Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signal transmission devices lack a method to identify and match specifications, leading to potential overheating or damage when incorrectly connected to a signal processing system.
Innovation Solution
A method involving a signal processing system that reads attribute information from a memory device of the signal transmission device to determine its attributes and set appropriate signal output values, preventing excessive power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If signal transmission device specifications are marked on label or manual, then users can purchase correct products, but users cannot access specification information when label is removed or manual is unavailable
Solution Approach 1:
The patent embeds a memory device inside the signal transmission device, creating a nested structure where the information storage is contained within the device itself. This allows specification information to be accessed directly from the device without external labels or manuals, resolving the information accessibility problem while maintaining simplicity.
Solution Approach 2:
The patent introduces a memory device as an intermediary between the signal transmission device and the user's need for specification information. This intermediary stores and provides access to specification data, eliminating the need for external labels or manuals and ensuring information is always available.
2Ease of operation
If users connect signal transmission device without specification verification, then connection is simple, but device may overheat or be damaged due to mismatched specifications
Solution Approach 1:
The patent performs specification verification in advance by storing attribute information in the memory device and having the signal processing system read and verify this information before operation. This preliminary check ensures compatibility and prevents overheating or damage, while the automatic nature of the check maintains connection simplicity.
Solution Approach 2:
The patent implements a feedback mechanism where the signal processing system reads attribute information from the memory device, determines device attributes, and uses this information to control signal output parameters. This closed-loop feedback ensures safe operation by continuously matching device capabilities with operational parameters.
3Reliability
If signal processing system controls output based on attribute information, then device operation is safe, but system complexity increases due to identification capability
Solution Approach 1:
The patent enables the signal transmission device to serve itself by storing its own attribute information in an internal memory device. The signal processing system automatically reads and uses this information without requiring external intervention or complex identification procedures, achieving safe operation with minimal added complexity.

AI summary
A method for identifying a signal transmission device includes: reading attribute information from a memory device by a first device of a signal processing system, wherein the attribute information records information regarding at least one attribute of the signal transmission device that is coupled between the first device and a second device of the signal processing system; determining the at least one attribute of the signal transmission device by the first device according to the attribute information; and setting a maximum value or a minimum value of a signal output by the first device or the second device according to the at least one attribute.
