Conveyor Trolley Movable Side Wall Pivot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport trolleys used in agriculture for transporting cargo like hay or straw bales face limitations in driving safety and versatility, particularly due to excessive vibrations affecting the movable side walls during operation.
Innovation Solution
The transport trolley features a movable side wall that pivots upwards, supported by a stop not integral to the front and rear walls, with a kinematic tube and rod system connected via joint plates, and a lattice-like structure for the walls and stops, enhancing stability and reducing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable side wall is lowered next to the transport vehicle to simplify loading, then loading convenience is improved, but driving safety deteriorates due to excessive vibrations
Solution Approach 1:
The side wall is designed to be movable between two positions: lowered next to the vehicle for loading and raised above the vehicle for transport. This dynamic reconfiguration allows the system to optimize for loading convenience during loading operations and for driving safety during transport, resolving the contradiction between these two requirements.
Solution Approach 2:
A guide mechanism consisting of a guide tube and guide rod acts as an intermediary between the side wall and the vehicle body. This intermediary structure controls the movement of the side wall, enabling it to transition smoothly between the lowered loading position and the raised transport position while maintaining structural integrity and reducing vibrations during driving.
2Reliability
If the side wall is raised above the front and rear walls to improve driving safety, then curve negotiation capability is improved, but structural complexity increases
Solution Approach 1:
The side wall transitions from a static structure to a dynamic one that can be raised above the front and rear walls during transport. This dynamic positioning improves curve negotiation capability by allowing the side wall to clear obstacles and follow the vehicle's movement more effectively, while the raised position is only maintained when needed for driving safety.
Solution Approach 2:
The guide mechanism is segmented into a guide tube attached to the vehicle body and a guide rod attached to the side wall, connected through a pivot joint. This segmentation allows each component to perform its specific function independently while working together to enable the side wall to raise and lower smoothly, managing structural complexity through functional decomposition.
3Reliability
If a stop is added between the movable side wall and the front/rear walls to reduce vibrations, then driving safety is improved, but device complexity increases
Solution Approach 1:
The stop function is merged with the guide mechanism. The guide tube and guide rod, which already control side wall movement, also serve as the stop structure when the side wall is in the raised position. This integration eliminates the need for separate stop components, reducing device complexity while maintaining vibration reduction and driving safety improvements.
