Greenhouse Ventilation Recesses and Closing Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor greenhouses face challenges in regulating air circulation efficiently, leading to increased susceptibility to faults and energy imbalance, as traditional methods like exhaust fans can be complex and unreliable.
Innovation Solution
The design incorporates recesses in side and door elements with corresponding larger closing elements, allowing for flexible and adjustable air flow without the need for additional fastening measures, with circular recesses and closing elements optimizing air supply and removal, and optional mesh materials for pest prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an exhaust fan is installed to create a chimney effect for air circulation, then air circulation is improved, but device complexity and susceptibility to faults increase
Solution Approach 1:
The patent removes the exhaust fan component entirely and replaces it with passive ventilation openings in the door element. Air circulation is achieved through natural convection and pressure differentials rather than mechanical forcing, eliminating the need for complex mechanical parts while maintaining the air circulation function.
Solution Approach 2:
The ventilation system operates autonomously using natural physical phenomena (buoyancy, pressure gradients) without requiring external power sources or control mechanisms. The openings in the door element allow air to flow through the greenhouse automatically based on environmental conditions, making the system self-regulating and fault-resistant.
2Reliability
If traditional fastening measures like Velcro are used to close door elements, then airtightness is improved, but device complexity increases
Solution Approach 1:
The patent eliminates Velcro fasteners and other traditional closing mechanisms from the door element. Instead, the door is designed with integrated openings that can be simply opened or closed without additional fastening components, reducing complexity while maintaining adequate sealing through the basic door structure and frame.
Solution Approach 2:
Rather than adding complex fastening mechanisms to achieve airtightness, the patent inverts the approach by designing the door element with intentional openings for ventilation and relying on the simplicity of opening/closing the door itself to control air flow, accepting that perfect airtightness is not necessary for proper greenhouse function.
3Productivity
If fixed ventilation openings are provided in door elements, then air supply is improved, but adaptability to different plant needs worsens
Solution Approach 1:
The door element is designed to be movable and adjustable, allowing the user to open or close the door to different degrees based on plant requirements. This dynamic control mechanism enables the ventilation openings to be adjusted in real-time, providing adaptability to different growth stages and environmental conditions while maintaining effective air supply.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables simple, effective, and adjustable air supply and ventilation, improving air circulation and energy efficiency while maintaining airtightness without complex tools or fasteners, and allows for fine regulation of air flow based on plant needs.
Implementation Method 1
two closing elements correspond to the recess in such a way that they are adapted in shape and size to the recess and are designed larger than the recess... enables simple, effective, and adjustable air supply and ventilation, improving air circulation
Implementation Method 2
Both of the recesses can be used flexibly as passive air inlets or outlets, and they can close the indoor greenhouse airtight... Depending on the air flow, both of the recesses can perform both of the functions mentioned without distinction

AI summary
The invention relates to a room greenhouse whose frame is formed from poles (3) connected by corresponding connecting pieces (5), and which has a substantially light- and air-impermeable covering (7) and a base element. The covering (7) forms ceiling (11), side (9), and door elements (13). At least one of the side (9) and/or door elements (13) has a circular recess (17) to which two locking elements (19, 19') correspond. These locking elements are adapted to the shape and size of the recess (17) but are larger than it. The two locking elements (19, 19') assigned to each recess (17) are arranged once on the inside of the respective side (9) and/or door element (13) and once on its outside. Adjacent to the respective recess (17) are circumferential seams (21) on the inside and outside, for fastening the locking elements (19, 19') by inserting them into the seams (21).
