Solution Overview

Problem

Current methods for assessing human embryo viability in IVF are invasive, unreliable, and fail to accurately predict implantation potential due to noisy biological images and errors in automated cell tracking, leading to erroneous decisions in embryo selection for transfer.

Innovation Solution

An apparatus and method for automated, non-invasive cell activity tracking using a hypothesis selection module to determine inferred characteristics of cells based on geometric features, with a confidence estimation module to assess the reliability of these hypotheses, allowing for accurate evaluation of embryo viability without invasive methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated cell tracking is used to assess embryo viability, then productivity is improved, but measurement precision deteriorates due to noisy biological images and tracking errors

Engineering Contradiction:
Improveembryo assessment efficiencyVSAvoidcell tracking accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system implements feedback mechanisms where tracking results are continuously refined. The hypothesis selection module uses feedback from image data and previous tracking results to adjust and improve cell position and boundary estimates, thereby maintaining measurement precision while achieving automated high-throughput assessment

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary hypothesis selection module that acts as a mediator between raw image data and final viability assessment. This module generates multiple hypotheses about cell states and selects the most probable ones, effectively filtering noise and tracking errors to maintain precision while enabling automated processing

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If invasive methods are used to assess embryo quality, then measurement precision is improved, but object-affected harmful factors increase

Engineering Contradiction:
Improveembryo quality assessment accuracyVSAvoidembryo integrity disruption
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces invasive mechanical assessment methods with non-invasive optical imaging and computational analysis. Time-lapse microscopy captures embryo development without physical contact, and automated image analysis algorithms assess viability based on morphological and temporal patterns, eliminating physical disruption while maintaining assessment accuracy

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

Solution Approach 2:

The hypothesis selection module serves as an intermediary that extracts viability information from non-invasive time-lapse images. By analyzing temporal patterns of cell division and morphological changes across multiple time points, the system achieves accurate quality assessment without direct intervention or disruption to the embryo

Inventive Principle:
Principle #24Intermediary (Mediator)
