Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing domestic appliances with cooling air fans and lamps for illumination require additional space and components, limiting the cooling effect, especially during high-temperature pyrolysis operations.
Innovation Solution
A domestic appliance design featuring a main and secondary duct system with an inclined baffle plate in the secondary duct to direct cooling air more effectively towards the lamp, reducing component count and ensuring reliable cooling, even at high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a secondary duct is added to guide cooling air to the lamp, then the cooling effect is improved, but the device complexity and installation space requirements increase
Solution Approach 1:
The patent combines the cooling air duct and the lamp housing into a single integrated structure. The cooling air channel is formed within the housing itself, eliminating the need for separate secondary ducts and reducing component count while maintaining effective lamp cooling.
Solution Approach 2:
The housing serves multiple functions: it provides structural support, guides cooling air through integrated channels, and houses the lamp assembly. This multi-functionality reduces the need for additional components like separate secondary ducts.
2Temperature
If more components are added to improve cooling, then the cooling effect is enhanced, but the device complexity increases
Solution Approach 1:
The cooling air channel is integrated directly into the housing structure rather than being a separate component. This merging of functions reduces component count while maintaining effective cooling of the lamp during high-temperature operations.
3Temperature
If the duct configuration is made more complex to improve cooling distribution, then the cooling effectiveness increases, but the installation space requirements increase
Solution Approach 1:
The cooling air channels are formed within the housing structure itself, utilizing the existing spatial configuration. This integration achieves effective cooling air distribution to the lamp without requiring additional installation space for separate ductwork.
