Solution Overview
Problem
Conventional laundry drying racks face challenges in complex and costly manufacturing processes, unsightly connecting points, and lack of torsional rigidity due to bending and welding of metal tubes, as well as increased risk of twisting with traditional connections.
Innovation Solution
A laundry drying rack design utilizing plug-in connection elements with deformation elements that deform the support tubes during assembly, eliminating the need for additional attachment methods and providing secure, anti-twisting connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bending and welding connections are used to assemble support tubes, then structural strength and torsional rigidity are improved, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The support structure is divided into modular segments (support tubes) that can be independently manufactured and then assembled through plug-in connections, eliminating the need for complex bending and welding operations while maintaining structural integrity
Solution Approach 2:
A plug-in connection element serves as an intermediary component between support tubes, providing a simplified assembly mechanism that replaces complex welding operations while ensuring structural strength through controlled deformation
2Stability of the object's composition
If bending and welding connections are used to assemble support tubes, then structural integrity is improved, but the appearance deteriorates due to unsightly connecting points and coating flaking
Solution Approach 1:
By segmenting the structure into plug-in modules rather than continuous bent tubes, the connecting points become standardized, hidden components rather than visible defects, preserving the aesthetic appearance of the overall structure
Solution Approach 2:
The plug-in connection elements are designed as simple, replaceable components that can be manufactured cost-effectively and provide sufficient service life, replacing expensive and aesthetically problematic welding operations
3Ease of operation
If traditional plug-in connections are used without deformation elements, then assembly simplicity is improved, but torsional rigidity deteriorates due to increased risk of twisting
Solution Approach 1:
The deformation elements are pre-positioned within the plug-in connection elements to automatically engage and deform the support tube during the insertion process, providing anti-twisting protection without requiring additional assembly steps
Solution Approach 2:
The support tube itself serves as the fastening mechanism through controlled deformation by the deformation elements, eliminating the need for separate fasteners like screws or rivets while ensuring torsional rigidity through the deformed connection

AI summary
The invention relates to a laundry drying rack comprising individual supporting tubes (4). The known supporting tubes (4) are rigidly connected to each other. This is complex and requires high wall thicknesses of the supporting tubes (4) so as to prevent torsion of the supporting tubes (4), and thus instability. The invention provides an improvement in that an anti-torsion mechanism is provided, wherein the supporting tubes (4) are connected to each other by way of plug connection elements (1), in which deformation elements (6, 7) are provided for deforming the ends of the supporting tubes (4) upon insertion into the plug connection elements (1).
