Adjustable Load-Bearing Accessory for Hidden Window Hinges
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 structural design.
Innovation Solution
A load-bearing accessory with an adjustable distance between an adjustment portion and a support portion, featuring a connector that supports the hinge, and a flexible member to distribute load, allowing application to both casement and tilt and turn windows.
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 long and expensive
Solution Approach 1:
The rigid shaft is divided into two parts: a fixed shaft portion connected to the frame body, and an adjustable shaft portion connected to the sash member. This segmentation allows the adjustable portion to be shortened or removed depending on the window type, reducing overall length and cost while maintaining load-bearing capacity when needed
Solution Approach 2:
The shaft structure is made dynamically adjustable through a locking mechanism that allows the shaft length to be modified. The adjustable shaft portion can be extended for casement windows requiring high load-bearing capacity, or retracted/removed for tilt and turn windows where it is not needed, optimizing both performance and cost
2Shape
If hidden hinges are used, then aesthetic appearance is improved, but load-bearing capacity is limited
Solution Approach 1:
The invention merges the functions of a hidden hinge with a load-bearing accessory into a single integrated structure. The hinge is combined with an adjustable shaft and locking mechanism, creating a unified component that provides both the aesthetic hidden hinge appearance and the load-bearing capacity of a separate support accessory
Solution Approach 2:
The load-bearing accessory is designed with multi-functionality to serve both as a hidden hinge for aesthetic purposes and as a load-bearing support structure. The adjustable shaft and locking mechanism enable it to perform multiple functions: providing rotational movement like a hinge while simultaneously supporting heavy sash weights
3Strength
If open hinge structure is used, then load-bearing capacity is improved, but the structure becomes visible and less aesthetic
Solution Approach 1:
The invention merges the functions of a hidden hinge with a load-bearing accessory into a single integrated structure. The hinge is combined with an adjustable shaft and locking mechanism, creating a unified component that provides both the aesthetic hidden hinge appearance and the load-bearing capacity of a separate support accessory
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 provides enhanced load-bearing capacity at a lower cost, supports heavy window sashes, and extends the service life of hidden hinges by distributing load effectively across adjustable components.
Implementation Method 1
a spring, located inside the large diameter segment, has a first end abutting onto a solid end surface of the small diameter segment in a peripheral direction of the small diameter segment and is sleeved outside the connector, and an end portion of the connector abuts onto a second end of the spring

AI summary
A 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.
