Underside Drawer Guide Layout for Wider Furniture Pull-Outs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional furniture pull-outs with drawer guides attached to the side walls reduce the interior space, limiting the width of the drawers and increasing production costs due to the need for specialized guides.
Innovation Solution
The drawer guides are arranged partially or completely on the underside of the drawers, allowing for wider drawers with standard guides, reducing production costs and maintaining the same furniture carcass width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If drawer pull-out guides are attached to the side wall of the furniture pull-out, then the guides are structurally supported, but the interior space of the furniture pull-out is reduced
Solution Approach 1:
The drawer pull-out guides are relocated from the horizontal side wall arrangement to the vertical underside arrangement. This dimensional change allows the guides to be positioned below the drawer rather than beside it, eliminating the space occupation problem on the side walls and maximizing the interior width of the furniture pull-out.
2Length of moving object
If drawer pull-out guides are arranged on the side of the furniture pull-out, then the guides provide stability, but the drawers cannot be built wider
Solution Approach 1:
By moving the guide arrangement from side walls to the underside, the patent enables wider drawer construction while maintaining guide stability through the vertical support structure that extends from the bottom of the drawer assembly.
3Ease of manufacture
If specialized drawer pull-out guides are used for side wall attachment, then the guides provide proper support, but production costs increase
Solution Approach 1:
The underside arrangement of the drawer pull-out guides allows the use of standard commercial drawer guides that serve multiple functions - providing both structural support and smooth operation. These standardized components are widely available and cost-effective, eliminating the need for specialized side-attachment guides.
4Area of stationary object
If drawer rails protrude laterally beyond the drawers, then the guides can be attached to side walls, but the furniture pull-out width increases
Solution Approach 1:
The drawer rails are positioned to extend along the underside of the drawer rather than protruding laterally from the sides. This vertical alignment keeps the furniture pull-out width compact while providing sufficient rail length for proper guide attachment and drawer movement.

AI summary
Furniture pull-out (1) comprising two drawers (10, 20) arranged on top of one another, wherein the two drawers (10, 20) are connected to one another via a common front panel (2) or via a common rear wall (3) or via a common side wall, and two extension guides (11, 21) for the two drawers (10, 20), wherein each of the two drawers (10, 20) is associated with precisely one of the two extension guides (11, 21), wherein the extension guides (11, 21) are arranged on opposite sides of the two drawers (10, 20), wherein the extension guides (11, 21) are arranged at least partially on an underside (12, 22) of the drawers (10, 20).
