Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If uniform printing parameters are used across the entire sample, then the printing process is simple and fast, but the printing quality and uniformity deteriorate due to inhomogeneous tissue porosity and capillary forces

Engineering Contradiction:
Improveprinting qualityVSAvoidprinting process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies local quality by determining local image parameters (such as local porosity and capillary forces) from image data of different regions of the sample, and using these local parameters to control printing parameters specifically for each region. This ensures that each region receives optimized printing conditions tailored to its unique characteristics, thereby improving printing quality and uniformity across the entire sample.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by making the printing parameters adjustable and adaptable based on real-time image analysis. The printing control device dynamically determines printing parameters (such as droplet size, deposition rate, and pattern) according to the locally determined tissue characteristics, allowing the printing process to adapt to variations in tissue porosity and capillary forces across different regions.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If printing parameters are adjusted based on local image parameters, then printing quality and uniformity improve, but the printing process becomes more complex and time-consuming

Engineering Contradiction:
Improveprinting uniformityVSAvoidprinting process time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing image analysis and determining local image parameters before the actual printing process. This pre-characterization of the sample allows the printing control device to have all necessary information ready, enabling optimized printing parameters to be applied from the beginning without requiring time-consuming adjustments during printing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a digital representation of the sample's physical characteristics through image analysis. The local image parameters derived from the image data serve as a digital model that guides the printing process, allowing the system to replicate the optimal printing strategy without physically measuring or manipulating the tissue during printing.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If image analysis is performed to determine local tissue properties, then printing parameter optimization is enabled, but the overall system complexity and processing requirements increase

Engineering Contradiction:
Improveprinting parameter adaptabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the printing control device to perform multiple functions: it captures images of the sample, analyzes the image data to determine local tissue properties, and controls the printing process based on these properties. This multi-functional approach consolidates what could be separate systems into a single integrated device, reducing overall system complexity while maintaining high adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements feedback by using image analysis results to continuously inform and adjust the printing process. The local image parameters provide real-time information about tissue characteristics, which feeds back to the printing control device to optimize printing parameters dynamically, creating a closed-loop system that adapts to sample variations.

Inventive Principle:
Principle #23Feedback
