Solution Overview
Problem
Existing refrigerators with built-in displays face challenges in simplifying the assembling structure of the door and integrating a sophisticated design while ensuring convenient functions and effective electromagnetic wave transmission.
Innovation Solution
A refrigerator design featuring a display unit mounted on the door with a touch screen display glass, a proximity detection sensor, and a communication module, where the display glass is separated from the door frame to prevent interference with electromagnetic waves, and a fixing member for easy assembly, allowing for a sleek exterior and enhanced user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display glass is attached directly to the door frame, then the assembly structure is simplified, but electromagnetic wave transmission is interfered with
Solution Approach 1:
The display assembly is segmented into separate components: the display glass is detached from direct contact with the door frame, and a fixing member is introduced as an intermediary component. This segmentation allows the display glass to be positioned for aesthetic purposes while the fixing member handles the electromagnetic wave transmission, resolving the contradiction between simplified assembly and electromagnetic wave interference prevention.
Solution Approach 2:
A fixing member is introduced as an intermediary component between the display glass and the door frame. This fixing member serves as a mediator that allows the display glass to be positioned for aesthetic purposes while preventing direct contact that would interfere with electromagnetic wave transmission, thus resolving the contradiction between simplified assembly structure and electromagnetic wave interference prevention.
2Object-affected harmful factors
If multiple components are used for display unit assembly, then electromagnetic wave transmission is prevented, but assembly complexity increases
Solution Approach 1:
The fixing member combines multiple functions into a single component: it attaches the display glass to the door frame, positions the display unit, and prevents electromagnetic wave interference through its conductive mesh structure. This merging of functions reduces the number of separate components needed, thereby simplifying the overall assembly structure while maintaining electromagnetic wave transmission prevention.
Solution Approach 2:
The fixing member is designed with multi-functionality: it serves as both a mechanical attachment component and an electromagnetic shielding component. The conductive mesh structure provides both structural support and electromagnetic wave transmission prevention, allowing a single component to address multiple requirements and reduce assembly complexity.
3Shape
If the display glass is positioned close to the door frame, then a sleek exterior is achieved, but electromagnetic wave transmission is blocked
Solution Approach 1:
The fixing member acts as an intermediary between the display glass and the door frame, allowing the display glass to be positioned close to the door frame for a sleek exterior appearance while the fixing member's conductive mesh structure prevents electromagnetic wave interference. This intermediary solution resolves the contradiction between aesthetic design and electromagnetic wave transmission.
4Adaptability or versatility
If the display unit is integrated into the door, then functionality is enhanced, but manufacturing complexity increases
Solution Approach 1:
The display unit is segmented into separate components (display glass, display module, fixing member) that can be manufactured independently and then assembled. This segmentation allows each component to be optimized for its specific manufacturing process while the overall integration into the door provides enhanced functionality, resolving the contradiction between functionality and manufacturing complexity.
