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

VSEngineering 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

Engineering Contradiction:
Improvedoor handling speedVSAvoidtransport means circulation efficiency
Core Design Contradiction:
SpeedVSProductivity

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Speed

If vertically opening doors are used, then rapid handling is achieved, but fixed rails for internal transport cannot pass through

Engineering Contradiction:
Improvedoor handling speedVSAvoidrail passage capability
Core Design Contradiction:
SpeedVSAdaptability or versatility

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If conventional door alignment methods are used, then manufacturing is simpler, but door tilt and alignment adjustments are limited

Engineering Contradiction:
Improvedoor assembly simplicityVSAvoidalignment and tilt adjustment
Core Design Contradiction:
Ease of manufactureVSEase of operation

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.

Inventive Principle:
Principle #15Dynamics
