Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a neural network is trained to identify elements in digitized images, then the accuracy of element recognition is improved, but the complexity of the system increases
Solution Approach 1:
The system divides the complex task of image analysis into separate functional modules: a neural network for element identification, a relationship detection module for identifying connections between elements, and a language model for generating descriptions. This segmentation allows each module to be optimized independently while working together to achieve accurate comprehensive analysis.
Solution Approach 2:
The patent introduces an intermediary relationship detection module that bridges the neural network's element identification and the final natural language description generation. This intermediary layer processes the identified elements and their spatial relationships to create meaningful descriptions, simplifying the overall system architecture while improving accuracy.
2Ease of operation
If real-time alt text generation is implemented for STEM diagrams, then accessibility for blind and low-vision individuals is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary analysis of STEM diagrams by pre-identifying elements and their relationships before generating the final alt text descriptions. This preliminary processing enables faster real-time generation by having the heavy computational tasks completed in advance, reducing the time required for actual description generation.
Solution Approach 2:
The alt text generation system dynamically adjusts its processing based on the complexity of the diagram and user needs. It can provide high-level summaries quickly or generate detailed descriptions on demand, allowing the system to optimize processing time based on the specific accessibility requirements and diagram complexity.
3Loss of information
If comprehensive element identification and relationship mapping is performed, then the quality of natural language descriptions is improved, but the computational resources required increase
Solution Approach 1:
The system applies different levels of analysis to different parts of the diagram based on their importance and complexity. Rather than uniformly processing every element with the same computational intensity, the system identifies key elements and their critical relationships with higher computational resources while using lighter processing for less important elements, optimizing the balance between information completeness and computational resource usage.

AI summary
A method for associating natural language with digital images is provided. The method includes steps of receiving a digitized image; identifying elements in the digitized image as identified elements; associating a contextual label to each element that becomes content for each element; identifying predetermined relationships between the identified elements; describing the content for each element individually and relationships between the elements with a predetermined language; engineering a prompt to be sent to a Language Model (LM); and receiving a response from the LM. Characteristically, the prompt is configured to provide an LM input and instruct the LL regarding a manner and configuration for responding to the LM input.
