Solution Overview

Problem

Traditional manufacturing processes for lighting products, such as injection molding, are costly and inflexible, making it difficult to produce design-centered products with varying consumer tastes and limited production runs without high overhead costs, while 3D printing lacks resources and expertise for mass production of functional components.

Innovation Solution

A method and system that combines 3D-printed parts with standardized functional components, using cloud computing to verify and optimize CAD models for design requirements, allowing for scalable production of custom lighting products without high upfront costs, by integrating 3D printing with pre-fabricated components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional manufacturing processes such as injection molding are used, then manufacturing precision and strength are improved, but device complexity and overhead costs increase

Engineering Contradiction:
Improvemanufacturing precisionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The lighting product is divided into two distinct segments: standardized functional components manufactured through traditional injection molding processes, and custom aesthetic components manufactured through 3D printing. This segmentation allows each part to be optimized for its specific manufacturing requirements, reducing overall device complexity while maintaining precision where needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Standardized functional components are designed with universal interfaces and mounting mechanisms that work across different lighting product designs. This universality allows the same functional components to be reused in various custom aesthetic designs, reducing the need for complex custom tooling while maintaining manufacturing precision.

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

2Reliability

If traditional manufacturing processes are used, then strength and reliability are improved, but adaptability and flexibility worsen

Engineering Contradiction:
ImprovereliabilityVSAvoidadaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

By segmenting the product into standardized functional components and custom aesthetic components, the system achieves both reliability through proven traditional manufacturing for functional parts and adaptability through flexible 3D printing for aesthetic parts. Each segment can be independently optimized for its specific requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system enables dynamic adaptation of the lighting product design by allowing the aesthetic components to be easily modified and reprinted based on consumer tastes and design trends, while the functional components remain standardized for reliability. This dynamic approach allows rapid prototyping and customization without compromising the reliability of core functional elements.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If 3D printing is used for custom components, then adaptability and design flexibility are improved, but manufacturing precision and reliability worsen

Engineering Contradiction:
Improvedesign flexibilityVSAvoidmanufacturing precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The segmentation strategy assigns custom aesthetic components to 3D printing (where design flexibility is paramount) and standardized functional components to traditional manufacturing (where precision is critical). This resolves the contradiction by ensuring each manufacturing method is applied where it excels.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different manufacturing precision requirements are applied locally to different components: high precision is required for functional components with standardized interfaces, while aesthetic components can tolerate greater variability. The local quality principle allows each component to be manufactured with the appropriate level of precision for its specific function.

Inventive Principle:
Principle #3Local quality

4Adaptability or versatility

If 3D printing is used for functional components, then adaptability is improved, but productivity and cost-effectiveness worsen

Engineering Contradiction:
ImproveadaptabilityVSAvoidproductivity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

By segmenting functional components from aesthetic components, the system can mass-produce standardized functional parts through efficient injection molding while only 3D printing the custom aesthetic portions. This dramatically improves productivity for the functional elements while maintaining adaptability for the aesthetic elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Universal standardized functional components can be mass-produced once and reused across multiple lighting product designs, improving productivity through economies of scale. The same functional components serve multiple design configurations, reducing the need for repeated 3D printing of functional elements.

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