Burner Electric Wire Routing Through Intake Pipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional burners face issues with electric wire damage and overheating during transportation and use, leading to reduced lifespan and increased manufacturing costs due to the need for shield plates to prevent contact and leakage.
Innovation Solution
The electric wire and discharge generating means are routed through the intake pipe, with a ceramic insulator between the core wire and burner head, eliminating the need for additional holes and shield plates, thus reducing manufacturing complexity and cost while protecting the wire from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric wire is arranged outside the intake pipe beside the burner head, then the wire is accessible for connection, but the wire may be caught by external objects and damaged during transportation, and flames may overheat and deteriorate the wire
Solution Approach 1:
The electric wire is routed through the intake pipe, nesting the wire within the existing pipe structure. This protects the wire from external damage during transportation while the intake pipe serves as a protective conduit, eliminating the need for additional shield plates.
2Reliability
If the electric wire is routed through the intake pipe, then the wire is protected from damage and overheating, but the wire routing becomes more complex
Solution Approach 1:
The intake pipe serves dual functions: as a structural component for gas/air supply and as a protective conduit for the electric wire. This multi-functionality simplifies the overall device by eliminating the need for separate wire protection structures.
3Reliability
If ceramic insulators are used to close through holes to prevent short-circuiting and leakage, then short-circuiting and gas leakage are prevented, but manufacturing steps are complicated and manufacturing cost increases
Solution Approach 1:
The insulator is extracted from the through hole and repositioned between the core wire and burner head. This eliminates the need to close the through hole with a ceramic insulator, simplifying manufacturing while maintaining electrical insulation and preventing gas leakage through the redesigned wire routing path.
Applied Scientific Principles

Function Achieved in This Case
This configuration prevents wire damage and overheating, extends the lifespan of the burner, and simplifies manufacturing by eliminating the need for shield plates, while maintaining reliable ignition.
Implementation Method 1
Some of these burners include means for generating electric discharge such as a piezoelectric element so that gas can be readily ignited
Implementation Method 2
ceramic insulators 13 are used to close the through holes 12, thereby preventing short-circuiting
Implementation Method 3
a burner head wherein liquefied gas in the gas cylinder is vaporized and burned at the burner head
Implementation Method 4
Gas in the cylinder B is fed into the housing 1. This burner further includes a burner head 4 mounted to the housing through an intake pipe 3. The gas fed into the housing 1 is supplied to the burner head 4 after being mixed with air taken in through an air inlet port 5

AI summary
The object is to prevent damage to and overheating of an electric wire for electric discharge/ignition of a burner, thereby increasing its life, without increase in cost. The burner includes a housing 1, an intake pipe 3 and a burner head 4. Gas in the housing 1 is supplied to the burner head 4 through the intake pipe 3. An electric wire 8 extends through the intake pipe 3 which connects a piezoelectric element 7 to a core wire 10 from which electric discharge is generated near burner ports 9 of the burner head 4 by the piezoelectric element 7. Since the wire 8 is not exposed to outside the intake pipe 3, the wire 8 is never caught and damaged by an external object. Since air-gas mixture which is kept at around the room temperature is flowing through the intake pipe 3, the wire 8 is less likely overheat during use of the burner. Thus, it is not necessary to provide the wire 8 with a shield plate for protecting the wire 8. This simplifies the manufacturing steps and thus reduces the manufacturing cost.
