Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recombination systems for lead-acid batteries face issues with water drainage, where condensate droplets can wet and clog gas-permeable ceramics, reducing efficiency, and previous solutions involve additional components or design modifications, increasing costs and assembly complexity.
Innovation Solution
A process medium guide device with a conical or meandering structure is integrated or attached above the recombination unit to direct condensate away from the ceramic, preventing wetting and maintaining efficiency, with options for seamless integration or plug connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a recombination device with gas-permeable ceramic is used to catalytically recombine hydrogen and oxygen, then recombination efficiency is improved, but water condensation can wet and clog the ceramic pores, reducing gas transport efficiency
Solution Approach 1:
The patent extracts the harmful condensate from the recombination device by introducing a separate drainage system. The drainage channel is integrated into the recombination device housing, providing a dedicated pathway for condensate to be removed from the system, preventing it from wetting the ceramic and maintaining gas transport efficiency.
Solution Approach 2:
The patent introduces an intermediary drainage channel as a mediator between the recombination chamber and the external environment. This channel serves as an intermediate structure that captures and transports condensate away from the ceramic, acting as a buffer that prevents direct contact between harmful condensate and the sensitive recombination surfaces.
2Object-affected harmful factors
If additional shielding elements or drip caps are added to prevent water formation, then ceramic wetting is prevented, but device complexity and assembly effort increase
Solution Approach 1:
The patent merges the drainage function directly into the recombination device housing structure. The drainage channel is integrated into the existing housing design, eliminating the need for separate shielding elements or drip caps. This consolidation maintains ceramic protection while reducing the total number of components and simplifying assembly procedures.
Solution Approach 2:
The recombination device housing is designed to serve multiple functions: it contains the recombination chamber, provides structural support, and incorporates the drainage channel for condensate removal. This multi-functionality eliminates the need for additional specialized components, reducing device complexity while maintaining effective ceramic protection.
3Ease of operation
If a drainage system is integrated into the recombination device, then assembly effort is reduced, but device structure becomes more complex
Solution Approach 1:
The drainage channel is designed as a separate, modular component that can be independently manufactured and then assembled into the recombination device housing. This segmentation allows for simplified manufacturing of individual parts and straightforward assembly, reducing overall assembly effort while avoiding the complexity of fully integrated monolithic structures.
