Grease Nipple Encoder Holder for Reliable Lubrication Point Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lubrication connection devices face challenges in providing a reliable and practical solution for identifying lubrication nozzles, especially in harsh environments, while maintaining flexibility and ease of use, due to issues with encoder installation, performance reduction, and compatibility with various configurations and environments.
Innovation Solution
A lubrication connection device featuring a lubricating nozzle with a fixing portion, a lubricating inlet interface, and a flange with a radio frequency encoder holder that allows for axial alignment and torque transmission, ensuring reliable connection and identification, even if the grease supply source is not aligned with the nozzle axis, using a radio frequency encoder with an antenna positioned around the lubrication axis for improved reading capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an encoder and matching element are installed for identification, then identification capability is improved, but device complexity increases
Solution Approach 1:
The encoder holder integrates multiple functions: it holds the radio frequency encoder, provides a bearing surface for the collar, and creates an imprint for housing the collar. This merging of functions into a single component reduces overall device complexity while maintaining identification capability.
Solution Approach 2:
The encoder holder serves multiple purposes: supporting the encoder for identification, providing mechanical alignment through the bearing surface, and enabling torque transmission through the imprint engagement. This multi-functionality eliminates the need for separate components.
2Loss of information
If a radio frequency encoder is used for identification, then identification capability is improved, but connection performance deteriorates
Solution Approach 1:
The encoder is separated from the connection interface by placing it in the encoder holder at a distance from the grease fitting connection point. This segmentation allows the identification system to operate independently without interfering with the mechanical connection performance.
3Loss of information
If an encoder holder is added for encoder mounting, then identification capability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The encoder holder is designed as a single integrated component that combines the encoder mounting structure, the bearing surface for collar support, and the imprint for collar housing. This integration simplifies manufacturing by reducing the number of separate parts that need to be produced and assembled.
