Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting sleeves for corrugated pipes are complex and costly to manufacture, making them inefficient for quick and reliable connections.
Innovation Solution
A connecting sleeve divided into two identical half-sleeves with engagement elements that engage with corrugated pipe troughs, secured by snap-fit connections, allowing easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex one-piece or multi-part coupling sleeves are used to connect corrugated pipes, then connection reliability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The coupling sleeve is divided into two separate semi-cylindrical half-shells that can be assembled around the corrugated pipes. This segmentation allows the coupling sleeve to be opened and closed like a clamp, enabling easy installation without requiring the pipes to be threaded through, while maintaining secure connection through the interlocking half-shells with engagement elements that grip the pipe corrugations
2Reliability
If complex one-piece or multi-part coupling sleeves are used to connect corrugated pipes, then connection reliability is improved, but manufacturing cost increases
Solution Approach 1:
The coupling sleeve is divided into two separate semi-cylindrical half-shells that can be assembled around the corrugated pipes. This segmentation allows the coupling sleeve to be opened and closed like a clamp, enabling easy installation without requiring the pipes to be threaded through, while maintaining secure connection through the interlocking half-shells with engagement elements that grip the pipe corrugations
3Stability of the object's composition
If traditional coupling sleeves are used to connect corrugated pipes, then connection stability is improved, but installation time increases
Solution Approach 1:
The coupling sleeve is divided into two separate semi-cylindrical half-shells that can be assembled around the corrugated pipes. This segmentation allows the coupling sleeve to be opened and closed like a clamp, enabling easy installation without requiring the pipes to be threaded through, while maintaining secure connection through the interlocking half-shells with engagement elements that grip the pipe corrugations
Solution Approach 2:
The engagement elements are designed as separate integral hinges that protrude from the half-shells, allowing them to be independently positioned and engaged with the pipe corrugations. This extraction of the engagement function into separate elements allows for quick adjustment and secure gripping without complex assembly procedures

AI summary
For connecting two corrugated pipes, the invention proposes a tubular connecting sleeve (1) with two identical, interlocking, semi-cylindrical shell-shaped half-sleeves (2) which have circumferential, semicircular ribs (6, 6') for engaging in the troughs of the corrugation of the corrugated pipes on their inner sides.
