Hinge Fitting Guide Plate for Miter Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge fittings for window shutters struggle to be securely attached in the area of corners and miters, resulting in unused space and complex constructions to overcome this issue.
Innovation Solution
A hinge fitting with a guide plate that can be clamped between a frame section and a cover plate, featuring a fastening element with a dome and base that can be guided along the frame section up to the miter, allowing for secure attachment without additional complex elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinge fitting is attached to the frame section, then the frame section can be pivotally mounted, but the corner area and miter region cannot be used for attachment
Solution Approach 1:
The fastening element is divided into a base portion and a mandrel portion. The base portion engages with the guide structure in the frame section, while the mandrel portion extends through the cover plate to provide pivotal mounting. This segmentation allows the hinge fitting to be positioned at various locations along the frame section, including near corner joints and miters, without interfering with the structural connections.
Solution Approach 2:
The fastening element utilizes the depth dimension of the frame section by extending the mandrel through the cover plate thickness. This allows the hinge fitting to be positioned at different locations along the frame's length while maintaining secure attachment, effectively utilizing the third dimension (depth) to overcome the limitation of the front-side guide structure.
2Area of stationary object
If the hinge fitting is positioned near the corner or miter, then more frame length becomes usable, but the construction becomes more complex
Solution Approach 1:
The fastening element is designed as a universal component that can be positioned at any location along the frame section, including near corner joints and miters. The same base and mandrel structure provides both the guide engagement for positioning and the pivotal mounting function, eliminating the need for separate corner-specific attachment mechanisms.
Solution Approach 2:
The complex bridge element required in prior art solutions is extracted and replaced by the simplified fastening element with base and mandrel portions. The base portion engages with the guide structure while the mandrel portion provides the pivotal mounting, achieving corner-area attachment without requiring additional bridge elements or complex constructions.
3Adaptability or versatility
If additional elements like bridge elements are added to overcome miter limitations, then corner attachment becomes possible, but the construction becomes more complex
Solution Approach 1:
The functions of the bridge element and the fastening element are merged into a single integrated fastening element with base and mandrel portions. The base portion engages with the guide structure to provide positioning, while the mandrel portion extends through the cover plate to provide pivotal mounting, eliminating the need for separate bridge elements.
Solution Approach 2:
The fastening element serves multiple functions: it engages with the guide structure for positioning, provides pivotal mounting through the mandrel portion, and can be positioned at any location including corner joints and miters. This multi-functionality replaces the need for additional specialized elements like bridge elements.

AI summary
The fitting has a fastening element (21) with a base (23) that completely runs within a guide (19) formed along front side of a frame section (11), where the frame section is made of aluminum or plastic. The guide completely runs through the base, and includes an opening over its entire length, where the opening accommodates a bolt (25). The guide protrudes outward from the opening, such that the fastening element is lockable and guidable along the front side of the frame section up to a miter joint (17) that is arranged at an end.
