Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing agricultural methods struggle to automate the process of treating plant propagation materials like seeds and seedlings without damaging the root system or soil medium, while also allowing for selective application of dressing compositions based on environmental conditions.

Innovation Solution

A method and apparatus that uses a separating device to orient plant propagation materials vertically above plant-receiving cavities, applying dressing compositions during their free fall, and a sensor-controlled application device to ensure precise and contamination-free treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical treatments such as hot water, hot air and electron treatment are used to control pathogens, then disease control is improved, but the ability of plant materials to proliferate is affected

Engineering Contradiction:

Improvedisease controlVSAvoidproliferation ability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the treatment parameters by using lower temperatures and shorter exposure times compared to traditional hot water or hot air treatments. The system applies heat, electron beams, or chemical agents in controlled, brief pulses that are sufficient to kill pathogens but gentle enough to preserve seedling viability and proliferation ability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces intermediary substances or methods between the pathogen and the seedling. Chemical agents act as intermediaries to destroy pathogens without directly exposing seedlings to harsh physical conditions. The system uses intermediate treatment chambers that separate the pathogen destruction process from the seedling handling process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If conventional pesticide seed treatments are used, then pathogen control is improved, but operator exposure and contamination risks increase

Engineering Contradiction:

Improvepathogen controlVSAvoidoperator exposure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the pesticide application process from the operator's direct environment. The system uses automated dispensing mechanisms that apply chemical agents through sealed nozzles and conduits, completely separating the operator from contact with pesticides. The treatment chamber is an enclosed system where all chemical applications occur without operator presence.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs self-service by automatically dispensing and applying chemical agents without operator intervention. The automated dispensing mechanism controls the timing, location, and amount of chemical application, eliminating the need for operators to manually handle or apply pesticides to seedlings.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If manual planting methods are used, then operator control is improved, but productivity and efficiency decrease

Engineering Contradiction:

Improveoperator controlVSAvoidplanting efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent creates a universal system that combines multiple functions into a single automated apparatus. The system performs seedling extraction, orientation, treatment application, and placement operations all through one integrated machine, maintaining operational control while dramatically increasing productivity compared to manual methods.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces manual mechanical operations with automated mechanical and electronic systems. Sensors detect seedling positions and orientations, electronic controls coordinate the sequence of operations, and automated mechanisms perform extraction and placement, substituting operator mechanical actions with precisely controlled automated systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Productivity

If seedlings are treated while in seedling trays, then treatment efficiency is improved, but root system damage and contamination increase

Engineering Contradiction:

Improvetreatment efficiencyVSAvoidroot system damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the treatment process into distinct phases: extraction, orientation, treatment application, and placement. By separating the treatment step from the tray environment and applying treatment to individual suspended seedlings rather than seedlings in trays, the system maintains efficiency while preventing root damage and contamination that would occur in tray-based treatment.

Inventive Principle:

Principle #1Segmentation
