Light String Frost Protection for New Plantings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current frost protection methods for grapevines and new plantings are inadequate in effectively addressing both radiation frost and advection frost, often resulting in damage or loss of new shoots and plantings, especially during prolonged or repeated frost events.
Innovation Solution
A frost protection system utilizing light strings with a high density of lights (at least four per linear meter) powered by a thermal control unit that adjusts energy delivery based on measured temperature, providing targeted infrared radiation to protect new growth and plantings from frost damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water spraying is used to keep new shoots at 0°C, then frost protection is achieved, but significant amount of water is required which is insufficient for longer frosty spells
Solution Approach 1:
The patent changes the protection mechanism from water-based thermal mass to light-based direct heating. By using light strings with specific power density (at least four lights per linear meter), the system directly increases temperature of new shoots without requiring large quantities of water, thus resolving the contradiction between protection reliability and water consumption.
2Reliability
If smudge pots or fans are used for frost protection, then some frost protection is achieved, but few solutions can overcome both radiation frost and advection frost effectively
Solution Approach 1:
The light string system provides universal frost protection against both radiation frost and advection frost. The light strings can be positioned at different heights and densities (at least four lights per linear meter) to address different frost types, making the system versatile enough to handle multiple frost scenarios simultaneously.
Solution Approach 2:
The system applies local quality by positioning light strings at specific densities (at least four lights per linear meter) and heights to create localized warming zones around new shoots. This localized approach allows the system to effectively protect against both radiation frost (through direct infrared heating) and advection frost (through localized temperature elevation).
3Reliability
If light strings with high density are used, then targeted infrared radiation is delivered to protect new growth, but energy consumption increases
Solution Approach 1:
The system uses local quality by concentrating light output at specific locations where new growth occurs. By positioning light strings with at least four lights per linear meter directly over or near the vulnerable new shoots, the system delivers infrared radiation precisely where needed, minimizing wasted energy and reducing overall consumption while maintaining effective protection.

AI summary
A frost protection system for protecting new growth or new plantings from frost includes one or more light strings for irradiating the new growth or new planting to be protected from frost, a power supply for supplying the light strings with electrical power and a thermal control unit for controlling the power supply on the basis of measured temperature. The one or more light strings have at least four lights per linear meter.
