Innovation Solution

An installation with mobile trays that support plants, featuring a soaking station with an elevator for root soaking and a cutting station with a movable cutting bar to harvest plant parts without harming the plants, along with a transfer trolley and test station for controlled conditions, allowing for efficient metabolite extraction and plant recultivation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If plants are grown hydroponically and roots are soaked in liquid to extract metabolites, then productivity and substance concentration are improved, but plant viability is compromised and plants cannot be reused

Engineering Contradiction:
Improvemetabolite extraction efficiencyVSAvoidplant viability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The plant is divided into two parts: the root system remains in the hydroponic system for continued growth and metabolite production, while the aerial parts are harvested separately. This segmentation allows the valuable root system to be preserved and reused while still enabling extraction of metabolites from the harvested portions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements periodic harvesting cycles where aerial parts are harvested at specific growth stages while the root system continues to grow and can be reused for multiple cycles. This periodic action maintains plant viability across multiple extraction cycles while consistently producing metabolites.

Inventive Principle:
Principle #19Periodic action

2Quantity of substance

If traditional maceration or distillation methods are used to extract substances, then complete extraction is achieved, but the whole plant is destroyed and productivity is reduced

Engineering Contradiction:
Improvetotal metabolite extractionVSAvoidplant reuse capability
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The invention extracts and removes only the aerial parts of the plant for processing through traditional extraction methods, while leaving the root system intact in the hydroponic system. This selective extraction allows complete metabolite recovery from harvested portions without destroying the entire plant, enabling continued production from the surviving root system.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If industrial-scale plant production is implemented, then productivity increases, but system complexity and difficulty of controlling growth conditions increase

Engineering Contradiction:
Improveindustrial production capacityVSAvoidsystem structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The hydroponic system is designed with universal components that can accommodate multiple plants simultaneously in standardized containers. The root suspension system, nutrient delivery, and harvesting mechanisms are multi-functional, serving both cultivation and extraction purposes across industrial-scale production while maintaining manageable system complexity through standardization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system transitions from traditional soil-based horizontal planting to vertical hydroponic suspension, utilizing the vertical dimension for root growth and nutrient delivery. This dimensional change enables higher plant density and improved space utilization for industrial production while simplifying the cultivation environment through controlled nutrient solutions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Quantity of substance

If complete plant harvesting is performed for substance extraction, then maximum substance yield is obtained, but plant survival is lost and recultivation is impossible

Engineering Contradiction:
Improvetotal active substance yieldVSAvoidplant growth cycle time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The system performs preliminary harvesting of aerial parts at optimal growth stages while the root system remains alive and capable of regrowth. This preliminary action allows extraction of metabolites from harvested portions without waiting for complete plant death or decomposition, significantly reducing the time loss associated with full plant lifecycle waiting periods.

Inventive Principle:
Principle #10Preliminary action
