Snap Spring Clip Mounting for Burner Unit Vertical Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring clips for coupling electric burner units with support structures in glass-ceramic cooktops often lack vertical support and are difficult to assemble, especially when coupling points are near horizontal alignment, and may not provide a reliable fit.
Innovation Solution
A spring clip design featuring a retention tab, a resiliently deformable retention arm, and a snap tab that allows for snap-in installation and secure attachment of the burner unit to the cooktop, with a method involving alignment and engagement of the retention tab with the burner unit's housing and snap tab with the cooktop's aperture, providing vertical support and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional springs are used for coupling burner units with support structures, then vertical support may be provided, but assembly becomes difficult requiring extension and assembly of hooked ends
Solution Approach 1:
The spring clip is divided into distinct functional segments: a retention tab portion that engages with the burner unit housing, and a snap tab portion that engages with the support structure. This segmentation allows each part to be independently designed for its specific function, simplifying the overall assembly process while maintaining structural integrity.
Solution Approach 2:
The retention arm is pre-biased in a resiliently deformable state, storing elastic energy that automatically engages the retention tab with the burner unit housing during installation. This preliminary positioning and biasing eliminates the need for manual extension and hooking operations, significantly simplifying assembly.
2Area of stationary object
If coupling points are positioned near horizontal alignment, then space is optimized, but vertical support is lost
Solution Approach 1:
The spring clip extends in multiple dimensions: horizontally to connect coupling points near alignment (optimizing space) and vertically through the resilient retention arm to provide vertical support. The retention arm's vertical deformation capability adds the necessary vertical dimension to the otherwise horizontal coupling arrangement.
Solution Approach 2:
The retention arm's resiliently deformable property allows it to change its vertical parameter dynamically. During assembly and operation, it can deflect vertically to accommodate thermal expansion, vibration, and positioning tolerances, maintaining vertical support even when coupling points are horizontally aligned.
3Reliability
If a secure fit is achieved between burner unit and support structure, then reliability improves, but assembly difficulty increases
Solution Approach 1:
The resilient retention arm automatically adjusts and secures the burner unit to the support structure through its elastic deformation. The spring-loaded mechanism self-regulates the engagement force, ensuring reliable contact without requiring precise manual adjustment or excessive assembly force from the installer.
Solution Approach 2:
The resiliently deformable retention arm changes its physical state during assembly, transitioning from a relaxed state to a compressed or extended state as it engages with the burner unit housing. This parameter change enables the system to achieve a secure, reliable fit through elastic deformation rather than rigid mechanical interference.

Function Achieved in This Case
The spring clip ensures reliable and secure attachment of the burner unit to the cooktop, minimizing vibration and maintaining consistent contact between the burner unit and the glass-ceramic surface, while facilitating easy assembly and disassembly without requiring excessive force.
Implementation Method 1
The retention arm further defines a resiliently deformable section facilitating movement of the lever toward and away from the retention tab
Implementation Method 2
The retention arm further defines a resiliently deformable section biasing the lever against the side wall
Implementation Method 3
The spring clip further includes a snap tab positioned opposite the retention arm from the retention tab and resiliently deflectable toward and away from the retention tab

AI summary
A spring clip for attaching a radiant burner unit to a cooktop includes a retention tab having a portion extending in a first direction and a retention arm defining a lever portion projecting away from the retention tab to an end displaced from the tab in a second direction generally normal to the first direction. The retention arm further defines a resiliently deformable section facilitating movement of the lever toward and away from the retention tab. The spring clip further includes a snap tab positioned opposite the retention arm from the retention tab and resiliently deflectable toward and away from the retention tab.
