Green Roof Pocket Insert for Defined Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing green roof and wall components lack an efficient and aesthetically pleasing solution for shaping and supporting the exterior appearance of vegetation pockets, while also facilitating easy installation and transportation.
Innovation Solution
A building component featuring a flexible layer with pockets containing a substrate for vegetation, where each pocket is shaped and supported by an insert comprising a frame that defines the exterior edges and surface of the pocket, enhancing appearance and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If no insert is used to shape the pocket, then the component structure is simpler and easier to manufacture, but the exterior appearance is undefined and the shape is not durable
Solution Approach 1:
The component is divided into separate functional elements: the flexible layer forming the pocket and the insert providing structural shaping. This segmentation allows each element to be optimized independently - the pocket for flexibility and the insert for defined geometry - while together they achieve both appearance and structural integrity.
Solution Approach 2:
The insert is placed inside the pocket, with the pocket containing the substrate and the insert shaping the exterior. This nested arrangement allows the insert to define the desired geometry from the interior, while the flexible layer encapsulates everything and provides the outer protective layer and water impermeability.
2Reliability
If the pocket is closed and sealed, then water retention is improved, but substrate filling becomes difficult
Solution Approach 1:
The pocket is left open at one end during the filling process, allowing efficient substrate insertion. After filling, the open end is closed by folding back the flexible layer and securing it to the insert. This preliminary open state enables easy manufacturing and filling, while the subsequent closing provides the required water retention.
Solution Approach 2:
The pocket transitions from an open state during filling to a closed state for water retention. The flexible layer can be dynamically positioned - open during manufacturing for access, then folded and secured after filling to create the sealed water-retaining environment.
3Quantity of substance
If the pocket is made larger to accommodate more substrate, then vegetation support is improved, but transportation and handling become more difficult
Solution Approach 1:
The green roof system is divided into multiple modular components, each containing a pocket with substrate. This segmentation allows each module to be of manageable size for transportation and handling, while the collective arrangement of multiple modules provides the total required substrate capacity for the vegetation.
Solution Approach 2:
Instead of making single large pockets, the solution uses multiple smaller pockets arranged in patterns on the flexible layer. This dimensional arrangement allows the system to achieve high total substrate capacity while maintaining individual pocket sizes that are easy to handle and transport.

AI summary
The invention relates to a component for assembling a green roof, such as a flat green roof, a substantially flat green roof, or a pitched roof, or a green wall, which component comprises a flexible layer having at least one pocket containing a substrate for vegetation, wherein the pocket further contains an insert that at least in part shapes the exterior appearance of the pocket.
