Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas stoves face issues with ignition electrode durability due to external impact, leading to potential detachment of the insulating ceramic layer and misfiring, as the electrodes protrude when the burner is removed for cleaning and are made of hard, heavy materials.
Innovation Solution
A gas stove design featuring a cover plate with a first ignition electrode opening, a connection base with a receiving part for the electrode, and a spring device between the electrode connecting part and the base, which reduces the risk of damage to the ceramic layer by absorbing external impact forces, using a compression spring for stability and ease of production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
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
Solution Approach 1:
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.
Solution Approach 2:
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.
2Temperature
If heavy metal burners are used to ensure durability under high temperatures, then thermal stability is improved, but the weight increases and may cause damage to the insulating ceramic layer
Solution Approach 1:
The spring device provides beforehand cushioning against the heavy weight of metal burners. When the burner is installed, the spring device is compressed and stores elastic potential energy, creating a cushioning effect that absorbs impact forces when the burner is placed or moved, preventing damage to the ceramic insulating layer from the heavy metal components.
3Strength
If the ignition electrode is made with hard materials for durability, then strength is improved, but the risk of ceramic layer detachment under external impact increases
Solution Approach 1:
The spring device provides beforehand cushioning that compensates for the brittleness of hard ceramic materials. While the ceramic layer maintains its strength for normal operation, the spring device absorbs external impact forces before they can cause catastrophic failure or detachment of the ceramic insulating layer.
