Fuel Cell Humidifier Shell Reinforcing Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shell reinforcing structures for fuel cell humidifiers require large space and are unable to bear significant pressure, posing safety hazards due to the use of reinforcing ribs that occupy space and are not effective under external forces.
Innovation Solution
A shell reinforcing structure comprising a main body shell, fixed plates, grating mechanisms, and membrane tubes that enhance pressure resistance without the need for external reinforcing ribs, allowing the shell to be fixed and maintained conveniently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcing ribs are arranged on the surface of the shell, then the pressure resistance of the shell is improved, but the space occupied by the humidifier is greatly reduced
Solution Approach 1:
The patent applies nesting by placing the grating mechanism inside the hollow layer of the shell structure. The grating mechanism comprises gratings and membrane tubes that are nested within the existing shell volume, eliminating the need for external reinforcing ribs. This internal nesting provides pressure resistance while maintaining compact space occupation.
Solution Approach 2:
The patent uses membrane tubes as part of the grating mechanism to provide pressure resistance. These flexible membrane structures can withstand pressure while occupying minimal space, replacing the need for rigid external reinforcing ribs that would consume significant volume.
2Strength
If reinforcing ribs are arranged on the surface of the shell, then the pressure resistance of the shell is improved, but the device complexity is increased
Solution Approach 1:
The patent merges the reinforcing function with the existing shell structure by integrating the grating mechanism into the hollow layer. Instead of adding separate external reinforcing ribs, the pressure resistance function is combined with the internal shell structure, reducing overall device complexity.
Solution Approach 2:
The grating mechanism with membrane tubes provides self-reinforcing capabilities within the shell structure. The membrane tubes can expand and contract with pressure changes, providing automatic pressure resistance without requiring complex external support structures or additional reinforcement components.
3Strength
If reinforcing ribs are arranged on the surface of the shell, then the pressure resistance of the shell is improved, but the fuel cell humidifier and fuel cell are damaged to cause potential safety hazards
Solution Approach 1:
The membrane tubes in the grating mechanism provide flexible pressure resistance that can adapt to external forces without causing damage. These flexible structures absorb and distribute pressure loads evenly, preventing the stress concentrations that could lead to shell or fuel cell damage.
Solution Approach 2:
The grating mechanism with membrane tubes acts as a cushioning structure that absorbs external pressure before it can reach the main shell and fuel cell components. This pre-cushioning effect protects the fuel cell from damage under external forces.
