Solution Overview
Problem
Existing processing machines with two clamping areas along the pivot axis require complex operation and can lead to inaccuracies due to the need for separate tensioning and the risk of incomplete clamping, reducing ease of use and working accuracy.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two independent clamping areas are provided along the pivot axis, then the stability of the machine is improved, but the operating effort and complexity increase due to separate tensioning of each clamping area
Solution Approach 1:
The patent combines two independent clamping areas into a single integrated clamping device with a common actuating mechanism. The actuating device simultaneously tensions both clamping areas through a shared transmission system, merging what were previously separate operations into one unified action. This reduces operating effort while maintaining the stability benefits of dual clamping points.
Solution Approach 2:
The actuating device is designed with multi-functionality to simultaneously control both clamping areas. A single actuating mechanism performs the function of what would otherwise require two separate actuators, allowing the user to tension and release both clamping areas with one operation. This universal actuating system maintains simplicity while achieving the stability of dual clamping zones.
2Stability of the object's composition
If two independent clamping areas are used, then the stability is improved, but the adjustment accuracy deteriorates due to potential misalignment when clamping at different pivoting positions
Solution Approach 1:
By merging the control of both clamping areas into a single actuating device with synchronized transmission, the patent ensures that both clamping points are engaged at the exact same pivoting position. This eliminates the accuracy problems associated with independent clamping areas, as the unified mechanism guarantees simultaneous engagement and maintains precise angular alignment throughout the adjustment range.
Solution Approach 2:
The integrated transmission system provides inherent feedback synchronization between the two clamping areas. As the actuating device operates, the transmission mechanism ensures both clamping points respond simultaneously and equally, providing automatic feedback that prevents misalignment. This ensures that clamping forces are applied at identical pivoting positions, maintaining high adjustment accuracy.
3Device complexity
If separate clamping areas are operated independently, then the device complexity remains manageable, but the reliability deteriorates due to the risk of incomplete clamping on one side
Solution Approach 1:
The patent merges the actuation control of both clamping areas into a single integrated system. This ensures that when the user operates the clamping device, both clamping areas are engaged simultaneously and equally, eliminating the reliability risk of forgetting to clamp one side. The unified mechanism makes incomplete clamping impossible while keeping the overall device complexity manageable through shared components.
Solution Approach 2:
The integrated clamping device with common actuation provides a self-service mechanism that automatically ensures both clamping areas are properly engaged. The synchronized transmission system self-regulates to apply equal clamping forces at both points, eliminating human error and the need for separate verification steps. This self-correcting mechanism significantly improves reliability without adding complex control systems.

AI summary
The machine has an operation unit (13) pivotable relative to a base unit (11). A clamping unit is provided for fixing the operation unit to the base unit for continuous adjustment of a pivoting angle. The operation unit and the base unit are prestressed with each other at clamping regions (15, 17). The clamping regions are placed at a distance along a pivoting axis (19). The clamping unit has a common actuating unit (21) for the clamping regions. The actuating unit produces a clamping force (26) in the clamping regions for pretensioning the base unit and operation unit.
