Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern farming practices face challenges in predicting and applying precise pest control and growth enhancers due to unpredictable environmental factors, leading to unnecessary use of active ingredients, human exposure, and disposal issues with treated seeds.
Innovation Solution
A sowing device with a reservoir, separating device, and application device that applies seed dressing to individual plant materials during free fall, allowing for precise and localized treatment based on environmental data and geolocation, using removable cartridges with computer-readable units for controlled dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-treatment of seeds is performed at a pre-treatment location with storage and transport, then seeds can be treated with active ingredients, but human exposure to active ingredients increases and disposal of leftover treated seeds becomes challenging
Solution Approach 1:
The system performs preliminary identification of pest risks and applies active ingredients directly at the field location before planting, eliminating the need for advance pre-treatment at remote locations. This resolves the contradiction by maintaining pest control effectiveness while eliminating human exposure during transport and storage of treated seeds
Solution Approach 2:
The patent extracts the active ingredient application step from the centralized pre-treatment process and relocates it to the field location where seeds are planted. This separation removes treated seeds from the supply chain, eliminating disposal challenges and human exposure while maintaining treatment effectiveness
2Reliability
If broad-band pre-treatment approaches are employed, then all seeds are treated uniformly, but superfluous active ingredients are used and overdosing occurs
Solution Approach 1:
The system applies different active ingredients or dosages to different seeds based on their specific pest risk profiles and field location requirements. This localized approach maintains comprehensive pest protection coverage while eliminating waste from uniform broad-band treatment
Solution Approach 2:
The system uses environmental data, geolocation, and pest occurrence patterns to dynamically determine which active ingredients and dosages are needed for each seed. This feedback-driven approach prevents both under-treatment and overdosing, optimizing active ingredient usage
3Duration of action of stationary object
If stable seed dressings are used for pre-treatment, then storage and transport are facilitated, but compounds with adverse effects on seedling growth cannot be used due to longer term effects
Solution Approach 1:
The system performs seed treatment immediately before planting at the field location, eliminating the storage and transport phase entirely. This allows use of unstable but effective active ingredients that would otherwise be incompatible with storage, while maintaining treatment effectiveness
Solution Approach 2:
The patent extracts the treatment step from the storage and transport process, applying active ingredients only when seeds are planted. This separation removes the constraint of storage stability requirements, expanding the range of usable active ingredients to include those with adverse long-term effects
