Frame for a drawer with a frame body and drawer and piece of furniture with a drawer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hollow chamber frames for drawers lack flexibility and design customization, limiting their application and user customization options.
Innovation Solution
A frame design featuring a cavity with an inner base part and an outer shell element that covers the base part over 90% of its length, allowing for a compact and rigid structure with adjustable height and customizable design through interchangeable casing and wall elements, including fastening means and decorative surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hollow chamber frame is designed with a specific drawer guide system, then the drawer guide system can be integrated to save installation height or maximize drawer height, but the frame design becomes limited to specific applications and loses flexibility
Solution Approach 1:
The frame body is designed with a standardized cavity structure that can accommodate different drawer guide systems (front-bearing, side-bearing, underfloor) without requiring frame redesign. The cavity serves multiple functions: housing the guide system, providing mounting surfaces, and maintaining structural integrity across various drawer configurations.
Solution Approach 2:
The frame is divided into modular components: a standardized frame body with cavity, separate drawer guide system, and interchangeable covering elements. This segmentation allows the guide system to be selected and installed independently based on specific application requirements while maintaining a consistent frame structure.
2Strength
If the covering element covers the base part over 90% of its length, then a compact and rigid structure is created, but the design becomes more complex with multiple components
Solution Approach 1:
The covering element is designed to extend over 90% of the base part length, merging the visual and structural functions into a unified appearance. This extensive coverage creates a compact, rigid structure where the covering element and base part work together as an integrated assembly, reducing the need for additional reinforcement components.
3Adaptability or versatility
If the base part has a maximum height of 50 mm, then flexibility for various covering elements is provided, but the support capacity for the drawer guide system is reduced
Solution Approach 1:
The base part is designed with non-uniform thickness distribution: thinner sections (within 50mm height) provide flexibility for different covering elements, while localized reinforcement zones within the cavity provide concentrated support capacity for the drawer guide system. This local quality variation allows both low height and high support capacity to coexist.

AI summary
A frame (18) for a drawer (1) is proposed, with a frame body (5) which has a cavity for accommodating a drawer slide system, the frame body (5) having an inner base part (7) and an outer base part (7 ) enveloping cover element (6), and wherein the inner base part (7) has receiving means (12) for the drawer slide system and a support (7a) for a lower part of a drawer bottom. According to the invention, the covering element (6) completely or almost completely covers the base part at least over its length, with an upper horizontal section (9) of the covering element (6) being supported on the base part (7).
