Rollable Door with Linear Guides for Rapid Industrial Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current door systems for industrial plants are slow to open and close, particularly sliding and swinging doors, which impede the rapid movement of transport means like forklifts, and vertically opening doors do not allow passage for internal transport rails.
Innovation Solution
A rapid horizontally opening rollable door with linear guides, featuring a fixed horizontal crosspiece, a suspended support with a swivel joint and adjustable stop device, allowing vertical and tilt adjustments, and recesses for transporter rails, enabling quick operation and passage of transport rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If sliding or swinging doors are used for industrial plant openings, then the basic function of separating compartments is achieved, but the handling speed becomes slow and impedes transport means circulation
Solution Approach 1:
The door system employs a dynamic design where the door leaf transitions from a stationary hinged configuration to a mobile rolled-up state. The door can be rapidly rolled up into the upper crosspiece structure, transforming its spatial configuration dynamically to achieve fast opening/closing while maintaining compartment separation when needed.
Solution Approach 2:
The door system utilizes vertical space by rolling the door leaf upward into the crosspiece structure above the opening, rather than swinging it horizontally. This dimensional transition from horizontal to vertical storage resolves the conflict between fast handling and space utilization.
2Speed
If vertically opening doors are used, then rapid handling is achieved, but fixed rails for internal transport cannot pass through
Solution Approach 1:
The door system incorporates recesses that segment the door leaf structure, creating passageways for rails. The door is divided into sections that can accommodate rail passages while maintaining the overall door function, allowing both rapid handling and rail traffic to coexist.
Solution Approach 2:
The door system serves multiple functions simultaneously: it provides rapid opening/closing for fast handling, maintains compartment separation when closed, and allows rail passage through integrated recesses. This multi-functionality resolves the contradiction between speed and adaptability.
3Ease of manufacture
If conventional door alignment methods are used, then manufacturing is simpler, but door tilt and alignment adjustments are limited
Solution Approach 1:
The door system incorporates adjustable components that allow dynamic modification of the door leaf position and tilt after installation. The linear guides and support structures enable operational adjustments without requiring complex manufacturing or reassembly, resolving the contradiction between manufacturing simplicity and operational flexibility.
