Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
M2M devices face challenges in configuration and data exchange without a user interface and power supply, as existing solutions require a power source or user interaction for setup and data access.
Innovation Solution
The device uses a communication module that can be powered by an external radio field, allowing data exchange between a reader unit and control module independently of the device's power supply, enabling configuration and data access without a user interface or power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user interface with display and input unit is provided for configuring the M2M device, then the device can be configured by the user, but the device becomes more complex and costly and requires power supply
Solution Approach 1:
The patent introduces a portable reader unit as an intermediary device that contains the user interface and configuration logic. The reader unit communicates with the M2M device via radio frequency, allowing users to configure M2M devices without adding complexity or power requirements to the M2M devices themselves. The reader unit serves as a mediator that handles all user interaction while the M2M device remains simple and power-independent.
2Ease of operation
If a user interface is provided for configuring and reading data from the M2M device, then the device can be configured and accessed, but the device requires power supply which may not be available at the site of operation
Solution Approach 1:
The portable reader unit acts as a power-providing intermediary that energizes the M2M device through electromagnetic induction during communication. The reader unit generates a radio frequency field that simultaneously powers the M2M device's communication circuitry and enables data exchange, eliminating the need for separate power supply at the M2M device installation site.
Solution Approach 2:
The patent replaces the mechanical/electrical power connection system with an electromagnetic field-based power transmission system. Instead of requiring physical power cables or batteries at the M2M device, the system uses wireless electromagnetic induction to transfer energy from the reader unit to the M2M device, enabling power-free operation at the installation site.
3Adaptability or versatility
If the M2M device stores configuration data and operational data, then the device can function independently, but the device requires power supply for storing and accessing data
Solution Approach 1:
The portable reader unit serves as a data storage intermediary that maintains configuration templates and operational data. During communication sessions, the reader unit transfers data to and from the M2M device's memory, enabling the M2M device to store and access data without requiring continuous power. The reader unit can also serve as a backup storage medium.
