Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a refrigerant pipe is directly contacted with the ice making tray to enable direct-cooling, then cooling speed is improved, but device complexity increases due to the need for precise disposal and fixing of the refrigerant pipe inside the ice making compartment

Engineering Contradiction:
Improvecooling speedVSAvoidinstallation complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The refrigerant pipe is integrated into the ice making tray as a unified structure, eliminating the need for separate disposal and fixing of the pipe inside the compartment. The tray and pipe form a combined assembly that simplifies installation while maintaining direct cooling functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The ice making compartment is divided into an ice making tray assembly (containing the refrigerant pipe) and a driving assembly (containing the auger motor). This segmentation allows the refrigerant pipe to be pre-assembled with the tray, reducing installation complexity while preserving the direct cooling benefit.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the refrigerant pipe is disposed inside the ice making compartment to achieve direct contact with the ice making tray, then cooling efficiency is improved, but ease of repair deteriorates due to difficult access and complex assembly

Engineering Contradiction:
Improvecooling efficiencyVSAvoidmaintenance accessibility
Core Design Contradiction:
ProductivityVSEase of repair

Solution Approach 1:

The ice making compartment is segmented into a removable ice making tray assembly and a driving assembly. The refrigerant pipe is integrated with the tray, allowing the entire tray assembly to be easily removed for maintenance without disassembling the refrigerant pipe connections, thus maintaining cooling efficiency while improving ease of repair.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ice making tray assembly containing the refrigerant pipe is extracted as a separate removable unit from the driving assembly. This allows maintenance personnel to access and service the refrigerant pipe by simply removing the tray assembly, without needing to disassemble the entire ice making compartment, thereby improving maintenance accessibility while preserving cooling efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If multiple components (auger motor, fan, solenoid valve, drain hose) are installed separately in the ice making compartment, then adaptability is improved, but device complexity increases and assembly quality decreases

Engineering Contradiction:
Improvecomponent configurabilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple components (auger motor, fan, solenoid valve, drain hose) are merged into a single integrated driving assembly that can be installed as one unit in the ice making compartment. This reduces assembly complexity and improves assembly quality while maintaining the adaptability of individual component functions through modular design within the integrated assembly.

Inventive Principle:
Principle #5Merging (Combining)
