added or modified.
3Reliability
If IoT environments are continuously used without addition or modification of devices, then system stability is maintained, but the system cannot adapt to new devices or upgrades
Solution Approach 1:
The system pre-establishes the framework for device association and automation mechanisms before new devices are added. The management server is pre-configured with device type information and application program associations, enabling seamless integration of new devices without disrupting existing system stability. The automated association process is prepared in advance to handle device additions smoothly.

AI summary
Provided is an adaptive IoT service system employing a removable hardware module. The system includes a peripheral device control module, a management server, an application program configuration manager, and a user terminal. The peripheral device control module is configured such that a control board thereof for controlling a corresponding one of IoT devices is mountable to and removable from a mainboard thereof. The management server relays real-time data transmitted from IoT devices, cumulative data, and type information to the user terminal, and relays and manages the data and information. The application configuration manager automatically constructs a user interface of the user terminal on the basis of the data managed by the management server. The system constructs a user interface in real time and automatically associates the IoT device with the application program in the user terminal.
