Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal device continues to turn on circuits to receive repeatedly transmitted data, then the data reception capability is maintained, but the power consumption increases

Engineering Contradiction:

Improvedata reception capabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by predicting data before it is actually received. The terminal device generates predicted data in advance based on previously received data patterns, so when the actual data arrives, the device can quickly compare and verify against the pre-generated prediction, avoiding the need to keep circuits continuously active for repeated reception attempts

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the terminal device waits for retransmission after failing to receive data, then the data integrity is ensured, but the communication delay increases

Engineering Contradiction:

Improvedata integrityVSAvoidcommunication delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The terminal device performs preliminary data prediction and generates expected data patterns before the actual transmission completes. When data is received, the device can immediately compare against the predicted data to verify integrity, eliminating the need to wait for retransmission and significantly reducing communication delay while maintaining data integrity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by using previously received data to generate predictions about upcoming data. This feedback mechanism allows the terminal device to continuously update its predictions based on historical patterns, enabling early verification of received data without waiting for retransmission, thus reducing delay while ensuring integrity

Inventive Principle:

Principle #23Feedback

3Measurement precision

If the terminal device performs complete decoding process, then the decoding accuracy is ensured, but the power consumption and processing time increase

Engineering Contradiction:

Improvedecoding accuracyVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The terminal device performs preliminary decoding by generating predicted data before complete reception. This allows the device to start verification early and terminate the complete decoding process as soon as the predicted data matches the received data, ensuring decoding accuracy while significantly reducing power consumption by avoiding unnecessary complete decoding cycles

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies partial action by performing only the necessary portion of the decoding process. Instead of always completing the full decoding sequence, the device performs decoding partially and terminates early when the predicted data matches the received data, maintaining accuracy while reducing energy consumption by avoiding excessive processing

Inventive Principle:

Principle #16Partial or excessive action

4Measurement precision

If the terminal device performs complete decoding process, then the decoding accuracy is ensured, but the processing time increases

Engineering Contradiction:

Improvedecoding accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The terminal device performs preliminary decoding by generating predicted data before complete reception. This enables early termination of the decoding process when the prediction matches the received data, ensuring decoding accuracy is maintained while significantly reducing the time required for complete decoding

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies skipping by allowing the terminal device to rush through the decoding process selectively. When the predicted data matches the received data, the device skips the remaining unnecessary decoding steps and proceeds directly to data processing, maintaining accuracy while minimizing processing time

Inventive Principle:

Principle #21Skipping (Rushing through)
