Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized apparatus struggle to access and maintain pipes due to inhospitable conditions such as high temperatures, pressures, and obstacles within the interior cavity, making routine inspection and repair challenging.
Innovation Solution
A motorized apparatus with a body assembly, leg assemblies, and drive mechanisms, including mecanum wheels and omni-wheels, that allows for multi-directional movement and rotation within the pipe, enabling it to traverse obstacles and maintain pipes with high degrees of freedom, coupled with a maintenance device for inspection and repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional maintenance apparatus are used in pipes, then the apparatus can perform basic maintenance functions, but the apparatus cannot access pipes with high temperatures, pressures, or obstacles
Solution Approach 1:
The apparatus employs dynamic leg assemblies that can extend and retract to adapt to varying pipe diameters and obstacles. The legs are actuated to maintain contact with the pipe wall, enabling the apparatus to navigate through pipes with different conditions including high temperatures, pressures, and obstacles while maintaining operational capability.
2Ease of operation
If the apparatus structure is simplified for easy operation, then the apparatus can be easily deployed, but it loses the capability to move in multiple directions and rotate
Solution Approach 1:
The drive system is segmented into multiple independent wheel assemblies, each capable of rotation and driven by separate motors. This segmentation allows the apparatus to achieve complex movements (multi-directional travel and rotation) through coordinated control of simple, modular wheel units, maintaining ease of deployment while enabling sophisticated maneuverability.
3Adaptability or versatility
If the apparatus includes multiple drive mechanisms for multi-directional movement, then the apparatus can navigate obstacles and move freely, but the device complexity increases
Solution Approach 1:
The wheel assemblies serve multiple functions: they provide propulsion, enable steering, and allow rotation of the apparatus. Each wheel assembly is a universal component that contributes to various movement modes (forward, backward, lateral movement, and rotation), reducing the need for separate specialized mechanisms and thereby managing complexity while maintaining versatility.
4Reliability
If the apparatus is designed to withstand harsh conditions, then the apparatus can operate in high temperature and pressure environments, but the apparatus becomes more complex and harder to maintain
Solution Approach 1:
The materials and structural parameters of the apparatus are selected and designed to withstand specific harsh conditions (high temperatures, pressures). The leg assemblies and wheel assemblies are constructed with materials and designs that can endure these conditions while maintaining functionality, allowing the apparatus to operate reliably in challenging pipe environments.
