Bottom-Freezer Container Movement for Easier Food Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bottom freezer refrigerators require a convenient and simple method for stowing and retrieving food from the freezing chamber, as the drawer-type door complicates access.
Innovation Solution
A refrigerator container moving system that includes a motor-powered container supporter, a rotary arm, and a rechargeable battery for easy horizontal or vertical movement of the container, allowing for convenient access and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a drawer-type door is used for the freezing chamber in a bottom freezer refrigerator, then the refrigerator structure is compact and space-efficient, but access to and handling of food becomes inconvenient and complicated
Solution Approach 1:
The freezing chamber door is segmented into two independent containers (first container and second container) that can move separately along the door. This allows selective access to individual containers without requiring the user to manually pull out the entire door, thus maintaining compact structure while improving food access convenience.
Solution Approach 2:
The containers are designed to be dynamically movable along the door structure rather than being fixed. The first container can move along the first direction, and the second container can move along the second direction, enabling flexible access and handling of food items while preserving the compact drawer-type door design.
2Device complexity
If manual handling of containers is required in a drawer-type door, then the system is simple, but user convenience and ease of food handling deteriorates
Solution Approach 1:
The system introduces dynamic movement capabilities where the first container moves along the first direction and the second container moves along the second direction. This automated movement reduces manual handling effort while maintaining relatively simple system architecture through the use of guide grooves and basic motor mechanisms.
3Reliability
If containers are fixed in the drawer-type door, then the structure is simple and reliable, but flexibility and convenience of food storage and retrieval deteriorates
Solution Approach 1:
The freezing chamber is divided into multiple independent containers that can move independently. This segmentation allows each container to be optimized for specific storage needs while maintaining overall structural reliability through the door-mounted guide system.
Solution Approach 2:
The containers transition from fixed to dynamically movable positions along defined paths (first direction and second direction). This provides adaptability for different food storage configurations while maintaining reliability through constrained movement paths and guide grooves.
