Solution Overview

Problem

Existing sample handling systems in medical and chemical laboratories lack the ability to continuously and simultaneously monitor multiple samples in a cost-effective manner, often requiring multiple cameras for gapless monitoring, which is costly and inefficient.

Innovation Solution

A sample handling system comprising a camera module positioned away from the sample transport device to provide a free field of view, a processor to process images, and a control unit to control system functionality, enabling continuous monitoring of multiple samples with a reduced number of cameras.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple cameras are used for gapless monitoring of samples, then monitoring coverage is improved, but system cost increases

Engineering Contradiction:
Improvemonitoring coverageVSAvoidsystem cost
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple camera views into a single unified monitoring system. The image processing unit merges images from multiple cameras to create a comprehensive view of the transport device, allowing complete monitoring coverage while using a limited number of cameras. This resolves the contradiction by achieving full coverage (improving reliability) without deploying multiple cameras throughout the system (controlling device complexity and cost).

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The monitoring system is designed to perform multiple functions: detecting sample container positions, identifying spills, monitoring traffic flow, and tracking container alignment. A single integrated monitoring system with image processing capabilities replaces what would otherwise require multiple specialized detection devices, achieving universal monitoring coverage while reducing system complexity and cost.

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

2Measurement precision

If cameras are positioned close to the sample transport device, then image detail is improved, but field of view is limited

Engineering Contradiction:
Improveimage detailVSAvoidfield of view
Core Design Contradiction:
Measurement precisionVSArea of stationary object

Solution Approach 1:

The patent positions cameras at a distance from the transport device, utilizing the vertical dimension and angular perspective to achieve both detailed imaging and broad field of view. By strategically positioning cameras above and at angles to the transport device, the system captures comprehensive views of multiple sample holders simultaneously while maintaining sufficient image detail for detection purposes.

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

Solution Approach 2:

The system uses image processing algorithms that can dynamically adjust to capture relevant details from distance. The processing unit enhances image quality and extracts meaningful information even when cameras are positioned farther away, allowing the system to maintain measurement precision while expanding the field of view through computational methods.

Inventive Principle:
Principle #15Dynamics
