Solution Overview
Problem
Existing refrigerators face challenges in making spherical ice due to the design of the refrigerator and the refrigerator, including the design of the refrigerator, including the design of the refrigerator, including the design of the refrigerator, including the ice maker, which is not able to produce spherical ice when the refrigerator is installed at an inclined position with respect to the ground, and the refrigerator, which is not able to produce spherical ice when installed at an inclined position due to assembly errors and uneven sealing forces in the ice chambers.
Innovation Solution
The ice maker includes a tray and case with fixing parts that allow for secure coupling of the upper and lower trays, compensating for assembly errors and ensuring equal sealing forces, enabling the production of spherical ice even when the refrigerator is installed at an inclined angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the refrigerator is installed at an inclined position with respect to the ground, then the refrigerator can be installed in various positions, but spherical ice cannot be produced due to assembly errors and uneven sealing forces
Solution Approach 1:
The fixing part includes an inclined surface that is asymmetrically designed to compensate for the inclination of the refrigerator. The inclined surface has a specific angle that matches the refrigerator's inclination angle, allowing the ice maker to be adjusted to maintain proper horizontal alignment for producing spherical ice, while still accommodating various installation positions.
Solution Approach 2:
The fixing part allows for parameter adjustment by providing an inclined surface with a specific angle. This parameter change enables the ice maker assembly to be tilted at the same angle as the refrigerator's inclination, thereby compensating for the inclination error and maintaining proper sealing forces and ice chamber alignment for producing spherical ice.
2Device complexity
If the upper tray and lower tray are coupled without a fixing part, then the structure is simpler, but water leaks through gaps and spherical ice cannot be made
Solution Approach 1:
The fixing part acts as an intermediary component between the upper tray and lower tray. It provides a coupling mechanism that includes a protrusion fitting into a groove, creating a reliable seal that prevents water leakage while maintaining the structural integrity needed for producing spherical ice. The fixing part mediates the connection between trays without requiring complex assembly mechanisms.
3Ease of manufacture
If assembly errors occur due to clearance in assembling actual parts, then manufacturing is easier, but difference in height between links occurs and sealing forces become uneven
Solution Approach 1:
The fixing part includes an inclined surface that is asymmetrically designed to compensate for assembly errors. The inclined surface provides adjustment capability that allows the installer to correct height differences between links and equalize sealing forces, thereby maintaining precision despite clearance in assembled parts.
Solution Approach 2:
The fixing part is designed with built-in compensation features that preliminarily address potential assembly errors. The inclined surface and adjustment mechanisms are pre-configured to allow for equalizing sealing forces before final assembly completion, preventing uneven sealing forces caused by clearance in assembled parts.
