Cooking Top Assembly with Reference Positioning to Prevent Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling household cooking tops often result in deformation of heat shields and plates, leading to enamel damage, rust formation, and improper coupling between components, causing aesthetic and functional issues.
Innovation Solution
A method that assembles the cooking top without using fastening means to couple heat shields to the plate, utilizing reference means such as cylinders and tongues to accurately position components without deformation, allowing the cover to be sandwiched between the plate and heat shields, eliminating the need for a jig and preventing damage from drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fastening means are used to couple heat shields to the plate, then the heat shields and plate are securely attached, but deformation occurs leading to enamel damage and rust formation
Solution Approach 1:
The patent removes the fastening means (screws, clips, or other coupling elements) from the assembly process. Instead of coupling the heat shields to the plate through fasteners, the method assembles the cooking top by positioning components relative to each other using reference means, eliminating the need for fastening means that cause deformation and enamel damage.
Solution Approach 2:
The patent introduces reference means (cylinders and tongues) as intermediary elements that facilitate accurate positioning and coupling of components without direct mechanical fastening. These reference means act as mediators that enable precise alignment and stable assembly while avoiding the harmful effects of traditional fastening methods.
2Stability of the object's composition
If fastening means are tightened to secure heat shields and plate, then coupling stability is improved, but deformation occurs causing aesthetic and functional problems
Solution Approach 1:
The patent eliminates fastening means from the assembly process, removing the source of deformation caused by tightening. Stability is achieved through the geometric constraints and reference means rather than mechanical fastening, preventing both deformation and instability.
Solution Approach 2:
The patent replaces the mechanical fastening system (screws, clips, tightening mechanisms) with a reference-based positioning system. Cylinders and tongues provide geometric constraints that ensure stable coupling without applying deforming forces, substituting a deformation-free mechanical approach for the traditional fastening method.
3Manufacturing precision
If a jig is used to assemble components, then positioning accuracy is improved, but device complexity and assembly time increase
Solution Approach 1:
The patent merges the positioning function previously performed by external jigs into the components themselves through integrated reference means. The cylinders and tongues are part of the cooking top components, eliminating the need for separate assembly equipment while maintaining positioning accuracy.
Solution Approach 2:
The components perform their own positioning function through the reference means (cylinders and tongues) that are integral to their design. Instead of requiring external jigs to provide positioning, the components self-position relative to each other during assembly, simplifying the overall assembly process and reducing equipment requirements.
4Strength
If drilling is performed to install fastening means, then secure coupling is achieved, but damage to the cover and aesthetic defects occur
Solution Approach 1:
The patent removes drilling and fastening operations from the assembly process. By eliminating fastening means entirely, there is no need to drill holes in the cover or any other component, preventing both structural damage and aesthetic defects while still achieving secure coupling through reference-based positioning.
