Track Support Guidance for Free-Moving Carriages in Curved Passages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatment systems with free-moving transport trolleys face challenges in navigating curved sections and maintaining orientation, leading to potential collisions and inefficiencies due to inadequate sensor arrangements, which result in production stoppages and increased wear on components.
Innovation Solution
A mechanical and/or sensor-dependent track support device is introduced to actively or passively coordinate the main orientation and conveying direction of the transport trolleys, using near-field sensors and mechanical guide structures to maintain a predetermined tolerance distance from the connecting passage edges, allowing for smoother navigation through curved routes and reduced collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If free-moving transport trolleys navigate curved sections without track support, then the system maintains flexibility and avoids infrastructure installation, but collisions occur between the connecting device and connecting passage edges
Solution Approach 1:
A mechanical track support device is introduced as an intermediary between the transport trolley and the connecting passage. This device includes support elements that extend from the floor into the travel space, providing physical guidance and preventing the transport trolley from deviating into the connecting passage during curved navigation, thereby eliminating collisions while preserving system flexibility
Solution Approach 2:
The patent replaces sensor-dependent active coordination systems with a passive mechanical guidance system. The track support device uses fixed mechanical structures (support elements and guiding surfaces) to automatically guide the transport trolley through curved sections, eliminating the need for complex sensors and control algorithms while ensuring reliable collision-free operation
2Difficulty of detecting and measuring
If far-field sensor arrays are used for obstacle detection, then navigation capability is improved, but false obstacle detection occurs in confined travel spaces
Solution Approach 1:
The patent extracts and removes the problematic far-field sensor arrays from the transport trolley system. By eliminating these sensors that cause false detections in confined spaces, the system avoids the reliability issues associated with false obstacle detection while maintaining navigation capability through passive mechanical guidance
Solution Approach 2:
The mechanical track support device provides self-service guidance by using fixed physical structures to automatically guide the transport trolley through the travel space and curved sections. The system serves itself through passive mechanical interaction between the support elements and the trolley, eliminating the need for active sensor-based detection and control
3Manufacturing precision
If active sensor-dependent coordination is implemented, then orientation precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex active sensor-dependent coordination systems with simple passive mechanical guidance structures. The track support device uses fixed support elements and guiding surfaces to automatically maintain the transport trolley's orientation and position, achieving reliable navigation without sensors, control units, or complex electronics
Solution Approach 2:
The mechanical track support device uses simple, inexpensive components such as support elements, guiding surfaces, and mechanical structures that can be easily manufactured and installed. These simple mechanical elements provide reliable guidance at a fraction of the cost of sensor arrays and active control systems
