Solution Overview

Problem

Existing irrigation systems for potted plants are often complex, unsuitable for retail and home use, and difficult to transport, leading to issues with inadequate watering and root rot due to insufficient control over water distribution.

Innovation Solution

A one-piece tray system with a capillary element and supporting element that allows for controlled watering through capillary action, featuring a tray with a bottom and upstanding peripheral wall, where the capillary element has an upper and lower part with a groove for water transport, and a kit including a plant pot that can be easily assembled and transported.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple-piece irrigation systems are used, then water control capability is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improvewater control capabilityVSAvoidsystem assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate irrigation components (tray, supporting element, capillary element) into a single integrated one-piece structure. This merging maintains the water control functionality of separate pieces while eliminating assembly complexity, allowing the system to be both reliable and easy to operate.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The one-piece tray system performs multiple functions simultaneously: it provides water storage, structural support, and capillary water transport all in a single component. This multi-functionality resolves the contradiction by delivering comprehensive irrigation control without requiring multiple separate pieces to be assembled.

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

2Ease of operation

If one-piece tray system is used, then ease of operation and transport are improved, but manufacturing precision requirements worsen

Engineering Contradiction:
Improveassembly easeVSAvoidintegration precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

While the final product is integrated, the design incorporates distinct functional zones within the one-piece structure (water reservoir area, support legs, capillary channels) that can be manufactured using standard injection molding techniques. This segmented functional design within a unified structure balances manufacturing precision requirements with ease of operation.

Inventive Principle:
Principle #1Segmentation

3Reliability

If capillary element extends above supporting surface, then water distribution control is improved, but device complexity worsens

Engineering Contradiction:
Improvewater distribution controlVSAvoidcapillary structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The capillary element acts as an intermediary between the water reservoir and the plant root zone. By extending above the supporting surface, it provides controlled water delivery without requiring complex pumping or valve systems. The capillary action itself serves as the simple yet effective mechanism for precise water distribution control.

Inventive Principle:
Principle #24Intermediary (Mediator)
