Solution Overview

Problem

Conventional adhered substance detection systems restrict other processing apparatuses when an adhered substance is detected, even if it does not cover the entire imaging surface, leading to incomplete functionality and reduced convenience in obstacle detection and recognition processes.

Innovation Solution

An adhered substance detection apparatus that divides the imaging surface into regions, allowing for the distinction between reliable and unreliable regions based on adhered substance detection, maintaining arithmetic processing reliability in unaffected areas and indicating unreliable regions for cautious use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If other processing apparatus is restricted when an adhered substance is detected, then detection accuracy is improved, but functionality and convenience are reduced

Engineering Contradiction:
Improvedetection accuracyVSAvoidfunctionality
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The imaging surface is divided into multiple regions, allowing the system to identify and isolate areas with adhered substances. This segmentation enables partial functionality to be maintained in regions without contamination while restricting processing only in affected areas, thus resolving the contradiction between detection accuracy and overall functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different reliability levels are assigned to different regions based on local contamination status. Regions with adhered substances are marked as unreliable, while clean regions maintain full reliability. This local differentiation allows the system to preserve functionality in unaffected areas while ensuring detection accuracy in contaminated areas.

Inventive Principle:
Principle #3Local quality

2Reliability

If other processing apparatus is restricted when an adhered substance is detected, then reliability of processing is improved, but convenience is reduced

Engineering Contradiction:
Improvereliability of processingVSAvoidconvenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system segments the imaging surface into reliable and unreliable regions, allowing convenient partial usage of processing apparatus in reliable regions while maintaining high reliability by restricting usage only in unreliable regions. This avoids complete system restriction and preserves user convenience.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system provides feedback information about the adhesion state to the user, enabling informed decisions about which processing functions to use. This feedback mechanism maintains reliability by alerting users to unreliable regions while preserving convenience by allowing continued use of reliable regions.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If the imaging surface is divided into regions for adhered substance detection, then detection precision is improved, but device complexity is increased

Engineering Contradiction:
