Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for electronic payment services, such as those using NFC or Bluetooth, do not account for variations in the position of portable devices during transactions, leading to inefficiencies in multi-stage service processes like those found in coffee shops or food courts.
Innovation Solution
A wireless communication system with multiple devices corresponding to different stages of service, transmitting signals with varying radio field intensities to facilitate efficient communication and automation across stages, including order, preparation, and delivery, without the need for human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single wireless communication device is used for electronic payment services, then the system is simple to implement, but it cannot adapt to multi-stage service processes where device position varies
Solution Approach 1:
The service area is divided into multiple stages (order stage, preparation stage, delivery stage), and each stage is served by a dedicated wireless communication device. This segmentation allows the system to adapt to position variations across different service stages while maintaining manageable complexity through modular device deployment.
Solution Approach 2:
The system dynamically adjusts radio field intensity based on the current service stage. Each wireless communication device transmits signals with appropriate field strength suited to its specific stage requirements, enabling flexible adaptation to varying service conditions without requiring complete system redesign.
2Reliability
If radio field intensity is increased to ensure reliable communication, then communication reliability improves, but energy consumption increases
Solution Approach 1:
Each wireless communication device is configured with radio field intensity appropriate to its specific service stage and spatial requirements. The order stage device uses higher intensity for broader coverage, while delivery stage devices use lower intensity for localized communication, optimizing the balance between reliability and energy consumption for each local context.
Solution Approach 2:
The system changes the radio field intensity parameter according to the service stage. By adjusting this parameter dynamically rather than maintaining a fixed high level, the system ensures reliable communication when needed while reducing energy consumption during stages requiring less coverage.
