Solution Overview
Problem
Existing electric devices face challenges in individually regulating temperature across multiple accommodation sections, experiencing temperature deviations due to changes in refrigerant flow rate when tilted or when cooling multiple sections simultaneously, and struggle with compressor load and inefficient cooling of circuits and accommodation of additional items.
Innovation Solution
The electric device features separate cooling mechanisms for each accommodation chamber, located on the side surfaces, along with a detachable partition plate and efficient refrigerant pipe design to maintain temperature control and reduce compressor load, and includes a storage compartment for additional items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a plurality of accommodation sections is cooled by one compressor, then the device complexity is reduced, but the temperature control accuracy deteriorates due to refrigerant flow rate changes when tilted or when cooling multiple sections simultaneously
Solution Approach 1:
The cooling system is segmented into multiple independent cooling circuits, each with its own compressor (first compressor and second compressor). Each accommodation section has a dedicated cooling circuit that operates independently, eliminating temperature control inaccuracies caused by refrigerant flow rate changes when tilted or when cooling multiple sections simultaneously. This segmentation maintains temperature control accuracy while managing device complexity through modular design.
2Adaptability or versatility
If the set temperatures of a plurality of accommodation sections are set to have temperature differences, then the versatility is improved, but the temperature control accuracy deteriorates as temperatures deviate from set temperatures
Solution Approach 1:
Each accommodation section is equipped with independent heating/cooling means and control systems that operate autonomously. This segmentation allows each section to maintain its set temperature independently without being affected by temperature differences in other sections, thereby achieving both temperature setting flexibility and accurate temperature control simultaneously.
3Measurement precision
If separate cooling mechanisms are provided for each accommodation chamber, then the temperature control accuracy is improved, but the device complexity increases
Solution Approach 1:
The cooling system is segmented into multiple independent cooling circuits with separate compressors for each accommodation section. This segmentation enables precise temperature control in each chamber while managing overall system complexity through modular architecture, where each module can be independently designed, manufactured, and maintained.

AI summary
Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.
