Screw Clamp Rotating Receiving Element for Welding Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screw clamps are limited in flexibility and adjustability, and they often generate undesired torques when fixing workpieces, particularly on welding tables, due to their rigid design and misalignment of longitudinal axes.
Innovation Solution
A carrier element with a circular cross-section and two axes of rotation, allowing for flexible adjustment and alignment with welding tables, which includes a receiving element that can pivot or rotate to accommodate workpieces with curved surfaces, and a holder element with L-shaped legs for enhanced stability and weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid design with fixed longitudinal axes is used in screw clamps, then structural stability is improved, but flexibility and adaptability to various workpiece shapes deteriorate
Solution Approach 1:
The patent introduces a rotatable receiving element that can pivot around its longitudinal axis and rotate around a transverse axis, transforming the rigid fixed-structure into a dynamic adjustable-structure. This allows the screw clamp to adapt to various workpiece shapes and positions while maintaining structural stability through controlled rotational movements.
Solution Approach 2:
The screw clamp is divided into functionally independent segments: a support element with a receiving element that can rotate independently, and a fastening element that can be adjusted separately. This segmentation allows each component to perform its specific function optimally while providing overall flexibility through the combination of movable parts.
2Ease of manufacture
If the longitudinal axes of support elements and fastening elements are misaligned, then ease of assembly is improved, but torque generation that prevents reliable workpiece fixation worsens
Solution Approach 1:
The receiving element acts as an intermediary component between the support element and the fastening element. It provides a rotational joint that accommodates misalignment of longitudinal axes, allowing the fastening element to be assembled easily even when axes are not perfectly aligned, while still preventing unwanted torques from affecting workpiece fixation reliability.
3Manufacturing precision
If a rigid fixed-structure is used in screw clamps, then manufacturing precision is improved, but adjustability to accommodate curved surfaces and various applications deteriorates
Solution Approach 1:
The receiving element is designed with rotational capabilities around two axes, transforming a static precisely-manufactured component into a dynamic adjustable component. This allows the screw clamp to adapt to curved surfaces and various applications while maintaining manufacturing precision through controlled rotational movements rather than requiring complex custom manufacturing for each application.

AI summary
The invention relates to a first carrier element (1) for a screw clamp (2) having a first element (3) which has a substantially circular cross section and two free ends (3a, 3b). Furthermore, it has a holder element (4) which is arranged on one of the two free ends (3a, 3b) of the first element (3), and a substantially annular receiving element (5) which is rotatably arranged on the holder element (4) and which is suitable for receiving a fastening means (6). A longitudinal axis L3 of the first element (3) and a longitudinal axis L5 of the receiving element (5) can intersect at a point of intersection S of which the position is independent of a rotary position of the receiving element (5). The receiving element (5) can be rotatable about an axis of rotation which is perpendicular to the longitudinal axis L3 of the first element (3) and the longitudinal axis L5 of the receiving element (5).
