Vehicle Floor Mat Fastening System with Push Plate Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicle floor mats tend to slip during driving and existing hook fasteners are inadequate for secure attachment to the vehicle floor carpet, making them difficult to keep in place effectively.
Innovation Solution
A fastening system comprising a ring unit with an inclined inner surface and a button unit with a notched cylinder and seesaw-type push rod, allowing for secure attachment and easy release of the mat to the vehicle floor carpet using a push plate mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mats are placed on vehicle floor carpet, then the carpet is protected from dirt, but the mat slips during driving
Solution Approach 1:
The mat is divided into modular sections with fastener units at strategic locations, allowing independent attachment points that collectively prevent slippage while maintaining ease of installation and removal
Solution Approach 2:
Fastener units are pre-installed on both the mat and the vehicle floor carpet during manufacturing, so that when the mat is placed, the fasteners are already positioned to immediately engage and prevent slippage without requiring additional adjustment by the user
2Reliability
If hook fasteners are used to attach the mat, then attachment security is improved, but the fastening mechanism is inadequate and difficult to operate
Solution Approach 1:
The fastener units incorporate movable components including a push rod that can shift position, allowing the fastening mechanism to transition between locked and unlocked states dynamically in response to user input, making operation intuitive and easy
Solution Approach 2:
A push plate serves as an intermediary element between the user's finger and the internal push rod mechanism, translating simple downward pressure into the complex sequence of movements required to release the locking mechanism and detach the mat

AI summary
A fastener includes first and second fastener units that releasably attach to one another. The first fastener unit includes a ring defining an inclined inner surface that narrows downward. The second fastener unit includes an upper plate defining a notched cylinder configured to abut the inclined inner surface of the ring; a lower plate having a seesaw-type push rod; and a push plate, which is operable by a user to press the push rod such that the push rod presses the ring upward. The push plate has a protrusion configured to press the notched cylinder against the inner surface of the ring when the fastener units are attached to one another, and to release the notched cylinder when the push plate is operated by the user. The first fastener unit may be in a vehicle floor mat, and the second fastener unit may be attached to a vehicle floor carpet.
