Solution Overview

Problem

Existing vertical greening systems for buildings are complex, fragile, and require high maintenance due to clogged nozzles and complex assembly processes, making them expensive and difficult to implement extensively without ground constraints.

Innovation Solution

A system using water-absorbent and water-permeable mineral materials with embedded irrigation channels for indirect irrigation, eliminating the need for separate pipes and nozzles, allowing for simple and inexpensive construction and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate pipes and nozzles are used for irrigation, then water can be supplied to plants, but the system becomes complex and fragile with frequent clogging

Engineering Contradiction:
Improveirrigation system reliabilityVSAvoidirrigation system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the separate irrigation pipes and nozzles from the system. Instead of using conventional piping infrastructure, the irrigation function is integrated directly into the building facade material itself, removing the problematic components that cause clogging and complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The irrigation function is merged with the building facade material. The facade material itself serves dual purposes: structural/architectural function and water distribution function. This integration eliminates the need for separate irrigation infrastructure

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If conventional irrigation systems with pipes and nozzles are used, then water supply is achieved, but assembly effort and cost increase

Engineering Contradiction:
Improvesystem construction easeVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The irrigation channels are merged into the building facade elements themselves during manufacturing. This integration means that water distribution infrastructure is built-in rather than installed separately, dramatically simplifying both manufacturing and assembly processes

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The irrigation channels are pre-formed as integral parts of the facade elements during manufacturing. This preliminary integration of irrigation infrastructure into the building components eliminates the need for complex field assembly of separate piping systems

Inventive Principle:
Principle #10Preliminary action

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
