Pipe Binding Assembly With Friction Retention and Alignment Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe binding mechanisms are complex, costly, and limited in stiffness and alignment, leading to potential detachment and reduced binding force due to horizontal and rotational forces on pipes.
Innovation Solution
A pipe binding mechanism using a rubber band with inclined pressure pins and a metallic tightening plate, eliminating interlocking means and allowing for thicker pressure pins, ensuring stable binding without requiring precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If retaining holes and retaining pieces are provided to prevent pipe binding bands from separating, then reliability is improved, but device complexity increases
Solution Approach 1:
The pipe binding bands are merged with the tightening plate through direct contact and frictional engagement, eliminating the need for separate retaining holes and retaining pieces. The binding bands wrap around the tightening plate and maintain position through the binding force itself, integrating the retention function into the primary binding structure.
Solution Approach 2:
The retaining holes and retaining pieces are extracted (removed) from the design. The invention deliberately omits these additional components, relying instead on the inherent mechanical engagement between the pipe binding bands and tightening plate through friction and geometric constraint.
2Ease of manufacture
If pressure pins are made thinner to maintain flexibility of band body, then ease of manufacture is improved, but strength decreases
Solution Approach 1:
The pressure pins are designed with non-uniform cross-sectional properties along their length. The pins have a thicker section at the mounting end for strength and stiffness, transitioning to a thinner section at the tip for flexibility and ease of insertion. This local variation in quality allows the pin to satisfy both manufacturing ease and structural strength requirements.
Solution Approach 2:
The pressure pins are made from composite materials or material combinations that provide both strength and flexibility. The pin structure may incorporate different materials or material treatments in different regions to achieve the desired balance between stiffness for load-bearing and flexibility for installation and band conformity.
3Force
If pressure pins are aligned in circumferential direction, then binding force effectiveness is improved, but ease of operation decreases
Solution Approach 1:
The invention transitions from requiring precise two-dimensional circumferential alignment to a more tolerant three-dimensional arrangement. The pressure pins are positioned at multiple locations around the tightening plate, and their effectiveness is maintained through the cumulative binding force in multiple directions rather than relying on precise alignment of individual pins in a single circumferential plane.
Solution Approach 2:
The pressure pins are designed to be positionally versatile, where their exact circumferential alignment is not critical. The pins can be positioned at various locations around the tightening plate and still provide effective binding force, making the system universally applicable without requiring precise alignment during installation.

AI summary
A pipe binding mechanism, which connects a first pipe and a second pipe, both made of a synthetic resin material, may include: a rubber band which is formed in a ring shape penetrated longitudinally and is made of a flexible material capable of being in close contact with the outer surfaces of the first and second pipes; a tightening plate which is made of an elastic metallic material, formed to wrap connected ends of the first and second pipes in the circumferential direction, and configured for both ends to overlap each other and to wrap the rubber band from the outside; and a pair of pipe binding bands which are respectively arranged at both widthwise ends of the tightening plate and configured to adjust the close contact force relative to the outer surfaces of the first and second pipes.
