Solution Overview

Problem

Overhead roll-up doors are prone to damage from external elements and impacts, which can compromise their ability to protect the interior of buildings from ambient conditions.

Innovation Solution

The overhead door design includes a first and second row of panels with extruded rails and a seal, providing enhanced structural integrity and sealing capabilities to withstand external impacts and elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional overhead door construction is used, then the door can be manufactured and installed, but it lacks sufficient strength and durability to resist external impacts and elements

Engineering Contradiction:
Improvestrength and durabilityVSAvoidstability and barrier protection
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The door is divided into multiple rows of panels with individual extruded rails, allowing each section to independently withstand impact forces. The segmentation into upper and lower extruded rails with intermediate supports creates modular structural units that distribute stress throughout the door assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door construction combines multiple materials including extruded metal rails, glazing panels, and sealing components to create a composite structure. The extruded rails provide structural strength while glazing panels provide weather resistance, creating a multi-material system with enhanced overall performance.

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If the door structure is simplified, then manufacturing and installation are easier, but the door cannot provide adequate protection against external elements and impacts

Engineering Contradiction:
Improvemanufacturing and installationVSAvoidprotection against external elements
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The door is divided into multiple rows of panels with individual extruded rails, allowing each section to independently withstand impact forces. The segmentation into upper and lower extruded rails with intermediate supports creates modular structural units that distribute stress throughout the door assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door construction combines multiple materials including extruded metal rails, glazing panels, and sealing components to create a composite structure. The extruded rails provide structural strength while glazing panels provide weather resistance, creating a multi-material system with enhanced overall performance.

Inventive Principle:
Principle #40Composite materials

3Illumination intensity

If glazing panels are installed along the door, then aesthetic and light transmission properties are improved, but the glazing is vulnerable to deglazing and displacement from external impacts

Engineering Contradiction:
Improvelight transmissionVSAvoidresistance to deglazing
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

Sealing members are positioned between the glazing panels and the extruded rails to provide an intermediary protective layer. These seals act as mediators that secure the glazing in place while allowing for thermal expansion and contraction, preventing direct stress transmission that could cause deglazing.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The sealing members provide beforehand cushioning for the glazing panels by absorbing and distributing impact forces before they can cause deglazing. The seals are pre-installed in grooves within the extruded rails to create a protective barrier that cushions the glazing against future impacts.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A reinforced overhead door includes an extruded rail extending along a width direction of the overhead door, the extruded rail being defined by an enclosed wall and a cavity therein. The enclosed wall includes a protruding portion defining part of an interior facing surface of the enclosed wall. The door further includes a pair of exterior members and a glazing panel couplable onto the extruded rail. The glazing panel is received on the extruded rail on an exterior side of the protruding portion separate from the protruding portion and the pair of exterior members are coupled exterior to the glazing panel to secure the glazing panel to the extruded rail. The glazing panel is positioned such that the protruding portion and the glazing panel are on the same side of the extruded rail facing away from the ground when the overhead door is mounted and closed.
