Gas Accumulator Membrane Access Opening Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas storage devices face challenges with load safety due to varying gas pressures, leading to potential membrane damage and high costs, and lack simple maintenance and monitoring access without additional structural support.
Innovation Solution
A gas storage device design where the outer through-opening is exclusively held by the membrane, allowing for access, maintenance, and monitoring without separate supporting structures, with options for multiple openings and flexible covers for pressure relief and measurement access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional structural measures (shafts, rigid suspensions) are added to provide access openings, then access and maintenance capability is improved, but device complexity increases
Solution Approach 1:
The invention extracts the access opening function directly from the membrane structure itself, rather than adding separate rigid shafts or suspension systems. The through-opening is formed directly in the membrane, allowing access while maintaining the membrane's flexibility and simplicity.
Solution Approach 2:
The invention uses the membrane's inherent flexibility to create the access opening structure. The membrane itself forms the through-opening with its boundary held exclusively by the membrane material, eliminating the need for rigid structural supports and maintaining the thin-film characteristic.
2Stability of the object's composition
If rigid shafts or fixed structures are used for access openings, then structural stability is improved, but ease of manufacture and assembly worsens due to additional mounting requirements
Solution Approach 1:
The invention merges the access opening function with the membrane structure itself. The through-opening and its boundary are integrated into the membrane, eliminating separate mounting structures and simplifying assembly while maintaining stability through the membrane's own structural integrity.
3Reliability
If through-openings are connected directly to rigid housings or pressure equalization ducts, then pressure control capability is improved, but service access capability deteriorates
Solution Approach 1:
The invention uses the flexible membrane as an intermediary between the gas storage space and the external environment. The membrane's through-opening provides pressure equalization functionality while its flexible nature and direct formation in the membrane material maintain service access capability, unlike rigid connections that block access.

AI summary
The invention relates to a gas accumulator comprising a gas accumulator room (20), at least one membrane (1, 2) surrounding the gas accumulator room (20) at least partially, and at least one discharge line (40) leading out of the gas accumulator room (20) for discharging the stored gas, wherein from the at least one membrane (1, 2) a closable outside through passage (3) is removed, via which the gas accumulator room (20) communicates with the surrounding area in the unclosed state of the outside through passage (3).
