Solution Overview

Problem

Existing floating panel systems for plant cultivation during the second growth phase face challenges with dehydration and overheating, leading to stress in plants, as the roots initially have limited contact with water, requiring frequent top-side watering which can lead to overhydration and pest issues.

Innovation Solution

A floating panel design with through-holes for substrates and air chambers, featuring water-collecting surfaces and barriers that guide water flow along lower support surfaces to ensure efficient water delivery and retention, preventing bypass and allowing controlled watering, while maintaining a microclimate for air roots.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If frequent top-side watering is applied during the second growth phase, then plants receive sufficient water to prevent dehydration and overheating, but the environment becomes overly humid which allows pests to flourish

Engineering Contradiction:
Improveplant hydration stabilityVSAvoidpest proliferation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary water delivery system through the panel structure itself. Water is delivered from below through channels and barriers that control its path, acting as a mediator between the water source and the substrate. This intermediary system ensures water reaches plants without creating excessive surface humidity that attracts pests, while still providing sufficient hydration to prevent dehydration and overheating.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs hydraulic principles by delivering water from below the panel through controlled channels and barriers. The water flow is managed through the panel's internal hydraulic structure, allowing precise control of water delivery to the substrate without over-saturating the surface environment, thus preventing pest proliferation while maintaining plant hydration.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If water is delivered frequently from above, then plants are prevented from dehydrating, but the watering frequency and volume are difficult to control leading to overwatering

Engineering Contradiction:
Improvewater supply adequacyVSAvoidwatering control precision
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a self-regulating water delivery system where the panel structure automatically controls water flow. The barriers and channels guide water along predetermined paths, and the system self-adjusts to deliver appropriate water volumes without requiring external intervention or monitoring, thus preventing both dehydration and overwatering while eliminating the need for manual control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent incorporates feedback mechanisms through the panel's water delivery structure. The barriers and channels provide visual and physical feedback on water flow paths, allowing the system to automatically regulate water distribution. This feedback loop ensures water is delivered adequately to prevent dehydration while preventing overwatering through the structured flow control.

Inventive Principle:
Principle #23Feedback

3Device complexity

If water flow paths are not controlled, then water delivery is simple, but water may bypass the substrate and fail to reach plants effectively

Engineering Contradiction:
Improvewater delivery structureVSAvoidwater delivery effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent divides the water delivery process into segmented sections using barriers and channels within the panel. Instead of a single uncontrolled flow path, water is segmented into controlled sections that guide it systematically toward the substrate. This segmentation ensures water follows effective paths to reach plants while maintaining manageable structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality control by creating different flow characteristics in different regions of the panel. Barriers and channels are strategically positioned to create localized water flow patterns that ensure water reaches specific substrate areas effectively. This localized control of water quality and flow direction improves delivery effectiveness without requiring complex overall system design.

Inventive Principle:
Principle #3Local quality
