Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-rate transmitter devices are used for efficient data transmission, then data transmission rate is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent extracts only the essential identification information (item identifier code) from the complete item data set and transmits it via low-rate transmission. This selective extraction allows the system to achieve useful data transmission without requiring complex high-rate transmitter devices, thereby resolving the contradiction between transmission rate and device complexity.
Solution Approach 2:
The complete item data set is pre-stored in the mobile device before transmission occurs. When an item is detected, only the compact identification code needs to be transmitted and received, while the full information is already available locally. This preliminary preparation eliminates the need for transmitting large data sets in real-time, reducing transmitter complexity requirements.
2Productivity
If high-rate transmitter devices are used for efficient data transmission, then data transmission rate is improved, but power consumption increases
Solution Approach 1:
The patent transmits only the essential identification code rather than complete item information, significantly reducing the data volume that needs to be transmitted. This extraction approach enables the use of low-power, low-rate transmission devices while still achieving the goal of providing item information to the user.
Solution Approach 2:
Item information is pre-loaded into the mobile device's memory before the transmission event occurs. When the sensor detects an item's identification signal, the corresponding full information is already stored locally and can be retrieved immediately without requiring high-rate real-time transmission, thus reducing power consumption.
3Device complexity
If low-rate transmission is used to reduce complexity and power consumption, then device complexity and power consumption are reduced, but data transmission efficiency decreases
Solution Approach 1:
The patent identifies and transmits only the critical identification code portion of item information through low-rate transmission. This selective data extraction maintains transmitter simplicity while ensuring that the most important information (item identification) is transmitted efficiently, balancing complexity reduction with transmission effectiveness.
Solution Approach 2:
The mobile device acts as an intermediary that receives the low-rate identification signal and then provides access to the complete item information from its stored data set. This intermediary approach allows the use of simple low-rate transmitters while still delivering comprehensive information to the user through the mobile device's processing and display capabilities.
