Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing neural network-based systems are used, then general event detection is possible, but they fail to effectively identify events based on temporal discrepancies in factoid answers

Engineering Contradiction:
Improveevent detection accuracyVSAvoidtemporal change information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The system segments the temporal information by dividing it into discrete time points (t1, t2, t3) and extracts factoid answers at each segment. This segmentation allows the neural network to process temporal changes in a structured manner, comparing answers across different time segments to detect discrepancies that indicate events.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system adds a temporal dimension to the factoid answer analysis by organizing answers in a time-series structure. Instead of treating answers as static data points, the patent introduces time as an additional dimension, enabling the neural network to detect changes across time points and identify events based on temporal discrepancies.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If temporal analysis of factoid answers is implemented, then hidden events can be detected, but system complexity increases

Engineering Contradiction:
Improveevent identification reliabilityVSAvoidneural network training complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-processing the temporal data into structured factoid answers before neural network training. Answers are extracted, organized by time points, and prepared in advance, which simplifies the subsequent training process and reduces the computational complexity of the neural network while maintaining reliable event detection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary layer that transforms raw temporal data into structured factoid answers. This intermediary processing step acts as a mediator between the complex temporal data and the neural network, simplifying the input structure and reducing the overall system complexity while preserving the essential temporal information needed for reliable event detection.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method trains a neural network to identify an event based on discrepancies in answers to factoid questions at different times. One or more processors identify answers to a series of factoid questions. The processor(s) compare the answers from the series of factoid questions in order to determine discrepancies in the answers at different times, and then train a neural network to identify an event based on the discrepancies in the answers at the different times.
