Soft Top Cloth With Integrated Clamping Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soft top cloths for vehicles cannot incorporate technical function edges and grooves, limiting their ability to prevent water ingress and offering limited aesthetic design options, as they require external materials like plastics or sheet constructions.
Innovation Solution
A stretchable cloth for soft tops with integrated flexible clamping devices that deform to follow the contours of solid elements, allowing for the creation of both functional edges and grooves while maintaining aesthetic freedom, using techniques like form-locking seams and elastic modules to counteract ballooning effects at high speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a continuous soft top cloth is used, then the aesthetic design freedom is improved, but the ability to create technical function edges and grooves deteriorates
Solution Approach 1:
The continuous cloth is segmented by integrating discrete clamping devices at specific locations. These clamping devices create localized functional edges and grooves by deforming the cloth to follow contours of solid elements, while the rest of the cloth remains continuous for aesthetic purposes.
Solution Approach 2:
The cloth transitions from uniform continuous structure to having localized functional regions. Clamping devices are placed only where functional edges are needed, creating local deformations that follow solid element contours, while maintaining continuous cloth coverage elsewhere for aesthetic design freedom.
2Reliability
If external plastics or sheet constructions are added to create functional edges, then the water ingress prevention is improved, but the device complexity increases
Solution Approach 1:
The functional edge creation function is merged with the existing continuous cloth structure. Instead of adding separate plastic or sheet constructions, the clamping devices directly deform the cloth material itself to create functional edges, integrating multiple functions into a single system.
Solution Approach 2:
The cloth material itself serves the dual purpose of providing aesthetic coverage and creating functional edges when deformed by clamping devices. The cloth doesn't require external auxiliary constructions to create functional edges, as it can be deformed directly to follow solid element contours.
3Adaptability or versatility
If the cloth is made stretchable over solid elements, then the adaptability to vehicle contours is improved, but the structural stability deteriorates
Solution Approach 1:
Clamping devices are integrated into the cloth structure in advance, positioned to deform the cloth and follow solid element contours. This preliminary integration ensures that when the cloth is stretched over solid elements, the clamping devices automatically create the necessary deformations to maintain both adaptability and structural stability.
Solution Approach 2:
The continuous cloth acts as a flexible thin film that can be stretched over solid elements. Integrated clamping devices create localized rigid structures within this flexible medium, allowing the cloth to adapt to contours while maintaining structural stability through the form-locking clamping devices.
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
Enables the creation of functional edges and grooves within the cloth itself, effectively preventing water ingress and enhancing aesthetic design possibilities without compromising structural integrity or style.
Implementation Method 1
the cloth overstretching the solid element is deformed by suitable clamping devices such that the cloth substantially follows the contour of the offsetting or the indentation
Implementation Method 2
the clamping device is joined with the cloth according to the invention in such a form-locking manner that the application of stress in the clamping device results in that the cloth is deformed
Implementation Method 3
the elastic behavior may be conveyed by joined spring elements or the like, and may also be an inherent technical property of the clamping device
Implementation Method 4
it is therefore important to also incorporate the ballooning effect in the calculation such that a stress state of the clamping device is achieved which counteracts the lifting forces generating the ballooning effect
