Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the volume of the gas storage reservoir is increased to store more gas, then the gas storage capacity is improved, but the tension on the membrane material increases and it becomes easier to rupture
Solution Approach 1:
The membrane structure is divided into multiple layers (inner membrane and outer membrane) with cable nets integrated between them. This segmentation distributes the mechanical stress across multiple components rather than concentrating it on a single membrane layer, allowing larger volume while maintaining structural integrity.
Solution Approach 2:
The gas storage reservoir employs a composite structure combining membrane materials with cable net elements. The cable nets provide tensile strength and structural support, while the membranes provide containment. This composite approach enables the reservoir to achieve larger volumes without compromising the strength and rupture resistance of the membrane material.
2Duration of action of stationary object
If the gas storage reservoir operates for a long time to meet peak period needs, then the energy storage duration is improved, but gas leakage increases
Solution Approach 1:
The sandwich cavity positioned between the inner and outer membranes acts as a protective buffer that maintains structural stability and prevents gas leakage during long-term operation. This pre-configured protective structure compensates for potential weaknesses in the membrane system before they can lead to leakage.
Solution Approach 2:
The multi-layer composite structure with inner membrane, outer membrane, and intermediate cable net creates multiple barriers against gas leakage. This composite design enhances the overall sealing performance and durability, allowing the reservoir to maintain integrity over extended storage durations.
