Solution Overview
Problem
Existing vehicle seat structures with automatic belt units face challenges in optimizing structural space and force flow, while also requiring cost-effective assembly methods.
Innovation Solution
A vehicle seat structure with a structural component housing an automatic belt unit, connected in a positive-locking, materially engaging, or non-positive-locking manner to another load-bearing component, optimizing space and force distribution, and featuring a method for assembling these components to ensure efficient and cost-effective integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the automatic belt unit is arranged in a hollow space of the structural component, then the structural space is optimized, but the assembly complexity increases
Solution Approach 1:
The automatic belt unit is nested within the hollow space of the structural component, allowing one component to be placed inside another. This nesting approach optimizes structural space by utilizing the existing hollow volume, while the integrated design reduces assembly complexity by pre-positioning the belt unit within the structural component during manufacturing.
2Strength
If the structural component is connected in a positive-locking manner to another component, then the strength and rigidity are improved, but the manufacturing cost increases
Solution Approach 1:
The connection system is segmented into modular positive-locking elements that can be independently manufactured and assembled. This segmentation allows for standardized production of connection components, reducing overall manufacturing cost while maintaining the strength and rigidity benefits of positive-locking connections.
3Force
If the structural component forms part of the seat substructure, then the force flow is optimized, but the device complexity increases
Solution Approach 1:
The structural component serves multiple functions: it provides structural support, houses the automatic belt unit, and forms an integral part of the seat substructure for optimized force flow. This multi-functionality approach consolidates several components into one, reducing overall device complexity while achieving optimized force distribution during vehicle occupancy and crash events.
