Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing green wall systems face challenges with easy installation, removal, and maintenance, as well as optimal water delivery and drainage, leading to issues like water pooling and root rot.
Innovation Solution
A plant propagation and display tray system with interlocking trays featuring alternating projections and troughs that incline towards the back wall, allowing for secure pot placement and controlled water delivery, preventing pooling and promoting healthy plant growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional green wall panels are fixedly secured to building surfaces, then structural stability is improved, but ease of maintenance and plant replacement deteriorates
Solution Approach 1:
The green wall system is divided into discrete modular trays that can be independently handled, installed, and maintained. Each tray functions as an independent unit containing plants, allowing maintenance workers to access and replace individual trays without dismantling the entire green wall structure, thus maintaining structural stability while enabling easy maintenance.
Solution Approach 2:
The system transitions from fixed permanent installation to a dynamic modular configuration where trays can be easily inserted and removed. The trays are designed to be temporarily secured during installation but can be quickly detached for maintenance, allowing the system to adapt between stable installation and easy maintenance states.
2Productivity
If water is delivered to plants in green wall systems, then plant growth is improved, but water pooling and root rot occur
Solution Approach 1:
The tray bottom is designed with differentiated local qualities: elevated central regions that provide drainage pathways and lower peripheral regions that contain water. This local variation in elevation and function allows water to be delivered to plants while preventing harmful pooling at critical locations, promoting healthy root zones.
Solution Approach 2:
The solution adds a vertical dimension to water management by creating elevated drainage pathways and tiered bottom surfaces. Instead of flat water delivery, the system uses multi-level elevation changes to guide water flow, allowing excess water to drain away from plant roots through raised channels while maintaining adequate moisture delivery.
3Strength
If permanent panel structures are used for green walls, then structural integrity is improved, but ease of installation and removal deteriorates
Solution Approach 1:
The green wall system is segmented into standardized modular trays that can be manufactured independently and then assembled into the final structure. This segmentation allows for simplified manufacturing of individual components while maintaining the overall structural integrity of the complete green wall installation through systematic assembly of the modular units.

AI summary
A plant propagation and display tray, capable of interlocking alignment with at least one other tray and capable of receiving and holding at least one plant pot, comprises a back wall and a bottom ledge forwardly projecting from said back wall. The ledge is inclined towards the back wall and comprises alternating projections and troughs, each trough inclining towards a trough point of abutment with the back wall and being of a conformation to securably hold one plant pot such that an open proximal end of the pot is exposed to view and a distal end of the pot is adjacent to the back wall. Each projection has an upper surface inclining towards a projection point of abutment with the back wall. The projection point of abutment is higher than the trough point of abutment with the back wall. The tray is capable of being attached to a wall surface.
