Solution Overview
Problem
Conventional plant growing methods face challenges in ensuring adequate water supply, light distribution, fertilizer absorption, and pest/virus prevention, leading to suboptimal plant growth and development.
Innovation Solution
A plant growing device featuring an envelope made of sheet material with planar walls, openings for plant extension, and a water-absorptive plant growing medium containing nutrients, along with flow guide channels and micro-holes for efficient water and nutrient distribution, and pest/virus protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If plants are densely spaced to increase productivity, then land use efficiency is improved, but light reception is insufficient causing poor plant growth
Solution Approach 1:
The envelope structure is segmented with multiple openings distributed across its surface, allowing plants to be spaced closely while still receiving adequate light through multiple access points from different directions
2Ease of manufacture
If fertilizer is applied on the outer layer of soil, then fertilizer application is simple, but fertilizer penetration into soil is insufficient reducing plant absorption
Solution Approach 1:
The envelope incorporates a porous water-absorptive material that creates capillary channels, allowing fertilizer applied on the surface to penetrate deeply into the soil through the porous structure, ensuring reliable plant absorption while maintaining application simplicity
3Adaptability or versatility
If conventional soil is used as growing medium, then material availability is good, but water retention and distribution is insufficient affecting plant growth
Solution Approach 1:
The envelope combines conventional soil with a water-absorptive material to create a composite growing medium that maintains the availability of conventional materials while significantly improving water retention and distribution capabilities for better plant growth
