Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID systems face challenges in securely mounting RFID readers on storage containers without exposing electrical connections, and in efficiently scanning multiple containers using a single reader with multiple antennae, while also requiring a networked system for inventory management.
Innovation Solution
A modular RFID reader apparatus with an enclosure that can be mounted on storage containers, featuring an RFID reader and antenna configuration where electrical connections are not externally accessible, and a networked system with a master controller managing multiple RFID readers and antennae for simultaneous scanning across multiple containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the RFID reader is mounted on the exterior surface of the storage container with an external antenna, then the RFID reading function can be achieved, but the electrical connection becomes externally accessible and vulnerable to tampering
Solution Approach 1:
The patent applies nesting by placing the RFID reader inside an enclosure that is mounted on the exterior surface of the storage container, while the antenna is positioned inside the container. The electrical connection passes through a sealed opening in the enclosure, nesting the reader within the enclosure structure to protect connections while maintaining external mounting.
Solution Approach 2:
The enclosure acts as an intermediary component between the RFID reader and the external environment. It provides a sealed mounting structure that protects electrical connections from external access while allowing the reader to function with an internally positioned antenna.
2Productivity
If multiple RFID readers are used to scan multiple storage containers simultaneously, then scanning efficiency is improved, but hardware cost and system complexity increase
Solution Approach 1:
The patent makes the RFID reader universal by enabling a single reader to work with multiple antennas. The reader can be configured to scan multiple storage containers simultaneously by switching between or using multiple antennas, allowing one reader to perform the work of multiple readers.
Solution Approach 2:
The patent merges multiple scanning functions into a single RFID reader by combining it with multiple antennas. The reader consolidates the scanning capability for multiple containers, reducing the total number of readers needed while maintaining simultaneous scanning productivity.
3Device complexity
If a single RFID reader is used to scan multiple storage containers, then hardware cost is reduced, but the ability to perform simultaneous scanning decreases
Solution Approach 1:
The patent introduces dynamics by enabling the RFID reader to dynamically switch between or activate multiple antennas based on which storage container needs scanning. This dynamic antenna selection allows a single reader to maintain simultaneous scanning capability across multiple containers by adapting its antenna configuration in real-time.
