Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high communication speed is used for data transmission, then data transmission efficiency is improved, but communication reliability during connection processes deteriorates
Solution Approach 1:
The communication device dynamically adjusts communication speed based on the operation phase: using a first (lower) communication speed during connection processes and a second (higher) communication speed during data transmission. This dynamic adjustment resolves the contradiction by matching communication speed to the specific operational requirements of each phase.
Solution Approach 2:
The invention changes the communication speed parameter according to the operational context. By setting different speed parameters for connection processes versus data transmission, the system optimizes both reliability during connection and efficiency during data transfer, eliminating the need to choose between the two conflicting requirements.
2Reliability
If a low communication speed is used during connection processes, then communication reliability is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The communication device transitions from a static communication speed to a dynamic one, switching between first communication speed (for connection) and second communication speed (for data transmission). This dynamic behavior allows the system to achieve high reliability during connection while maintaining high efficiency during data transfer.
Solution Approach 2:
By changing the communication speed parameter based on operational phase, the system resolves the contradiction between reliability and efficiency. The parameter change ensures that each phase operates at the optimal speed for its specific requirements.
3Device complexity
If a single communication speed is used for both connection and data transmission, then device complexity is reduced, but overall communication performance deteriorates
Solution Approach 1:
The invention implements dynamic communication speed adjustment with automatic switching between first and second communication speeds based on operational phase. This dynamic approach maintains relatively simple device architecture while significantly improving overall communication performance by optimizing speed for each phase.

AI summary
A monitoring device is configured to monitor a state of a battery and transmitting the state of the battery as battery information to a control device by wireless communication. The monitoring device includes a monitoring-device-side communication unit configured to execute a connection process with a control-device-side communication unit and communicate the battery information. The monitoring-device-side communication unit is configured to set a communication speed when at least a part of a predetermined connection process of the connection process is executed with the control-device-side communication unit to be lower than a communication speed when the battery information is transmitted to the control-device-side communication unit.
