Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the device continues energy search to capture signals from all devices, then the signal capture coverage is improved, but the signal receiving accuracy deteriorates due to interference from non-matched devices

Engineering Contradiction:

Improvesignal capture coverageVSAvoidsignal receiving accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The device performs preliminary address information acquisition and device matching before full signal reception. By checking address information in advance and identifying matched devices, the system prepares reception conditions beforehand, allowing it to selectively receive signals only from matched devices, thus avoiding interference from non-matched devices while maintaining comprehensive signal capture capability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The signal reception process is segmented into distinct phases: address information acquisition phase, device matching phase, and selective reception phase. This segmentation allows the device to first identify matched devices through address comparison, then separately process signals from matched versus non-matched devices, thereby improving signal receiving accuracy without sacrificing coverage

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If the device receives data fields from all frames, then the data reception completeness is improved, but the energy consumption increases due to processing unnecessary data from non-matched devices

Engineering Contradiction:

Improvedata reception completenessVSAvoidenergy consumption

Core Design Contradiction:

Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The device performs preliminary device matching based on address information before receiving data fields. By determining whether a transmitting device is matched in advance, the system avoids the energy-consuming process of receiving and processing data fields from non-matched devices, while ensuring complete reception of data from matched devices

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device extracts and compares address information from incoming frames to identify matched devices. This extraction mechanism allows the system to separate and selectively process only those frames containing data from matched devices, discarding frames from non-matched devices without full data reception, thereby reducing unnecessary energy consumption

Inventive Principle:

Principle #2Taking out (Extraction)

3Quantity of substance

If the device processes all received frames, then the data processing completeness is improved, but the processing time increases due to handling frames from non-matched devices

Engineering Contradiction:

Improvedata processing completenessVSAvoidprocessing time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The device performs preliminary device matching based on address information before full data field reception and processing. By identifying matched devices in advance through address comparison, the system prepares reception conditions beforehand, allowing it to quickly discard frames from non-matched devices without undergoing complete processing, thus reducing overall processing time while maintaining data processing completeness for matched devices

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device skips the complete data field reception and processing steps for frames identified as coming from non-matched devices. After preliminary address matching determines a device is not matched, the system rushes through by immediately discarding the frame without full processing, thereby significantly reducing processing time for unnecessary data while ensuring complete processing of relevant data from matched devices

Inventive Principle:

Principle #21Skipping (Rushing through)
