Cylinder Cover with Integrated Sensor and Floating Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cylinder arrangements in pneumatic or hydraulic systems face challenges in assembly due to manufacturing tolerances, requiring complex and time-consuming processes to ensure proper sealing and sensor integration.
Innovation Solution
A cover for cylinder arrangements is designed with an integrated sensor unit, featuring a coil that generates sensor signals by induction, and a fastening device to simplify assembly by compensating for manufacturing tolerances and providing a floating mount, allowing for easy alignment and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the sensor unit is integrated into the cover, then the assembly process is simplified and production time is reduced, but the manufacturing precision requirements increase due to tolerance compensation needs
Solution Approach 1:
The cover is designed with a floating mount capability that allows dynamic adjustment of the sensor unit position relative to the cylinder. This dynamic positioning compensates for manufacturing tolerances in both the cylinder and cover, enabling easy assembly without requiring high precision while maintaining proper sensor alignment through the flexible mounting interface
Solution Approach 2:
The receptacle geometry is specifically designed to accommodate position variations within tolerance ranges. By changing the geometric parameters of the receptacle (size, shape, positioning features), the system can absorb manufacturing variations and still achieve proper sensor unit integration without requiring tight tolerance control
2Reliability
If the coil is arranged around a receptacle with fastening device, then the sensor unit can be securely mounted, but the cover structure becomes more complex
Solution Approach 1:
The receptacle and fastening device are merged into a single integrated feature of the cover. Instead of being separate components, the receptacle incorporates the fastening functionality directly, simplifying the overall cover structure while ensuring reliable sensor unit mounting through the combined geometric design
