Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual price tag updating is used, then system complexity is low, but labor intensity and error risk increase significantly
Solution Approach 1:
The electronic label system performs automatic price updates through self-service mechanisms. The base station communicates price information wirelessly to electronic labels, which automatically display the updated prices without requiring manual intervention. This eliminates the labor-intensive process of manually finding products and replacing price tags while maintaining system simplicity.
Solution Approach 2:
The patent replaces the mechanical system of manual price tag handling with an electronic communication system. Instead of physically moving and replacing paper or plastic price tags, the system uses wireless communication between the base station and electronic labels to transmit price updates, thereby reducing labor intensity while keeping device complexity manageable.
2Productivity
If electronic label systems are used for centralized price updates, then price information updating is accelerated, but the system fails to provide detailed product status and location information
Solution Approach 1:
The electronic label system is designed with multi-functionality to serve multiple purposes. In addition to displaying price information and enabling centralized price updates, the system incorporates RFID tags and readers to detect product quantities and locations. This universal approach allows a single system to handle both price management and inventory tracking without sacrificing either function.
Solution Approach 2:
The patent merges the electronic label system with RFID technology to combine price display functionality with inventory management capabilities. By integrating RFID tags into products and using readers at the base station, the system simultaneously tracks product locations and quantities while maintaining the ability to update prices centrally, thus preventing information loss.
3Difficulty of detecting and measuring
If RFID tags are used for remote reading, then product detection capability is improved, but system complexity and integration requirements increase
Solution Approach 1:
The system merges RFID reading functionality with the existing electronic label base station. The base station that already communicates with electronic labels is enhanced to also include RFID reading capabilities, allowing it to detect products with RFID tags. This integration approach improves product detection capability while minimizing additional system complexity by combining functions into a single platform.
4Loss of information
If inventory tracking systems are implemented, then product quantity and location information is available, but manual operations and errors persist
Solution Approach 1:
The system implements self-service automation where the base station automatically queries RFID tags to detect product quantities and locations, and automatically updates electronic labels with price information. This automated process eliminates manual inventory tracking operations and reduces human errors while ensuring continuous availability of accurate inventory information.
Solution Approach 2:
The system incorporates feedback mechanisms where the base station receives information from RFID readers about product locations and quantities, processes this information, and automatically updates the electronic labels and inventory management system. This closed-loop feedback approach ensures real-time inventory information availability while minimizing manual intervention and associated errors.
