Frame for a drawer having a frame body as well as a drawer and furniture item having a drawer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hollow-chamber frames for drawers are limited in their versatility and require matching with specific drawer guiding systems, restricting their installation height and adaptability.
Innovation Solution
A frame design featuring a cavity with an inner base part and an outer covering element that supports the base part over its length, allowing for a rigid structure with a small installation height and flexibility in design, including a wiper lip for secure connection and adjustable height through attachment elements, enabling the same frame body to be used in various configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hollow-chamber frame is used to accommodate drawer guiding systems, then the installation height can be reduced or maximized, but the frame design becomes limited and requires matching with predetermined drawer guiding systems
Solution Approach 1:
The frame body is designed as a universal component that can accommodate different drawer guiding systems through standardized receiving means. The covering element can be exchanged or adapted to match different guiding system requirements, allowing the same base frame to serve multiple functions and configurations.
Solution Approach 2:
The frame is divided into distinct segments: a standardized frame body with receiving means, and interchangeable covering elements. This segmentation allows the functional base to remain constant while the covering elements can be modified to suit different drawer guiding systems and design requirements.
2Strength
If the covering element fully covers the base part over its length, then a rigid frame body is created, but the installation height increases
Solution Approach 1:
The covering element provides full coverage and rigidity only where structurally necessary, while leaving other areas more compact. The top horizontal portion is supported at several points along the length of the base part which are interrupted by free regions, providing localized reinforcement without uniform height increase throughout.
3Length of stationary object
If the spacing between the covering element and base part is reduced to less than 10 mm, then the installation height is minimized, but the connection stability may be compromised
Solution Approach 1:
A wiper lip is introduced as an intermediary element between the covering element and the drawer bottom. This wiper lip provides a reliable connection interface that maintains stability even with minimal spacing between the covering element and base part, effectively mediating the connection without requiring large clearance.
