Retractable Door and Item Holder Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional retractable item holders installed in walls cannot be closed without exposing the item holder, and their telescopic guides create an unsightly gap between the item holder and the wall surface, affecting aesthetics.
Innovation Solution
A structure featuring a fixed frame with mutually opposite receptacles for a retractable door and item holder, using a system of upper and lower guides and sliders that allows the door and item holder to slide while maintaining concealment and minimizing the gap between the item holder and the floor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If telescopic guides are used to support the retractable item holder, then the item holder can be pulled out and retracted, but the guides create a visible gap between the item holder and the wall surface, deteriorating aesthetics
Solution Approach 1:
The support function is extracted from the telescopic guides and transferred to the recessed structure itself. The guides are reduced to minimal dimensional elements that only define the sliding path, while the recessed wall structure provides the mechanical support, eliminating the visual gap problem
Solution Approach 2:
The item holder is nested within a recessed receptacle in the wall structure. When retracted, the item holder is concealed within the wall recess, and the false frame with abutment surface provides support without requiring visible telescopic guides, creating a clean aesthetic appearance
2Adaptability or versatility
If a retractable item holder is installed at an access, then items can be stored and accessed, but the access cannot be closed without displaying the item holder
Solution Approach 1:
The system is segmented into two distinct receptacles: one for the retractable door and one for the retractable item holder. This allows independent operation of each component, enabling the door to close and conceal the item holder within the wall recess while maintaining access functionality
Solution Approach 2:
The item holder is nested within a recessed receptacle in the wall structure. When the door is closed, the item holder remains concealed within the wall recess, visible only when the door is open and the item holder is extended
3Strength
If telescopic guides with support function are used, then the item holder can be supported, but the baseplate is positioned several centimeters from the wall surface, creating an unaesthetic impact
Solution Approach 1:
The support function is extracted from the telescopic guides and assigned to the recessed wall structure and false frame. The guides are reduced to minimal elements that only define the sliding path, allowing the baseplate to be positioned flush with or very close to the wall surface
Solution Approach 2:
The recessed wall structure serves multiple functions: it provides mechanical support for the retractable mechanisms, conceals the item holder when retracted, and eliminates the need for visible support elements, combining structural and aesthetic roles

AI summary
A structure (1) for retractable sliding doors and the like, comprising a fixed frame (2) which defines two mutually opposite receptacles (4, 5) which are mutually spaced so as to define a central opening (6) which is interposed between the receptacles (4, 5), the receptacles (4, 5) accommodating slideably and respectively a retractable door (7) and a retractable item holder (8) which are designed to be arranged selectively, alternately with each other, at the central opening (6) for the closure thereof or for access to the retractable item holder (8).
