Greenhouse Table Profile Clamping Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cultivation and transport tables in greenhouses face issues with screw connections loosening under heavy forces, leading to instability and potential damage, and require significant storage space when not in use.
Innovation Solution
A method of constructing cultivation and transport tables using separate profiles with a clamping connection and a secondary connecting element, allowing for easy assembly and disassembly, providing a stable connection under heavy forces and reducing storage volume by up to 95%.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screw connections are used to connect frame parts, then assembly is easy, but the connections come loose under heavy forces
Solution Approach 1:
The connection system is divided into two independent parts: a clamping connection for initial assembly and a secondary connecting element for securing. This segmentation allows each component to perform its specific function - the clamping connection provides easy assembly while the secondary element ensures reliability under heavy forces.
Solution Approach 2:
The clamping connection performs the preliminary action of bringing the frame parts into close proximity and maintaining assembly alignment. This preliminary clamping enables the subsequent insertion and securing of the secondary connecting element, ensuring proper positioning before final fixation.
2Reliability
If welded connections are used to prevent loosening, then connection stability is improved, but assembly becomes complex and storage space increases
Solution Approach 1:
Rather than using a single welded connection, the system segments the connection into a clamping mechanism and a secondary securing element. This segmentation provides welded-level stability while maintaining disassemblability, reducing assembly complexity compared to traditional welding.
Solution Approach 2:
The connection system transitions from a static welded joint to a dynamic, multi-stage connection process. The clamping connection allows for adjustment and positioning, while the secondary element provides final securing, enabling both stability and operational flexibility.
3Adaptability or versatility
If conventional tables are stored without load, then they are ready for reuse, but they occupy significant storage space
Solution Approach 1:
The table is segmented into separable frame parts that can be disconnected and stored in a compact configuration. This segmentation reduces storage volume by up to 95% while maintaining the ability to quickly reassemble the table for reuse, enhancing adaptability between storage and operational states.

AI summary
A method for constructing a cultivation and/or transport table, wherein a first and a second profile are interconnected at an angle, preferably an approximately straight angle, for forming a cultivation and/or transport table frame, wherein the first profile and the second profile are interconnected with the aid of a connecting element, and a profile part of the first profile engages behind a profile part of the second profile.
