Solution Overview

Problem

Existing image acquisition systems face challenges with compactness, ease of access to optical components, and operator guidance due to bulky illuminators, which complicate maintenance, adjustment, and precision focusing, especially when installed at heights that obscure status LEDs and require additional screens for correct configuration.

Innovation Solution

The design of an illuminator with a modular structure allowing easy access to optical components, integrated heat dissipation, and visual and acoustic indicating means, such as laser pointers and LEDs, to facilitate operator guidance and reduce the need for external screens, enabling efficient maintenance and precise adjustments without disassembling the system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the illuminator is made compact to improve overall system compactness, then the system size is reduced, but access to optical components becomes difficult requiring disassembly

Engineering Contradiction:
Improvesystem sizeVSAvoidaccess to optical components
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The illuminator housing is segmented into a front portion and a rear portion that can be separated. The optical component is accessible from the rear portion, allowing maintenance and adjustment without disassembling the entire illuminator, thus resolving the contradiction between compactness and ease of access.

Inventive Principle:
Principle #1Segmentation

2Strength

If the illuminator housing is solid to protect internal components, then protection is improved, but access to optical components requires full disassembly

Engineering Contradiction:
Improveprotection of internal componentsVSAvoidmaintenance of optical components
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The housing is divided into separable front and rear portions. The rear portion can be removed to access optical components for maintenance, while the front portion remains intact to maintain structural strength and protection when assembled.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If status LEDs are placed on the front of the illuminator for visibility, then operator guidance is improved, but they become obscured when installed at heights

Engineering Contradiction:
Improveoperator guidanceVSAvoidvisibility of status indicators
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

Status indicators are moved from the front horizontal plane to the rear vertical surface of the illuminator housing. This spatial relocation allows operators to view status LEDs from below or the side, preventing obscuration when the illuminator is mounted at heights on overhead conveyors.

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

4Ease of operation

If additional screens are added to provide operator guidance, then visibility is improved, but device complexity increases

Engineering Contradiction:
Improveoperator guidanceVSAvoidsystem configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The illuminator housing itself serves as the display medium by incorporating status LEDs directly on its rear surface. This eliminates the need for external screens or additional display devices, reducing system complexity while maintaining operator guidance functionality.

Inventive Principle:
Principle #25Self-service
