Plant Stem Hole for Direct Xylem Substance Introduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for introducing substances into plants are complex, inefficient, and can damage the plant or reduce its lifespan, as they often require large and cumbersome equipment, risk stem damage, or have low absorption efficiency.
Innovation Solution
A method involving forming a final hole in the plant stem with a larger internal dimension parallel to the stem's longitudinal axis, allowing easier substance absorption and minimizing damage, which can be achieved through drilling, cutting, or using a hypodermic needle to create and enlarge the hole, and then sealing it to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hollow spikes with transverse passageways are pressed into the plant stem, then substance introduction is achieved, but the system becomes complex and fabrication/positioning becomes difficult
Solution Approach 1:
The patent extracts the complex hollow spike structure with transverse passageways and replaces it with a simple probe that creates a direct opening into the xylem. The substance introduction function is maintained while eliminating the complex fabrication and positioning requirements of the hollow spike system.
Solution Approach 2:
Instead of using a complex hollow spike that requires precise positioning and fabrication, the patent inverts the approach by using a simple probe to create an opening, allowing the plant's own xylem system to guide substance transport. This reverses the complexity from the introduction device to the natural plant physiology.
2Reliability
If an unpressurized reservoir with probes is used, then substance introduction is achieved, but the construction becomes large requiring additional mounting aids
Solution Approach 1:
The patent extracts and eliminates the large unpressurized reservoir and mounting aid system. Instead, substance is introduced directly through a probe into the xylem, where capillary action and transpiration pull naturally draw the substance upward without requiring large storage containers or complex mounting structures.
Solution Approach 2:
The plant's own xylem system provides the mechanism for substance transport through capillary action and transpiration pull, eliminating the need for external reservoirs and mounting aids. The plant essentially services itself by drawing substances up through its natural physiological processes.
3Productivity
If probes or needles remain connected to the stem during substance introduction, then continuous substance delivery is achieved, but the risk of stem damage increases due to sharp tips
Solution Approach 1:
The probe is carefully inserted to create a precise opening into the xylem before substance introduction begins. This preliminary action ensures proper positioning that minimizes damage to surrounding stem tissue while establishing a functional connection for continuous substance delivery.
Solution Approach 2:
The probe creates a localized opening specifically into the xylem tissue, concentrating the interaction at the precise location needed for substance introduction. This localized approach minimizes damage to other parts of the stem while maintaining continuous substance delivery through the targeted xylem entry point.
4Reliability
If roots are physically injured and brought into contact with fluid, then substance absorption is achieved, but the plant is severely injured with risk of death and the method becomes laborious
Solution Approach 1:
Instead of injuring the roots and relying on fluid contact for absorption, the patent inverts the approach by introducing substance directly into the xylem system through the stem. This allows substance delivery without root injury, eliminating the laborious steps of removing the plant from soil and the severe injury risks to the root system.
Solution Approach 2:
The patent extracts the substance introduction point from the root system and relocates it to the stem xylem. This eliminates the need for root injury and the associated laborious procedures, while maintaining effective substance absorption through the intact root-xylem connection.
5Reliability
If a hole is made into the stem to receive a pipette, then substance introduction is achieved, but fixing the pipette without leakage becomes difficult
Solution Approach 1:
The patent extracts the pipette fixation problem by replacing it with a probe that creates a direct opening into the xylem. The probe design inherently provides a secure connection point that eliminates the leakage issues associated with trying to fix a pipette to the stem surface.
Solution Approach 2:
The probe serves multiple functions: it creates the opening, provides a secure connection point for substance introduction, and utilizes the plant's natural xylem system for substance transport. This multi-functionality eliminates the need for separate fixation mechanisms required by pipette-based methods.
6Reliability
If the plant is watered with substance-containing fluid, then substance absorption is achieved, but efficiency is very low as multiple times the required amount must be introduced into the soil
Solution Approach 1:
The patent extracts the substance from the bulk soil watering approach and delivers it directly to the xylem system through a probe. This targeted delivery eliminates the need to introduce multiple times the required amount into the soil, dramatically improving introduction efficiency while maintaining absorption effectiveness.
Solution Approach 2:
The probe delivers substance locally directly into the xylem at a specific location in the stem, rather than distributing it broadly through soil watering. This localized delivery ensures that the substance is immediately available for uptake without requiring large quantities to be introduced into the surrounding soil environment.
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
This method enhances substance absorption by increasing the internal surface area of the stem, reduces the risk of air bubble blockage, and allows for easier closure of the hole, thereby improving the plant's health and longevity.
Implementation Method 1
Any fluid inside the reservoir is then taken up by the plant using the transpiration pull of the xylem system
Implementation Method 2
subjecting the interior of the final hole to the substance by introducing the substance through the opening

AI summary
A plant, in particular a Phalaenopsis orchid, provided with a hole into its stem, wherein the hole is accessible via an opening in an outer surface of the stem, wherein the hole allows the interior of the stem to be exposed to a substance entering the plant via the opening so that the substance can enter the interior of the stem, wherein the hole has a dimension in a direction parallel to a longitudinal axis of the stem which is larger than a maximum dimension of the opening providing access to the hole in the direction parallel to the longitudinal axis of the stem, and wherein the diameter of the opening is above 2 mm, wherein in the longitudinal direction of the stem of the plant, the hole extends in a direction away from the roots of the plant and also in a direction towards the roots of the plant.
