Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators have limitations in optimizing the layout and efficiency of cold air generation and circulation between freezing and refrigerating chambers, leading to suboptimal temperature regulation and storage space utilization.
Innovation Solution
The refrigerator design includes separate cold air generation chambers for each chamber, positioned on the uppermost part of the main body, with guide ducts and fans to efficiently circulate cold air, and a machine room between these chambers, allowing for parallel configuration and improved air flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate cold air generation chambers are provided for freezing and refrigerating chambers, then temperature regulation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent divides the cold air generation system into separate chambers for freezing and refrigerating functions. Each chamber has its own evaporator and cold air fan, allowing independent temperature control and optimized cooling performance for each storage space.
Solution Approach 2:
The patent positions both cold air generation chambers at the uppermost part of the main body, utilizing vertical space arrangement. This three-dimensional layout optimizes air circulation paths and reduces interference between the two cooling systems while maintaining compact form factor.
2Volume of moving object
If cold air generation chambers are positioned on the uppermost part of the main body, then storage space is increased, but air flow management becomes more complex
Solution Approach 1:
The patent provides separate cold air generation chambers for freezing and refrigerating functions, with independent air circulation paths. This segmentation prevents air flow interference and allows each system to be optimized independently for its specific temperature requirements.
Solution Approach 2:
The patent positions the machine room between the two cold air generation chambers, serving as an intermediary space that houses compressors and condensors. This arrangement facilitates heat exchange and air flow management while maintaining compact overall structure.
3Volume of moving object
If machine room is positioned between cold air generation chambers, then space utilization is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the refrigerator body into distinct functional modules: cold air generation chambers at the uppermost part, machine room in the middle, and storage chambers below. This modular segmentation simplifies assembly and manufacturing by allowing each module to be produced and tested independently.
Solution Approach 2:
The patent utilizes vertical stacking of functional modules along the height of the refrigerator. By arranging components in the vertical dimension rather than spreading them horizontally, the design maximizes space utilization while maintaining straightforward manufacturing and assembly processes.
