Solution Overview
Problem
Pneumatic systems in trailer vehicles require actuators that can be locked in position to automate the reset process, as manual operation is cumbersome and prone to errors, especially when adjusting the trailer height.
Innovation Solution
A pneumatic control unit with a magnetic locking mechanism that locks the actuator in a specific position and a reset mechanism to automatically return it to a predetermined state, utilizing a magnetic locking force and pneumatic confirmation pressure to ensure safe and accurate operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual actuators are used for raising and lowering the trailer, then the operator can control the position, but the operator must continuously hold the actuator in position and manual resetting is required
Solution Approach 1:
The pneumatic control unit automatically resets the actuator to its initial position after the pneumatic pressure is released, eliminating the need for manual resetting operations. The system serves itself by using the pneumatic pressure cycle to automatically return the actuator to its starting position.
Solution Approach 2:
The manual mechanical operation is replaced by a pneumatic system that automatically positions and resets the actuator. The pneumatic pressure drives the actuator to move along the travel path, substituting manual mechanical control with automated pneumatic actuation.
2Reliability
If the actuator can be locked in position, then the position is stable and automated operation is enabled, but the locking mechanism increases device complexity
Solution Approach 1:
A pneumatic locking mechanism is used where pneumatic pressure engages a locking element to secure the actuator at specific positions along its travel path. The pneumatic system provides both the actuation force and the locking function, integrating multiple functions into a unified pneumatic control system.
Solution Approach 2:
The pneumatic control unit performs multiple functions: it actuates the actuator along the travel path, locks the actuator at desired positions, and automatically resets the actuator to its initial position. This multi-functional design reduces the need for separate mechanisms for each function.
3Reliability
If magnetic locking force is applied to lock the actuator, then the locking is reliable and automatic, but additional magnetic components increase device complexity
Solution Approach 1:
Traditional mechanical locking components are replaced with a magnetic locking mechanism. The magnetic field provides the locking force without requiring complex mechanical interlocking parts, reducing mechanical complexity while maintaining reliable locking functionality.
