Solution Overview

Problem

Current additive manufacturing systems face high rejection rates due to the complexity of setting control parameter values, leading to suboptimal material properties and inefficient production processes, which require frequent manual adjustments and interruptions.

Innovation Solution

A peer-to-peer application is used to optimize control data sets through an optimizing process, reducing the need for central instances and enhancing security, efficiency, and material properties by allowing nodes in a peer-to-peer network to monitor and execute the controlling means, thereby reducing transaction costs and managing complexity.

VSEngineering Contradiction Analysis

1Productivity

If manual adjustment of control parameters is used, then production flexibility is maintained, but productivity decreases and rejection rate increases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidmanual adjustment requirement
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The system performs self-optimization of control parameters through automated feedback loops. The controlling means automatically adjusts control parameter values based on monitored component parameters without requiring manual operator intervention, enabling the system to service itself and eliminate productivity losses from manual adjustments

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements continuous feedback mechanisms where component parameters are monitored during production and fed back to the controlling means. This feedback loop enables automatic recalculation and adjustment of control parameter values to maintain optimal production conditions and reduce rejection rates

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If multiple control parameter values are set manually, then production flexibility is maintained, but manufacturing precision decreases

Engineering Contradiction:

Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system replaces manual mechanical adjustment of control parameters with automated computational processes. The controlling means uses algorithms to calculate optimal control parameter values based on design plans and monitored component parameters, substituting human operator judgment with systematic computational optimization to improve manufacturing precision

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system dynamically changes control parameter values based on real-time component parameters and production conditions. The controlling means automatically recalculates and adjusts multiple control parameters simultaneously to maintain optimal manufacturing precision throughout the production process

Inventive Principle:
Principle #35Parameter changes

3Reliability

If central platform is used for process management, then control capability is maintained, but transaction costs increase and security decreases

Engineering Contradiction:
Improvedata securityVSAvoidcentral platform requirement
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the process management functionality into distributed controlling means that operate autonomously at different production locations. Each controlling means manages its own optimization processes independently, eliminating the need for a centralized platform and reducing transaction costs while maintaining control capability through decentralized architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses standardized communication protocols and data formats as intermediaries between distributed controlling means. This intermediary layer enables seamless coordination and information exchange between decentralized units without requiring a central platform, maintaining system coherence while enhancing security and reducing complexity

Inventive Principle:
Principle #24Intermediary (Mediator)
