Solution Overview

Problem

Current systems for videographic or photographic capture of multiple samples in sample chambers of a microtiter plate are inefficient due to the need to move the sample plate sequentially, which limits temporal resolution and introduces movement-induced distortions, and existing microscope arrays cannot be arranged closely enough to capture all sample chambers simultaneously due to electronics and lens size constraints.

Innovation Solution

A system with an array of microscopes, each with its own image capture chip and lens, arranged on a carrier board with separate data processing electronics positioned laterally or behind the chips, allowing for close proximity and synchronization of image capture from multiple sample chambers with minimal external movement influence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single microscope is used to capture multiple sample chambers sequentially, then the system complexity is low, but the acquisition time increases significantly and temporal resolution deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoidacquisition time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system divides the sample plate into multiple regions, with each region captured by a dedicated microscope in the array. This segmentation allows parallel acquisition of multiple sample chambers simultaneously, reducing total acquisition time while maintaining manageable system complexity through modular architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple microscopes are merged into a single integrated array system with shared control and processing electronics. This combining approach enables simultaneous capture of multiple sample chambers, dramatically improving temporal resolution while the shared infrastructure keeps overall system complexity controlled

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If the sample plate is moved sequentially between microscopes, then the device complexity remains low, but movement-induced distortions increase and measurement precision deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidmeasurement precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

Instead of moving the sample plate through a single microscope, the invention inverts the approach by bringing multiple microscopes to the sample plate simultaneously. This eliminates the need for plate movement during acquisition, preventing movement-induced distortions and maintaining high measurement precision for dynamic cell processes

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The microscopes are pre-positioned in an array configuration above the sample plate before acquisition begins. This preliminary arrangement allows all sample chambers to be captured simultaneously without subsequent movement, eliminating acceleration and deceleration effects that would distort cellular measurements

Inventive Principle:
Principle #10Preliminary action

3Productivity

If multiple microscopes are positioned closely to capture all sample chambers simultaneously, then the productivity increases, but the device complexity increases due to electronics and lens size constraints

Engineering Contradiction:
Improveparallel acquisition capabilityVSAvoidelectronics and lens arrangement
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention transitions from a single-point microscope configuration to a two-dimensional array of microscopes. This dimensional change allows simultaneous coverage of all sample chambers in parallel, dramatically increasing productivity while the systematic grid arrangement manages the complexity of multiple components through regular spacing and modular design

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