Solution Overview

Problem

Existing text-to-image models struggle to generate photo-realistic objects of mixed concepts that are highly dissimilar, often dominating one concept over the other, especially when blending imaginary scenes or objects that do not exist in the real world.

Innovation Solution

A method using a pre-trained text-to-image diffusion-based generative model that synthesizes an output object by generating a layout from a first input and injecting a content conditioner into the layout, followed by a de-noising process to generate the object's content, effectively blending highly dissimilar concepts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If prompt interpolation is used to blend two text prompts in latent space, then the generated image can combine two concepts, but when the concepts are extremely dissimilar (e.g., living object and non-living object), the generated image is dominated by one concept

Engineering Contradiction:
Improveability to blend dissimilar conceptsVSAvoidbalance between mixed concepts
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent segments the image generation process into two distinct phases: layout generation (from first prompt) and content injection (from second prompt). This segmentation allows each prompt to contribute separately to different aspects of the final image, preventing one concept from dominating the other while maintaining their distinct identities in the composite output.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent moves from blending concepts in the text latent space (one-dimensional prompt interpolation) to blending them in the image generation process across multiple dimensions: structural layout, semantic content, and visual features. This dimensional expansion enables better control over how dissimilar concepts are combined, allowing both concepts to coexist with appropriate balance.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If existing text-to-image models generate objects of mixed concepts, then they can create composite images, but the objects lack photo-realism when the concepts are highly dissimilar

Engineering Contradiction:
Improveability to generate mixed concept objectsVSAvoidphoto-realism quality
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent performs preliminary layout generation from the first prompt before injecting content from the second prompt. This preliminary action establishes a structurally sound foundation that guides the subsequent content injection, ensuring the final composite object maintains photo-realistic properties while incorporating both concepts accurately.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses the generated layout as an intermediary between the two input prompts. This intermediary structure receives the structural information from the first prompt and the semantic content from the second prompt, mediating their combination in a way that preserves photo-realism while achieving concept blending.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If style transfer is used to combine two images, then the output retains core elements of the first image, but the process cannot create truly new mixed concept objects

Engineering Contradiction:
Improvesimplicity of image combinationVSAvoidability to create new mixed concepts
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent employs a dynamic two-stage generation process where the first stage creates a layout based on the first prompt, and the second stage injects content from the second prompt. This dynamic approach allows the system to adapt to different prompt combinations and create genuinely new mixed concept objects rather than simply transferring styles, while maintaining operational simplicity.

Inventive Principle:
Principle #15Dynamics

AI summary

Generating an object using a diffusion model includes obtaining a first input and a second input, and synthesizing an output object from the first input and the second input. The synthesizing of the output object includes generating a layout of the output object from the first input, injecting the second input as a content conditioner to the layout of the output object, and de-noising the layout of the output object injected with the content conditioner to generate a content of the output object.
