Pulsed Signal Triggering by Real-Time Moving Element Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling the movement of a moving element relative to a fixed support or object to perform precise treatment operations, such as laser cuts or image capture, are difficult and expensive to implement due to the complexity of calculations and control required for accurate positioning.
Innovation Solution
A method and device that generate a pulsed signal at triggering positions by measuring actual positions in real time, comparing them to desired positions, and emitting a signal when the closest actual position is reached within a given limit, allowing for precise and facilitated implementation of treatment actions across multiple degrees of freedom.

Engineering Contradiction Analysis
1Manufacturing precision
If a master/slave control architecture is used to control treatment operations at specific positions, then treatment actions can be performed at predetermined positions, but the system becomes difficult to implement, expensive, and imprecise due to complex calculations and control requirements
Solution Approach 1:
Instead of controlling the moving element to reach predetermined positions (master control), the patent inverts the approach by having the moving element autonomously determine when it has reached triggering positions based on its own measured position (slave control). This inversion eliminates the complex master/slave control architecture while achieving the same positioning objective.
Solution Approach 2:
The moving element performs self-positioning by autonomously measuring its own position, comparing it to triggering positions, and determining when to execute treatment actions without external control intervention. This self-service approach simplifies the control system while maintaining positioning precision.
2Measurement precision
If real-time position measurement and continuous comparison are implemented to achieve precise triggering, then positioning accuracy is improved, but measurement and detection difficulty increases
Solution Approach 1:
The moving element integrates multiple functions including position measurement, position comparison, and treatment triggering within a single autonomous system. This multi-functionality reduces the need for separate detection and control systems, thereby simplifying the overall measurement and detection architecture while maintaining high positioning accuracy.
