Electrolytic Condenser Stopper and Holder for Controlled Gas Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion-proof mechanisms for electrolytic condensers fail to prevent the apparatus from being separated from the condenser due to electrolyte gas release during explosions, leading to potential collateral damage.
Innovation Solution
An explosion-proof apparatus comprising a stopper with effusion holes and a holder that securely attaches the condenser to a printed circuit board, where the stopper surrounds the condenser's explosion-proof face and lateral side, and the holder provides additional support and attachment points to prevent separation and manage gas release effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a stopper is combined with the electrolytic condenser to cover the explosion-proof face, then the scattering area of electrolyte is reduced, but the apparatus may be separated from the condenser due to electrolyte gas pressure
Solution Approach 1:
The apparatus is divided into separate functional components: a stopper that covers the explosion-proof face to contain electrolyte, and a holder that provides secure attachment to the circuit board. This segmentation allows each component to specialize in its function while working together as a system.
Solution Approach 2:
The holder acts as an intermediary component between the stopper and the circuit board, providing a secure mechanical connection that prevents separation. It transfers and distributes the mechanical stress and gas pressure forces, protecting the attachment points from direct exposure to high pressure.
2Object-generated harmful factors
If the top side of the casing is designed as an explosion-proof face, then gas release is enabled, but the apparatus may be damaged by electrolyte gas pressure
Solution Approach 1:
The stopper is designed to cover and protect the explosion-proof face, effectively extracting the weak point from direct exposure to harmful gas pressure. The effusion holes in the stopper provide controlled gas release while the stopper body shields the surrounding casing structure from direct pressure damage.
Solution Approach 2:
The holder is pre-installed to provide mechanical support and stress distribution before the explosion event occurs. This beforehand cushioning prevents the casing from suffering direct damage by distributing the gas pressure forces across a larger area and providing structural reinforcement.
3Object-generated harmful factors
If effusion holes are formed in the stopper, then electrolyte gas can be released, but gas pressure may damage the stopper structure
Solution Approach 1:
The stopper is designed with localized effusion holes that provide gas release functionality only where needed, while the rest of the stopper body maintains its structural integrity. The effusion holes are strategically positioned and sized to balance gas release requirements with structural strength requirements.
