Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If human feedback is used to curate and annotate data, then data quality can be ensured, but the process requires large amounts of human resources and time

Engineering Contradiction:
Improvedata qualityVSAvoiddataset generation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-processing and pre-annotating 3D shape data using trained machine learning models before human review. The filtering pipeline pre-identifies high-quality shapes, the pose-alignment pipeline pre-determines canonical poses, and the annotation pipeline pre-generates captions, thereby reducing the time and human resources needed for final dataset generation while maintaining quality through subsequent human verification.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If human feedback is used for data curation, then accurate annotations can be obtained, but the process is prone to human error

Engineering Contradiction:
Improveannotation accuracyVSAvoiderror rate
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system implements self-service by enabling machine learning models to automatically perform data filtering, pose alignment, and annotation tasks. The trained models independently determine quality scores, align shapes to canonical poses, and generate captions without requiring continuous human intervention, thereby reducing human error while maintaining annotation accuracy through model-based consistency.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If manual selection of shapes and poses is performed, then high-quality datasets can be generated, but the process becomes complex and resource-intensive

Engineering Contradiction:
Improvedataset qualityVSAvoidcuration process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system segments the complex data curation process into three independent pipelines: (1) filtering pipeline that separates high-quality shapes from low-quality ones using quality scores, (2) pose-alignment pipeline that independently aligns shapes to canonical poses, and (3) annotation pipeline that independently generates captions. This segmentation reduces process complexity by allowing each pipeline to operate autonomously with specialized machine learning models while collectively producing high-quality datasets.

Inventive Principle:
Principle #1Segmentation

4Reliability

If extensive human review is conducted to ensure data quality, then accurate datasets can be produced, but productivity decreases

Engineering Contradiction:
Improvedataset accuracyVSAvoiddataset generation throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system replaces the mechanical human review process with automated machine learning-based pipelines. The filtering pipeline uses trained models to automatically assign quality scores and select high-quality shapes, the pose-alignment pipeline uses models to determine canonical poses, and the annotation pipeline uses models to generate captions. This substitution dramatically increases dataset generation throughput while maintaining accuracy through the automated consistency and scalability of machine learning models.

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

AI summary

In various examples, techniques for aligning shapes using pose information for AI systems and applications is described herein. Systems and methods described herein may use one or more pipelines that are configured to align shapes, such as three-dimensional shapes, using poses of the shapes. In some examples, to identify the poses, training images along with ground truth poses associated with the training images may be used to train a machine learning model. During and/or after the training, the machine learning model may then be used to process additional images in order to identify poses of additional shapes. In some examples, a pose associated with a shape may include a gravity orientation and/or an azimuth orientation of the shape as represented by an image. These poses may then be used to align the additional shapes, such as with respect to a canonical pose.
