Sliding Cabinet Door Alignment Mechanism for Restoring Parallelism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for aligning sliding cabinet doors often require complex assemblies, manual adjustments beneath the doors, and fail to maintain parallelism due to manufacturing tolerances and varying door weights, leading to aesthetic and functional issues.
Innovation Solution
An adjustable device with a sliding wheel and elastic lamina spring mechanism that allows for easy adjustment from both sides, avoiding manual tool use, and ensures precise alignment of doors with the cabinet body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex adjustable mechanisms are used to restore parallelism, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The patent employs adjustable rails that can be dynamically repositioned vertically along the cabinet shelf, allowing the system to adapt to different door weights and alignment requirements. This dynamic adjustability enables precise parallelism restoration without requiring complex fixed mechanisms for each possible alignment scenario.
Solution Approach 2:
The invention changes the vertical position parameter of the lower rails relative to the upper rails to compensate for door inclination caused by weight variations. By adjusting the rail position parameter, the system restores parallelism between doors of different weights without modifying the door structures themselves.
2Adaptability or versatility
If manual adjustment from beneath the door is required, then adjustment capability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent introduces an intermediary adjustment mechanism located at the rear of the cabinet that connects to the rails. This intermediary device allows operators to make adjustments from the accessible rear side rather than reaching beneath the door, significantly improving ease of operation while maintaining full adjustment capability.
3Weight of moving object
If heavy doors are used, then functionality is improved, but parallelism maintenance deteriorates due to bending effects
Solution Approach 1:
The patent compensates for the bending effect of heavy doors by adjusting the vertical position of the lower rails. The adjustment mechanism allows the rails to be repositioned to counteract the downward bend caused by door weight, thereby maintaining parallelism between heavy doors and the cabinet front.

AI summary
An adjustable device (10), (10') for restoring the parallelism between internal (12) and external (14) sliding doors starting from the lower part of cabinets (16) comprises a wheel (24) for sliding the device itself along an extruded profile (60) and a steel elastic lamina spring (26); the sliding wheel (24) is fixed with a knurled pin (28) to a central support (30) from the opposite sides of which a pair of pins (32) protrudes, aligned horizontally between them. On the sides of the central support (30) respective side supports (34, 36) are arranged in which is housed, without possibility of longitudinal excursion, a worm screw (54) cooperating with an insert (48) arranged in the same side supports (34, 36), provided laterally with a hole (56) for a handling key (58) of said screw (54).
