Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional data concentration devices are used, then data can be collected from multiple probes, but the device size becomes large and power consumption increases

Engineering Contradiction:

Improvedata concentration efficiencyVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by stationary object

Solution Approach 1:

The system segments the data concentration function into distributed data collection units at each probe, which locally process and compress data before transmission. This segmentation reduces the burden on central concentration devices, lowering their power consumption and size while maintaining high data collection efficiency from multiple probes

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces conventional mechanical/electronic data concentration architectures with a field-programmable gate array (FPGA) based system that implements parallel processing. This substitution enables high-speed data acquisition and compression with reduced power consumption and smaller device footprint compared to traditional approaches

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the number of probes increases for larger diameter pipelines, then detection coverage improves, but data transmission complexity and device size increase

Engineering Contradiction:

Improvepipeline diameter adaptabilityVSAvoiddata concentration device complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The FPGA-based data concentration device implements a universal architecture that can adapt to different numbers of probes and pipeline diameters. The reconfigurable logic allows the same device to handle varying data loads from different probe configurations, providing pipeline diameter adaptability without increasing device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system transitions from serial data processing to parallel processing across multiple channels simultaneously. By utilizing the temporal and spatial dimensions of data acquisition, the system can handle increased probe counts for larger pipelines without proportionally increasing device complexity, as multiple data streams are processed concurrently rather than sequentially

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Speed

If data from all probes is transmitted simultaneously, then data acquisition speed improves, but data transmission bandwidth requirements increase

Engineering Contradiction:

Improvedata acquisition speedVSAvoiddata transmission volume

Core Design Contradiction:

SpeedVSQuantity of substance

Solution Approach 1:

Data compression and filtering operations are performed preliminarily at each probe before transmission. This preliminary processing reduces the volume of data that needs to be transmitted while maintaining high acquisition speed, as only essential compressed data is sent through the transmission channel

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system merges multiple data streams from different probes into a single consolidated data flow for transmission. By combining and compressing data at the source before transmission, the system achieves high acquisition speed across multiple probes while reducing the total transmission bandwidth required compared to transmitting all raw data separately

Inventive Principle:

Principle #5Merging (Combining)
