Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for controlling recurring movement sequences, such as those used in underground settings, often require long paths for controls to ensure accurate positioning over time, which can be inefficient.
Innovation Solution
The proposed solution involves an energy transmission device with a control mechanism that stores potential energy and uses a spindle drive with a threaded spindle and nut to efficiently transport the control to stop positions, allowing for reduced path lengths while maintaining accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If long paths are provided for the control element to ensure accurate positioning over time, then positioning reliability is improved, but device complexity and path length increase
Solution Approach 1:
The control device monitors the actual position of the control element during movement and compares it with the target position. Based on this feedback, the control device adjusts control parameters (such as motor voltage, current, or pulse width) to compensate for deviations caused by positioning shifts, ensuring accurate stopping at the target position without requiring excessively long paths.
Solution Approach 2:
The system dynamically changes control parameters during the movement sequence based on detected position deviations. By adjusting parameters such as motor drive voltage, current intensity, or deceleration timing, the system compensates for positioning drift and ensures the control element reaches the correct stop position even after extended operation periods.
2Measurement precision
If the control element is moved frequently to maintain positioning accuracy, then positioning precision is improved, but energy consumption increases
Solution Approach 1:
The control device uses feedback from position sensors to determine when positioning correction is actually needed. Instead of频繁ly moving the control element, the system only adjusts positioning when deviations are detected, thereby maintaining precision while minimizing unnecessary energy consumption from frequent movements.
Solution Approach 2:
The system applies positioning corrections only when and to the extent necessary to maintain accuracy. Rather than continuously adjusting the control element position, the system performs partial corrections only when positioning drift exceeds acceptable thresholds, optimizing the balance between precision maintenance and energy conservation.
3Manufacturing precision
If deceleration parameters are modified during subsequent driving processes, then positioning accuracy is improved, but control complexity increases
Solution Approach 1:
The control device automatically detects positioning deviations and calculates appropriate deceleration parameter adjustments based on feedback from position sensors. This automated feedback-based adjustment maintains positioning accuracy while minimizing the need for complex manual control interventions.
Solution Approach 2:
The control system automatically adjusts its own deceleration parameters based on detected positioning errors. The system performs self-correction by modifying its control parameters without requiring external intervention, thereby maintaining positioning accuracy while keeping the control interface relatively simple.
