Solution Overview

Problem

Existing manufacturing processes, such as additive manufacturing, often fail to optimize build parameters based on intended post-production treatments, leading to suboptimal performance and quality of the final product.

Innovation Solution

A method to determine build parameters during the manufacturing process based on the intended post-manufacture treatment, using data to adjust parameters like the amount and location of printing agents, to ensure the object is manufactured in a way that is suitable for the intended post-production operation, such as mechanical polishing, chemical polishing, or coloring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If build parameters are optimized for additive manufacturing process, then manufacturing efficiency is improved, but quality for post-production treatment deteriorates

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidquality for post-production treatment

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent changes build parameters based on the intended post-production treatment. Different parameters (printing agent amount, layer thickness, heating temperature) are adjusted according to whether the object will undergo mechanical polishing, chemical polishing, or coloring, thereby optimizing both manufacturing efficiency and post-treatment quality.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent applies different build parameters to different regions or objects based on their intended post-production treatment. Objects requiring mechanical polishing receive different parameter settings compared to those requiring chemical polishing or coloring, ensuring each object is optimized for its specific post-treatment requirements.

Inventive Principle:

Principle #3Local quality

2Manufacturing precision

If build parameters are optimized for post-production treatment, then quality is improved, but manufacturing efficiency deteriorates

Engineering Contradiction:

Improvequality for post-production treatmentVSAvoidmanufacturing efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent determines the intended post-production treatment before the additive manufacturing process begins. By knowing the post-treatment requirements in advance, the system can pre-configure appropriate build parameters, eliminating the need for trial-and-error adjustments and ensuring both quality and efficiency from the start.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts build parameters based on the predetermined post-production treatment type, achieving optimal quality outcomes without sacrificing manufacturing efficiency through intelligent parameter selection rather than repeated manufacturing cycles.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If printing agent amount is increased, then coalescence and solidification are improved, but material consumption increases

Engineering Contradiction:

Improvecoalescence and solidificationVSAvoidmaterial consumption

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent adjusts the printing agent amount parameter based on the intended post-production treatment. For objects undergoing mechanical polishing, optimal printing agent amounts are determined that ensure proper coalescence and solidification while minimizing material consumption, rather than using excessive amounts universally.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Different printing agent amounts are applied to different objects or regions based on their specific post-treatment requirements, ensuring each receives the precise amount needed for reliable coalescence and solidification without unnecessary material consumption.

Inventive Principle:

Principle #3Local quality
