A white appliance with a wireless connection module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless connection modules in white appliances like refrigerators are adversely affected by other electronic components, leading to signal interference and increased production complexity and cost when installed on the door.
Innovation Solution
A mounting slot is integrated into the door of the appliance, housing a wireless connection module with a centering pin and mounting tabs, allowing secure placement and minimal interference, thus simplifying production and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless connection module is positioned on the door of the white appliance, then signal interference from other electronic components is minimized, but the production process becomes more complex and production costs increase
Solution Approach 1:
The wireless connection module is nested within the mounting slot that is already integrated into the door structure. The mounting slot serves as a pre-formed cavity that houses the wireless module, eliminating the need for separate mounting structures and reducing production complexity while maintaining optimal signal position
2Reliability
If the wireless connection module is positioned on the door of the white appliance, then signal interference from other electronic components is minimized, but additional space and structural modifications are required on the door
Solution Approach 1:
The mounting slot is designed as a pre-formed feature in the door structure, created during the door manufacturing process itself. This preliminary action eliminates the need for post-production modifications and simplifies the overall manufacturing workflow by integrating the wireless module housing into the original door fabrication
3Device complexity
If the wireless connection module is positioned inside the white appliance body, then production is simpler, but signal interference from other electronic components increases
Solution Approach 1:
The wireless connection module is extracted from the main appliance body and relocated to the door structure. This separation removes the wireless module from the interferential environment of other electronic components while maintaining production efficiency through the integrated mounting slot design
