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

VSEngineering 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

Engineering Contradiction:
ImprovesecurityVSAvoidspace usage
Core Design Contradiction:
ReliabilityVSArea of stationary object

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
ImprovesecurityVSAvoidinstallation costs
Core Design Contradiction:
ReliabilityVSEase of manufacture

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

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If conventional fast closing doors with external closure elements are used, then security closure is achieved, but maintenance accessibility is difficult

Engineering Contradiction:
Improvesecurity closureVSAvoidmaintenance accessibility
Core Design Contradiction:
ReliabilityVSEase of repair

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

Inventive Principle:
Principle #1Segmentation

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).
