Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID systems face challenges in providing a uniform method for discovering, configuring, and communicating with diverse RFID devices across different vendors and protocols, leading to complexity in setup, maintenance, and compatibility within the RFID ecosystem.
Innovation Solution
The introduction of a Device Service Provider Interface (DSPI) component that acts as an abstraction layer to manage and communicate with RFID devices uniformly, facilitating discovery, configuration, and connection management, regardless of device type or brand, through a receiver component, request-response component, device interface component, and SPI container component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a Device Service Provider Interface (DSPI) component is introduced as an abstraction layer, then compatibility and ease of operation are improved, but device complexity increases
Solution Approach 1:
The patent introduces a Device Service Provider Interface (DSPI) component as an intermediary layer between the RFID server and diverse RFID devices. This DSPI component provides a standardized interface that abstracts the complexities of different device protocols and vendors, allowing the server to communicate uniformly with all devices without directly handling device-specific variations. The DSPI acts as a mediator that translates between the standardized server interface and device-specific implementations, thereby improving ease of operation while managing complexity through abstraction.
2Adaptability or versatility
If multiple RFID device protocols and vendors are supported directly, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal Device Service Provider Interface (DSPI) component that can handle multiple RFID device protocols and vendors through a single standardized interface. The DSPI is designed to be multi-functional, supporting discovery, configuration, and communication with diverse RFID devices from different vendors using different protocols. This universal interface allows the system to adapt to various device types without creating separate handling mechanisms for each protocol or vendor, thereby achieving adaptability while preventing complexity through consolidation.
3Measurement precision
If device-specific communication methods are used for each RFID device, then measurement precision is improved, but ease of operation worsens
Solution Approach 1:
The patent segments the communication system into two distinct layers: a standardized upper layer (DSPI interface) that provides uniform ease of operation, and a device-specific lower layer that handles protocol-specific precision requirements. The DSPI component is divided into standardized methods for discovery, configuration, and communication, while device-specific protocol handling is encapsulated within the DSPI implementation. This segmentation allows the upper layer to remain simple and uniform while the lower layer maintains precision for specific device protocols, resolving the contradiction between ease of operation and measurement precision.
