Magnetic Vehicle Floor Mat Fixture for Secure Low-Force Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle floor mat fixtures require significant force to hook and unhook the mat, leading to potential separation during driving, which can cause accidents and contamination, and expose clips, affecting aesthetics and safety.
Innovation Solution
A vehicle floor mat fixture using a magnetic force between a permanent magnet on a hooking protrusion and a column in the floor mat, combined with an elastic step and stopper mechanism, to securely attach the mat to a carpet clip, hiding the clip and reducing assembly force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional hooking mechanism is used to attach the floor mat to the carpet clip, then the attachment is secure, but significant force is required to hook and unhook the mat, leading to potential separation during driving
Solution Approach 1:
The patent replaces the conventional mechanical hooking system with a magnetic attachment system. Permanent magnets are embedded in both the carpet clip and the floor mat, creating a magnetic field that holds the mat securely without requiring mechanical interlocking. This substitution eliminates the need for significant assembly force while maintaining reliable attachment, as the magnetic force continuously holds the mat in place without the risk of accidental separation.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical (friction-based hooking) to magnetic (field-based attraction). By changing the fundamental parameter of attachment force from contact-based to field-based, the system achieves secure holding with minimal assembly force. The magnetic field strength can be adjusted by selecting appropriate magnet sizes and materials, allowing optimization between attachment security and ease of operation.
2Reliability
If the carpet clip is exposed for functional purposes, then the floor mat can be securely attached, but the exposed clip affects aesthetics and appearance
Solution Approach 1:
The patent applies the nesting principle by placing the functional carpet clip inside the decorative floor mat border. The clip is positioned in a recessed area or behind the mat's edge, making it invisible from the exterior view. This allows the clip to perform its attachment function while being concealed within the mat structure, thus maintaining both functionality and aesthetics simultaneously.
Solution Approach 2:
The floor mat border acts as an intermediary element that mediates between the functional clip and the aesthetic requirement. The border conceals the clip while the magnetic attachment system provides the necessary holding force. This intermediary structure allows the clip to remain hidden while still performing its attachment function effectively.
3Strength
If significant force is required to attach the floor mat, then the attachment is firm, but the mat may separate during driving due to vibration and movement
Solution Approach 1:
The patent replaces the mechanical friction-based attachment with a magnetic field-based attachment. The magnetic force provides continuous, uniform pressure across the entire contact surface between the mat and clip, creating a more reliable attachment that resists separation during driving. Unlike mechanical hooking that relies on initial assembly force, the magnetic field continuously exerts holding force, preventing separation even under vibration and movement conditions.

AI summary
The present invention is provided so that a hooking operation is performed using a magnetic force of a permanent magnet when a floor mat is hooked on a hooking protrusion formed to protrude, and thus the floor mat can be mounted on a floor carpet to easily safely use the floor mat using a small force. In addition, as the present invention includes an upper member and a lower member so that the upper member finish is performed to prevent a carpet clip from being visible, the carpet clip is not exposed to a vehicle interior when the floor mat is installed to improve aesthetics and appearance of the vehicle interior. In addition, as the present invention is provided so that floor carpet is disposed between a pressing member and a base of the carpet clip to forcibly fix the carpet, the floor mat is stably fixedly supported and conveniently used in a state in which the carpet clip is firmly fixed to the floor carpet.
