Solution Overview
Problem
Conventional refrigerators are inconvenient for identifying and retrieving wine bottles due to narrow shelf spacing and lack of illumination, which complicates the storage and retrieval of wine bottles.
Innovation Solution
A refrigerator design featuring extendable shelves with built-in light modules and adjustable support bars to improve visibility and accessibility of wine bottles, allowing for better identification and retrieval by extending the shelf frame forwardly and illuminating bottles below.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the spacing between shelves is reduced to store more wine bottles, then the storage capacity is improved, but the convenience of withdrawing and identifying wine bottles deteriorates
Solution Approach 1:
The shelf is designed to be movable along guide rails, transitioning from a static fixed position to a dynamic adjustable position. This allows the shelf to be extended forward when wine bottles need to be accessed, providing sufficient space for hand insertion and bottle withdrawal, while maintaining compact spacing for maximizing storage capacity when not in use.
Solution Approach 2:
The shelf is extended forward in advance before wine bottles need to be accessed. This preliminary action creates the necessary space for easy withdrawal and identification of bottles, eliminating the need to reach deep into narrow spaces during the actual retrieval operation.
2Quantity of substance
If the shelf spacing is reduced to increase storage capacity, then more wine bottles can be stored, but the ability to identify wine bottles without withdrawing them deteriorates
Solution Approach 1:
The shelf's movable design allows it to be extended forward, bringing wine bottles closer to the user's viewing position. This dynamic adjustment enables clear identification of bottle labels and types without requiring physical withdrawal, while maintaining compact storage spacing when the shelf is in its retracted position.
3Ease of operation
If the shelf is made extendable to improve accessibility, then wine bottles become easier to retrieve, but the device complexity increases
Solution Approach 1:
The shelf structure is divided into modular components: a shelf bracket fixed to the storage space, guide rails for movement, and the shelf body that slides along the rails. This segmentation allows each component to perform its specific function independently, simplifying the overall implementation of the extendable mechanism while maintaining structural integrity.
Solution Approach 2:
Guide rails serve as an intermediary element between the fixed shelf bracket and the movable shelf body. These rails provide a simple mechanical guidance system that enables smooth extension and retraction of the shelf without requiring complex actuators or control mechanisms, thus improving accessibility while minimizing added complexity.
