Deformable Case Shell Connector for Explosion Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The explosion of devices inside electric power apparatuses, such as inverters, leads to the components of the case shell being blown away, posing a safety risk to surrounding equipment and personnel.
Innovation Solution
A deformable connector is integrated into the case shell, allowing components to slightly separate during an explosion, forming a gap to release pressure and maintain connection, preventing components from being blown out and ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the case shell components are rigidly connected to maintain structural strength, then the structural strength is improved, but the explosion pressure cannot be released and components may be blown away
Solution Approach 1:
The connector main body is designed to be deformable rather than rigid, allowing it to dynamically adjust its state based on external forces. During normal operation, it maintains a rigid connection to provide structural strength. During explosion, it deforms to allow pressure release, thus resolving the contradiction between maintaining strength and releasing harmful pressure.
Solution Approach 2:
The connector changes its physical state from rigid to deformable under extreme pressure conditions. The main body material or structure is designed to undergo parameter changes (deformation) when subjected to explosion forces, transitioning from a state that maintains structural integrity to a state that allows pressure relief, thereby resolving the contradiction between strength and pressure release.
2Reliability
If the connector is made deformable to release explosion pressure, then the safety is improved, but the connection stability deteriorates
Solution Approach 1:
The connector employs dynamic characteristics by being designed to deform under extreme conditions rather than remain statically rigid. This deformability allows it to adapt to explosion forces while maintaining connection, improving safety without completely sacrificing connection stability as the connector remains attached despite deformation.
Solution Approach 2:
The deformable main body acts as a pre-designed cushioning element that absorbs and mitigates explosion forces. By anticipating potential explosion scenarios, the connector is designed to deform in a controlled manner to cushion the impact, thereby improving safety while maintaining a form of connection stability through the deformable link.
3Ease of manufacture
If the main body is designed as a simple rigid structure for ease of manufacture, then the ease of manufacture is improved, but the ability to deform during explosion is reduced
Solution Approach 1:
The main body is designed with material or structural parameters that enable deformation under extreme conditions. This could involve selecting materials with specific stress-strain characteristics or designing a structure that undergoes controlled deformation, balancing manufacturability with the required adaptability to explode-safe conditions.
Solution Approach 2:
The main body incorporates flexible or deformable structural elements that can bend or deform during explosion events. This design approach maintains relative ease of manufacture while providing the necessary deformability to allow pressure release and improve safety during abnormal conditions.
