Integrally Formed Bolt-Like Domes for Window Hinge Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillating hinges for windows, particularly roof windows, have complex structures requiring many components and assembly steps, leading to a risk of incorrect assembly and insecure connections.
Innovation Solution
The oscillating hinge features integrally formed bolt-like domes on the intermediate element that engage with the base body and cover element, eliminating the need for separate connecting bolts and simplifying assembly, while reshaping the domes creates secure grips for a stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connecting bolts are used to fasten the intermediate element to the base body and cover element, then secure connections can be achieved, but the number of components increases and assembly complexity increases
Solution Approach 1:
The patent integrates the connecting bolts into the intermediate element by forming bolt-like domes directly on it. This merging of the intermediate element and connecting bolts into a single piece reduces the number of separate components while maintaining secure connections through the dome structures that engage with openings in the base body and cover element.
2Ease of manufacture
If separate connecting bolts are used to fasten the intermediate element to the base body and cover element, then connections can be made, but the risk of incorrect assembly increases
Solution Approach 1:
The patent employs asymmetric design where the bolt-like domes are formed integrally on specific sides of the intermediate element with specific orientations. The domes have grips behind the openings that create a unique engagement geometry, ensuring that components can only be assembled in the correct orientation. This asymmetric configuration prevents incorrect assembly while maintaining ease of manufacture.
3Reliability
If multiple bolt-like connections are formed on the intermediate element, then secure fastening is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent performs preliminary action by forming all bolt-like domes on the intermediate element during its initial manufacturing process before assembly. The domes are pre-formed with their gripping structures in place, so that during final assembly, no additional forming operations are needed. This preliminary formation of connecting elements simplifies the overall manufacturing process while ensuring secure connections.

AI summary
The invention relates to a pivot hinge (3) for a window, in particular a roof window, with a frame bearing (1) that can be fixed to a frame of the window and with a sash bearing (2) that can be fixed to a sash frame of the window, wherein the frame bearing (1) has a base body (4) to which at least one intermediate element (6) and at least one cover element (7) are attached by means of bolt-like connections to form a slide guide (9). It is provided that bolt-like domes (20, 21) are formed integrally on both sides (18, 19) of the intermediate element (6), which engage in openings (16, 17) of the base body (4) and the cover element (7) and fix the base body (4) and the cover element (7) there by forming a recess.
