Modular Fixing Element With Rotatable Joints For Compact Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular fixing elements for clamping devices lack flexibility in space utilization, particularly in complex three-dimensional applications, as they are limited to a single installation direction and rotation about the longitudinal axis, making it difficult to achieve precise positioning and compact design.
Innovation Solution
A modular fixing element with at least two rotatable parts, one carrying the pressure piece and the other the counter-bearing, allowing adjustable rotation angles beyond 180°, combined with height adjustability and a star-shaped inner contour for secure engagement, enabling flexible installation and precise positioning in complex structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed modular fixing element is used with a single installation direction, then the device structure is simple, but the flexibility in space utilization and installation orientation is limited
Solution Approach 1:
The fixing element incorporates a rotatable connection between the first and second modular pieces, allowing the assembly to dynamically adjust its orientation. The second modular piece can be rotated by at least 180° relative to the first piece around an axis running through both pieces, enabling flexible installation in various orientations while maintaining a compact structure.
2Measurement precision
If the fixing element is designed for precise positioning in complex three-dimensional space, then the positioning accuracy is improved, but the device size increases and compactness is reduced
Solution Approach 1:
The rotatable connection enables the fixing element to achieve precise positioning in complex three-dimensional space by allowing at least 180° rotation of the second modular piece relative to the first. This dynamic adjustment capability provides flexibility in orienting the pressure piece and counter-bearing toward the workpiece without requiring additional space or increasing device volume.
3Productivity
If automated fixing techniques are used instead of manual operation, then the productivity is improved, but the device complexity and space requirements increase
Solution Approach 1:
The fixing element maintains manual operation simplicity while improving productivity through optimized mechanical parameters. The rotatable modular design allows quick repositioning and adjustment without requiring complex automated systems, thereby maintaining ease of operation while achieving efficient fixing operations.

AI summary
The element has a pressing piece (15) arranged at a lever arm (14) that is rotatably supported in a lever arm bearing (17). A counter bearing (4) is positioned opposite to the pressing piece in a holding position. Components e.g. counter bearing piece (2), clamp (6), bridge part (8) and lever part (12) are detachably connected with one another, where the lever part bears the bearing (17) and the piece (2) bears the bearing (4). The lever part and the piece (2) are rotatable with the bearings (4, 17) around a rotation axis and are adjustably fixed to one another in a rotation angle.
