Pivot Joint Fluid Line System for Pipeline Rehabilitation Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipeline rehabilitation apparatuses face limitations in rotating about their longitudinal axis due to rigid pressure lines, restricting the achievable angle of rotation and making it difficult to align components precisely for rehabilitating pipes with branches or inclines.
Innovation Solution
Incorporating a pivot joint into the fluid line system allows for rotation of the apparatus and its components without twisting the fluid lines, enabling alignment and rehabilitation of pipes with branches or inclines by subdividing the fluid line into sections that can rotate independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid pressure lines are used in the rehabilitation apparatus, then structural stability is maintained, but the achievable angle of rotation is limited and torsional stress occurs
Solution Approach 1:
The fluid line system is divided into multiple sections with pivot joints between them. Each section can rotate independently relative to the others, allowing the overall system to achieve greater rotation angles without twisting individual line segments. This segmentation maintains line integrity while enabling adaptability.
Solution Approach 2:
Pivot joints are introduced as intermediary elements between fluid line sections. These pivot joints act as mediators that allow rotational movement while maintaining fluid pressure transmission. The pivot joints absorb the torsional stress that would otherwise be transmitted through the rigid pressure lines.
2Adaptability or versatility
If the apparatus is rotated to align with pipe branches or inclines, then rehabilitation capability is improved, but pre-alignment requirements increase complexity
Solution Approach 1:
The apparatus transitions from a static, pre-aligned configuration to a dynamic system where the fluid line sections can rotate and adapt their orientation during operation. The pivot joints enable the apparatus to dynamically align with pipe branches or inclines without requiring complex pre-alignment mechanisms.
Solution Approach 2:
The pivot joint mechanism serves multiple functions: it maintains fluid pressure transmission, enables rotational movement, and accommodates various pipe geometries (branches, inclines). This multi-functionality reduces the need for separate alignment mechanisms for different pipe configurations.
3Ease of operation
If fluid lines are twisted during rotation, then apparatus positioning is achieved, but torsional stress damages the fluid lines
Solution Approach 1:
By segmenting the fluid line system into rotatable sections connected by pivot joints, the apparatus can be positioned without twisting the fluid lines. Each section rotates independently at the pivot joints, eliminating torsional stress on the line material while achieving the desired apparatus positioning.
