Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a first adaptation algorithm is used to generate channel parameters, then the circuit can process input signals using a standardized algorithm, but the parameters may become erroneous or suboptimal when the algorithm is ill-suited for certain conditions

Engineering Contradiction:

Improveadaptability of channel parameter generationVSAvoidreliability of channel parameters

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a second adaptation algorithm as an intermediary mechanism to generate alternative channel parameters when the first algorithm produces erroneous results. This mediator algorithm provides a backup pathway that ensures reliable parameter generation even when the primary algorithm fails, directly resolving the contradiction between adaptability and reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the algorithmic parameters by switching between two different adaptation algorithms based on performance criteria. When the first algorithm's parameters become unreliable, the system transitions to using parameters generated by the second algorithm, thereby maintaining reliability while preserving adaptability through parameter variation.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the circuit switches to a second adaptation algorithm to correct parameter errors, then the reliability of signal processing improves, but the device complexity increases due to multiple algorithms

Engineering Contradiction:

Improvereliability of signal processingVSAvoidcomplexity of adaptation circuit

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic selection mechanism that activates the second adaptation algorithm only when needed, based on detecting failures or suboptimal performance of the first algorithm. This dynamic approach maintains high reliability by having a backup ready while avoiding the constant complexity of fully activating both algorithms simultaneously.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent extracts the essential functionality of the second algorithm only when required, rather than permanently integrating both full algorithms. By taking out only the necessary parameter generation capability from the second algorithm and using it selectively, the system improves reliability without permanently increasing device complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

3Measurement precision

If approximated channel parameters are used from a second algorithm, then accurate signal processing can be maintained when the first algorithm fails, but the computational overhead increases

Engineering Contradiction:

Improveprecision of channel parametersVSAvoidcomputational energy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by using the second adaptation algorithm only partially - specifically when the first algorithm fails - rather than continuously. This selective application maintains measurement precision when needed while minimizing computational energy consumption by avoiding unnecessary execution of the second algorithm during normal operation.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent prepares approximated channel parameters from the second algorithm in advance or on-demand only when failures are detected, rather than pre-computing and storing all possible parameters. This preliminary action approach ensures precision availability when needed while reducing computational energy usage by avoiding extensive pre-computation.

Inventive Principle:

Principle #10Preliminary action
