Refrigerator with adjustable internal space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerators lack the ability to adjust internal space effectively to accommodate items of different heights, leading to items being either pressed or not securely positioned due to fixed convex grooves with uniform spacing.
Innovation Solution
A refrigerator design featuring a supporting plate with sliding mechanisms, including first and second sliders, a fixing component with springs and sliding sleeves, and a locking system, allowing for adjustable height positioning of the supporting plate to accommodate items of varying heights, along with additional features like a telescopic device and string bag for enhanced storage flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed convex grooves with uniform spacing are used for plate adjustment, then the structure is simple and easy to manufacture, but the internal space cannot be adjusted to meet placing requirements of items with different heights
Solution Approach 1:
The patent transforms the static fixed groove structure into a dynamic adjustable structure by introducing sliders that can move along the connecting plates. The supporting plate's position is no longer fixed but can be dynamically adjusted to different heights by moving the sliders along the connecting plates, enabling adaptation to items of varying heights while maintaining structural simplicity.
Solution Approach 2:
The patent changes the positional parameter of the supporting plate by allowing continuous adjustment along the height direction. Instead of being constrained to fixed discrete positions defined by uniform grooves, the supporting plate's vertical position can be varied continuously or at multiple discrete levels, providing flexibility in space adjustment without complicating the overall structure.
2Ease of operation
If fixed convex grooves with uniform spacing are used, then manufacturing is simple, but items may be pressed due to small space or have nothing to abut against due to too large space
Solution Approach 1:
The dynamic slider mechanism allows users to adjust the supporting plate's position according to the actual height requirements of stored items. This ensures that items always have appropriate support and spacing, preventing both pressing issues (from too small space) and instability (from too large space), while keeping the mechanism simple and easy to operate.
3Adaptability or versatility
If multiple convex grooves with different spacing are added to improve adjustability, then internal space can be adjusted better, but the structure becomes more complex and manufacturing difficulty increases
Solution Approach 1:
Instead of creating complex static groove patterns with varying spacing, the patent employs a simple dynamic mechanism where sliders move along straightforward connecting plates. This approach achieves superior adjustability while maintaining manufacturing simplicity, as the connecting plates can be identical and mass-produced without complex variable-geometry features.
Solution Approach 2:
The patent achieves variable positioning through movement rather than through variable groove geometry. The sliders can be positioned at different locations along the connecting plates, effectively creating adjustable spacing without requiring the manufacturing of complex non-uniform groove patterns, thus simplifying production while enhancing adaptability.

AI summary
Provided is a refrigerator with an adjustable internal space. The refrigerator includes a refrigerator body, a support plate, two first sliders, and a fixing component. Two opposite sides of an inner wall of the refrigerator body in a transverse orientation are fixedly connected with connecting plates, and sides of the connecting plates facing each other both are provided with a first slide groove extending along a height orientation of the refrigerator body. One ends of the two first sliders are respectively mounted in two first slide grooves and can slide in the first slide grooves, and the first sliders define a first clamping hole along a thickness orientation thereof. Two sides of the support plate are respectively connected with the other ends of the two first sliders, and the fixing component is configured for fixing the first sliders in the first slide groove. The refrigerator with the adjustable internal space can adjust a space inside the refrigerator body to meet placing requirements of items with different heights.
