Magnetic Accessory Mount Base for Secure Removable Vehicle Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle accessory fixing systems, such as those on dashboards, often rely on inefficient adhesive or suction cup methods that are difficult to assemble and cannot be easily removed, leading to damage when the support is not in use.
Innovation Solution
A removable part and base system utilizing magnets with defined polarity and a translation guide element, allowing for semi-automatic locking and easy insertion/extraction, along with fuseable fixing elements and electrical contact terminals for secure and versatile accessory support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive or suction cup mounting systems are used, then the accessory support can be attached to the dashboard, but the system cannot be easily removed and may cause damage when not in use
Solution Approach 1:
The mounting system transitions from a static adhesive or suction cup attachment to a dynamic magnetic attachment system. The magnetic field allows the accessory support to be easily attached and detached by simply moving it close to or away from the base, providing both ease of operation and reliable attachment through magnetic force.
Solution Approach 2:
The patent replaces the mechanical adhesive or suction cup mounting system with a magnetic field-based system. The magnetic field provides the attachment force, eliminating the need for adhesives or suction cups and enabling easy removal without damage while maintaining secure attachment during use.
2Reliability
If magnets with defined polarity are positioned around the tip, then the magnetic attraction force facilitates insertion and improves attachment security, but the device complexity increases
Solution Approach 1:
The magnetic system serves multiple functions simultaneously: it provides attachment security through magnetic attraction, guides the accessory support into proper alignment during insertion, and enables easy removal when the magnetic field is weakened or reversed. This multi-functionality justifies the added complexity by eliminating the need for separate mechanical attachment and alignment mechanisms.
3Ease of operation
If the tip is held in a first angular position for insertion or extraction, then semi-automatic locking is achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The magnetic field automatically guides the accessory support into the correct angular position during insertion and holds it there through magnetic attraction. The system self-corrects any misalignment, eliminating the need for high-precision manual positioning or complex mechanical locking mechanisms, thereby reducing manufacturing precision requirements while achieving automatic locking.
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 system provides a secure, easy-to-assemble, and removable solution for accessory support in vehicles, reducing vibration and allowing for easy replacement of accessories while maintaining structural integrity during impacts.
Implementation Method 1
By incorporating magnets on the removable part and the base as described below, a magnetic attraction force can be created between the base and the removable part. This force is stronger when the magnets are aligned with the insertion direction or are nearly aligned.
Implementation Method 2
by holding the tip in a first angular position for insertion or extraction relative to the insertion direction, it is possible to create a tangential component of the magnetic force existing between the magnets of the removable part and the base when, in this first angular position, the magnets of the removable part and the base are not exactly aligned along the insertion direction

AI summary
The invention relates to an accessory mounting system (1) for a motor vehicle, comprising a base (10) for integration into the vehicle and a removable part (20) providing an accessory mount. Both the base (10) and the removable part (20) have magnets (103, 203) that secure the two parts together and provide semi-automatic locking of the removable part onto the base by rotating the removable part relative to the base until the attachment elements engage.
