Drawer Front Adjustment Mechanism Using Eccentric Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer systems face issues with improper assembly tolerance and quality, leading to drawers becoming tilted and failing to fit snugly into the housing, and existing adjusting mechanisms are physically demanding for users.
Innovation Solution
An adjusting device comprising a fixed member, plates, adjusting members, and locking members that allow for angular and positional adjustment of the drawer face panel relative to the drawer housing, enabling easy alignment without manual support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual support and screw fixing is used to adjust the drawer face panel, then the position can be adjusted, but the operation becomes physically demanding
Solution Approach 1:
The adjusting device enables the drawer face panel to be adjusted automatically through the eccentric rotating mechanism. When the eccentric portion rotates, it automatically pushes the drawer face panel to the desired position without requiring the user to manually hold or support the panel, thus reducing physical effort while maintaining adjustability
Solution Approach 2:
The adjusting device introduces a dynamic rotating mechanism with an eccentric portion that converts rotational motion into linear displacement. This dynamic system allows continuous adjustment of the drawer face panel position during rotation, providing smooth and effortless positioning compared to static screw fixing
2Manufacturing precision
If assembly tolerance is great or components are improperly assembled, then the drawers become tilted, but adjusting the angle requires complex manual intervention
Solution Approach 1:
The adjusting device automatically compensates for assembly tolerance issues and tilting problems through its eccentric rotating mechanism. The system self-adjusts the drawer face panel angle and position without requiring complex manual intervention or specialized tools, simplifying the correction of assembly errors
Solution Approach 2:
The adjusting device changes the positional parameters of the drawer face panel through rotation of the eccentric mechanism. By varying the rotation angle, the system can adjust both the position and angle parameters of the drawer face panel, enabling precise alignment correction without complex procedures

AI summary
An adjusting device (10) includes a fixed member (12, 200); first and second plates (14, 16), both connected to the fixed member (12, 200); a first adjusting member (20a); and a first locking member (22a). The fixed member (12, 200) has a first hole (28a, 202) and a window (30). The second plate (16) has first and second contact portions (46, 48). The first adjusting member (20a) has an adjusting portion (52a) contacting against the second contact portion (48) and has an eccentric portion (54a) extending through the window (30) and movably connected to the first plate (14). The first locking member (22a) partially extends through the first contact portion (46) and the first hole (28a, 202) to connect with the first plate (14). The second plate (16) can be displaced relative to the fixed member (12, 200) in response to displacement of the first adjusting member (20a).
