Solution Overview
Problem
Conventional refrigerators lack the ability to charge mobile devices without compromising their insulation performance and aesthetics, and they cannot charge devices without built-in wireless charging functionality.
Innovation Solution
A refrigerator with a wireless charging module integrated into its design, allowing for wireless charging of mobile devices while maintaining insulation performance and aesthetics, and also providing a wired charging option for devices without wireless charging capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless charging module is installed in the refrigerator, then mobile devices can be charged wirelessly, but the insulation performance may deteriorate
Solution Approach 1:
The refrigerator body is divided into separate modules: an insulating cabinet body and a wireless charging module that can be independently installed or removed. This segmentation allows the charging function to be added without compromising the overall insulation structure of the refrigerator.
Solution Approach 2:
A magnetic shield plate is introduced as an intermediary component between the wireless charging module and the refrigerator's insulating wall. This shield plate prevents electromagnetic interference while maintaining the insulation performance of the refrigerator body.
2Adaptability or versatility
If a wireless charging module is installed in the refrigerator, then battery charging function is added, but the appearance design may be altered
Solution Approach 1:
The wireless charging module is designed to be nested within the refrigerator's existing structure, specifically utilizing the cabinet cover area. This nesting approach allows the charging function to be integrated without adding external components that would alter the refrigerator's appearance.
Solution Approach 2:
A magnetic shield plate serves as a mediator that can be installed on the refrigerator surface to provide wireless charging functionality while maintaining the original aesthetic appearance of the refrigerator exterior.
3Adaptability or versatility
If the refrigerator structure is modified to accommodate charging functions, then mobile devices can be charged, but the device complexity increases
Solution Approach 1:
The refrigerator's cabinet cover is designed to serve multiple functions: it acts as both the refrigerator's structural component and as a mounting surface for the wireless charging module. This multi-functionality reduces the need for additional separate components and simplifies the overall device structure.
