Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of identification information is used for device registration, then device registration can be performed, but the task becomes complex and error-prone for users
Solution Approach 1:
The patent replaces manual mechanical input operations with acoustic field-based automatic recognition. The measuring device emits ultrasonic waves containing identification information, which the information terminal automatically detects and processes, eliminating the need for manual typing or code scanning operations.
Solution Approach 2:
The measuring device automatically transmits its identification information through ultrasonic wave emission without requiring user intervention. The information terminal autonomously receives and processes this information, enabling the registration process to serve itself without complex user operations.
2Extent of automation
If code scanning or image capture methods are used for device registration, then automatic identification is achieved, but users still face complex tasks
Solution Approach 1:
The patent substitutes optical field-based code scanning with acoustic field-based ultrasonic wave detection. Instead of requiring users to capture images or scan codes, the system uses the information terminal's microphone to automatically receive ultrasonic waves containing identification information, greatly simplifying user operations.
3Adaptability or versatility
If Bluetooth pairing with advertisement information is used, then wireless pairing is enabled, but users cannot determine which device to pair when multiple devices are present
Solution Approach 1:
The patent uses acoustic field characteristics (ultrasonic wave emission) as a distinctive identifier for each measuring device, analogous to using color for identification. This allows users to clearly distinguish and identify the specific device emitting ultrasonic waves, even when multiple devices are present, solving the identification ambiguity problem in wireless pairing.
4Measurement precision
If additional communication means are added to improve device identification, then pairing accuracy improves, but system cost increases
Solution Approach 1:
The patent utilizes the existing speaker and microphone components of the measuring device and information terminal for ultrasonic communication, making these components serve multiple functions (audio output/input and device identification). This approach achieves accurate device identification without adding specialized communication hardware, thereby avoiding increased system cost and complexity.

AI summary
In an information management system according to the present invention, a measuring device including an output means including an oscillation device capable of generating ultrasonic waves causes the oscillation device to generate ultrasonic waves including identification information enabling the measuring device to be identified. An information terminal including a microphone capable of detecting the ultrasonic waves acquires the identification information from the ultrasonic waves via the microphone. The information terminal is caused to display the measuring device for which the identification information has been acquired. In a case where the information terminal receives an input indicating that the displayed measuring device is to be device-registered, the measuring device is device-registered on the information terminal.
