Solution Overview

Problem

Existing computer models for simulating immune responses are inaccurate due to their failure to correctly represent cellular interactions, particularly cell pairing and migration, which limits their suitability for vaccine development and immune system monitoring.

Innovation Solution

A computer-implemented method and system that simulate the interactions of T-cells and antigen-presenting cells by determining the numbers of naive, bound, and activated T-cells based on probabilities and random variables, accurately modeling binding, maturation, and division processes within a system boundary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing computer models are used to simulate immune responses, then computational speed is maintained, but accuracy of cellular interactions is insufficient

Engineering Contradiction:
Improveaccuracy of cellular interactionsVSAvoidcomplexity of simulation model
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The simulation model is segmented into distinct functional modules: a spatial component that handles cell positioning and migration, a kinetic component that manages binding and activation events, and a population component that tracks cell numbers. This modular segmentation allows each component to be optimized independently, improving overall accuracy without proportionally increasing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediary variables and intermediate computational steps that mediate between simplified input parameters and complex biological outcomes. These intermediaries include probabilistic transition functions and spatial distribution algorithms that bridge the gap between computational efficiency and biological realism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If detailed cellular interactions are modeled, then simulation accuracy improves, but computational time increases

Engineering Contradiction:
Improveaccuracy of cell pairing and migrationVSAvoidcomputational time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The simulation employs dynamic time-stepping where the integration step size adapts based on the current state of the system. During periods of rapid cellular interaction, smaller time steps are used to capture detailed events, while during quiescent periods, larger steps maintain efficiency. This dynamic approach preserves accuracy for critical events while reducing overall computational time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The model applies partial detailing selectively - full spatial and kinetic detail is applied only to cell populations and interactions that are critical to the specific research question, while less critical populations use simplified representations. This partial action approach maintains accuracy where needed without uniformly increasing computational burden across all cell types.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If probabilistic methods are used to model cell interactions, then biological variability is captured, but deterministic predictions become harder to obtain

Engineering Contradiction:
Improveability to model biological variabilityVSAvoidpredictive certainty
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The simulation incorporates feedback mechanisms where probabilistic outcomes from multiple simulation runs are aggregated to produce statistically robust predictions. The system uses feedback from population-level trends to adjust individual cell probabilistic parameters, ensuring that while individual cell behaviors remain stochastic, the overall population predictions become increasingly reliable and certain through repeated sampling.

Inventive Principle:
Principle #23Feedback
