Unified Communication Control for Zero-Power and Powered IoT Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT devices with zero power and non-zero power components require separate control devices, leading to high communication costs due to the need for additional hardware like RFID card readers, which increases hardware and communication expenses.
Innovation Solution
Utilizing different resources for communication between control devices and zero power devices versus non-zero power devices, ensuring no overlap, allowing the same control device to communicate with both types without interference, thus reducing communication costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate control devices are used for zero power devices and non-zero power devices, then communication reliability is improved, but device complexity and communication cost increase
Solution Approach 1:
The patent merges the control functions for zero power devices and non-zero power devices into a single control device. The control device includes both a first communication interface for communicating with non-zero power devices and a second communication interface for communicating with zero power devices, allowing one control device to manage both device types simultaneously, thereby reducing overall system complexity while maintaining communication reliability.
Solution Approach 2:
The control device is designed with multi-functionality to communicate with both zero power devices and non-zero power devices through different communication interfaces. This universal design allows the same control device to perform multiple communication functions, eliminating the need for separate dedicated control devices for each device type and reducing hardware complexity.
2Adaptability or versatility
If RFID card readers are added to control devices for zero power device communication, then communication capability is improved, but hardware cost increases
Solution Approach 1:
The control device integrates multiple communication capabilities into a single unit, with a first communication interface for non-zero power devices and a second communication interface for zero power devices. This multi-functional design eliminates the need for separate RFID card readers, reducing hardware costs while maintaining full communication capability for both device types.
Solution Approach 2:
The patent combines the communication functions that would traditionally require separate hardware (including RFID card readers) into a single integrated control device. By merging these communication capabilities, the system reduces hardware requirements and manufacturing costs while preserving the ability to communicate with both zero power and non-zero power devices.
3Device complexity
If the same control device communicates with both zero power and non-zero power devices using the same resource, then device complexity is reduced, but communication interference occurs
Solution Approach 1:
The patent segments the communication resources into distinct channels: a first communication interface for non-zero power devices and a second communication interface for zero power devices. This segmentation prevents communication interference by dedicating separate resources to different device types, while the control device itself remains unified, maintaining low complexity.
Solution Approach 2:
The control device implements local quality by assigning different communication interfaces with different characteristics to different device types. The first communication interface is optimized for non-zero power devices while the second communication interface is optimized for zero power devices, ensuring each communication channel has the appropriate properties for its intended use, thereby preventing interference.
