Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanisms for transferring signals between rotating and non-rotating structures, such as slip rings, pre-twisted wire bundles, and mercury-filled rotary devices, are limited by size constraints and space requirements, hindering design flexibility and reducing the number of signals that can be transferred effectively, especially in compact systems like spacecraft and aircraft.
Innovation Solution
A conformal slip ring system comprising a first and second plate with circular conductive segments of varying diameters, offset along the axis of rotation, allowing continuous communication during rotation and conforming to curved surfaces, thereby reducing the size and weight of signal transmission components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional slip rings or flexible tape cables are used for signal transmission, then signal transfer between rotating and non-rotating structures is achieved, but the device size and weight increase, limiting design flexibility in compact systems
Solution Approach 1:
The slip ring is segmented into multiple conductive segments arranged in a circular pattern, with each segment independently connected to corresponding segments on the rotating structure. This segmentation allows for a more compact design compared to traditional continuous-ring slip rings, reducing overall device size and weight while maintaining signal transmission capability.
Solution Approach 2:
The invention transitions from a planar arrangement of conductive elements to a three-dimensional circular arrangement with segments positioned at different angular positions. This dimensional change allows multiple signal paths to be packed into a smaller radial space, reducing the overall footprint and weight of the signal transmission device.
2Quantity of substance
If more conductive segments are added to increase signal capacity, then more signals can be transferred, but the device complexity and space requirements increase
Solution Approach 1:
The circular arrangement of conductive segments serves multiple functions simultaneously: it provides mechanical support for the rotating structure, enables signal transmission through the segmented contacts, and allows for angular positioning of the rotating component. This multi-functionality reduces the need for separate structural and electrical components, simplifying the overall device complexity.
3Productivity
If traditional rotary mechanisms are used, then signal transmission is achieved, but the volume and space requirements limit the number of components that can be integrated
Solution Approach 1:
The conductive segments are arranged concentrically in a circular pattern, with inner segments nested within the radial space of outer segments. This nested arrangement allows multiple signal paths to be integrated within a compact radial footprint, significantly reducing the overall volume of the signal transmission device compared to linear or planar arrangements.
