Solution Overview

Problem

Existing methods for applying systemic and nutritional products to trees and Palmaceae often result in damage to the trunk due to repeated perforations, leading to infection risks and environmental concerns.

Innovation Solution

A modular, easy-to-install plastic cannula system with lateral orifices and spurs that facilitates product distribution and secure placement, minimizing trunk damage and infection risks through a residue-free perforation mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If repeated perforations are made on the trunk for repeated applications, then the product application can be performed multiple times, but the trunk is damaged and becomes vulnerable to infections

Engineering Contradiction:

Improverepeated application capabilityVSAvoidtrunk damage and infection risk

Core Design Contradiction:

Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The injection pick is divided into separate components: a reusable body and a disposable cannula. The cannula is replaced after each use, allowing repeated applications without making repeated perforations to the same trunk location. The trunk is perforated once, and the cannula is simply replaced in the same hole for subsequent applications.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cannula is designed as a disposable, low-cost component that is discarded after a single use. This eliminates the need to repeatedly damage the trunk by creating new perforations, as the disposable cannula can be easily replaced in the existing hole without compromising tree health.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Ease of manufacture

If a drill is used to make perforation and subsequently seal it, then the treatment can be applied, but the plant remains damaged and at risk of infection

Engineering Contradiction:

Improveapplication processVSAvoidinfection risk

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The harmful drilling operation is extracted and replaced by a simple insertion process. The pre-made cannula is inserted into a single perforation without requiring complex drilling equipment or subsequent sealing operations, eliminating the infection risk associated with open wounds.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The cannula is pre-formed with its complete structure including the injection mechanism before insertion. This eliminates the need for on-site drilling and sealing operations, as the cannula is ready for immediate insertion and use, reducing the time the trunk is vulnerable.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If an awl is used to make extraction scratches and remove bark, then the treatment can be applied, but the tree is vulnerable to new infections

Engineering Contradiction:

Improvetreatment applicationVSAvoidinfection vulnerability

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cannula serves as a disposable insertion tool that creates minimal damage. After use, it is discarded rather than reused, preventing the propagation of contaminants that would occur with repeated use of the same tool on the same tree.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

4Duration of action of moving object

If traditional systems are used for repeated applications, then treatments can be applied, but the costs are higher and environmental protection is compromised

Engineering Contradiction:

Improverepeated application capabilityVSAvoidenvironmental impact and cost

Core Design Contradiction:

Duration of action of moving objectVSObject-generated harmful factors

Solution Approach 1:

By separating the reusable injection mechanism from the disposable cannula, the system minimizes waste. Only the small cannula portion needs to be discarded after each use, rather than disposing of entire tools or equipment, reducing environmental impact and operational costs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reusable injection pick body is retained and reused for multiple applications, while only the consumable cannula is discarded. This recovery and reuse of the main device reduces both costs and environmental impact compared to traditional single-use or complex reusable systems.

Inventive Principle:

Principle #34Discarding and recovering

AI summary

The invention relates to an injection pick for dosing systemic and nutritional products into trees and Palmaceae. The invention is characterised in that, once installed in the trunk, it can repeatedly dose any type of systemic or nutritional product in an environmentally friendly manner. The invention comprises an easy-to-install plastic cannula formed by four interconnected parts and the design thereof allows the selected nutritional product or systemic insecticide to be easily applied, preventing continued wounds that could damage the trunk or stem of the plant. The invention comprises the following elements: pick, cover, latch and key.
