Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If calibration files are stored on the detection device itself, then the device can operate independently offline, but the calibration time is long and production efficiency is reduced
Solution Approach 1:
The calibration file storage function is extracted from the detection device and relocated to an external server. The detection device retains only the minimal capability to perform detection, while the calibration file management (storage, retrieval, updates) is handled externally, thus reducing calibration time and improving production efficiency while maintaining offline operation capability through cached files.
Solution Approach 2:
A server acts as an intermediary between multiple detection devices and calibration files. Instead of each device independently storing and managing its own calibration files (which causes production bottlenecks), the server centralizes calibration file management, allowing multiple devices to efficiently access and update calibration files without conflicting with each other's production workflows.
2Ease of manufacture
If calibration files are written from dedicated interfaces on circuit boards during production line calibration, then calibration can be performed, but the operations become cumbersome and production efficiency is reduced
Solution Approach 1:
The mechanical/manual process of writing calibration files through dedicated circuit board interfaces during production line calibration is replaced with an automated wireless transmission system. Calibration files are transmitted automatically via wireless communication (WiFi, Bluetooth, or other protocols) between the server and detection devices, eliminating the need for physical interface connections and manual operations, thereby simplifying the calibration process and improving production efficiency.
3Reliability
If calibration files are stored locally on the detection device, then the device can function independently, but if the calibration file is accidentally deleted, the device cannot compensate for detection results, affecting user experience
Solution Approach 1:
The system implements a distributed storage architecture where calibration files exist in two locations: locally on the detection device for fast access and independently on an external server for safety. This dual-location strategy ensures that if the local file is deleted or corrupted, the device can retrieve a fresh copy from the server, thus protecting against information loss while maintaining detection accuracy and offline operation capability.
Solution Approach 2:
The system proactively establishes a backup mechanism by storing calibration files on an external server before any potential data loss occurs. This advance preparation creates a safety cushion against accidental deletion, corruption, or other data loss scenarios, ensuring that detection devices can always recover their calibration files and maintain accurate detection results without user intervention.

AI summary
A calibration method of a detection device and a method for acquiring a calibration file of the detection device are described herein. The acquisition method includes generating the calibration file in an address space accessible by the detection device in a use environment according to a calibration result, and correspondingly storing a unique identification code, the calibration result, and the calibration file of each detection device. When the detection device detects an article, the method includes attempting to acquire the calibration file from itself. If the calibration file can be acquired, the method includes directly loading the calibration file. If the calibration file cannot be acquired, the method includes acquiring the calibration file from the address space accessible by the detection device in the use environment. The solution is applied to the calibration of the detection device on a production line and the use of the detection device.
