Passenger Floor Recess Layout for Vehicle Pressure Vessels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traveling comfort in motor vehicles configured for gaseous fuel storage is impaired due to the presence of pressure vessels, which occupy space and affect passenger compartment layout.
Innovation Solution
A recess is configured in the passenger compartment floor to accommodate pressure vessels, allowing for a stable and efficient arrangement of pressure vessels using connectors that create a unified vessel unit, enabling additional space for passenger comfort and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pressure vessels are arranged below the passenger compartment floor, then the fuel storage capacity is ensured, but the traveling comfort of passengers is impaired
Solution Approach 1:
The pressure vessel arrangement is segmented into multiple individual pressure vessels arranged in parallel, with connectors positioned between them. This segmentation allows the connectors to be accessible from the passenger compartment through recesses in the floor, enabling space optimization without compromising fuel storage capacity.
Solution Approach 2:
The connectors are arranged in a dimension between the pressure vessels (laterally), rather than only above or below them. This intermediate positioning allows the connectors to be accessible from the passenger compartment through floor recesses, creating additional space for passenger comfort while maintaining the pressure vessel arrangement for fuel storage.
2Stability of the object's composition
If connectors are used to rigidly connect pressure vessels, then the structural stability is improved, but the complexity of the pressure vessel arrangement increases
Solution Approach 1:
Connectors are introduced as intermediary components that rigidly connect the pressure vessels to one another. These connectors serve as mediators that provide structural stability while being accessible from the passenger compartment through recesses, allowing for maintenance and inspection without increasing overall system complexity.
