Compostable Tree Sheath With Detachable Folded Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tree covers are not suitable for both packaging and disposal, leading to increased costs and environmental impact due to separate disposal methods, and are not easily reusable.
Innovation Solution
A flexible, compostable cover with a detachable connection and adjustable circumference, made from materials like Ecoflex, allowing for easy folding and reuse for both packaging and disposal, including the option for biogas production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a generic cover is used for packaging trees before use, then the tree is protected and volume is reduced, but the cover is not suitable for disposal after use
Solution Approach 1:
The cover is designed to perform multiple functions: it can be used for packaging trees before use and for disposing of trees after use. The openable and closable design along a surface line enables the cover to adapt to different usage scenarios, making a single cover suitable for both packaging and disposal purposes.
2Adaptability or versatility
If a cover is designed for disposal only, then it can be used after tree use, but it increases costs and disposal requirements
Solution Approach 1:
The cover is designed to perform multiple functions: it can be used for packaging trees before use and for disposing of trees after use. The openable and closable design along a surface line enables the cover to adapt to different usage scenarios, making a single cover suitable for both packaging and disposal purposes.
3Object-affected harmful factors
If the cover is made of compostable material, then environmental friendliness is improved, but manufacturing complexity increases
Solution Approach 1:
The cover is made of compostable material such as Ecoflex, which is a bioplastic that can be composted industrially. This material choice changes the physical and chemical parameters of the cover to enable composting, thereby reducing environmental impact. The material can be used for both packaging and disposal purposes.

AI summary
The covering has a tubular section (1) made of laminar material e.g. foil or fabric. The tubular section is folded such that the tubular section forms a cylindrical circumferential part (2) and a fold (3). A detachable connection is provided between longitudinal points of a circumference of the tubular section spaced at a distance from each other, where the longitudinal points form the circumferential part. The circumferential part bridges the fold, where the fold is formed over length of the tubular section. The detachable connection extends over an entire length of the circumferential part.
