Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth or wireless LAN communication is used for data exchange between electronic musical instrument and terminal, then data communication capability is improved, but connection process complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing NFC communication links before the actual data transfer. The NFC connection is set up in advance as a quick-connect mechanism, allowing Bluetooth or wireless LAN to immediately resume data transmission without going through complex connection procedures. This preliminary NFC link establishment simplifies the overall connection process while maintaining reliable data communication capability.
Solution Approach 2:
The patent uses NFC communication as an intermediary mechanism between the terminal and electronic musical instrument. The NFC serves as a mediator that facilitates the initial connection and data exchange, enabling the main Bluetooth or wireless LAN communication to function efficiently. This intermediary approach resolves the contradiction by using a simple NFC layer to manage the complexity of the underlying Bluetooth/wireless LAN connection processes.
2Ease of operation
If NFC communication is used for quick connection, then ease of operation is improved, but data transmission speed is reduced
Solution Approach 1:
The patent segments the communication process into two distinct phases: connection establishment and data transmission. NFC communication handles the connection establishment phase, providing quick and easy pairing. Once connected, the system switches to Bluetooth or wireless LAN for the data transmission phase, ensuring high-speed communication. This segmentation allows each communication technology to operate in its optimal performance range, resolving the contradiction between ease of operation and transmission speed.
Solution Approach 2:
The patent implements a dynamic communication architecture that automatically switches between different communication technologies based on the operational phase. The system dynamically transitions from NFC (for connection) to Bluetooth/wireless LAN (for data transfer). This dynamic adaptation allows the system to optimize for ease of operation during connection and for speed during data transmission, eliminating the need to choose one fixed mode.
3Reliability
If repeated reading and writing operations are performed via NFC, then data exchange completeness is improved, but communication time increases
Solution Approach 1:
The patent maintains continuous useful action by implementing repeated reading and writing operations over the NFC connection. Rather than attempting to transfer all data in a single operation, the system continuously exchanges data packets through multiple read-write cycles. This continuous operation ensures that all necessary performance information and apparatus settings are completely transferred, improving data exchange completeness while managing the total communication time through efficient packetization.
Solution Approach 2:
The patent applies periodic action by structuring the NFC data exchange as a series of periodic read-write operations. The system performs reading and writing at regular intervals, systematically transferring data in manageable chunks. This periodic approach ensures complete data exchange by methodically covering all data elements while optimizing the timing and frequency of operations to minimize total communication time.

AI summary
An electronic musical instrument includes a communication unit and a processing unit. The communication unit is capable of performing short-range wireless communication with a terminal. In a case where the terminal performs an operation according to an operation pattern including an operation of repeating, in a predetermined pattern, at least one of transmission of a reading request of data and transmission of writing target data and a writing request for the writing target data while the electronic musical instrument and the terminal are in a state in which the short-range wireless communication is possible, the processing unit performs a process of transmitting corresponding data when the reading request is received using the communication unit, and performs a process of writing the writing target data when the writing target data and the writing request for the writing target data are received via the communication unit.
