Eccentric Tensioning Ring for Profile Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tensioning systems require substantial mechanical adaptations and numerous components, making them difficult to mount, adjust, and fix, especially in situ.
Innovation Solution
A simplified tensioning system utilizing a single tensioning ring with a rotationally secure bolt that removes play between profiles by rotation, serving multiple functions including tensioning and fixing without additional parts or holes, allowing for rapid mounting, adjustment, and re-adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional tensioning systems with multiple adapter rings and bolts are used, then the profiles can be connected, but the system requires substantial mechanical adaptations and numerous components making mounting and adjustment difficult
Solution Approach 1:
The patent merges multiple separate components (adapter rings and bolts) into a single integrated tensioning ring with an eccentric bore. This single component performs the functions of both the adapter ring and the bolt, eliminating the need for separate fastening elements and reducing the total number of parts required for assembly.
Solution Approach 2:
The tensioning ring with eccentric bore serves multiple functions simultaneously: it acts as an adapter ring to connect profiles with overlapping holes, provides an integrated fastening mechanism through the eccentric bore, and enables tensioning through rotational movement. This multi-functionality eliminates the need for separate specialized components.
2Reliability
If multiple adapter rings and bolts are used to connect profiles, then secure connection is achieved, but greater skill is required during mounting and adjusting
Solution Approach 1:
By combining the adapter ring and bolt functions into a single integrated tensioning ring with eccentric bore, the system reduces the complexity of assembly operations. The integrated design eliminates the need for separate alignment and fastening steps, reducing the skill level required for proper installation while maintaining connection security.
3Reliability
If a bolt with bolt head is used, then fixing is achieved, but additional parts and holes are required
Solution Approach 1:
The tensioning ring integrates the fastening function directly into its structure through the eccentric bore, eliminating the need for separate bolts with heads. The bore itself serves as the fastening element, and the rotational mechanism provides both tensioning and fixation functions within the same component.
Solution Approach 2:
The eccentric bore serves multiple purposes: it provides the fastening mechanism, enables rotational tensioning, and eliminates the need for separate bolt holes in the profiles. This multi-functionality reduces the total number of holes and parts required in the overall assembly.

AI summary
Profiles 2-1, 2-2 which are clamped on top of one to another and which are each provided with overlapping holes 3-1, 3-2, and a tensioning ring 4 which comprises a cylindrical portion 4-1 the outer circumference of which contacts, in the hole 3-1, the first profile 2-1, and which comprises a portion 4-2 having an enlarged outer circumference. An eccentric axial bore 5 extends through both tensioning ring portions, into which bore a bolt 6 can be inserted which also passes through the hole 3-2 in the second profile, the head 7 or nut of said bolt being recessed in the bore in a rotationally secure manner.
