Mobile Greenhouse Frame with Adjustable Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile agricultural devices, such as mobile greenhouses and poultry houses, face challenges like soil over-fertilization leading to groundwater pollution, inability to operate on uneven terrain, and lack of protection from all sides, which disrupt ecological balance and soil nutrient regulation.
Innovation Solution
A mobile agricultural device with a frame device that allows for a bottomless greenhouse to be positioned directly on agricultural land, featuring a large support surface, adjustable wheel unit, and runners for easy movement and distribution of load, ensuring the greenhouse can be used on nutrient-rich and over-fertilized soil without sinking, and promoting ecological balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the mobile agricultural device uses small wheels to position the greenhouse close to the grass, then the greenhouse can be positioned near the ground, but the wheels become stuck in wet, waterlogged ground rendering the greenhouse immobile
Solution Approach 1:
The patent employs adjustable wheel units that can be raised and lowered dynamically. During transport, wheels are lowered to enable movement; during operation on wet or uneven ground, wheels are raised to prevent the device from becoming stuck, thus adapting to different operational conditions and maintaining reliability
Solution Approach 2:
The patent introduces vertical adjustability of the wheel units, adding a dimensional degree of freedom. The wheel units can be positioned at different heights relative to the ground, allowing the device to transition between ground-contact mode for transport and elevated mode for stable operation on problematic terrain
2Stability of the object's composition
If the mobile protective tunnel stands on wheels raised a considerable distance from the ground, then the tunnel structure is stable, but it offers no protection from below or from the sides
Solution Approach 1:
The patent employs flexible side walls made of protective film material that can be extended downward from the greenhouse structure. These flexible barriers provide protection from side hazards while maintaining the stable elevated wheel configuration, creating a comprehensive protective envelope around the plants
3Ease of manufacture
If mobile greenhouses have a continuous concrete floor for cultivation, then plants can be grown on the floor, but the greenhouses cannot be used for growing plants on existing agricultural land
Solution Approach 1:
The patent extracts the cultivation function from a permanent concrete floor structure and relocates it to movable planting containers or modular planting units. These can be placed on the ground-level frame structure, allowing the greenhouse to utilize existing agricultural land while maintaining cultivation capabilities through removable planting systems
Solution Approach 2:
The patent divides the cultivation system into separate modular components: the frame structure, the greenhouse enclosure, and the planting containers. This segmentation allows the planting containers to be independently positioned on existing agricultural land rather than requiring an integrated concrete floor, enhancing adaptability to different land types
4Reliability
If the frame structure provides a large bearing surface to distribute load across cultivated soil, then the device can operate on unpaved and freshly plowed land without sinking, but the structure complexity increases
Solution Approach 1:
The frame structure is divided into multiple modular frame assemblies, each with its own bearing surface elements. This segmentation allows the complex load-distribution function to be achieved through repetition of simpler modular units rather than a single complex structure, making the system more manageable and adaptable
