Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipeline inspection robots require multiple driving units for each proceeding wheel, increasing their size and making it difficult to navigate the complex and 3-dimensional shapes of pipelines, especially in hard-to-reach areas.
Innovation Solution
A robot equipped with a multi-output differential module that distributes driving power to multiple proceeding units from a single driving unit, reducing the need for individual driving units and allowing the robot to navigate complex pipeline structures efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple driving units are installed for each proceeding wheel to control motion individually, then the control precision and motion control capability are improved, but the device size and structural complexity increase
Solution Approach 1:
The patent combines multiple driving units into a single integrated driving unit that simultaneously controls multiple proceeding wheels. The driving unit includes a motor, transmission mechanism, and differential mechanism that work together as one unified system to distribute power to multiple wheels, reducing overall device complexity while maintaining individual wheel control capability
Solution Approach 2:
The single driving unit is designed with multi-functional capability to control multiple proceeding wheels through a differential mechanism. This universal driving unit can adapt to different pipeline configurations and control multiple wheels simultaneously, eliminating the need for separate dedicated driving units for each wheel
2Reliability
If multiple individual driving units are installed for each proceeding unit, then the reliability of each proceeding unit is improved, but the overall system complexity and size increase
Solution Approach 1:
The patent merges multiple individual driving units into one integrated driving assembly that serves multiple proceeding wheels. This unified driving system maintains reliability by providing coordinated control through the differential mechanism, which ensures each wheel receives appropriate power while reducing the total number of independent driving components in the system
