Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication cards lack an efficient and easy method for configuration, often requiring manual intervention through human machine interfaces like DIP switches, which complicates the setup process.
Innovation Solution
A communication card equipped with an antenna, memory, signal evaluation circuit, energy supply circuit, and signal processing circuit, where the energy supply circuit generates power from an electromagnetic signal received by the antenna, allowing configuration data to be wirelessly transferred and stored in the memory without the need for a supply voltage during the commissioning phase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration through human machine interface (DIP switches) is used, then configuration capability is provided, but device complexity and setup time increase
Solution Approach 1:
The patent replaces the mechanical DIP switch configuration system with a wireless electromagnetic signal-based configuration system. The communication card receives configuration data wirelessly through its antenna during commissioning, eliminating the need for manual mechanical switching and significantly simplifying the setup process.
Solution Approach 2:
The patent enables configuration data to be transmitted and stored in the memory before the communication card is fully installed or connected to power. The commissioning phase allows preliminary configuration through wireless communication, so that when the card enters normal operation, the configuration is already in place, reducing setup time and complexity.
2Productivity
If wireless configuration is enabled during commissioning, then configuration speed increases, but energy supply requirements increase
Solution Approach 1:
The patent performs configuration operations during a dedicated commissioning phase before normal operation begins. Configuration data is received and stored in memory during this preliminary phase, so that when the communication card enters normal operation, no additional configuration energy consumption is needed, and the configuration is already complete.
Solution Approach 2:
The communication card autonomously receives configuration data through its antenna and stores it in its own memory without requiring external configuration equipment or manual intervention. The card self-configures during the commissioning phase, eliminating the need for external configuration tools and reducing overall system complexity.
3Loss of time
If configuration is performed before power connection, then setup time decreases, but reliability of power supply decreases
Solution Approach 1:
The patent explicitly enables configuration data to be received and stored in the memory during a commissioning phase that occurs before the communication card is connected to the normal power supply. The card uses alternative power sources (such as battery or energy harvesting from the electromagnetic signal itself) during this preliminary configuration phase, ensuring that configuration can be completed before reliable power is available for normal operation.

Implementation Method 1
The energy supply circuit is coupled to the antenna for receiving electrical power from the antenna and is coupled to the signal evaluation circuit and the memory for providing electrical power to the signal evaluation circuit and the memory
