Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track maintenance machines are difficult to handle in confined spaces such as switches and bridges due to their fixed dimensions and limited maneuverability, making them inefficient and cumbersome to operate.
Innovation Solution
A track maintenance machine with a connecting unit that allows for adjustable longitudinal and transverse dimensions, enabling flexible orientation and positioning of structural units, along with handles for manual guidance, and a motor-driven mechanism for tool-free displacement, ensuring operation in various orientations and confined areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the track maintenance machine has a fixed large longitudinal dimension for operating comfort with vertical orientation, then the operating comfort is improved, but the machine cannot be used in confined areas such as switches or on bridges
Solution Approach 1:
The connecting unit enables dynamic reconfiguration of the structural units, allowing the machine to transition between a first configuration with a first longitudinal dimension for comfortable operation and a second configuration with a second longitudinal dimension for confined space operation. This dynamic adaptability resolves the contradiction between fixed operating comfort and adaptability to different work environments.
Solution Approach 2:
The machine is divided into at least two reconfigurable structural units connected by a connecting unit. This segmentation allows the structural units to be rearranged between different configurations, enabling the machine to adapt its longitudinal dimension according to the available working space while maintaining operational comfort when space permits.
2Device complexity
If the track maintenance machine is designed with fixed dimensions for structural simplicity, then the device complexity is reduced, but the machine lacks flexibility to adapt to different machining spaces
Solution Approach 1:
The connecting unit provides a relatively simple dynamic mechanism that enables reconfiguration between different longitudinal dimensions. This dynamic element adds minimal structural complexity while maximizing adaptability, allowing the machine to adjust to different machining spaces without requiring completely different machine designs.
3Ease of manufacture
If the motor is integrated into the first structural unit to reduce wear and improve efficiency, then the manufacturing cost and operational wear are reduced, but the machine's ability to adapt to different orientations may be limited
Solution Approach 1:
The motor is integrated into the first structural unit, which can be repositioned relative to the second structural unit through the connecting unit. This segmentation allows the motorized component to remain fixed in one unit while the overall machine configuration adapts to different orientations and working positions, maintaining both manufacturing economy and orientation adaptability.
