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

VSEngineering 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

Engineering Contradiction:
Improvewireless communication signal qualityVSAvoidproduction process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #7Nested doll (Nesting)

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

Engineering Contradiction:
Improvewireless communication signal qualityVSAvoiddoor production simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

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

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveproduction process simplicityVSAvoidsignal interference
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

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

Inventive Principle:
Principle #2Taking out (Extraction)
