Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure vessels, such as fiber-reinforced tanks, struggle to optimally utilize non-spherical installation spaces due to complex production methods and inefficiencies in using available space, particularly with honeycomb-type tanks, which require additional inner walls and resins, reducing the useful volume.
Innovation Solution
A pressure vessel design featuring a wall with embedded inner threads that brace against entry points, forming a matrix structure, allowing for stability without complex inner walls, and utilizing a matrix material without a liner for concave boundary surfaces, enabling efficient space utilization and production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If honeycomb-type tanks are used to adapt to non-spherical installation spaces, then space utilization is improved, but production complexity increases and useful volume is reduced due to additional inner walls and resin
Solution Approach 1:
The tank is divided into multiple spherical segments that can be assembled together to form complex shapes. This segmentation allows adaptation to various installation spaces while maintaining simple production of individual spherical units, avoiding the complexity of honeycomb structures.
Solution Approach 2:
Multiple spherical tanks are nested or arranged within a common support structure, allowing compact configuration in limited spaces. The inner threads and support structure provide structural integrity while minimizing space occupation, preserving useful volume.
2Stability of the object's composition
If honeycomb-type tanks are used with inner walls and resin, then structural stability is improved, but useful volume is reduced
Solution Approach 1:
The tank employs thin-walled spherical segments with integrated support structures instead of bulky inner walls. The wall threads and matrix provide necessary structural stability while minimizing material volume, maximizing the useful internal volume for fuel storage.
Solution Approach 2:
The tank utilizes composite construction with wall threads embedded in matrix material, providing high structural stability-to-weight ratio. This composite approach achieves required strength with minimal material volume, preserving useful space compared to traditional honeycomb structures with additional inner walls and resin.
3Adaptability or versatility
If serpentine tanks with multiple small diameter tanks are used, then adaptation to installation space is improved, but unused space between tanks increases
Solution Approach 1:
The tank system is segmented into multiple spherical units that can be configured in various arrangements. The support structure optimizes the spatial arrangement of these segments to minimize gaps and unused space, achieving both adaptability and space efficiency.
Solution Approach 2:
Instead of linear serpentine arrangements that create unused spaces between tanks, the spherical segments are arranged in three-dimensional configurations within the support structure, optimizing space utilization in all spatial dimensions and reducing unused volume.
