Compact Self-Closing Slide Assembly With Integrated Dampening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide assemblies for drawers often result in incomplete closure or accidental reopening due to excessive force, leading to damage and increased complexity and bulkiness, which complicates the self-closing mechanism and increases costs.
Innovation Solution
A compact slide assembly with a self-closing mechanism that includes a dampener to control the closing motion, ensuring the inner slide segment automatically moves to a fully retracted position with a predetermined distance from the fully closed position, utilizing a carrier with springs and a dampener to manage the closing force and prevent slamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a self-closing mechanism is added to automatically close the drawer, then the drawer closure reliability is improved, but the device complexity and bulkiness increase
Solution Approach 1:
The self-closing mechanism is nested within the existing slide assembly structure. The carrier is positioned within the channel formed by the outer slide segment, and the dampener is integrated into the carrier assembly. This nesting approach allows the self-closing function to be added without significantly increasing the overall width or complexity of the slide mechanism.
Solution Approach 2:
A carrier is introduced as an intermediary component between the inner and outer slide segments. The carrier carries the dampener and provides a mounting point for the spring mechanism. This intermediary structure simplifies the overall design by consolidating multiple functions (dampening, spring mounting, engagement) into a single component that interfaces with both slide segments.
2Speed
If excessive force is used to close the drawer, then the drawer closes faster, but the drawer structure or slide mechanism can be damaged
Solution Approach 1:
The dampener is positioned to engage with the inner slide segment before the drawer reaches the fully closed position. This beforehand cushioning prevents excessive closing force by gradually reducing the closing speed as the drawer approaches closure, eliminating the risk of slamming and structural damage while maintaining efficient closing speed throughout most of the closing行程.
3Length of stationary object
If the self-closing mechanism is made more compact, then the width dimension is reduced, but the mechanism complexity may increase
Solution Approach 1:
The mechanism utilizes the vertical dimension within the channel rather than expanding horizontally. The carrier moves vertically within the channel formed by the outer slide segment, and the dampener is oriented to provide resistance in the closing direction while occupying minimal horizontal space. This dimensional reorganization achieves compactness without sacrificing functionality.
Solution Approach 2:
Multiple functions are merged into the carrier component: it serves as the mounting structure for the dampener, the engagement point for the spring mechanism, and the interface with the inner slide segment. This consolidation reduces the number of separate components and simplifies the overall mechanism while maintaining the self-closing functionality within a compact width.

Function Achieved in This Case
The solution provides a compact, cost-effective self-closing slide assembly that ensures complete drawer closure without damage, using a dampener to control the closing motion and prevent excessive force, thus maintaining the structural integrity and reducing the overall width of the assembly.
Implementation Method 1
The self-closing mechanism includes a dampener configured to dampen the closing motion of the self-closing mechanism
Implementation Method 2
A pin is carried by the carrier and is rotatable relative to the carrier. A pair of springs urges the carrier in the closing direction

AI summary
A slide assembly with a self-closing mechanism that includes a dampening mechanism. In one arrangement, the slide assembly includes an inner slide segment slidably coupled to an outer slide segment. The self-closing mechanism is configured to move the inner slide segment towards a retracted position when the inner segment is moved to within a predetermined distance from the retracted position. The slide assembly can also include a latch which is engaged during the closing process and functions to trigger the self-closing and dampening. In an arrangement, the slide assembly has a maximum width dimension of about 0.4 inches or less, taking into account normal manufacturing variations. In an arrangement, a movable portion of the self-closing mechanism slidably engages a bearing race of the outer segment.
