Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Twisted sealing rings for sewer pipes, often resulting from manufacturing, require manual rotation to achieve a stable circumferentially uniform position, which is costly and inefficient.
Innovation Solution
A method and device utilizing a motor-driven torsion bar to set partially twisted rings in centrifugal rotation, with a stop edge for impact assistance, allowing them to 'spring back' into a stable position, enabling automated processing of multiple rings simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual rotation is used to return twisted rings to stable position, then alignment accuracy is improved, but labor cost and processing time increase
Solution Approach 1:
The twisted rings automatically return to their stable circumferentially uniform position through self-service mechanisms: the centrifugal rotation creates stretching forces that activate the rings' elastic memory, and the stop edge provides impact assistance to accelerate the return to stable position, eliminating the need for manual intervention
Solution Approach 2:
The system applies mechanical vibration through centrifugal rotation at 500-1500 RPM, which stretches the twisted rings and activates their elastic recovery mechanism, causing them to spring back to their stable position rapidly and efficiently
2Manufacturing precision
If manual intervention is used to correct twisted rings, then processing quality is improved, but operational complexity increases
Solution Approach 1:
The device eliminates manual intervention by implementing self-service operation: twisted rings are automatically subjected to centrifugal rotation and impact forces that return them to stable position, achieving high alignment quality through automated physical mechanisms rather than human operation
Solution Approach 2:
The system transitions from static manual adjustment to dynamic automated processing, where the rotary drive creates controlled dynamic conditions (centrifugal force, stretching, impact) that automatically guide the rings to their stable position, improving both ease of operation and processing quality
3Ease of operation
If rings are processed one at a time, then handling simplicity is improved, but productivity decreases
Solution Approach 1:
The system processes multiple rings simultaneously by segmenting them along the torsion bar, with each ring independently subjected to the centrifugal rotation and return-to-stable mechanism, maintaining handling simplicity while achieving batch processing of up to 50 rings at once
Solution Approach 2:
The device merges multiple individual ring processing operations into a single unified operation: all rings on the torsion bar are simultaneously subjected to centrifugal rotation and automatic return to stable position, dramatically increasing throughput while maintaining operational simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method efficiently returns twisted rings to their stable position within a short time, eliminating the need for manual intervention and integrating seamlessly into production processes, with the potential for simultaneous processing of up to 50 rings at 500-1500 RPM, achieving 100% alignment in 10-30 seconds.
Implementation Method 1
the partially twisted rings are set in a centrifugal rotation by means of a rotary drive arranged eccentrically to the ring axis until they have reached a stable, circumferentially uniform basic position
Implementation Method 2
This stretching causes the rings to 'spring back' into their stable, circumferentially uniform position
Implementation Method 3
the rings hit against a stop edge during the slinging, which can for example be designed as a rod or wall, so that the impact effect on the rings supports the reverse rotation

AI summary
Back rotation of partially twisted flexible rubber or synthetic plastic rings, especially sealing rings for waste water pipes, in a stable equidirectional base position, so that the rings (1,7,9,10) are maintained in centrifigal rotation by a rotation drive (2,4) excentric to the ring axis until the rings attain their stable uniform base position. An independent claim is included for a device for back rotation of partially twisted flexible rubber or synthetic plastic rings.
