Multi-Chamber Container With Self-Releasing Membrane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-chamber containers for motor vehicles lack effective safety measures to prevent fluid leakage and structural failure under impact forces, as they often have chambers directly connected in fluid terms, leading to potential cracking and leakage during accidents.
Innovation Solution
A multi-chamber container design featuring at least two separate chambers connected via a material bridge or positive-locking mechanism that self-releases under deformation forces, ensuring each chamber remains intact and fluid-tight during impact, with optional integration of different materials for enhanced safety and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If chambers are connected by rigid intermediate walls or contracted regions to form a coherent housing, then structural stability is improved, but the container becomes prone to cracking and structural failure under impact forces
Solution Approach 1:
The patent employs a flexible membrane as a separating element between chambers, replacing rigid intermediate walls. This membrane can deform and absorb impact forces without cracking, while still maintaining the separation of different operating fluids. The flexible nature of the membrane allows it to accommodate deformation forces during accidents, preventing structural failure while preserving chamber integrity.
2Device complexity
If chambers are directly connected in fluid terms to form a multi-chamber container, then device complexity is reduced, but fluid leakage occurs during impact due to structural failure
Solution Approach 1:
The flexible membrane acts as both a structural separator and a fluid seal. It maintains the coherence of the container body while preventing fluid leakage between chambers during impact. The membrane's ability to deform elastically ensures that fluid pathways remain sealed even when the container undergoes deformation forces during accidents.
3Ease of manufacture
If the container body is constructed as a coherent assembly with rigid connections, then manufacturing simplicity is improved, but the container cannot self-release under deformation forces to prevent catastrophic failure
Solution Approach 1:
The patent introduces a dynamic separating element (flexible membrane) that can change its state under different loading conditions. During normal operation, the membrane maintains the coherent container structure. Under deformation forces during impact, the membrane can rupture or detach in a controlled manner, allowing the container to self-release and preventing catastrophic failure of the entire structure.
Solution Approach 2:
The patent converts the potentially harmful effect of rigid connections (which transmit impact forces throughout the structure) into a beneficial feature by using a flexible membrane that can selectively fail. The controlled rupture of the membrane under impact absorbs deformation forces and prevents the transmission of harmful stresses to other parts of the container, turning the weakness of the membrane into a safety feature.
