Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for protecting cultivated areas from spring frosts, such as vineyards and orchards, are either costly, complex, or ineffective at low temperatures, and fail to adapt to annual variations in frost-affected areas due to their fixed nature and high maintenance requirements.
Innovation Solution
A transportable frost protection module with a compact, adjustable design that generates a propelled air flow using a hot air generator, allowing for easy placement between trees or shrubs, and featuring a rotatable and tiltable fan system powered by an autonomous energy source, enabling flexible operation and adaptation to varying frost patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wind turbines are used to protect cultivated areas from frost, then frost protection effectiveness is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The invention extracts the essential function of frost protection from complex wind turbine systems and implements it through a simple portable module with a heater and fan. The module removes unnecessary complexity while retaining the core capability of generating warm air currents to protect crops from frost.
Solution Approach 2:
The invention replaces expensive, complex wind turbines with an inexpensive, portable module that can be easily deployed and removed. The module uses simple components like heaters and fans that are cost-effective and do not require extensive maintenance infrastructure.
2Ease of manufacture
If wind turbines are placed on the periphery of cultivated plots, then installation is simplified, but protection coverage is reduced due to fixed positioning
Solution Approach 1:
The invention transforms the static peripheral placement of wind turbines into a dynamic system where portable modules can be moved to any location within the cultivated plot. The modules can be positioned according to real-time frost risk assessment, allowing flexible adaptation to varying protection needs across different areas.
Solution Approach 2:
The invention divides the protection system into multiple portable modules that can be independently positioned throughout the cultivated area, replacing the single large peripheral wind turbine structure. This segmentation allows flexible deployment based on specific frost risk zones within the plot.
3Stability of the object's composition
If fixed wind turbines are used, then structural stability is improved, but adaptability to annual variations in frost zones is reduced
Solution Approach 1:
The invention replaces fixed structural stability with dynamic deployability. The portable modules can be set up and taken down as needed, allowing the system to adapt to annual variations in frost zone locations while maintaining operational stability during use through proper module design and deployment procedures.
