Support rail for a drawer bottom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawer base support rails require a thick design to accommodate different drawer bottom thicknesses, which reduces the storage space height and usable volume due to their thickness.
Innovation Solution
The support rail features tabs on its horizontal and vertical webs, allowing for non-positive fastening of drawer bottoms with varying thicknesses, including those with stepped folds, enabling flexible attachment without compromising stability or increasing the storage space height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the drawer base is dimensioned relatively thickly to prevent breaking under heavy loads, then the strength and reliability are improved, but the storage space height and usable volume are reduced
Solution Approach 1:
The drawer base is divided into two distinct parts: a thick load-bearing central area that provides structural strength, and a thin edge area that minimizes space consumption. This segmentation allows the drawer base to have sufficient strength where needed while maintaining maximum storage space height at the edges.
Solution Approach 2:
Different thicknesses are applied to different regions of the drawer base. The central area has greater thickness for load bearing, while the edge area has reduced thickness to increase storage space height. This local differentiation optimizes both strength requirements and space utilization.
2Adaptability or versatility
If the support rail is designed to accommodate drawer bottoms of different thicknesses using conventional methods, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The support rail incorporates elastically deformable tabs that can dynamically adapt to different drawer bottom thicknesses. These tabs are designed to bend and flex, allowing the same support rail structure to accommodate various thicknesses without requiring multiple specialized designs or complex adjustment mechanisms.
Solution Approach 2:
The support rail uses tabs with varying degrees of elasticity and bendability to adapt to different drawer bottom parameters (thicknesses). By changing the physical state of the tabs from rigid to flexible during attachment, the support rail can accommodate a range of thickness values without increasing structural complexity.

Function Achieved in This Case
This solution allows for increased storage space height by enabling the attachment of drawer bottoms with stepped folds, allowing the top of the drawer to be lowered by 8 mm compared to conventional designs, thus enhancing the usable volume without sacrificing stability.
Implementation Method 1
at least one of the webs, the horizontal web and the vertical web for fastening the drawer base each have at least one tab which can be bent towards the drawer base
