Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for centering and locking a rotating tower in operator vehicles are laborious, inefficient, and prone to inaccuracies due to reliance on operator empirical control and manual activation, leading to repeated corrections and potential deviations from the central position under inertial loads.
Innovation Solution
An assisted centering device equipped with a detector and control module that uses sensors to provide progressive proximity signals for precise positioning and automatic locking, allowing for automated control of the tower's rotation and locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the operator manually controls the tower rotation towards the central position using empirical methods and visual signals, then the device complexity is reduced, but the positioning precision and time efficiency deteriorate due to repeated corrections and inability to instantaneously stop at the central position
Solution Approach 1:
The patent replaces the manual mechanical control system with an automated electro-hydraulic control system. A control module receives signals from detectors about the tower's angular position and automatically activates the hydraulic motor to rotate the tower, eliminating the need for manual operator intervention and visual signals while achieving precise positioning at the central position
Solution Approach 2:
The control system performs self-correction by continuously monitoring the tower's position through detectors and automatically adjusting the rotation to maintain precise central positioning. The system serves itself by detecting position deviations and autonomously correcting them without external manual input
2Device complexity
If the operator manually activates the locking device after reaching the central position, then the device complexity is reduced, but the reliability deteriorates due to potential deviations from the central position under inertial loads during vehicle driving
Solution Approach 1:
The control module automatically activates the locking device as soon as the tower reaches the central position, performing the locking action in advance before inertial loads from vehicle acceleration can cause position deviations. This preliminary automated locking prevents potential position drift without requiring manual operator intervention
3Device complexity
If the operator receives visual signals and manually reverses rotation to correct position, then no additional sensors are needed, but the time efficiency and productivity deteriorate due to laborious repeated corrections
Solution Approach 1:
The patent replaces manual reversal operations with automated bidirectional control. The control module receives detector signals and automatically reverses the hydraulic motor's rotation direction to correct position deviations, eliminating the time-consuming manual reversal process and significantly improving centering operation efficiency
