Spring-Enhanced Ignition Electrodes for Durable Gas Stoves
Here’s PatSnap Eureka !
Summary
Problems
Conventional gas stoves face issues with ignition electrode durability due to external impact during cleaning, leading to potential detachment of the insulating ceramic layer and misfiring, as the electrodes are exposed and prone to damage from their heavy, hard brass construction.
Innovation solutions
A gas stove with an improved ignition electrode connection structure featuring a cover plate, connection base, and a spring device between the receiving part and electrode connection part, which reduces the risk of damage to the insulating ceramic jacket through the use of a compression spring, and additional design elements like positioning grooves and a spring washer for secure alignment and support.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If the burner is removed for cleaning, then the area around the burner can be cleaned, but the ignition electrodes protrude unprotected and can be damaged by external impact
Why choose this principle:
A spring device is installed between the connection base and the ignition electrode to provide beforehand cushioning. When external impact occurs on the protruding ignition electrode during burner removal or cleaning, the spring device absorbs the impact force through elastic deformation, preventing damage to the ceramic insulating layer and electrode structure.
Principle concept:
If the burner is removed for cleaning, then the area around the burner can be cleaned, but the ignition electrodes protrude unprotected and can be damaged by external impact
Why choose this principle:
The spring device acts as an intermediary element between the rigid connection base and the fragile ignition electrode. This intermediary component provides mechanical cushioning and protects the electrode from direct transmission of impact forces, while still maintaining electrical connection functionality.

Abstract
The stove has a cover plate (5) with an ignition electrode opening (9), and a connecting base (6) arranged below the cover plate. The base has receiving parts (10, 23) for receiving an ignition electrode (4). The ignition electrode has an insulated ceramic casing (3) and electrode connecting parts (8, 27), where the ignition electrode is connected with the connecting base through a connection of the receiving parts and the electrode connecting parts. A spring device i.e. pressure spring (24), is arranged between the receiving parts and the electrode connecting parts.
