Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing piston-cylinder units face challenges in production costs, component variety, positioning and alignment of the piston motion sensor, mounting and detaching effort, and variability of usage conditions, particularly when integrating the sensor into different dimensions and applications.
Innovation Solution
The integration of a positioning and alignment element in the transverse bore of the cylinder head ensures precise positioning and alignment of the piston motion sensor, allowing the same sensor to be used across different piston-cylinder units with varying dimensions, and a releasable connection system for the sensor and housing plugs adapts to different applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the piston motion sensor is integrated into the cylinder head with precise positioning and alignment, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
A positioning and alignment element is introduced as an intermediary component between the piston motion sensor and the cylinder head. This element simplifies the integration process by providing a standardized interface that ensures precise positioning and alignment of the sensor without requiring complex custom fabrication or adjustment mechanisms.
Solution Approach 2:
The integration system is divided into separate functional modules: the piston motion sensor, the positioning and alignment element, and the cylinder head. This segmentation allows each component to be manufactured and adjusted independently, reducing overall device complexity while maintaining measurement precision.
2Adaptability or versatility
If different piston-cylinder units are designed for different applications with varying dimensions, then the adaptability is improved, but the manufacturing complexity and component variety increase
Solution Approach 1:
The positioning and alignment element is designed as a universal component that can be applied across different piston-cylinder unit dimensions and applications. This universal interface allows the same piston motion sensor to be adapted to various applications without requiring application-specific sensor designs, thereby reducing component variety while maintaining adaptability.
Solution Approach 2:
Instead of changing the sensor design for different applications, the solution changes the dimensional parameters of the positioning and alignment element to accommodate different cylinder head dimensions. This allows the core sensor component to remain identical across applications while adapting to specific dimensional requirements.
3Reliability
If the piston motion sensor is firmly integrated into the cylinder head, then the measurement reliability is improved, but the ease of repair and maintenance decreases
Solution Approach 1:
The positioning and alignment element provides a dynamic integration solution that allows the piston motion sensor to be firmly secured during operation for reliable measurements, while enabling easy removal and replacement when maintenance or repair is needed. This is achieved through a secure but reversible mounting mechanism.
Solution Approach 2:
The sensor integration system is segmented into removable components, allowing the piston motion sensor to be separated from the cylinder head for maintenance while maintaining a stable connection during operation. This segmentation enables independent replacement of the sensor without affecting the cylinder head or other components.
