Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerator designs for ice making compartments lack improved cooling performance and efficient replacement and repair of ice making units, leading to suboptimal cooling efficiency and increased energy loss.
Innovation Solution
The design incorporates an ice making unit with a refrigerant pipe for direct cooling, heat-exchanging ribs, and a fan to enhance air circulation and heat exchange within the ice making compartment, along with a drainage duct system for efficient air flow and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cold air is supplied to the ice making compartment through forced convection from an evaporator, then cooling performance is improved, but energy loss increases and cooling efficiency decreases
Solution Approach 1:
The patent extracts the refrigerant pipe from the traditional evaporator-based forced convection system and places it directly in the ice making compartment. This extraction eliminates the need for complex air circulation and reduces energy loss while maintaining effective cooling.
Solution Approach 2:
The refrigerant pipe acts as a direct thermal intermediary between the refrigeration cycle and the ice making compartment, replacing the indirect air-based heat transfer system. This direct thermal connection improves efficiency by eliminating energy loss associated with air circulation.
2Temperature
If a traditional evaporator system is used for cooling the ice making compartment, then cooling function is provided, but the structure becomes complex and maintenance difficulty increases
Solution Approach 1:
The patent removes the evaporator and associated forced convection components from the ice making compartment, retaining only the essential refrigerant pipe. This simplification maintains the cooling function while dramatically reducing structural complexity and improving maintainability.
3Productivity
If the ice making unit is designed as an integrated component, then cooling efficiency is maintained, but replacement and repair become difficult
Solution Approach 1:
The patent segments the ice making unit into a removable module that can be easily detached and replaced. This modular design allows the ice making unit to be maintained as a complete functional component, preserving cooling efficiency while enabling simple replacement and repair operations.
