Drawer Height Adjustment Mechanism With Flexible Guide-Rail Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for adjusting the height of a drawer require tools or excessive force, limiting convenience and adjustment range.
Innovation Solution
A device comprising a flexible base with a supporting seat and adjusting member connected to a guide rail, allowing for tool-free and force-efficient height adjustment of a drawer by forming an inclined guiding surface, using a screw rod and connecting member to engage with the drawer's recess.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screw driver or eccentric member is used to operate the height adjustment device, then the height adjustment function is achieved, but the operation becomes inconvenient and requires tools
Solution Approach 1:
The adjusting member is designed to be directly operable by the user without requiring external tools. The threaded hole and adjusting member configuration allows the user to manually rotate and adjust the drawer height by simply turning the adjusting member, making the device self-sufficient and tool-free in operation
Solution Approach 2:
The invention extracts and eliminates the need for eccentric members and screw drivers from the adjustment mechanism. By using a simple threaded hole configuration with an adjusting member, the complex eccentric component is removed entirely, simplifying both the structure and the operation while maintaining the height adjustment function
2Adaptability or versatility
If an eccentric component is used for height adjustment, then some adjustment capability is provided, but the adjustment range is very limited
Solution Approach 1:
The base is designed with flexibility allowing it to deform and form an inclined guiding surface when the second end is higher than the first end. This dynamic adaptation enables the drawer to be positioned at various heights and angles, significantly expanding the adjustment range beyond fixed mechanical components
Solution Approach 2:
The invention changes the physical state of the base from rigid to flexible, allowing it to deform and create different configurations. This parameter change enables continuous adjustment of the drawer height and angle by simply deforming the base, providing versatile adaptation without complex mechanical structures
3Ease of operation
If a flexible base is used to form an inclined guiding surface, then tool-free adjustment is enabled, but the structural complexity increases
Solution Approach 1:
The base is segmented into distinct functional zones: a first end for connection to the guide rail, a second end for supporting the drawer, and intermediate portions that can deform. This segmentation allows the base to maintain structural integrity at connection points while enabling controlled deformation in the intermediate regions for height adjustment
Solution Approach 2:
The invention merges multiple functions into the flexible base: it serves as both the structural support element and the adjustment mechanism. The base simultaneously provides structural support, forms the inclined guiding surface for alignment, and enables height adjustment through deformation, eliminating the need for separate adjustment mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy, tool-free, and force-efficient adjustment of the drawer's height without the need for screws or eccentric components, improving usability and adjustment range.
Implementation Method 1
The base has flexibility so that the second end is deformed relative to the first end. When the second end is higher than the first end, an inclined guiding surface is formed between the first and second ends.
Implementation Method 2
The adjusting member has an adjusting portion which is exposed from the transverse hole of the supporting seat. A screw rod extends through the upright hole of the supporting seat and is connected to the threaded hole of the adjusting member and the guide rail.

AI summary
A device for adjusting height of a drawer is disposed on the drawer (60) and a rear portion of a guide rail (52). The device includes a base (10), a supporting seat (12), an adjusting member (14), a screw rod (16) and a connecting member (18). The base (10) includes a first end (20) and a second end (22) which is located in opposite to the first end (20). The first end (20) of the base (10) is connected to the guide rail (52) and the supporting seat (12) is mounted on the second end (22) of the base (10). The screw rod (16) is connected to the adjusting member (14) and extends through the supporting seat (12). The screw rod (16) is also connected to the guide rail (52). The connecting member (18) is connected to the drawer (60) and has a pin (48). When the drawer (60) is mounted on the guide rail (52), the pin (48) is connected to the supporting seat (12). When the adjusting member (14) is rotated, the supporting seat (12) and the connecting member (18) are movable, so that the height of the drawer (60) relative to the guide rail (52) can be adjusted.
