Cooktop Frame Assembly Using Segmented Bending to Reduce Drawing Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooktop frame manufacturing requires expensive materials with high elongation and large-sized molds, increasing production costs due to the need for a drawing process and material wastage.
Innovation Solution
The cooktop frame is formed using SUS 430 stainless steel, processed through cutting, bending, piercing, and joining of multiple sheets without the expensive drawing process, reducing material waste and mold requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a drawing process is used to form the frame, then the frame shape can be formed with high precision, but expensive materials with high elongation are required and large-sized molds are needed, increasing manufacturing cost
Solution Approach 1:
The frame is divided into multiple separate components (side frames and top frame) that are manufactured independently using cutting and bending processes, then assembled together. This segmentation allows each component to be made with simpler, less expensive processes rather than requiring a single complex drawing process with large molds
Solution Approach 2:
Instead of using the conventional approach of forming the frame through a drawing process that requires high-elongation materials and large molds, the patent inverts the approach by using cutting and bending processes on standard stainless steel sheets, which are simpler and less expensive operations
2Manufacturing precision
If large-sized molds are used for the drawing process, then the frame can be formed properly, but the manufacturing space requirement and equipment cost increase
Solution Approach 1:
The frame manufacturing is segmented into multiple smaller operations (cutting individual components, bending each component) rather than forming the entire frame in one large drawing operation. This eliminates the need for large-sized molds and reduces equipment complexity
Solution Approach 2:
Instead of forming the three-dimensional frame shape through a drawing process that requires large molds, the patent uses cutting and bending operations that work with flat sheets in two dimensions, then assembles them into the final three-dimensional structure. This approach requires smaller, simpler equipment
