Multiple Door With Parallel Drums and Integrated Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fast closing doors in industrial settings require additional external closure elements for security at night, leading to increased space usage and installation costs due to duplicated support structures and lack of efficient maintenance access.
Innovation Solution
A multiple door system with parallel aligned drums and integrated guides within a single support structure allows for efficient winding and maintenance of multiple closure elements, reducing material usage and space requirements, with optional horizontal displacement and synchronized control through a control panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional external closure elements are installed for security at night, then security is improved, but space usage and installation costs increase due to duplicated support structures
Solution Approach 1:
The patent combines the fast closing door and security closure element into a single integrated door assembly. The support structure, guides, and winding mechanisms are shared between both closure elements, eliminating the need for duplicated structures. This merging allows both functions (fast closing and security) to coexist in the same spatial envelope, resolving the contradiction between improved security and reduced space usage
2Reliability
If additional external closure elements are installed for security at night, then security is improved, but installation costs increase due to duplicated support structures
Solution Approach 1:
The integrated door assembly merges the support structures, guides, and control systems for both the fast closing door and security closure element into a single unit. This consolidation reduces the total quantity of materials required, decreases the number of installation steps, and eliminates redundant components, thereby reducing installation costs while maintaining both security functions
3Reliability
If conventional fast closing doors with external closure elements are used, then security closure is achieved, but maintenance accessibility is difficult
Solution Approach 1:
The integrated door assembly is designed with segmented, modular components where the fast closing door and security closure element can be independently accessed and maintained. The winding mechanisms, guides, and actuators are positioned and configured to allow easy access for maintenance personnel, resolving the contradiction between achieving secure closure and maintaining ease of repair

AI summary
This door comprises a structure (1) with pillars (11) and/or longitudinal members (12), two or more parallel drums (31a, 31b) for winding up respective closure elements (32a, 32b), and guides (6a, 6b) for the parallel, guided displacement of said closure elements (32a, 32b). The openings (61a, 61b) of the guides (6a, 6b) are arranged in a stepped fashion for the insertion of the closure elements (32a, 32b) in a consecutive position in accordance with the sequence of arrangement of the respective drums (31a, 31b).
