Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular pressure vessel mounting systems face challenges in efficiently supporting carbon-recapture vessels on vehicle platforms, particularly in maintaining structural integrity and accommodating volumetric changes, while adhering to weight constraints and minimizing stress concentrations.
Innovation Solution
A vehicular pressure vessel mounting system that includes a set of mounts and a retention mechanism, allowing for the vertical mounting of composite overwrapped pressure vessels between a vehicle's cab and trailer, with mounts designed to distribute axial loads along the vessel's outer wall and accommodate dimensional changes, and retention mechanisms that are pre-loaded and elastically deformable to maintain frictional contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pressure vessels are mounted vertically on vehicle platforms, then packing density and mass efficiency are improved, but stress concentrations and structural integrity are worsened
Solution Approach 1:
A mount structure acts as an intermediary between the pressure vessel and vehicle frame, featuring a curved contact surface that distributes axial loads around the vessel's circumference rather than concentrating them at discrete points, thereby maintaining structural integrity while enabling vertical mounting for improved packing density
Solution Approach 2:
The mount structure incorporates a curved contact surface with specific geometric properties tailored to match the vessel geometry, creating localized optimal contact zones that distribute stresses evenly while maintaining the overall vertical mounting configuration for space efficiency
2Stability of the object's composition
If rigid mounting structures are used to support pressure vessels, then structural stability is improved, but adaptability to volumetric changes is worsened
Solution Approach 1:
The mount structure incorporates elastomeric material that provides flexible, compliant contact surfaces capable of deforming to accommodate volumetric changes in the pressure vessel while maintaining stable structural support and frictional retention forces
Solution Approach 2:
The mounting system transitions from a static rigid connection to a dynamic system where the elastomeric material can deform and adapt its shape in response to vessel volume changes, while the pre-loaded retention mechanism maintains continuous frictional contact
3Reliability
If retention mechanisms apply high clamping forces to secure pressure vessels, then retention reliability is improved, but stress concentrations on the vessel are worsened
Solution Approach 1:
The mount structure with curved contact surface serves as an intermediary that distributes the clamping forces from the retention mechanism around the vessel circumference, preventing stress concentrations while maintaining reliable retention through the combined effect of friction and normal forces
