Solution Overview

Problem

Current 3D printing technologies are unable to form three-dimensional-shaped objects that satisfy the growth environment requirements for plants, as they require moisture and specific growth conditions, making it difficult to cultivate plants using these objects.

Innovation Solution

A three-dimensional shape information generating system and apparatus that create objects with a three-dimensional mesh-like structure suitable for plant growth, allowing for arbitrary outer shapes and improved water and air retention, using materials like plastic resin, silicone, or ceramics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional 3D printing technology is used to form three-dimensional objects, then arbitrary outer shapes can be achieved, but the objects cannot satisfy plant growth environment requirements (moisture retention, air circulation, pH stability)

Engineering Contradiction:
Improveplant growth environment suitabilityVSAvoidgrowth condition satisfaction
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies porous materials by forming a three-dimensional mesh-like structure within the printed object. This mesh structure creates interconnected pores that enable moisture retention through capillary action, allow air circulation for root respiration, and provide surface area for pH-stabilizing materials. The porous structure transforms the solid printed object into a functional growing medium that satisfies plant growth requirements while maintaining the arbitrary outer shape capability of 3D printing.

Inventive Principle:
Principle #31Porous materials

2Strength

If a solid structure is used for 3D printed objects, then structural integrity is maintained, but moisture and air retention for plant growth is insufficient

Engineering Contradiction:
Improvestructural integrityVSAvoidmoisture and air retention capacity
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The patent introduces a porous mesh structure inside the solid printed object. This mesh maintains structural integrity through its three-dimensional framework while creating numerous interconnected pores throughout the volume. These pores trap moisture through capillary forces and retain air for root oxygenation, thus simultaneously preserving strength and increasing moisture/air retention capacity for plant growth.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The patent employs composite materials by combining the printed structural material with pH-stabilizing substances incorporated into the mesh structure. This composite approach allows the object to maintain structural strength from the printed material while the embedded pH-stabilizing components provide chemical buffering capacity, creating a multi-functional material system that satisfies both mechanical and chemical growth requirements.

Inventive Principle:
Principle #40Composite materials
