Solution Overview

Problem

The existing methods for monitoring equipment in facilities, such as buildings, rely on subjective manual recordings of the installation environment, which are prone to individual differences and lack objectivity, making it difficult to accurately assess the condition of equipment based on environmental factors like dust and sunlight exposure.

Innovation Solution

An installing environment estimation device that utilizes data collected by sensors and cameras, employing a classification model to objectively estimate the environment by analyzing features such as dirty area and equipment density, allowing for more precise assessment of equipment conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual recording of installation environment is used, then ease of operation is improved, but measurement precision deteriorates due to subjective individual differences

Engineering Contradiction:
Improveease of operationVSAvoidmeasurement precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces the manual mechanical recording process with an automated image processing system. Cameras capture images of the installation environment, and image processing algorithms automatically analyze these images to extract environmental features such as dust accumulation, sunlight exposure, and surrounding objects. This substitution eliminates subjective human judgment while maintaining operational efficiency.

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

2Measurement precision

If automated image processing is used, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvemeasurement precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a classification model that serves multiple functions: it identifies various installation environment types (dusty, sunny, shaded, indoor, outdoor), extracts multiple environmental features simultaneously, and provides standardized assessment results. This multi-functional approach consolidates what would otherwise require multiple separate systems into a single unified device.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses image copying technology where cameras capture visual representations of the physical installation environment. These image copies are then processed digitally to extract environmental information, allowing the system to analyze the environment without physically interacting with or disturbing the actual installation site.

Inventive Principle:
Principle #26Copying

3Reliability

If comprehensive environmental data collection is implemented, then reliability is improved, but loss of time increases due to extensive data gathering

Engineering Contradiction:
ImprovereliabilityVSAvoidloss of time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent pre-establishes a classification model with defined environmental categories and assessment criteria before actual installation environment evaluation. This preliminary preparation allows the system to quickly match captured images against predefined categories, eliminating the need for time-consuming custom analysis during actual assessments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enables continuous automatic assessment of installation environments by integrating image capture and processing capabilities that can operate continuously or at regular intervals. This eliminates gaps in monitoring and provides ongoing reliable data without requiring repeated manual assessments, thereby reducing total time investment while maintaining continuous reliability.

Inventive Principle:
Principle #20Continuity of useful action
