Goods Transport Facility Rail Width Adjuster Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing goods transport facility generates noise due to the collision of side rollers with rails in curved parts of the transportation path, limiting the flexibility of the layout and requiring extensive modifications to reduce noise.
Innovation Solution
Incorporating a rail width adjuster that reduces the gap between the side rollers and rails in transition regions and areas where the direction of the curve changes, preventing strong impacts and noise by maintaining continuous contact between the rollers and rails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the side roller is provided to limit lateral movement of the transport carriage, then the transport carriage is prevented from separating from the transportation path, but noise is generated due to strong collision with the rail in curved parts
Solution Approach 1:
The side roller is designed to be movable in the lateral direction rather than fixed, allowing it to dynamically adjust its position. This enables the side roller to maintain contact with the rail during curved movement without generating strong collision impacts, thus reducing noise while preserving lateral movement limitation functionality
Solution Approach 2:
The lateral position of the side roller is changed according to the curvature of the transportation path. By adjusting the lateral position parameter of the side roller based on whether the path is straight or curved, the system maintains reliable lateral limitation while avoiding strong collisions and noise generation in curved sections
2Object-generated harmful factors
If the transition region from linear part to curved part is extended to reduce noise, then the side roller collision impact is reduced, but the flexibility of transportation path layout is limited
Solution Approach 1:
Instead of extending the transition region, the side roller's lateral position is made dynamic to adapt to different path configurations. This allows noise reduction through controlled lateral movement adjustment rather than through geometric path design constraints, preserving layout flexibility
Solution Approach 2:
The lateral position parameter of the side roller is adjusted according to the path curvature rather than changing the physical dimensions of the transition region. This parameter-based solution reduces noise without imposing geometric constraints that would limit layout flexibility
