Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for transmitting electrical energy and signals through a hinged connection between a wall and a wing suffer from high power loss and difficulty in assembly, particularly when no hinge pin is present, leading to wear and damage from spring forces.
Innovation Solution
A device with a displacement drive that allows the wall and wing transmitter parts to be actuated and positioned precisely, preventing uncontrolled shifting and wear, using an adjusting spindle with a double-acting thread and a locking mechanism for controlled assembly and operation, and incorporating means to prevent rotation and protect cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If spring assemblies are used to press the wall and wing transmitter parts against each other to increase transmissible power, then power loss during transmission is reduced, but the device becomes significantly more difficult to install and wear occurs on the sliding surfaces
Solution Approach 1:
The transmitter parts are pre-assembled in a test position where their end faces are in direct contact, allowing optimization of the magnetic coupling before final installation. This preliminary positioning ensures maximum power transfer efficiency is achieved before the hinge is fully assembled, resolving the contradiction by preparing the optimal configuration in advance rather than relying on spring force during operation.
2Loss of energy
If spring assemblies are used to press the wall and wing transmitter parts against each other, then power loss during transmission is reduced, but wear occurs on the sliding surfaces during opening and closing
Solution Approach 1:
The invention allows the transmitter parts to be displaceable relative to each other in the direction of the hinge axis, enabling dynamic adjustment of their positions. This displacement capability allows the end faces to be brought into direct contact for optimal power transfer while preventing continuous sliding contact that would cause wear, as the parts can be positioned and locked in place rather than constantly sliding against each other under spring force.
3Loss of energy
If the transmitter parts are kept in direct contact to minimize power loss, then transmission efficiency is improved, but the device complexity increases due to the need for displacement control mechanisms
Solution Approach 1:
The invention extracts the displacement control function from complex spring assemblies and separates it into a simple test position for assembly. The transmitter parts are designed to be displaceable along the hinge axis, allowing them to be positioned in a test position during assembly where their end faces contact for optimization, then locked in place. This removes the need for continuous spring force mechanisms, reducing device complexity while maintaining transmission efficiency.
