Modular Overvoltage Protection with Removable Ignition Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overvoltage protection designs require the entire product to be replaced when the ignition circuit is damaged, and they are difficult to inspect, as the ignition circuit cannot be separated from the protection element, leading to unnecessary replacement of undamaged components.
Innovation Solution
A modular design featuring a base with protection elements and a removable module with a three-pole metallic contact system, allowing the ignition circuit to be replaced independently, with optical and remote signaling of the ignition circuit's operating state for easy identification and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the ignition circuit and protection element are connected in one construction unit, then the device is compact and simple to manufacture, but the entire product must be replaced when the ignition circuit is damaged
Solution Approach 1:
The device is divided into two separate modules: a base unit containing the protection element and a removable module containing the ignition circuit. This segmentation allows the ignition circuit to be replaced independently without replacing the expensive protection element, resolving the contradiction between manufacturing simplicity and repair economy.
2Device complexity
If the ignition circuit and protection element are connected in one construction unit, then the device structure is simple, but the device is difficult to inspect
Solution Approach 1:
The ignition circuit is extracted into a separate removable module that can be easily detached from the base. This allows inspectors to remove and examine the ignition circuit independently without disassembling the entire device, resolving the contradiction between structural simplicity and inspection accessibility.
3Ease of repair
If the protection element is separated into the base and ignition circuit into a removable module, then the ignition circuit can be replaced independently, but the connecting system must transfer great stress from pulse currents
Solution Approach 1:
The removable module with the ignition circuit is designed to nest into the base unit, with the connecting system positioned to handle high current stresses. The robust connecting system is integrated into the base structure to provide mechanical strength while allowing the removable module to be easily replaced, resolving the contradiction between replaceability and connecting system durability.
