Solution Overview

Problem

Existing 3D printing planning systems fail to efficiently prioritize and optimize the manufacturing of spare parts due to limited resources and incompatibilities, leading to impractical and costly manufacturing processes.

Innovation Solution

A computer-implemented method for 3D printing planning that determines an optimal subset of spare parts to be manufactured by optimizing objective manufacturing functions under 3D printing constraints, considering both factory capacity and spare part compatibility, while allowing user intervention for flexibility and transparency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If all spare parts are manufactured using 3D printing, then manufacturing flexibility and customization are improved, but resource constraints and manufacturing costs increase

Engineering Contradiction:
Improvemanufacturing flexibilityVSAvoidresource consumption
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system determines an optimal subset of spare parts to be manufactured by 3D printing rather than manufacturing all parts. This partial action approach selects only those parts that provide the most value given resource constraints, balancing manufacturing flexibility with resource consumption by optimizing the portfolio of parts produced additively.

Inventive Principle:
Principle #16Partial or excessive action

2Reliability

If 3D printing constraints are strictly enforced, then manufacturing feasibility is improved, but the range of manufacturable spare parts decreases

Engineering Contradiction:
Improvemanufacturing feasibilityVSAvoidspare part compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system evaluates spare parts against 3D printing constraints (build volume, material type, geometric complexity) and determines an optimal subset that satisfies these parameter requirements. By changing the parameters of part selection based on constraint satisfaction, the system maintains manufacturing feasibility while maximizing the range of compatible spare parts through optimized portfolio selection.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If manual evaluation of spare part compatibility is used, then flexibility in decision-making is improved, but processing time and labor costs increase

Engineering Contradiction:
Improvedecision flexibilityVSAvoidprocessing time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system automatically evaluates spare parts against 3D printing constraints and manufacturing objectives, providing feedback on compatibility and optimality. This automated feedback loop replaces manual evaluation, reducing processing time while maintaining decision flexibility through configurable objectives and constraints that reflect user preferences and industrial requirements.

Inventive Principle:
Principle #23Feedback

4Ease of manufacture

If 3D printing is used for all spare parts, then traditional manufacturing limitations are overcome, but environmental impact and energy consumption increase

Engineering Contradiction:
Improvemanufacturing capabilityVSAvoidcarbon footprint
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The system optimizes the selection of spare parts for 3D printing based on manufacturing objectives that include environmental considerations. By changing the selection parameters to prioritize parts where additive manufacturing provides the greatest benefit relative to environmental impact, the system overcomes traditional manufacturing limitations for critical parts while minimizing overall carbon footprint through selective application of 3D printing.

Inventive Principle:
Principle #35Parameter changes
