Single-Column Vertical Drawer Layout for Full Cupboard Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cupboard pull-outs require two vertical support columns, which impede the maximum utilization of cabinet depth and impair the visual impression by obstructing usable room height and storage space, especially with the upper crossbeam interfering with the storage space and visual aesthetics.
Innovation Solution
A single vertical support column is used, with the upper cabinet body guide connection moved to avoid obstructing crossbeams, allowing shelves to extend from the rear to the front, and utilizing a continuous slot guide or hooks for secure positioning, enabling optimal cabinet depth utilization and improved visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two vertical support columns are provided to hold shelves and cabinet furnishings, then structural stability is improved, but cabinet depth utilization is worsened and visual impression is impaired
Solution Approach 1:
The patent removes the rear vertical support column from the pull-out frame structure, extracting only the necessary front column. This eliminates the space occupation and visual obstruction caused by the rear column while maintaining structural stability through the remaining front column and optimized guide system configuration.
2Stability of the object's composition
If an upper crossbeam connects the vertical columns to provide upper guide, then structural stability is improved, but usable room height is worsened and visual impression is impaired
Solution Approach 1:
The patent eliminates the upper crossbeam connecting the vertical columns by using a single front column design. The upper cabinet body guide is repositioned to connect directly to the front column or cabinet structure, removing the obstructive crossbeam and maximizing usable room height while preserving structural stability.
Solution Approach 2:
The patent repositions the upper cabinet body guide connection from a horizontal crossbeam configuration to a vertical arrangement along the front column or cabinet structure. This dimensional reconfiguration eliminates the height obstruction while maintaining the guiding function through alternative spatial arrangement.
3Adaptability or versatility
If two vertical support columns are used, then shelf support capability is improved, but overall visual impression of the cupboard pull-out is worsened
Solution Approach 1:
The patent removes the rear vertical support column that obstructs the visual field, leaving only the front column visible. This extraction maintains shelf support capability through the remaining column and optimized guide system while significantly improving the clean, unobstructed visual appearance of the pull-out.
4Reliability
If the upper cabinet body guide connection is in the upper head area, then guide function is improved, but storage space is worsened
Solution Approach 1:
The patent repositions the upper cabinet body guide connection from the upper head area down to the upper area of the furniture front or shelf level. This vertical repositioning maintains the guiding function through the front column connection while clearing the upper head area for additional storage space utilization.

AI summary
The drawer has a drawer frame (2) movably arranged in an interior of a cupboard body (1). The frame has a vertically aligned support column (4) connected with a lower drawer frame profile (5). The profile is movably guided into a lower cupboard body guide (6) and is supported at a shelf board (9). The board has a connection for an upper cupboard body guide (8). The connection is provided at the frame such that the connection is seated in a vertical section below the board during a storage position of the frame, so that the drawer exhibits an upper stowage space (10) for stored articles.
