Drawer back panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drawer rear walls made of sheet steel or extruded aluminum require significant material, increasing weight and production costs due to the need for substantial material thickness for stability, while maintaining compatibility with existing attachment systems.
Innovation Solution
Designing the drawer rear wall with fastening sections having a greater wall thickness than the central section, achieved through bending or profiling processes, and using a separate mounting device for the thinner central section to connect to existing fastening systems, allowing for reduced material consumption and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a uniform wall thickness is used throughout the drawer back panel to ensure structural stability, then the stability and strength are improved, but the material consumption, weight, and manufacturing costs increase
Solution Approach 1:
The drawer back panel employs different wall thicknesses in different regions: the fastening sections have a first wall thickness optimized for structural stability and connection strength, while the central section has a second, smaller wall thickness sufficient for its load-bearing function. This local differentiation allows each region to have the minimum necessary thickness, reducing overall material consumption while maintaining required strength and stability.
2Quantity of substance
If a smaller wall thickness is used in the central section to reduce material consumption, then the material usage and weight are reduced, but the structural stability and connection strength may be compromised
Solution Approach 1:
The patent applies local quality by specifying that the central section has a second wall thickness that is smaller than the first wall thickness of the fastening sections, but still sufficient to maintain structural stability for the central region's specific load requirements. This allows material reduction in the central area without compromising overall structural integrity.
Solution Approach 2:
The drawer back panel is segmented into distinct regions with different wall thickness characteristics: fastening sections with greater thickness for connection strength, and a central section with reduced thickness for material efficiency. This segmentation allows optimization of material usage in each zone according to its specific functional requirements.
3Adaptability or versatility
If the fastening sections are designed with greater wall thickness for compatibility with existing fastening systems, then the compatibility and connection strength are maintained, but the overall material consumption increases
Solution Approach 1:
The fastening sections are designed with a first wall thickness that ensures compatibility with existing drawer side panel fastening systems and provides adequate connection strength. However, this greater thickness is applied only locally to the fastening sections rather than uniformly across the entire panel, allowing material reduction in the central section while maintaining fastening system compatibility where required.

AI summary
The invention relates to a drawer rear wall (7) for a drawer (3), comprising a first securing section (14a) for securing the drawer rear wall (7) to a first lateral wall (8) of the drawer (3) and a second securing section (14b) for securing the drawer rear wall (7) to a second lateral wall (9) of the drawer (3), wherein the two securing sections (14a, 14b) of the drawer rear wall (7) are mutually spaced in the longitudinal direction (L) of the drawer rear wall (7) by a central section (14c), and a first wall thickness (W1) of at least one of the two securing sections (14a, 14b), preferably both securing sections (14a, 14b), is greater than a second wall thickness (W2) of the central section (14c).
