Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for securing thin, flat materials like awnings fail to effectively prevent sagging and fluttering due to wind and vibrations, while maintaining structural integrity and ease of assembly.
Innovation Solution
A fixing device using elongated, oblong magnetic or magnetizable connecting elements that attach to both sides of the flat material and a supporting structure, providing even tension and damping vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If point magnets are used to attach the covering to the supporting structure, then the assembly is simple, but the covering sags and flutters under wind and vibration loads
Solution Approach 1:
The magnetic attachment system is divided into multiple discrete magnetic elements distributed across the covering rather than using a single attachment point. This segmentation allows the covering to be held stable at multiple locations simultaneously, preventing sagging and fluttering while maintaining ease of assembly through modular attachment
Solution Approach 2:
The attachment system transitions from point-contact magnets to elongated magnetic elements that provide surface-area contact. This dimensional change from zero-dimensional points to one-dimensional elongated elements distributes the holding force across a larger area, effectively preventing the covering from sagging between attachment points
2Stability of the object's composition
If the covering is tightly secured to prevent sagging, then material stability is improved, but the structure becomes more complex
Solution Approach 1:
The patent replaces complex mechanical fastening systems (clamps, clips, straps, or multiple attachment points) with a magnetic attachment system. The magnetic force provides the necessary tension and stability without requiring mechanical fasteners, thereby maintaining material stability while reducing structural complexity
Solution Approach 2:
The magnetic attachment system changes the physical parameter of force application from mechanical contact forces to magnetic forces. This allows for adjustable and distributed tension across the covering through the magnetic field, achieving material stability without complex mechanical structures
3Stability of the object's composition
If magnets are attached to both sides of the covering, then vibration damping is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent combines the vibration damping function with the existing magnetic attachment system by integrating magnetic elements on both sides of the covering. This merging of functions allows the same magnetic elements that provide attachment to also serve as vibration dampers, reducing manufacturing complexity compared to adding separate damping components
