Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a device with a large storage space is used to store more temperature data, then the storage capacity is improved, but the cost increases
Solution Approach 1:
The patent applies asymmetric data representation by converting temperature data from decimal format to a specialized binary format where only the significant bits are stored. This asymmetric transformation allows the same storage space to hold much more data without increasing physical storage capacity or cost.
Solution Approach 2:
The patent changes the parameter representation by storing temperature data in a compressed binary format rather than standard decimal format. This parameter transformation reduces the number of bits required to represent each temperature value, thereby increasing effective storage capacity without additional hardware cost.
2Adaptability or versatility
If USB or Bluetooth communication is adopted for data transmission, then the data transmission capability is improved, but the device size increases
Solution Approach 1:
The patent extracts the data transmission function from the temperature recorder device itself, allowing data to be read directly from the compressed storage format through NFC without requiring USB or Bluetooth modules. This extraction eliminates the need for bulky communication hardware while maintaining data transmission capability.
Solution Approach 2:
The patent uses NFC technology to create a wireless copy interface for data transmission, replacing physical USB connections and Bluetooth modules. The NFC copy mechanism allows data to be transferred without requiring large communication hardware components in the device.
3Volume of moving object
If NFC is adopted for data transmission, then the device size is reduced, but the data transmission speed decreases when the amount of data is large
Solution Approach 1:
The patent performs preliminary compression of temperature data into a compact binary format before storage. This preliminary action reduces the total volume of data that needs to be transmitted, thereby increasing transmission speed when using NFC without requiring larger communication hardware.
Solution Approach 2:
The patent transforms the data parameter representation to a compressed binary format, changing the data structure to require fewer bits per temperature reading. This parameter change reduces the total data size for transmission, thereby improving NFC transmission speed despite its inherent bandwidth limitations.

AI summary
Collecting and storing temperature data includes acquiring a starting time at a temperature recording time period and acquiring temperature data for each time stamp. The target compressed data corresponding to the temperature recording time period is obtained by compressing the temperature data. The starting time data and the target compressed data corresponding to the temperature recording time period is stored in a temperature recorder. Multiple temperature data points may correspond to one piece of compressed data, so that each piece of temperature data only occupies a small amount of storage space. The starting time data and multiple pieces of compressed data are stored in the temperature recorder together, allowing improved storage performance of the temperature recorder and rapid collection of the temperature data. A blockchain-based verification for the collected temperature data ensures the security and authenticity of the data collection and prevents the data from being tampered with.
