Solution Overview

Problem

Conventional floor mat fastening structures for vehicles require specific mats with molded rims, leading to issues like the rear circumferential edge rising and interfering with seat rails, causing sliding defects and grease adhesion problems, especially when the clearance between the vehicle floor and mat is small.

Innovation Solution

A floor mat fastening structure featuring fastening members with cutout openings and a sheet-like design, pivotally coupled to the mat's circumferential edge, allowing them to be sandwiched between the vehicle floor and interior members, preventing the mat edge from rising and ensuring secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional floor mat fastening structure with a molded rim portion is used, then the floor mat can be fastened to the vehicle floor, but the rear circumferential edge portion of the floor mat rises up and interferes with the seat rail during seat sliding

Engineering Contradiction:
Improvefastening stabilityVSAvoidinterference with seat rail
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The fastening structure is divided into separate components: a fastening member attached to the floor mat and a corresponding receiving structure on the vehicle floor. This segmentation allows the fastening member to be positioned away from the rear circumferential edge, preventing interference with seat rails while maintaining effective fastening.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening member is designed to extend in the width direction of the vehicle, perpendicular to the front-rear direction where seat sliding occurs. By positioning fastening points laterally rather than at the rear edge, the structure prevents interference with seat rail movement while maintaining fastening effectiveness.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If the clearance between vehicle floor and floor mat is small, then the floor mat fits closely, but the rear circumferential edge portion rises up and causes sliding defects

Engineering Contradiction:
Improvemat position stabilityVSAvoidseat sliding functionality
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The fastening function is separated from the mat edge structure. The fastening member is attached to the mat body at specific locations, allowing the rear circumferential edge to remain free and non-interfering with seat rails, thus maintaining both position stability and sliding functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening member acts as an intermediary between the floor mat and the vehicle floor structure. It provides the necessary anchoring force to prevent mat displacement while its positioning away from the rear edge eliminates interference with seat rail operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a molded rim portion is formed around the floor mat, then the floor mat can be fastened, but general floor mats without such rims cannot be used

Engineering Contradiction:
Improvefastening capabilityVSAvoidmat compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The fastening member is designed as a separate, attachable component that can be applied to various types of floor mats regardless of whether they have molded rims. This universal design allows the fastening system to work with different mat constructions, enhancing adaptability while maintaining reliable fastening capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fastening member is attached to the floor mat in advance during mat assembly. This preliminary attachment ensures that the fastening capability is built into the mat structure itself, allowing any mat type to be equipped with the necessary fastening features without requiring molded rims.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If the fastening structure uses a vehicle-side cover member with receiving portion, then the floor mat can be fastened, but the structure becomes complex and cannot be easily disposed

Engineering Contradiction:
Improvefastening stabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fastening function is extracted from the vehicle-side cover member structure and implemented through a separate fastening member attached to the floor mat. This extraction simplifies the overall structure by eliminating the need for complex integrated cover members with receiving portions, while maintaining effective fastening capability.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Provided is a floor mat fastening structure capable of preventing a circumferential edge portion of a mat main body from rising. This structure is to fasten a mat main body laid on a vehicle floor. A fastening member(s) are provided on a rear circumferential edge of the mat main body. The front end region of this fastening member is provided with an insertion portion having a cutout opening section. The fastening member is sandwiched between the vehicle floor and a foot bracket fixed on the vehicle floor such that the rising of the mat main body due to a long period of use can be restricted, thereby ensuring the quality of the product. Each fastening member is formed into the shape of a sheet, and has a flat upper and lower surfaces. Thus, the fastening member can be easily inserted in between the vehicle floor and the foot bracket.
