3D Lining Strip Covering for Simplified ISOFIX Seat Trim
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coverings for fastening devices of child seats on vehicle seats are complex and require multiple components, making them difficult to integrate and access, particularly for ISOFIX fastening systems.
Innovation Solution
A modular, three-dimensionally shaped covering unit designed as a lining strip that can be integrated into the vehicle seat, featuring passage openings for access to fastening devices, made from deformable and stabilizable materials like nonwovens, which can be sewn into the seat lining and provide decorative surfaces, reducing the need for separate coverings and simplifying the trim around fastening devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional covering for fastening devices is used, then the fastening device is covered and integrated into the seat, but the covering requires multiple separate components and complex trim around the fastening devices
Solution Approach 1:
The patent combines multiple separate covering components into a single integrated covering element that encompasses the entire fastening device. This merging approach eliminates the need for multiple separate trim pieces and simplifies the overall structure while maintaining coverage and aesthetic integration with the seat.
Solution Approach 2:
The covering element serves multiple functions simultaneously: it covers the fastening device for aesthetic purposes, provides structural integration with the seat, creates passage openings for access, and simplifies manufacturing. This multi-functionality reduces the need for separate components and trim pieces.
2Ease of operation
If the covering is designed to provide access to fastening devices, then access is enabled, but the covering structure becomes more complex with multiple components
Solution Approach 1:
The patent extracts the access function from separate cover components and integrates it directly into the single covering element through passage openings. This allows access to the fastening device while maintaining the simplicity and integrity of the unified covering structure.
3Adaptability or versatility
If separate coverings are used for front and rear fastening units, then each fastening unit is individually covered, but the overall trim complexity increases
Solution Approach 1:
The patent merges separate coverings for front and rear fastening units into a single continuous covering element that accommodates both fastening devices. This unified approach reduces trim complexity while providing comprehensive coverage for all fastening units.
