Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired transmission method is used for updating parameters or firmware, then data transmission reliability is improved, but operation complexity and time consumption increase
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The updating device and target device establish wireless communication channels to transmit updating information, eliminating the need for physical cable connections while maintaining data transmission reliability through protocol-level error handling and verification mechanisms.
Solution Approach 2:
The patent introduces a wireless communication protocol as an intermediary layer between the updating device and target device. This protocol manages the data transmission process, ensuring reliable delivery through acknowledgment mechanisms, error detection, and automatic retry logic, thereby maintaining reliability without requiring physical connection.
2Stability of the object's composition
If wired transmission method is used for updating parameters or firmware, then data transmission stability is improved, but updating time and operational efficiency deteriorate
Solution Approach 1:
The patent implements preliminary actions by establishing wireless communication channels and performing device discovery and authentication before the actual data transmission begins. This preparation phase ensures stable connection setup, allowing the subsequent firmware or parameter updating to proceed efficiently without interruptions or reconnection delays.
Solution Approach 2:
By replacing the mechanical wired connection with wireless communication, the system eliminates the time required for physical plug-and-play operations. The wireless system establishes connections through automated protocol handshakes, significantly reducing the time needed to initiate and complete the updating process while maintaining transmission stability.
3Ease of operation
If wireless transmission is used for updating parameters or firmware, then operational convenience is improved, but transmission range detection and signal reliability become challenging
Solution Approach 1:
The patent employs feedback mechanisms where the updating device emits detection signals and the target device responds with reaction signals. By analyzing the characteristics of these signals (such as signal strength, time of flight, or phase information), the system can estimate the distance between devices and determine whether they are within the effective communication range, providing feedback to control the updating process accordingly.
4Manufacturing precision
If conventional wired updating method is used, then firmware update accuracy is improved, but user convenience and market competitiveness deteriorate
Solution Approach 1:
The patent replaces the mechanical wired updating system with a wireless system that maintains firmware update accuracy through robust error handling protocols. The wireless transmission includes error detection codes, acknowledgment mechanisms, and automatic retry logic to ensure data integrity, matching the reliability of wired connections while providing significant user convenience through contactless operation.
Solution Approach 2:
The patent implements self-service functionality where the target device automatically receives and processes firmware updates wirelessly without requiring user intervention for cable connection or disconnection. The system autonomously manages the updating process, including initiating transfers, verifying data integrity, and completing installations, thereby maintaining accuracy while maximizing user convenience.
Data Source
AI summary
A method of automatically updating a datum is disclosed in the present invention. The method is applied to a signal outputting device and at least one signal receiving device for datum updating transmission. The method includes outputting a detecting signal to detect whether the signal receiving device is located within an effective range of the detecting signal, receiving a reacting signal generated according to the detecting signal, outputting a request of datum transmission when a distance is smaller than a threshold value, and transmitting the datum to the signal receiving device by wireless transmission when the request is allowed, so as to drive the signal receiving device to execute application program according to the updated datum. The detecting signal represents the distance between the signal outputting device and the signal receiving device.
