Hidden Hinge Load-Bearing Accessory for Tilt-Turn Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load-bearing hinges for doors and windows, particularly hidden hinges, have limited load-bearing capacity and are costly, and cannot be applied to tilt and turn windows due to their inherent structure.
Innovation Solution
A load-bearing accessory with an adjustable and resilient connector that supports the hinge, allowing it to be applied to both casement and tilt and turn windows, featuring an adjustable distance between support components and a flexible connector to distribute load effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid shaft is used to connect frame body and sash member, then load-bearing capacity is improved, but the accessory becomes longer and more expensive
Solution Approach 1:
The patent divides the load-bearing function into two separate components: a hidden hinge for rotation and a load-bearing accessory for supporting weight. This segmentation allows each component to be optimized independently - the hinge remains compact while the load-bearing function is distributed through additional support elements attached to the frame
Solution Approach 2:
The patent introduces an intermediary load-bearing accessory that connects the frame to the sash member alongside the hidden hinge. This intermediary component shares the load-bearing responsibility, allowing the hidden hinge to remain short and simple while the overall system achieves high load-bearing capacity through the combined action of hinge and accessory
2Device complexity
If hidden hinges are used, then structure is concealed and aesthetics are improved, but load-bearing capacity is limited
Solution Approach 1:
The patent separates the rotational function (handled by the concealed hidden hinge) from the load-bearing function (handled by additional support accessories). This allows the aesthetic benefit of hidden hinges to be preserved while the load-bearing limitation is overcome by adding dedicated support elements that work in conjunction with the hinge
Solution Approach 2:
The patent combines the hidden hinge structure with additional load-bearing accessories attached to the frame. These accessories merge with the frame structure to provide supplementary support, allowing the system to achieve both concealment (through the hidden hinge) and high load-bearing capacity (through the combined hinge-accessory system)
3Strength
If open hinges are used, then load-bearing capacity is improved, but the hinge structure is visible and aesthetics deteriorate
Solution Approach 1:
The patent divides the visible open hinge into separate functional elements: the hidden hinge (concealed for aesthetics) and the load-bearing accessory (attached to the frame). This segmentation allows the rotational function to be concealed while the load-bearing function is handled by accessories that can be integrated into the frame structure, achieving both aesthetic and structural goals
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The accessory enhances load-bearing capacity while reducing costs and extends the service life of hidden hinges by distributing load efficiently, enabling application to various window types including tilt and turn windows.
Implementation Method 1
A load-bearing accessory uses a rigid shaft to connect a frame body and a sash member. The resilient connector supports the hinge, allowing it to be applied to both casement and tilt and turn windows

AI summary
Provided are a load-bearing accessory and a window. The load-bearing accessory includes a hinge, a frame and a connector. The frame includes an adjustment portion and a support portion. The distance between the adjustment portion and the support portion is adjustable. A first end of the connector is connected to the hinge, and a second end of the connector is connected to the adjustment portion. One of the hinge or the frame that is located at the upper position of the load-bearing accessory is configured to support the connector, and the connector is configured to support the other one of the hinge or the frame that is located at the lower position of the load-bearing accessory.
