Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastener clips for attaching automobile body panels to vehicle chassis are difficult to install, lack flexibility, and fail to adequately secure panels with varying sheet metal curvatures and thicknesses, leading to sagging, noise, and aesthetic issues over time.
Innovation Solution
A magnetic bracket with upward posts and notches allows for blind insertion and secure attachment to non-magnetic chassis surfaces, using magnets for self-alignment and adaptation to different curvatures and thicknesses, providing high extraction force and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fastener clips are used to attach body panels to vehicle chassis, then the panels can be secured to the chassis, but the installation process becomes difficult and time-consuming due to alignment requirements and blind insertion constraints
Solution Approach 1:
The patent replaces the conventional mechanical fastening system (screws, clips requiring alignment) with a magnetic fastening system. The magnetic bracket uses magnetic attraction forces to automatically align and secure body panels to the chassis, eliminating the need for precise alignment and blind insertion operations. The magnetic force provides self-aligning capability that simplifies the installation process and reduces assembly time.
Solution Approach 2:
The magnetic bracket system provides self-alignment through magnetic attraction. When the body panel approaches the chassis, the magnetic force automatically guides and positions the panel correctly without requiring manual alignment or visual inspection by the installer. This self-service capability eliminates alignment requirements and makes blind insertion easy and quick.
2Adaptability or versatility
If conventional fasteners are used to secure body panels, then attachment is achieved, but the fasteners fail to adapt to varying sheet metal curvatures and thicknesses, causing sagging and aesthetic issues
Solution Approach 1:
The magnetic bracket system is designed with dynamic characteristics that allow it to adapt to varying sheet metal curvatures and thicknesses. The magnetic force can accommodate dimensional variations and curvature changes in the chassis and body panels while maintaining secure attachment. This dynamic adaptability ensures reliable long-term security even when production tolerances or environmental changes cause variations in the mating surfaces.
3Measurement precision
If magnetic fasteners are used for blind insertion, then alignment is improved through magnetic attraction, but the device complexity increases due to integration of magnetic components
Solution Approach 1:
The patent merges the magnetic fastening function directly into the bracket structure itself. The magnetic bracket integrates the magnetic components (magnets, magnetic materials) as an inherent part of the bracket design, eliminating the need for separate alignment mechanisms or complex assembly procedures. This merging approach provides precise alignment through magnetic attraction while keeping the overall device structure relatively simple and manufacturable.

AI summary
A magnetic bracket includes a base and at least two posts at opposite ends of the base. The posts bend upwards from the base such that at least two clips are operable to attach at the posts at opposite ends of the base. The posts have a notch between the base and ends of the posts to permit the clips to hook onto the posts. The magnetic bracket may be clipped into a vehicle chassis by removably inserting the clips into a slot of the vehicle chassis. A body panel such as a headliner having a magnetic fastener attached to the body panel may then be magnetically self-aligned and removably attached to the base having a magnetic portion. The magnetic fastener is operable to be removably attached to the magnetic portion. The magnetic bracket is attached to a non-magnetic part of a vehicle chassis.
