Frame for a drawer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawer frame designs require a large construction width, making it challenging to achieve a narrower design while maintaining functionality and aesthetic versatility.
Innovation Solution
A frame structure comprising an inner shell and an outer shell with sliding guides and a cover strip that integrates both functional and decorative elements, allowing for adjustable design and attachment options without altering the fundamental structure, using guide elements to facilitate sliding mobility between the shells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a conventional frame structure is used, then functional devices can be mounted, but the construction width becomes relatively large
Solution Approach 1:
The frame is divided into an inner shell and an outer shell that are separate components. The inner shell contains functional devices while the outer shell provides structural support and aesthetic appearance. This segmentation allows the frame to achieve a narrower overall width while maintaining all necessary functions through the coordinated design of the two shells.
Solution Approach 2:
The inner shell is nested within the outer shell, with the inner shell positioned inside the cavity formed by the outer shell. This nesting arrangement allows functional components to be housed within the inner shell while the outer shell provides structural support, achieving a compact narrow profile without sacrificing functional capacity.
2Length of stationary object
If the frame structure is fundamentally changed to achieve narrower design, then construction width is reduced, but aesthetic and functional variants become more difficult to realize
Solution Approach 1:
The outer shell serves multiple functions: it provides structural support, defines the narrow aesthetic profile, and acts as a mounting surface for decorative strips or function strips. The inner shell universally houses various functional devices. This multi-functionality allows different design variants to be achieved by simply changing strips or device configurations rather than fundamentally redesigning the frame structure.
Solution Approach 2:
The frame design allows for easy modification and adaptation. Decorative strips or function strips can be attached to the outer shell, and functional devices can be mounted on or in the inner shell, enabling the frame to dynamically adapt to different aesthetic and functional requirements without requiring fundamental structural changes.
3Strength
If sliding guides are formed directly between inner and outer steel shells, then structural integrity is maintained, but design effort and complexity increase significantly
Solution Approach 1:
Guide elements are introduced as intermediary components between the inner and outer shells to facilitate sliding movement. These guide elements are attached to one shell and engage with corresponding features on the other shell, enabling smooth relative movement while maintaining structural integrity. This intermediary approach simplifies the overall design compared to forming complex sliding surfaces directly on the steel shells.
