Multi-Profile Clamping Retainer for Stable Pole Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping retainers lack versatility in accommodating various pole profiles and profiles with different cross-sections, and they often require additional components like bolts or nuts for assembly, which can complicate the fastening process.
Innovation Solution
A clamping retainer comprising multiple half-shells with varying clamping faces and bores, allowing for the secure fastening of poles and profiles with circular or rectangular cross-sections, using threaded rods and sockets for tool-free assembly, and featuring pressure plates for even pressure distribution and rib-and-notch guidance to prevent tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a clamping retainer uses a single uniform clamping face design, then the structure is simple, but it cannot accommodate various pole profiles and cross-sections
Solution Approach 1:
The clamping retainer is divided into multiple half-shells, each with different clamping face designs (straight, round, oval). This segmentation allows each half-shell to be optimized for specific pole profiles while maintaining overall structural simplicity through modular assembly.
Solution Approach 2:
The clamping retainer achieves multi-functionality by incorporating multiple types of clamping faces (straight for rectangular profiles, round for circular profiles, oval for elliptical profiles) within a single device, enabling it to accommodate various pole profiles and cross-sections without requiring multiple specialized retainers.
2Reliability
If additional components like bolts or nuts are used for assembly, then the fastening is secure, but the assembly process becomes complicated
Solution Approach 1:
The clamping faces are integrated directly into the half-shells, merging the clamping function with the structural component. This eliminates the need for separate clamping elements or additional fastening components, simplifying both the device structure and the assembly process while maintaining secure fastening through the inherent clamping geometry.
3Stability of the object's composition
If pressure is applied unevenly during clamping, then assembly is simple, but the pole becomes unstable and may tilt
Solution Approach 1:
Different clamping faces (straight, round, oval) are designed with specific geometries optimized for their respective pole profiles. This local quality ensures that each clamping face contacts the pole along its entire surface area, distributing pressure evenly and preventing tilting without requiring complex pressure distribution mechanisms.

AI summary
The invention relates to a clamping retainer (1) for fastening a pole, the clamping retainer (1) comprising at least two similarly shaped half shells (2) respectively having a straight side (4) and a clamping side (5) in an axial direction (A), wherein at least four or eight bores (3.1 to 3.8) running in an axial direction (A) are provided, uniformly distributed over a compass of the half shell (2), wherein a respective straight first clamping face (6) having a first width is arranged on two sides of the half shell (2) lying opposite each other in a radial direction, wherein, starting from the straight first clamping face (6), a length of the half shell (2) in the axial direction (A) increases in multiple steps (7) resulting in further straight clamping faces (8, 9, 10) with an increasing width, wherein a respective first round clamping face (11) having a shape comprising a radius or a shape of a parabola or hyperbola around its apex is arranged on two sides of the half shell (2) lying opposite each other in a radial direction and offset by 90° relative to the two sides with the straight clamping faces (6, 8, 9, 10).
