Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipeline inspection systems (PIS) face challenges due to the large size and limited battery life, which restrict their ability to traverse long pipelines effectively, as they require extensive battery housing and are limited by the battery's charge capacity.
Innovation Solution
The implementation of an induction generator powered by the kinetic energy of the moving PIS within the pipeline, using a magnetic field to generate eddy currents in the conductive pipeline, thereby charging the batteries and reducing the need for large battery housings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If large battery capacity is used to power the PIS for long pipeline traversal, then the operational duration is extended, but the size and diameter of the PIS increase
Solution Approach 1:
The patent combines the battery housing with the PIS inspection apparatus into a single integrated unit, eliminating the need for separate battery compartments. This merging allows the batteries to be compactly arranged within the PIS structure, extending operational duration without increasing overall PIS diameter
Solution Approach 2:
The patent changes the physical arrangement and configuration parameters of the battery housing and battery cells, optimizing their layout to maximize energy density while minimizing volume occupation within the PIS structure
2Volume of moving object
If battery charge capacity is limited, then the PIS size can be reduced, but the range of pipelines that can be inspected is limited
Solution Approach 1:
The patent employs retractable guiding flaps that can dynamically extend and retract based on pipeline conditions. This dynamic mechanism allows the PIS to maintain a compact size for navigation while extending functionality when needed, enabling longer inspection ranges without permanent size increase
Solution Approach 2:
The PIS is divided into functional segments including sensor units, guiding flaps, and power system components. This segmentation allows optimized placement of battery housing and other components to minimize overall volume while maintaining full inspection capability across extended ranges
3Duration of action of moving object
If extensive battery housing is used to accommodate large batteries, then the operational range is extended, but the device complexity increases
Solution Approach 1:
The battery housing is designed to serve multiple functions: it provides structural support for the PIS, contains and protects the battery cells, and integrates with the guiding flap mechanism. This multi-functionality extends operational range while avoiding additional complexity from separate dedicated components
