Integrated Cable Clip for High-Voltage Ignition Line Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing domestic appliances, particularly gas-heated cooking appliances, face challenges in securely routing electrical lines to prevent damage from burrs on sheet metal components and ensuring safe separation from hot and electronic components, especially when dealing with high-voltage ignition systems.
Innovation Solution
The electrical lines are secured using sheet metal line holders created through material-separating processing steps like punching or laser cutting, where the burr is formed on the side away from the electrical line, and the design includes a tab with a rear, middle, and front section to prevent slipping and ensure loose fit, allowing movement while maintaining insulation integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If resilient plastic clips are used to secure electrical lines, then the lines can be positioned and secured, but the clips represent separate components that must be pre-assembled and may be damaged or lost during transport
Solution Approach 1:
The patent combines the line holder function directly into the load-bearing component by forming an integrated tab structure through material-separating processing. This eliminates the need for separate resilient plastic clips and their associated assembly steps, while providing secure electrical line positioning as part of the structural component itself
2Area of stationary object
If electrical lines are routed close to electronic components, then space is saved, but the lines may interfere with electronic components through electrical or electromagnetic fields
Solution Approach 1:
The patent uses the load-bearing component with its integrated tab structure as an intermediary barrier between electrical lines and electronic components. This physical separation structure ensures that electrical lines remain at a safe distance from sensitive electronics while still being securely positioned within the appliance housing
3Area of stationary object
If electrical lines are routed close to hot components, then space is saved, but the insulation of the lines may be damaged
Solution Approach 1:
The load-bearing component with its integrated tab serves as a thermal barrier and intermediary structure that positions electrical lines away from hot components such as gas burners. This ensures adequate thermal clearance is maintained while still providing secure line positioning within the compact appliance space
4Ease of manufacture
If material-separating processing steps are used to create line holders, then simple integration is achieved, but burrs may be formed on the sheet metal that could damage electrical lines
Solution Approach 1:
The patent acknowledges that burrs will form during material-separating processing but converts this potential harm into a beneficial feature by orienting the burrs away from the electrical line contact area. The tab geometry is specifically designed so that the rough burr surfaces face away from where the electrical line makes contact, eliminating damage risk while maintaining manufacturing simplicity

AI summary
The appliance has a supporting component (8) made from a metal sheet. A conductor holder (13) determines a position of an electrical conductor (12) at the supporting component. The conductor holder is formed as a single piece at the supporting component. The electrical conductor is subjected with high voltage. A gas burner is fastened to the supporting component. The electrical conductor serves as an ignition line for the gas burner. The conductor holder is designed in a form of a plate (19). The electrical conductor is arranged in an area of a central section (17) of the plate.
