3D Cover Strip for ISOFIX Access and Seat Upholstery Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child seat fastening devices for vehicle seats often require complex cover designs and separate plastic covers for ISOFIX fastening devices, which can be cumbersome and aesthetically unappealing, while also complicating the integration of fastening units into the vehicle seat's upholstery.
Innovation Solution
A modular, three-dimensionally shaped cover system with reference panels or strips that can be integrated into the vehicle seat, featuring through-openings for access to fastening units and designed to be detachable or fixed, using deformable and stabilizable materials to simplify the integration and reduce seam lines, allowing for decorative and functional surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex cover design with separate plastic covers is used for ISOFIX fastening devices, then the fastening devices can be covered and accessed, but the device complexity increases and aesthetic appearance deteriorates
Solution Approach 1:
The patent combines the cover function and fastening device function into a single integrated unit. The cover is formed as one piece with the fastening device, eliminating the need for separate plastic covers and multiple components. This merging reduces device complexity while maintaining the ability to cover and access the fastening device.
Solution Approach 2:
The cover is designed to serve multiple functions simultaneously: it provides aesthetic covering, enables access to the fastening device through integrated openings, and maintains structural rigidity. This multi-functionality eliminates the need for separate specialized components for each function.
2Ease of operation
If separate plastic covers are used for ISOFIX fastening devices, then the fastening devices can be covered, but the integration into vehicle seat upholstery deteriorates
Solution Approach 1:
The cover is integrated directly with the fastening device as a single unit, allowing the entire assembly to be installed as one component into the vehicle seat upholstery. This eliminates the need for separate plastic covers and improves integration with the seat structure.
3Adaptability or versatility
If multiple separate covers are used for front and rear fastening units, then each fastening unit can be covered independently, but the manufacturing complexity increases
Solution Approach 1:
The cover is designed as a single piece that is segmented or divided to provide independent access to front and rear fastening units. This segmentation is achieved through integrated openings or foldable sections in the cover itself, rather than using multiple separate cover components, thereby simplifying manufacturing.
4Ease of operation
If conventional cover designs are used, then fastening devices can be covered, but aesthetic appearance deteriorates
Solution Approach 1:
The cover and fastening device are merged into a single integrated unit with a unified design. This eliminates the aesthetic discontinuity caused by separate plastic covers and creates a cohesive, visually appealing appearance that matches the vehicle seat's overall design.
