Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If light scattering characteristic data of the target object is acquired and used to determine ink formation conditions, then the texture reproduction accuracy is improved, but the measurement and data acquisition complexity increases

Engineering Contradiction:
Improvetexture reproduction accuracyVSAvoidlight scattering characteristic measurement complexity
Core Design Contradiction:
Manufacturing precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies preliminary action by pre-acquiring and storing light scattering characteristic data of the target object, printing layer fluids, and internal scattering members in a database before the actual printing process. This pre-acquired data is then retrieved and used to estimate the printed matter's light scattering characteristics, avoiding the need for complex real-time measurements during printing while maintaining high texture reproduction accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a digital representation (light scattering characteristic data) of the target object's optical properties. Instead of directly measuring and reproducing the physical texture, the system copies the optical characteristics into data form, estimates the printed matter's characteristics from this data, and uses the copied information to guide the printing process, simplifying the measurement complexity while preserving accuracy

Inventive Principle:
Principle #26Copying

2Manufacturing precision

If the light scattering characteristics of the internal scattering member and printing layer fluids are considered in the estimation, then the texture reproduction accuracy is improved, but the device complexity and data processing requirements increase

Engineering Contradiction:

Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the light scattering characteristic estimation into separate components: the internal scattering member's characteristics, the printing layer fluids' characteristics, and their combined effect. Each component's data is acquired and stored separately, then processed independently through the estimation algorithm to determine the final printed matter characteristics, making the complex data processing manageable and systematic

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses composite materials concept by treating the printed matter as a composite system consisting of the internal scattering member and printing layer fluids. The light scattering characteristics of this composite structure are estimated by combining the individual characteristics of its components, allowing accurate texture reproduction while systematically processing the complexity through a unified estimation model

Inventive Principle:

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-acquiring and storing multiple types of light scattering characteristic data (target object, internal scattering member, and various printing layer fluids) in a database before the printing process. This pre-prepared data is quickly retrieved during printing, avoiding time-consuming real-time acquisitions and calculations, thus maintaining high estimation accuracy while reducing processing time

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating digital copies of light scattering characteristic data for multiple components and storing them for rapid access. Instead of repeatedly measuring or calculating the same characteristics during printing, the system copies the pre-acquired data into the estimation process, maintaining measurement precision while significantly reducing data processing time

Inventive Principle:
Principle #26Copying
