Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If error correction mechanisms are continuously activated, then data transmission reliability is improved, but power consumption increases

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The error correction mechanism transitions from a static continuous operation mode to a dynamic conditional operation mode. The system continuously monitors syndrome values and adaptively activates the error correction module only when syndromes indicate errors are present, allowing the system to balance reliability and power consumption based on actual channel conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses its own transmitted data (syndrome values) to monitor its own health and automatically trigger error correction when needed. The transmitter includes error detection codes and the receiver calculates syndromes to self-diagnose error conditions, enabling the system to service itself without external intervention

Inventive Principle:

Principle #25Self-service

2Reliability

If error correction processing is performed on all received data, then error detection capability is improved, but processing time increases

Engineering Contradiction:

Improveerror detection capabilityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Instead of performing full error correction processing on all received data blocks, the system applies partial processing by first calculating lightweight syndrome values to detect potential errors. Full error correction processing is then applied only to blocks where syndromes indicate errors are present, reducing overall processing time while maintaining error detection capability

Inventive Principle:

Principle #16Partial or excessive action

3Manufacturing precision

If complex error correction algorithms are used, then manufacturing precision of communication system is improved, but device complexity increases

Engineering Contradiction:

Improvecommunication system performanceVSAvoiderror correction module complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The error correction system is segmented into distinct functional modules: syndrome calculation unit, error detection logic, and error correction processing unit. This modular segmentation allows each component to be optimized independently and simplifies the overall system architecture while maintaining high performance

Inventive Principle:

Principle #1Segmentation

AI summary

A receiver includes an error correction module. A syndrome value, calculated based on received signals, may be used to enable the error correction module. The error correction module includes an error generator, a Nyquist error estimator, and a decoder. The decoder uses error estimation generated by the Nyquist error estimator to correct the decoded data. There are other embodiments as well.
