Solution Overview

Problem

Conventional cooktop frame manufacturing requires expensive materials with high elongation and large-sized molds, increasing production costs and material waste due to the need for a drawing process.

Innovation Solution

The cooktop frame is manufactured using miniaturized molds and stainless steel sheets with lower elongation, processed into two separate frames without the drawing process, reducing material waste and mold costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a drawing process is used to form the frame, then the frame shape can be formed, but expensive materials with high elongation are required and large-sized molds are needed, increasing manufacturing cost

Engineering Contradiction:
Improveframe shapeVSAvoidmanufacturing cost
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The frame is divided into multiple separate components (side frames and top frame) that are manufactured independently using pressing processes with miniaturized molds, then assembled together. This segmentation eliminates the need for a single large mold and complex drawing process, reducing both mold costs and material requirements while maintaining the overall frame shape.

Inventive Principle:
Principle #1Segmentation

2Shape

If a drawing process is used to form the frame, then the frame can be formed, but material waste increases due to the requirements of the process

Engineering Contradiction:
Improveframe shapeVSAvoidmaterial waste
Core Design Contradiction:
ShapeVSLoss of substance

Solution Approach 1:

The frame components are pre-formed using pressing processes with miniaturized molds that closely match the final component shapes, minimizing material waste from the outset. The notching and piercing operations are performed on smaller, more efficiently shaped materials rather than requiring excessive material for a large drawing mold.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If miniaturized molds are used, then manufacturing cost decreases, but the frame structure must be redesigned

Engineering Contradiction:
Improvemanufacturing costVSAvoidframe structure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The frame is segmented into multiple components (side frames and top frame) that can each be manufactured using miniaturized molds. This segmentation, while requiring assembly, enables the use of smaller, more cost-effective molds and materials, with the overall structural integrity maintained through proper connection design.

Inventive Principle:
Principle #1Segmentation
