Solution Overview

Problem

Directly planting trees in urban areas can damage infrastructure due to root systems, and maintaining adequate watering is difficult in unsealed street or square areas, requiring complex systems and frequent watering.

Innovation Solution

A plant container with an inner chamber for water storage and an outer chamber for plants, separated by a circumferential wall, allowing for a large water supply and autonomous irrigation, using rainwater collection and a substrate system to support plant growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If trees are directly planted in urban areas, then plant growth is supported, but infrastructure damage occurs due to root systems

Engineering Contradiction:
Improveplant growthVSAvoidinfrastructure damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The planting system is segmented into distinct compartments: an outer container for the plant, an inner water reservoir, and a bottom chamber for substrate. This segmentation allows roots to grow in the substrate chamber while being physically separated from infrastructure, preventing damage while maintaining plant growth.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If concrete planters are used to protect infrastructure, then infrastructure damage is prevented, but maintenance complexity and watering system complexity increase

Engineering Contradiction:
Improveinfrastructure protectionVSAvoidwatering system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The water reservoir and planting container are merged into a single integrated unit where the inner container holds water and the outer container holds the plant. This merging eliminates the need for separate complex watering systems while providing automatic irrigation through the substrate saturation zone.

Inventive Principle:
Principle #5Merging (Combining)

3Quantity of substance

If the space between inner and outer containers is sealed, then a water reservoir is formed, but the reservoir volume becomes small requiring a larger inner container

Engineering Contradiction:
Improvewater storage volumeVSAvoidinner container volume
Core Design Contradiction:
Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The design transitions from a two-chamber system to a three-chamber system by adding the bottom chamber dimension. Water is stored in both the inner container and the bottom chamber, effectively increasing total water storage volume without requiring a larger inner container, as water is distributed across multiple spatial dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Reliability

If frequent external watering is provided, then plant hydration is maintained, but time and resource consumption increase

Engineering Contradiction:
Improveplant hydrationVSAvoidwatering frequency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system provides self-service irrigation through capillary action. The substrate in the bottom chamber automatically absorbs and transports water from the water reservoir to the plant roots, maintaining hydration without requiring external intervention or frequent manual watering.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The plant container provides long-term self-sufficiency for plant watering, reduces maintenance needs, and prevents infrastructure damage by allowing roots to be separated from the water reservoir, ensuring healthy plant growth without frequent external watering.

Implementation Method 1

The bottom chamber is connected to the outer chamber and to the inner chamber. The outer chamber and the inner chamber can communicate with each other via the bottom chamber.

Methodology Applied
Scientific EffectCapillary action: Capillary Action

Implementation Method 2

The plant container can hold a large water supply compared to known plant containers... Water can be supplied to the inner chamber, for example, via its top.

Methodology Applied
Scientific EffectGravity-driven flow: Gravitation
