Solution Overview

Problem

Existing signal transmission systems fail to maintain transmission quality over long durations and in changing environmental conditions, as they do not continuously adjust transmission parameters, leading to potential deterioration in signal quality.

Innovation Solution

A signal transmission system comprising a signal sending device and a signal receiving device, where a sending controller and a reception controller monitor signal reception status and adjust signal sending and reception parameters based on real-time monitoring information to ensure optimal transmission quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If transmission parameters are adjusted only at link establishment time, then the system complexity is reduced, but transmission quality deteriorates over time due to environmental changes and device aging

Engineering Contradiction:
Improveparameter adjustment complexityVSAvoidtransmission quality
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the receiving device monitors signal reception quality and sends control signals back to the sending device to adjust transmission parameters. This continuous feedback loop ensures transmission quality is maintained despite environmental changes and device aging, resolving the contradiction between reduced complexity and maintained reliability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent transitions from one-time parameter adjustment at link establishment to continuous parameter adjustment throughout the link duration. The receiving device continuously monitors signal quality and triggers parameter adjustments as needed, ensuring transmission quality is maintained throughout the entire communication session rather than just initially.

Inventive Principle:
Principle #20Continuity of useful action

2Reliability

If transmission parameters are adjusted continuously to maintain quality, then transmission quality is maintained, but the time required for adjustment increases

Engineering Contradiction:
Improvetransmission qualityVSAvoidparameter adjustment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements periodic monitoring of signal reception quality at the receiving device, which triggers parameter adjustments only when quality degradation is detected. This periodic action rather than continuous adjustment maintains transmission quality while minimizing the time spent on parameter adjustments, resolving the contradiction between quality maintenance and adjustment time.

Inventive Principle:
Principle #19Periodic action

3Speed

If multiple transmission parameter values are prepared in advance for different operation modes, then switching between modes becomes faster, but the device complexity increases

Engineering Contradiction:
Improvemode switching speedVSAvoidparameter storage complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent prepares multiple transmission parameter values in advance for different operation modes (e.g., high-speed mode and power-saving mode). When mode switching is required, the system can quickly select and apply the pre-configured parameters without time-consuming real-time adjustment, thus achieving fast mode switching while managing device complexity through structured parameter organization.

Inventive Principle:
Principle #10Preliminary action
