Solution Overview

Problem

Conventional high-speed roll-up industrial doors face challenges in automatically realigning and repairing the door panel when it is dislodged from its guides, especially when displaced inside the opening, leading to potential damage and operational inefficiencies.

Innovation Solution

The door panel is sized to fit within the opening, with guides that extend into the passageway and are constructed from resilient materials or designed to collapse and retract, allowing for automated self-repair mechanisms, including movable guides and realignment ramps, to facilitate easy reconfiguration and minimize damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the door panel is made wider than the opening to engage guides on both sides, then the door panel is properly guided during operation, but the door panel cannot be easily realigned if dislodged inside the opening

Engineering Contradiction:
Improveguiding functionVSAvoidrealignment capability
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The guide assembly is designed with movable components that can dynamically adjust their position. The guide can move between an engaged position (protruding into the passageway to guide the door panel) and a retracted position (not protruding to allow easy realignment). This dynamic capability resolves the contradiction by providing both reliable guiding during operation and ease of repair when dislodged.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The effective width of the guide assembly changes based on its position. When in the engaged position, the guide protrudes into the passageway, effectively reducing the passageway width to guide the door panel. When in the retracted position, the guide does not protrude, effectively increasing the passageway width to allow easy realignment of the door panel. This parameter change resolves the contradiction between guiding function and realignment capability.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the guide assembly protrudes into the passageway to guide the door panel, then the door panel is properly guided, but the passageway width is reduced and vehicles may collide with the guide

Engineering Contradiction:
Improveguiding functionVSAvoidcollision risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The guide assembly is designed to dynamically change its position based on operational needs. It protrudes into the passageway when the door is stationary or moving slowly to provide guiding function, and retracts when the door is opening or closing to allow vehicle passage. This dynamic positioning reduces collision risk while maintaining guiding reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide assembly periodically changes its position between protruding and retracted states synchronized with the door's operation cycle. It protrudes during door stationary periods for guiding, and retracts during door movement periods to allow safe vehicle passage. This periodic action resolves the contradiction between guiding function and collision risk.

Inventive Principle:
Principle #19Periodic action

3Loss of time

If the door panel is quickly retracted for realignment, then repair time is reduced, but the door panel may be damaged during the gesticulations required to repair

Engineering Contradiction:
Improverepair timeVSAvoidpanel integrity
Core Design Contradiction:
Loss of timeVSStrength

Solution Approach 1:

The guide assembly is designed with preliminary realignment features that automatically guide the door panel back into proper alignment as it is being retracted. The guide's geometry and movement path are configured to naturally steer the panel into the correct position, reducing the need for manual gesticulations and minimizing damage risk during the repair process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The guide assembly acts as an intermediary mechanism that facilitates safe realignment of the door panel. As the panel is retracted, the guide's surfaces and structures provide a controlled path that prevents direct impact or harsh manipulation of the panel, thereby reducing damage risk while maintaining quick repair capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention is directed to an industrial high-speed door assembly having a reduced door panel width and having guides for guiding the door which extend into a passageway but are resilient, tough, or resiliently collapsible, to either withstand impacts from vehicle collisions or moveable during opening of the door to avoid collisions while returning for guidance upon closing the door.
