Adhesive membrane used to preserve the fresh cut characteristics of a christmas tree base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trees tend to seal their cut surfaces quickly after being cut, limiting their ability to absorb water, especially when there is a delay between cutting and placing them in a stand, which shortens the lifespan of Christmas trees as many consumers do not want to or cannot re-cut the tree base.
Innovation Solution
A membrane with a high water content hydrogel layer, preferably with adhesive qualities, is attached to the cut end of the tree trunk to prevent sealing and maintain hydration, including a backing layer and a removable release layer to facilitate attachment and water absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fresh cut is made on the tree base before placing it in a stand, then the tree's ability to absorb water is improved, but the complexity of operation increases and consumer convenience deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-cutting the tree base at the point of purchase and immediately applying a water-soluble coating that prevents sealing. This eliminates the need for consumers to perform a second cut, as the coating is already in place to maintain water absorption pathways open during transport and display.
Solution Approach 2:
The water-soluble coating acts as an intermediary substance between the cut tree base and the environment. It prevents the natural sealing process while being designed to dissolve under appropriate conditions (such as exposure to moisture from water reservoirs or rain), thereby maintaining water absorption capability without requiring mechanical re-cutting by consumers.
2Reliability
If the tree is placed in a stand with water immediately after cutting, then water absorption is maintained, but the tree's lifespan is limited when transport delay occurs
Solution Approach 1:
The coating is applied in advance during the cutting and preparation process, creating a protective barrier before the tree undergoes transport delays. This preliminary protection ensures that even if the tree cannot be placed in water immediately, the cutting surfaces remain open and capable of absorption once water becomes available.
Solution Approach 2:
The water-soluble coating provides beforehand cushioning by preventing the sealing process that would otherwise occur during transport delays. It acts as a protective measure that cushions against the harmful effect of time passing without water, maintaining the tree's physiological capability to absorb water when the opportunity arises.
3Reliability
If the cut surface is exposed to air, then the tree compartmentalizes and seals the cut surface, but this sealing prevents water uptake
Solution Approach 1:
The water-soluble coating serves as an intermediary layer between the cut surface and air exposure. It prevents direct contact between air and the cutting surfaces, thereby blocking the triggering mechanism for compartmentalization and sealing, while still allowing the tree to function normally when water is available.
Solution Approach 2:
The patent replaces the mechanical action of re-cutting with a chemical solution approach. Instead of using physical force to remove sealed tissue, the water-soluble coating chemically prevents sealing by maintaining a moist environment that inhibits the biochemical processes leading to compartmentalization and seal formation.
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
The membrane effectively prevents the tree trunk from sealing, allowing for prolonged water uptake and maintaining tree hydration during transport and in the stand, similar to a tree that has received a second cut, extending the tree's lifespan and convenience for consumers.
Implementation Method 1
The hydrogel layer preferably has adhesive qualities to attach to the cut end surface
Implementation Method 2
The hydrogel layer preferably has adhesive qualities to attach to the cut end surface
Implementation Method 3
The membrane may include an adhesive layer adjacent to the hydrogel layer to aid in attachment to the tree

AI summary
A membrane for covering the cut end of a tree trunk to prevent the tree from creating a seal after it has been cut. The membrane is attachable to the cut end surface of the tree trunk and includes a hydrating layer comprising a hydrogel. The hydrogel, made up primarily of water, adheres to the cut end surface of the tree trunk to continue hydrating the tree, and prevents air from reaching the tree's exposed transport tissue. In some embodiments, the membrane includes a backing layer and a release layer on opposite sides of the hydrating layer.
