Solution Overview
Problem
Conventional refrigerators have difficulty maintaining a stable temperature range for specific goods, leading to quality reduction due to significant temperature fluctuations in storage chambers, which is not adequately addressed by existing technologies.
Innovation Solution
The refrigerator incorporates a temperature adjusting device with a cooling and heating mechanism, an inner guide to partition the storage chamber into separate temperature zones, and a partition member to minimize temperature differences, allowing for independent temperature control of multiple storage spaces with precise temperature adjustments.

1Stability of the object's composition
If a single storage chamber is used in conventional refrigerators, then the structure is simple, but the temperature fluctuates significantly leading to quality reduction of stored goods
Solution Approach 1:
The storage chamber is divided into multiple independent temperature zones using partition members. Each zone can be controlled at different temperatures, allowing stable temperature maintenance for different types of goods simultaneously. This segmentation resolves the contradiction by creating temperature stability through structural division rather than using a single uncontrolled chamber.
Solution Approach 2:
Different regions of the storage chamber are assigned different temperature characteristics through the partition members. Each local zone has optimized temperature control suitable for specific storage needs, achieving overall temperature stability while maintaining structural functionality. This allows the system to provide localized temperature stability without requiring complete structural redesign.
2Manufacturing precision
If partition members are added to create separate temperature zones, then temperature control precision is improved, but the device complexity increases
Solution Approach 1:
The partition members are designed to be movable rather than fixed, allowing dynamic adjustment of zone sizes and configurations. This enables precise temperature control for different storage needs while maintaining operational flexibility. The dynamic design reduces structural complexity compared to fixed multi-chamber systems while achieving the same temperature precision goals.
Solution Approach 2:
The partition members serve multiple functions: they create temperature zones, allow mobility for access, and can be positioned to create different storage configurations. This multi-functionality achieves precise temperature control without proportionally increasing device complexity, as the same structural elements perform multiple roles.
