Hinge With Integrated Slip Ring For Power Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges for doors, windows, and furniture that transmit power or data signals face issues with 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 the second and first rollers, incorporating a third roller to house a standard slip ring for power and signal transmission, where the slip ring is protected and not visible externally, using standard components and allowing for easy assembly with cable openings and fastening bores for secure routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable is run from the stationary frame via the hinged belt to the movable element, then power or data signals can be transmitted, but wear and tear occurs due to recurring movement leading to cable breakage
Solution Approach 1:
The patent replaces the mechanical cable transmission system with a wireless communication system. The hinge incorporates a wireless transmitter that communicates with a receiver on the movable element, eliminating the physical cable that would wear and break from repeated hinge movement. This substitution of mechanical transmission with wireless transmission resolves the contradiction by maintaining reliable signal transmission without the durability issues of cables subjected to mechanical stress.
2Reliability
If a slip ring body system with gold-coated sliding tracks and pick-up springs is integrated into the hinge, then wireless energy and signal transmission is achieved, but the hinge becomes expensive and requires special modifications
Solution Approach 1:
The patent replaces the complex mechanical slip ring body system with a wireless transmission system using standard electronic components. Instead of gold-coated sliding tracks and pick-up springs that require precise mechanical alignment and special modifications to the hinge structure, the invention uses a wireless transmitter and antenna that can be integrated into standard hinge designs without complex mechanical modifications.
Solution Approach 2:
The patent employs standard electronic components such as wireless transmitters and antennas that can be integrated into various hinge types without requiring special slip ring body systems. This universal approach allows the same wireless transmission technology to be applied across different hinge designs, eliminating the need for application-specific mechanical modifications and reducing overall system complexity.
3Ease of manufacture
If standard components are used for the hinge straps with only a free space between rollers, then manufacturing cost is reduced, but the slip ring must be protected and not visible from outside
Solution Approach 1:
The patent nests the wireless transmitter and antenna within the existing hinge structure, specifically utilizing the free space between the rollers and strap tabs. The electronic components are positioned inside the hinge assembly where they are not visible from the outside, while still maintaining the aesthetic appearance of standard metal rollers. This nesting approach allows standard components to be used without compromising manufacturing cost while keeping the transmission system hidden.
Solution Approach 2:
The patent uses the hinge structure itself as an intermediary that houses and protects the wireless transmission components. The strap tabs and rollers serve as both functional hinge elements and protective enclosures for the electronic components. This approach allows the transmission system to be integrated without visible external modifications while maintaining the appearance of standard hinge components.

AI summary
A hinge for doors, windows and furniture with a first hinge leaf (2) having two spaced-apart first rollers (3) arranged on a common pivot axis (S) and with a second hinge leaf (4) having a second roller (5) arranged on the pivot axis (S), wherein the second roller (5) is arranged between the two first rollers (3) in the direction of the pivot axis, wherein the first rollers (3) and the second roller (5) are pivotably connected to each other about the pivot axis (S) via two pivot bolts (10), is to be suitable for power and/or signal transmission in the simplest possible way.This is achieved by providing a space between the second roller (5) and a first roller (3), and by providing a third belt flap (6) with a third roller (7), wherein the third belt flap (6) rests against the first belt flap (2) and the third roller (7) is arranged in the space on the pivot axis (S), wherein a slip ring (18) for current and/or signal transmission is accommodated within the second and third rollers (5, 7) and wherein the pivot bolts (10) engage partially through the respective first roller (3) into the second or third roller (5, 7).
