Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional checkout stations are used, then customers can be served, but queue buildup occurs and processing speed is limited
Solution Approach 1:
The patent replaces the mechanical interaction of manual item scanning and checkout with wireless RFID technology. Multiple items are detected simultaneously through electromagnetic fields generated by antennas in the walk-through gate, eliminating the sequential scanning process and enabling parallel processing of numerous items at once.
Solution Approach 2:
The invention transitions from a single-point checkout interaction to a multi-dimensional detection space. The walk-through gate creates a three-dimensional detection volume where items with RFID tags can be detected simultaneously from multiple angles and positions, allowing customers to pass through with multiple items without stopping at traditional checkout counters.
2Loss of time
If more checkout stations and attendants are allocated, then queue length is reduced, but store space is wasted and costs increase
Solution Approach 1:
The walk-through gate serves multiple functions simultaneously: it acts as a checkout station, a traffic flow regulator, and a customer guidance system. The curved transparent walls not only define the detection zone but also guide customers through the gate, eliminating the need for separate signage and multiple dedicated checkout lanes.
Solution Approach 2:
The system enables customers to perform their own checkout by simply walking through the gate with their items. The automated RFID detection and wireless communication between tags and antennas eliminate the need for cashiers to manually scan items, allowing customers to serve themselves without human intervention at the checkout point.
3Productivity
If more cashiers are dedicated to checkout, then service capacity increases, but operational costs and management complexity increase
Solution Approach 1:
The patent replaces human cashiers with an automated system consisting of RFID antennas, wireless communication modules, and processing units. The antennas continuously emit electromagnetic fields to detect RFID tags, and the system automatically processes transactions through wireless communication, eliminating the need for human operators at checkout stations.
4Illumination intensity
If transparent materials are used for walk-through gate walls, then visibility is maintained, but structural integrity and signal shielding may be compromised
Solution Approach 1:
The walk-through gate walls are constructed using composite materials that combine transparency with functional properties. The curved transparent walls are designed to maintain structural integrity while allowing light transmission, and the integration of antenna elements within or on the walls provides both structural support and RFID signal generation capabilities.
Solution Approach 2:
Different regions of the walk-through gate structure serve different functions: the curved transparent walls provide visibility and structural support, while embedded or mounted antenna elements provide RFID signal generation and reception. This local differentiation of material properties and functions allows the overall structure to meet multiple requirements simultaneously.
