Magnetic Soft Top Assembly Interference Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soft tops for off-road vehicles, such as JEEP models, lack the ability to remain securely attached when the removable roof is engaged and are limited to vehicles with specific roof anchors, necessitating an improved attachment mechanism.
Innovation Solution
A magnetic soft top apparatus featuring a main body with strategically positioned magnets, reinforcement straps, and latch assemblies that allow secure attachment to a vehicle's roll cage, including a forward magnetic assembly for interference fit within the vehicle's gap and additional magnets for engagement with the central and side bars, enabling secure positioning without the need for specific roof anchors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional soft tops use clip assemblies and latches to engage roof anchors and bars, then the soft top can be attached to vehicles with specific roof anchors, but the soft top cannot remain securely attached when the removable roof is engaged and is limited to vehicles with specific roof anchors
Solution Approach 1:
The patent replaces conventional mechanical attachment systems (clips, latches, and roof anchors) with a magnetic attachment system. Magnets are embedded in the soft top body to provide attachment force, eliminating the need for mechanical engagement with specific roof anchors. This substitution enables the soft top to remain securely attached while the removable roof is engaged and provides compatibility with a wider range of vehicle configurations.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical (clips and latches) to magnetic field-based interaction. By embedding magnets in the soft top body, the attachment parameter changes from mechanical interlocking to magnetic attraction, allowing the soft top to maintain secure attachment under different vehicle configurations and when the removable roof is engaged.
2Reliability
If the soft top uses a magnetic assembly with interference fit, then the soft top can remain in place when the removable roof is engaged, but the manufacturing complexity increases
Solution Approach 1:
The patent embeds magnets within the soft top body structure, creating a nested configuration where the magnets are integrated into the fabric layers. This nesting approach allows the magnetic attachment system to be incorporated into the existing soft top manufacturing process without requiring separate assembly steps, thereby reducing manufacturing complexity while maintaining reliable attachment when the removable roof is engaged.
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
The magnetic soft top provides a secure, interference fit and magnetic engagement system that allows the soft top to remain in place even when the removable roof is engaged, offering improved versatility and compatibility with a wider range of vehicles.
Implementation Method 1
a magnetic assembly 208 formed in the main body 202. Within the magnetic assembly shown 208, there are magnets 210-1 to 210-3 sewn in by way of pockets. The magnetic assembly 208 is positioned such that the magnets 210-1 to 210-3 engage the central bar 106 when the top 200 is secured to the vehicle 100.
Implementation Method 2
the first magnets is dimensioned such that first magnet, as secured to the main body, is configured to form an interference fit within a gap of a forward assembly of a vehicle
