Solution Overview
Problem
Existing vehicle seat belt frameworks face challenges in providing a cost-effective and economically advantageous design that meets stability-related criteria, particularly in maximizing loading resistance during dynamic events like road traffic accidents.
Innovation Solution
A belt framework comprising vertical supports and a horizontally running transverse strut, with a safety element encasing the transverse strut to enhance stability, and featuring a frame-like design with metallic profiles and adjustable fastening mechanisms for secure attachment to the vehicle structure, allowing for the absorption and transfer of forces and moments during crashes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a belt framework is designed to meet stability-related criteria and maximum-loading situations, then stability and safety are improved, but production costs and manufacturing complexity increase
Solution Approach 1:
The belt framework is divided into separate modular components including vertical supports, transverse struts, and attachment elements that can be manufactured independently and assembled together. This segmentation allows each component to be optimized for its specific function while simplifying manufacturing processes and reducing overall production costs.
Solution Approach 2:
The transverse strut is designed with multiple functions: it provides structural support, serves as an attachment element for passenger-restraint systems, and connects vertical supports. This multi-functionality reduces the number of separate components needed, simplifying the overall structure and manufacturing while maintaining stability.
2Stability of the object's composition
If the transverse strut is made longer than the distance between vertical supports to provide stability, then stability is improved, but weight and material usage increase
Solution Approach 1:
The transverse strut extends beyond the vertical supports in the horizontal dimension, creating a moment arm that provides rotational stability. This dimensional extension allows the framework to resist tipping forces without requiring additional vertical supports or increasing the weight of individual components.
Solution Approach 2:
The framework utilizes composite construction with metallic profiles that optimize the strength-to-weight ratio. By selecting appropriate materials and cross-sectional geometries, the transverse strut achieves the necessary stiffness and strength for stability while minimizing weight.
3Adaptability or versatility
If vertical supports are spaced further apart to accommodate multiple seating positions, then versatility is improved, but structural strength and stability decrease
Solution Approach 1:
The belt framework is designed with adjustable components including movable attachment elements and flexible restraint system connections that allow the same structural framework to accommodate different seating configurations and passenger positions without requiring structural modification.
Solution Approach 2:
The vertical supports are positioned to provide optimal structural strength at critical load-bearing locations, while the spaces between them are utilized for seating. The attachment elements are strategically placed at specific heights and positions on the supports to maintain structural integrity while enabling multiple seating arrangements.
