Primary Door Molding With Rotatable Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secondary door systems require specialized installation skills, can be aesthetically mismatched when primary and secondary doors come from different manufacturers, and lack versatility in functionality to appeal to a wide range of consumers.
Innovation Solution
A door system with a primary door molding that includes rotatably engageable elements and mounting adapters, allowing for adjustable attachment to a primary door frame without a separate secondary door frame, enabling easy installation and adjustment of a secondary door panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate secondary door frame is used, then the secondary door can be properly supported and aligned, but the installation complexity increases and requires specialized skills
Solution Approach 1:
The patent combines the secondary door support function directly into the primary door molding structure. The molding includes integrated hinge members and rotatably engageable elements that eliminate the need for a separate secondary door frame, thereby reducing installation complexity while maintaining proper support and alignment
Solution Approach 2:
The primary door molding is designed to perform multiple functions: it provides the aesthetic finish for the primary door, structural support, and integrated mounting mechanisms for the secondary door. The molding includes hinge members, rotatably engageable elements, and mounting adapter channels that enable the secondary door to be properly supported and aligned without requiring a separate frame structure
2Adaptability or versatility
If primary and secondary doors are produced by different manufacturers, then product selection flexibility increases, but aesthetic matching becomes difficult
Solution Approach 1:
The standardized molding design with universal mounting interfaces allows it to work with secondary doors from different manufacturers while maintaining aesthetic consistency. The molding serves as a common platform that can accommodate various secondary door configurations and styles
Solution Approach 2:
The molding includes adjustable mounting adapter channels that can accommodate different secondary door dimensions and configurations. The rotatably engageable elements can be positioned at different vertical spacings to match various door heights and styles, enabling aesthetic matching across different manufacturer products
3Reliability
If traditional secondary door systems are installed, then proper door functionality is achieved, but installation time and skill requirements increase
Solution Approach 1:
By integrating the secondary door mounting mechanisms into the primary door molding, the patent eliminates the need for separate frame installation, hinge attachment, and alignment procedures. The molding includes pre-configured rotatably engageable elements and mounting adapter channels that simplify the installation process while maintaining proper door functionality
Solution Approach 2:
The molding includes self-aligning features and standardized interfaces that enable easy installation without requiring specialized skills. The rotatably engageable elements and mounting adapters are designed to automatically align with the secondary door, reducing installation time and eliminating the need for expert installers
