Solution Overview
Problem
Existing green roof systems are labor-intensive to install and require complex logistics, with challenges in recycling and uniform substrate distribution, and they often result in labor inefficiencies and risks of substrate spilling during construction.
Innovation Solution
Modular green roof units with a flexible substrate layer fixed to a rigid carrier, allowing for interlocking and easy installation, using biodegradable materials for the flexible layer that decomposes over time, enabling efficient recycling and uniform substrate distribution, and incorporating a drainage system for effective water management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional green roof systems are installed by depositing and spreading substrate and vegetation at the construction site, then the green roof can be assembled, but the installation process becomes labor-intensive and time-consuming
Solution Approach 1:
The green roof system is divided into modular units, each comprising a drainage component, substrate, and vegetation pre-assembled together. This segmentation allows the entire green roof to be constructed by simply placing and interlocking these pre-fabricated modules, dramatically reducing on-site labor and installation time while maintaining system functionality.
Solution Approach 2:
The substrate and vegetation are pre-applied to the drainage component during manufacturing, forming complete modular units before delivery to the construction site. This preliminary action eliminates the need for labor-intensive on-site substrate deposition and vegetation installation, significantly improving installation productivity.
2Loss of substance
If substrate is deposited and spread at the construction site, then the green roof can be assembled, but substrate spilling occurs and labor costs increase
Solution Approach 1:
The substrate is contained within discrete modular units with defined boundaries, preventing it from spreading or spilling during transport and installation. Each module carries its own substrate portion, eliminating the substrate spilling problem entirely while maintaining installation efficiency.
Solution Approach 2:
The substrate is pre-applied and secured to the drainage component during manufacturing, forming a stable assembly before delivery. This preliminary action prevents substrate loss during handling and transport, eliminating spilling while maintaining installation productivity.
3Ease of repair
If non-modular green roof systems are used, then continuous coverage can be achieved, but recycling and disposal become difficult
Solution Approach 1:
The green roof is constructed from discrete modular units that can be easily removed, disassembled, and recycled individually or in groups. This segmentation enables straightforward recycling and reuse of components while the interlocking design of multiple modules maintains continuous green roof coverage across the building surface.
Solution Approach 2:
The modular design allows the same standardized units to serve multiple functions: providing continuous coverage when assembled in large numbers, enabling easy recycling when removed, and allowing selective replacement of individual modules for maintenance or repair, thus achieving both continuity and recyclability.
4Manufacturing precision
If substrate is manually distributed at the construction site, then coverage can be achieved, but uniform distribution is difficult to accomplish
Solution Approach 1:
The substrate is pre-distributed in controlled, uniform portions within each modular unit during manufacturing. This segmentation ensures that each module contains a precise, uniform amount of substrate, which is then simply placed on the roof without requiring manual distribution, achieving both uniformity and installation simplicity.
Solution Approach 2:
The substrate is pre-applied and evenly distributed across the drainage component during manufacturing under controlled conditions. This preliminary action ensures uniform substrate distribution within each module before delivery, eliminating the need for difficult manual distribution work at the construction site.
