Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for combating mildew in plants, such as powdery mildew and Downey mildew, rely heavily on chemical fungicides, which pose safety risks and environmental concerns, and existing ultraviolet light treatments often use mercury lamps with limited effectiveness.
Innovation Solution
A system utilizing ultraviolet sources emitting radiation in the range of 260 to 310 nanometers, coupled with sensors to detect mildew presence and a control system for targeted ultraviolet treatment, to effectively combat mildew without the need for chemical fungicides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical fungicides are used to combat mildew, then mildew control effectiveness is improved, but safety risks and environmental harm increase
Solution Approach 1:
The patent replaces chemical fungicide application systems with a physical ultraviolet light-based system. Sensors detect mildew presence and trigger UV light sources to treat affected areas, substituting chemical intervention with a physical radiation-based approach that eliminates harmful chemical exposure while maintaining mildew control effectiveness
Solution Approach 2:
The patent introduces sensors and control systems as intermediaries between mildew detection and treatment. The sensor system detects mildew and activates UV light sources only when needed, creating a targeted response system that avoids blanket chemical application and reduces overall chemical usage while maintaining effective mildew management
2Area of stationary object
If broad coverage spraying techniques are used to apply fungicides, then mildew control coverage is improved, but chemical exposure and safety precautions increase
Solution Approach 1:
The patent implements localized treatment by using sensors to identify specific areas with mildew and directing UV light treatment only to those affected zones. This replaces broad coverage chemical spraying with targeted local treatment, maintaining effective coverage of infected areas while eliminating unnecessary chemical exposure in healthy regions
Solution Approach 2:
The patent applies treatment only to the extent necessary - using sensor detection to activate UV light sources only when and where mildew is present. This partial action approach replaces excessive broad-spectrum chemical application with precise, demand-based treatment that maintains coverage effectiveness while minimizing chemical usage
3Ease of manufacture
If existing ultraviolet mercury lamps are used to treat mildew, then mildew treatment capability is provided, but treatment effectiveness is limited
Solution Approach 1:
The patent changes the wavelength parameter of ultraviolet radiation from the conventional 254 nanometers emitted by mercury lamps to a targeted range of 260-310 nanometers. This parameter change optimizes the radiation's ability to harm mildew while maintaining ease of implementation, thereby improving treatment effectiveness without sacrificing manufacturability
