Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forming devices face challenges in reliably deactivating radiation detectors based on position-dependent signals, which can lead to inaccurate deactivation and potential safety hazards.
Innovation Solution
The safety controller compares first and second status signals, derived from machine and safety control systems respectively, to determine if the radiation detector should be deactivated at a predetermined position, ensuring accurate and safe deactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single position measuring system is used for deactivation control, then the device complexity is reduced, but the deactivation reliability deteriorates due to potential errors in position determination
Solution Approach 1:
The patent implements feedback by comparing the first position value from the machine control with the second position value from the safety control. This comparison mechanism provides feedback verification to ensure accurate position determination before deactivation, thereby improving reliability without significantly increasing complexity
Solution Approach 2:
The patent introduces an intermediary comparison mechanism between the machine control position value and the safety control position value. This intermediary step acts as a mediator to verify position accuracy before triggering deactivation, resolving the contradiction between reliability and complexity
2Manufacturing precision
If position values are corrected using correction values, then the deactivation precision is improved, but the calculation complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing position correction values that compensate for systematic errors in the position measuring system. These correction values are applied in advance to position readings, improving deactivation precision without requiring complex real-time calculations
Solution Approach 2:
The patent changes the position parameter by applying correction values to adjust the raw position measurements. This parameter transformation corrects systematic errors and improves deactivation precision while maintaining relatively simple calculation requirements

AI summary
The invention relates to a forming device (1) with a machine bed (2) on which a first tool (6) is arranged, and with a tool carrier (4) which is relatively movable on the machine bed (2), to which a second tool (5) and a drive device (37) for moving the tool carrier (4) are assigned, with a machine control (11) for controlling the drive device (37) and with a safety control (10) for locking the drive device (37).According to the invention, the safety controller (10) is configured to perform a comparison of a first status signal (a), which results from a comparison between a first actual position value obtained by adding a first position correction value to a first position value with a first deactivation position value, and a second status signal (b), which results from a comparison between a second actual position value obtained by adding a second position correction value to a second position value with the first deactivation position value, for the purpose of deactivating a first radiation detector (23), and to carry out the deactivation if the first status signal (a) and the second status signal (b) match.
