Window And Door Electrical Linkage With Enclosed Pivot Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical assemblies for windows and doors that connect a moveable window sash or door panel to a frame require substantial modifications, are difficult to conceal, and limit the opening positions, necessitating improvements for efficient power transfer and concealment.
Innovation Solution
An electrical linkage assembly with pivotably coupled link arms and enclosed electrical wires that extend from a frame mount to a sash mount, allowing for a compact design that protects and supports electrical wiring during pivoting and translating movements of the window or door panel, without compromising the hinge's load-bearing characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing electrical assemblies are used to connect the window sash to the frame, then electrical power can be transferred, but the assembly requires substantial modifications to the window structure and is difficult to conceal
Solution Approach 1:
The electrical wires are nested within the hollow cylindrical link arms, which are themselves part of the hinge assembly. This nesting allows the electrical components to be integrated within the existing mechanical structure without requiring separate conduits or substantial modifications to the window frame or sash.
Solution Approach 2:
The link arms serve multiple functions: they provide the mechanical pivot connection for the hinge while simultaneously serving as protective conduits for the electrical wires. This multi-functionality eliminates the need for separate electrical routing paths and reduces overall assembly complexity.
2Reliability
If existing electrical assemblies are used to connect the window sash to the frame, then electrical power can be transferred, but the assembly limits the opening positions of the window sash
Solution Approach 1:
The electrical linkage assembly is designed to be dynamic rather than rigid. The link arms can pivot and adjust their positions as the window sash moves through its full range of motion, allowing the electrical connection to maintain integrity while accommodating all opening positions without restriction.
Solution Approach 2:
The assembly allows for parameter changes in the position and orientation of the link arms as the window opens. The electrical wires within the hollow link arms can accommodate the changing geometric parameters of the hinge mechanism throughout the full range of motion.
3Reliability
If electrical wires are routed through the hinge assembly, then power can be transferred to the moving sash, but the wires are exposed to wear, moisture, and kinking
Solution Approach 1:
The electrical wires are nested within the hollow cylindrical link arms, which provide physical protection. This nesting shields the wires from external harmful factors including wear from friction, moisture from the environment, and kinking from bending stresses during hinge movement.
Solution Approach 2:
The hollow cylindrical link arms act as flexible protective shells that enclose the electrical wires. These shells allow the wires to move with the hinge while maintaining protection, preventing direct exposure to moisture and mechanical damage.

AI summary
An electrical linkage assembly for a window or door includes a frame mount, a sash mount, a first link arm, and a second link arm. A first pivot joint is formed between the frame mount and the first link arm, a second pivot joint is formed between the first and second link arms, and a third pivot joint is formed between the second link arm and the sash mount. One or more electrical wires extend from the frame mount, through the first and second link arms and each of the first, second, third pivot joints, fully enclosed therein, and out of the sash mount.
