Hinge Slip Ring Integration via Roller Free Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges for doors, windows, and furniture that transmit power or data signals suffer from wear and tear due to recurring movement, leading to potential cable breakage, and require expensive special components and modifications.
Innovation Solution
A hinge design with a free space between rollers to accommodate a standard slip ring, allowing for power and/or signal transmission using standard components, with additional rollers and a hollow pin extension for centering and protection, and groove-shaped cable feedthrough areas for routing cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable is run from the fixed frame across the hinge to the moving element, then power or data signals can be transmitted, but the cable is subject to wear and material fatigue due to repetitive movement
Solution Approach 1:
The patent replaces the mechanical cable transmission system with a wireless communication system. The fixed frame and moving element are equipped with wireless communication modules that transmit power and data signals wirelessly, eliminating the physical cable that was subject to wear and fatigue from repetitive hinge movement.
2Reliability
If a slip ring system is used for wireless energy and signal transmission, then contactless transmission is achieved, but the hinge becomes complex requiring special slip ring system and modifications
Solution Approach 1:
The patent replaces the complex mechanical slip ring system with a wireless communication system using electromagnetic fields. This substitution eliminates the need for special slip rings, grommets, and scanning systems with release springs, thereby simplifying the hinge structure while maintaining contactless transmission capability.
Solution Approach 2:
The patent employs standard wireless communication modules that can be integrated into conventional hinge designs without requiring specialized modifications. These universal components handle both power transmission and data communication functions, reducing the need for separate specialized systems.
3Ease of manufacture
If standard components are used for hinge leaves, then manufacturing cost is reduced, but a gap must be created between rollers to accommodate the slip ring
Solution Approach 1:
The patent replaces the need for modified rollers with gap spaces with a wireless communication system that uses standard solid rollers. The wireless modules are integrated into the hinge leaves, allowing standard roller components to be used without structural modifications while achieving contactless transmission.
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
This design enhances the structural simplicity and carrying capacity of the hinge, reduces wear, and allows for reliable power and signal transmission without the need for costly special components, while maintaining alignment and preventing damage to the slip ring.
Implementation Method 1
a slip ring for current and/or signal transmission is accommodated within the third and fourth rollers
Implementation Method 2
the at least one first roller and the second roller are arranged on a common pivot axis and are pivotably connected to each other about the pivot axis

AI summary
A hinge for doors, windows and furniture with a first hinge leaf (2) with at least one first roller (3) and with a second hinge leaf (4) with a second roller (5), wherein the at least one first roller (3) and the second roller (5) are arranged on a common pivot axis (S) and are pivotably connected to each other about the pivot axis (S), should be suitable for power and/or signal transmission in a structurally simple manner.This is achieved by providing a free space between the at least one first roller (3) and the second roller (5) and by providing a third roller (7) connected to the first belt flap (2) in the assembly position and a fourth roller (9) connected to the second belt flap (4) in the assembly position, wherein the third and fourth rollers (7, 9) are arranged side by side in the free space on the pivot axis (S) and are pivotably connected to each other about the pivot axis (S), wherein a slip ring (10) for power and/or signal transmission is accommodated within the third and fourth rollers (7, 9).
