Arch-Top Offset Pivot Hinge Attachment for Consistent Door Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional arch-top pivot doors require a hinging system for smooth operation, which can compromise the aesthetic appeal and insulation quality.
Innovation Solution
A metal attachment that serves as a fabrication template and aesthetic improvement, facilitating the installation of an offset pivot hinge by providing a precise location for the pivot hinge and ensuring consistent gaps between the door and jamb.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional hinging system is used for arch-top pivot doors, then smooth open-and-close operation is achieved, but aesthetic appearance deteriorates due to visible cut outs and inconsistent gaps
Solution Approach 1:
A metal attachment component serves as an intermediary element between the pivot hinge and the door structure. This attachment conceals the hinge mechanism from external view while maintaining functional operation, resolving the conflict between operational smoothness and aesthetic appearance by mediating between the mechanical requirements and visual requirements.
Solution Approach 2:
The invention extracts the visible portions of the hinge system from the external view by enclosing them within the metal attachment. The attachment takes out the aesthetic-deficient elements (visible cut outs and hinge components) from the visible domain while preserving their functional role in enabling smooth door operation.
2Ease of operation
If a conventional hinging system is used for arch-top pivot doors, then door operation is enabled, but insulation quality deteriorates due to inconsistent gaps between door and jamb
Solution Approach 1:
The metal attachment acts as a mediator that ensures consistent spacing between the door and jamb throughout the opening and closing motion. This consistent spacing maintains proper insulation gaps while still enabling smooth door operation, thus resolving the contradiction between operational ease and energy efficiency.
Solution Approach 2:
The attachment is pre-configured with specific geometric features (arc-shaped cutout, circular cutout, half round profile) that preliminarily establish the correct positioning and spacing relationships before the door operates. This preliminary configuration ensures that insulation gaps are maintained from the start of the opening/closing motion without requiring active adjustment during operation.
3Ease of manufacture
If pivot hinge is installed without a template, then installation flexibility is maintained, but manufacturing precision deteriorates due to incorrect drilling location
Solution Approach 1:
The metal attachment serves as a pre-fabricated template that incorporates all the necessary geometric information for correct hinge installation. By attaching this template first, the subsequent drilling operation automatically achieves precise positioning without requiring complex measurement and calculation procedures, thus maintaining both ease of manufacture and high precision.
Solution Approach 2:
The attachment embodies a copied or transferred version of the ideal hinge positioning geometry. Rather than calculating positions directly on the door, the attachment provides a physical copy of the correct positioning relationships, which can be directly transferred to the final installation through simple alignment and marking operations.
