Solution Overview

Problem

Current odor discrimination methods rely heavily on human olfaction, which is subjective, time-consuming, and labor-intensive, and existing sensing systems require numerous sensors to mimic human olfactory mechanisms, resulting in excessive data and calculation processing.

Innovation Solution

An information processing apparatus that uses a smaller number of sensors to obtain a larger number of indicators by combining sensor outputs, allowing for odor discrimination through indicator-value-patterns, reducing the need for extensive data processing and sensor numbers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a large number of sensors are used to mimic human olfactory mechanisms, then odor discrimination capability is improved, but device complexity and data processing requirements increase

Engineering Contradiction:
Improveodor discrimination capabilityVSAvoidnumber of sensors
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines outputs from multiple sensors to generate composite indicators that represent odor characteristics. Instead of processing each sensor output separately, the system merges sensor responses into integrated indicator values that capture essential odor information, thereby reducing complexity while maintaining discrimination capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts key odor-related information from sensor outputs by generating a smaller set of meaningful indicators. Rather than using all raw sensor data, the system identifies and extracts the most relevant features that distinguish different odors, reducing the data dimensionality while preserving discriminatory power

Inventive Principle:
Principle #2Taking out (Extraction)

2Measurement precision

If a large number of sensors are used to mimic human olfactory mechanisms, then odor discrimination capability is improved, but calculation processing amount increases

Engineering Contradiction:
Improveodor discrimination capabilityVSAvoidcalculation processing amount
Core Design Contradiction:
Measurement precisionVSPower

Solution Approach 1:

The patent extracts essential odor characteristics from sensor data by computing a limited number of indicator values that capture the most discriminative information. This extraction process reduces the calculation burden by focusing computational resources on the most relevant features rather than processing all sensor outputs equally

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines multiple sensor outputs into fewer indicator values through mathematical operations. This merging reduces the total number of calculations required while preserving the essential information needed for odor discrimination, as the combined indicators represent aggregated sensor responses

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If human olfaction is used for odor evaluation, then subjective discrimination is achieved, but time consumption and labor increase

Engineering Contradiction:
Improvesubjective discrimination capabilityVSAvoidevaluation speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces the human olfactory system with an automated sensor-based system that mimics human odor perception. Instead of relying on human specialists to evaluate odors subjectively, the system uses sensors combined with indicator generation to objectively assess odor characteristics, thereby eliminating time-consuming manual evaluation while maintaining discrimination capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates an artificial system that copies the functional aspects of human olfaction using sensors and computational indicators. By replicating the information processing aspects of human odor perception through indicator-value-patterns, the system achieves automated odor evaluation that substitutes for human sensory capabilities

Inventive Principle:
Principle #26Copying
