Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional main tilting doors for garage spaces are cumbersome, difficult to assemble, require specialized transport and installation, and are limited by the need for expensive lifting equipment and skilled labor, making them impractical for widespread use.
Innovation Solution
A modular main tilting door design with disassemblable components, including fixed and movable frames, sliding guides, and pulley systems, allowing for easy assembly on site using reduced-size, lightweight parts and automated operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional main tilting doors are assembled in factory using special equipment, then manufacturing precision is improved, but device complexity and weight increase, making transport and installation difficult
Solution Approach 1:
The door system is divided into multiple independent panels (first panel, second panel, third panel, fourth panel) that can be manufactured separately and assembled on-site. Each panel has standardized connection interfaces with the fixed frame, allowing precise assembly without complex factory equipment. The segmentation enables modular construction while maintaining manufacturing precision through standardized components.
2Strength
If traditional main tilting doors are made as single large component, then structural strength is improved, but weight increases and transport becomes difficult
Solution Approach 1:
The door is segmented into multiple lighter panels that can be transported separately. Each panel maintains sufficient structural strength for its size, and the overall door strength is achieved through the coordinated action of multiple panels connected to the fixed frame via hinges and articulation arms.
Solution Approach 2:
Multiple individual panels are combined to form the complete door assembly. The panels work together as a unified structure, with each panel contributing to the overall strength and functionality. The combination of panels with the fixed frame and articulation mechanism creates a structurally sound door system without requiring any single component to be excessively heavy.
3Reliability
If traditional main tilting doors use specialized lifting equipment for installation, then installation reliability is improved, but cost increases and accessibility decreases
Solution Approach 1:
By dividing the door into smaller, manageable panels, the installation process no longer requires specialized lifting equipment. Each panel can be handled by standard installation tools and personnel with basic skills, significantly improving ease of operation while maintaining installation reliability through proper connection mechanisms.
Solution Approach 2:
The door system incorporates self-aligning and self-latching features in its connection mechanisms. The panels automatically position themselves correctly during installation and secure themselves to the fixed frame through the hinge and articulation arm connections, reducing the need for specialized equipment and highly skilled labor.

AI summary
A main tilting door for the closure of an access opening of a room includes two fixed uprights, including vertical sliding guides, and one fixed crosspiece associable with each other to define a fixed frame. The door includes two movable uprights and two movable crosspieces associable with each other to define a movable frame. The door includes tilting movement device/unit/component/apparatus or the like including two lateral supporting arms each having a first end which can be hinged to an intermediate area of the movable uprights and a second end which can be hinged to a top of the fixed uprights; and two sliding supports movable along the vertical sliding guides. The door includes panels associable with the movable frame. At least one of the movable uprights and the movable crosspieces includes a sliding track and cursors movable along the sliding track, the panels associable with the cursors.
