Problem
Electric ranges face challenges in simplifying assembly processes, reducing component count, improving cooling efficiency, ensuring sufficient air intake for blower fans, and preventing sagging of supporting brackets, which affect performance and manufacturing efficiency.
Innovation Solution
The design includes a case with a supporter that separates the air flow path, integrates air blower fans and printed circuit boards, and features a porous structure for air intake and discharge, along with a ribbed design to prevent internal air from entering the fan and support the heating unit, reducing the number of components and manufacturing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bracket is disposed over the electronic components to block the magnetic field or heat, then the electronic components are protected from adverse effects, but the bracket undergoes deflection over time due to the weight of the heater and requires additional support structure
Solution Approach 1:
The patent combines the bracket that blocks magnetic field and heat with the support structure for the heater into a single integrated component. This unified structure eliminates the need for separate support elements, preventing deflection while reducing overall device complexity.
2Reliability
If the air flow path is made smoother, then cooling efficiency is improved, but the area for air intake by the blower fan may be reduced
Solution Approach 1:
The patent designs the air flow path with three-dimensional curvature that guides air smoothly from the intake area through the housing to the blower fan. This spatial routing maintains a large intake area while ensuring smooth flow transition, avoiding turbulence and maximizing cooling efficiency.
3Reliability
If the amount of air drawn into the air blower fan is increased, then cooling efficiency is improved, but the structure for sufficient air intake becomes more complex
Solution Approach 1:
The housing structure serves multiple functions: it provides the air intake path, guides air flow smoothly, and supports the blower fan assembly. This multi-functional design increases air intake capacity without requiring separate dedicated structures for each function.
4Productivity
If the number of components is reduced to simplify assembly, then manufacturing efficiency is improved, but the structural support and air flow management functions may be compromised
Solution Approach 1:
The patent integrates multiple functions into the housing structure, including air intake pathways, support surfaces for electronic components and heater, and mounting structures for the blower fan. This consolidation reduces component count and assembly steps while maintaining all necessary structural and functional requirements.
