Solution Overview

Problem

Micro-scale calorimeter chamber (MCC) data is prone to inaccuracies due to 'artifacting' and lacks the ability to automatically break down combustion data into individual peaks, making it unsuitable for detailed analysis.

Innovation Solution

A system that corrects MCC data using a baseline to accurately calculate values like total heat release and effective heat release capacity, and automatically generates individual peaks for different compositions, utilizing a baseline correction module and graphical user interface for visualization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If raw MCC data is used for combustion analysis, then the data processing is simple, but the measurement precision deteriorates due to artifacting from temperature-induced gas expansion

Engineering Contradiction:
Improveaccuracy of MCC dataVSAvoidcomplexity of data processing system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by performing baseline correction on the raw MCC data before combustion analysis. The system automatically identifies and corrects artifacting caused by temperature-induced gas expansion, preparing the data in advance for accurate analysis. This resolves the contradiction by improving measurement precision through pre-processing while keeping the overall system complexity manageable through automation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary baseline correction module that acts as a mediator between the raw MCC data and the combustion analysis. This module automatically identifies artifacting patterns and corrects them, serving as an intermediate processing step that improves data accuracy without requiring complex manual intervention. The intermediary handles the complexity of artifact removal, allowing simple combustion analysis downstream.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If MCC data is visualized as a whole, then the visualization is simple, but the loss of information increases because individual combustion peaks cannot be distinguished

Engineering Contradiction:
Improvedetail of combustion dataVSAvoidcomplexity of data breakdown system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies segmentation by automatically breaking down the composite MCC data into individual combustion peaks corresponding to different sample compositions. The system identifies and separates overlapping combustion events, preserving detailed information about each peak while maintaining an integrated view. This resolves the contradiction by preventing information loss through automatic peak decomposition without requiring complex manual analysis.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements self-service through automated peak identification and decomposition algorithms that independently analyze and separate combustion peaks without user intervention. The system serves itself by automatically detecting artifacting, correcting baselines, and resolving individual peaks from composite data. This prevents information loss while keeping the interface simple, as the complex decomposition happens automatically.

Inventive Principle:
Principle #25Self-service

3Measurement precision

Core Design Contradiction:

Solution Approach 1:

The patent applies feedback through automated algorithms that iteratively identify and refine peak positions, shapes, and intensities based on the corrected baseline data. The system uses feedback loops to adjust peak parameters until optimal separation is achieved, eliminating subjective guessing. This improves measurement precision through objective, repeatable automated analysis while maintaining reasonable automation levels.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces the mechanical process of manual peak identification with automated computational algorithms. Instead of relying on human operators to visually inspect and guess peak positions, the system uses computer-based algorithms to objectively identify and decompose peaks. This substitution improves precision by eliminating human subjectivity while implementing practical automation through software-based analysis.

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

AI summary

A method for microscale calorimeter chamber data manipulation and visualization includes receiving a dataset from a microscale calorimeter chamber. The dataset is indicative of heat release rates for a test material as a function of a temperature applied by the microscale calorimeter chamber to the test material. The method further includes generating a baseline for correcting the heat release rates for the test material based on a selected temperature interval of the dataset. The method also includes generating a modified dataset that includes modified heat release rate values for the test material based on the baseline. The method includes generating a graphical user interface and displaying, via the graphical user interface, a graphical depiction of the modified dataset.
