Vehicle Seat Belt Mount with Multi-Point Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat belt mounts lack a stable and adaptable attachment mechanism that can effectively distribute mechanical loads during dynamic events, such as accidents, while also considering economic manufacturing and installation aspects.
Innovation Solution
A belt mount with a support arrangement featuring vertically oriented elongated profiles and a horizontally oriented cross-strut, which provides a mechanically rigid connection to the vehicle structure above the floor, allowing for anchoring at multiple resilient points, including vehicle walls and pillars, to enhance stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a belt mount is attached only to the vehicle floor, then the attachment mechanism is simple, but the stability and load distribution during dynamic events is insufficient
Solution Approach 1:
The attachment mechanism is segmented into multiple independent attachment points distributed across the vehicle structure (floor, walls, pillars). Each attachment point can independently bear load, and the loss of one point does not compromise the entire system. This segmentation enhances reliability while keeping individual attachment points simple.
Solution Approach 2:
The attachment mechanism transitions from a single-plane (floor-only) attachment to a multi-dimensional attachment system that utilizes vertical and lateral dimensions by connecting to walls and pillars. This spatial distribution of attachment points improves stability and load distribution without significantly increasing mechanical complexity.
2Strength
If a belt mount is designed for maximum loading situations, then safety criteria are met, but manufacturing and installation costs increase
Solution Approach 1:
The load bearing structure is divided into multiple vertical supports and horizontal cross-struts, each designed to handle portion of the total load. This segmentation allows for standardized, modular components that are easier and more cost-effective to manufacture while collectively achieving the required strength for maximum loading situations.
Solution Approach 2:
The belt mount utilizes composite construction combining vertical support elements and horizontal cross-struts made from materials optimized for their specific functions. This composite approach achieves high load bearing capacity while controlling manufacturing costs through material selection and structural efficiency.
3Reliability
If a belt mount uses multiple attachment points on the vehicle structure, then load distribution is improved, but the installation complexity increases
Solution Approach 1:
The attachment system is segmented into standardized attachment points with uniform interfaces and mounting procedures. This standardization enables installers to use the same techniques and tools for each attachment point, reducing overall installation complexity despite the increased number of attachment locations.
Solution Approach 2:
The attachment mechanism is designed with universal mounting features that can be adapted to different vehicle structures (floor, walls, pillars) using similar installation procedures. This universality simplifies installation across multiple attachment points by eliminating the need for point-specific complex procedures.
