Innovation Solution
A securing system for freight wagons with entrance and non-entrance area floors equipped with rolling mechanisms and position-limiting mechanisms that allow cargo movement and secure positioning in both directions, enabling quick loading, conveying, and securing of cargos, enhancing transport efficiency and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional cargo loading methods are used with workers manually loading and stacking cargos, then the structure is simple, but the loading and securing speed is slow and cannot meet high-speed railway freight requirements
Solution Approach 1:
The securing system employs dynamic position-limiting mechanisms that can switch between blocking and non-blocking states. The position-limiting members are movable and can be adjusted based on whether cargo loading is in progress or complete, enabling quick transition between loading and securing phases without requiring complex fixed structures throughout.
Solution Approach 2:
The floor is divided into entrance area and non-entrance area with different rolling mechanism configurations. The entrance area has rolling mechanisms in both transverse and longitudinal directions for flexible cargo entry, while the non-entrance area has rolling mechanisms only in the longitudinal direction for streamlined cargo movement and positioning.
2Reliability
If cargos are stacked tightly pressed against each other without specialized securing devices, then the device complexity is low, but the cargo security and reliability are insufficient for high-speed transportation
Solution Approach 1:
The rolling mechanisms and position-limiting mechanisms work together to enable cargo to be both moved and secured by the same system infrastructure. The position-limiting members automatically limit cargo position when in the blocking state, providing self-service securing without requiring separate dedicated securing devices for each cargo item.
Solution Approach 2:
The position-limiting mechanisms serve dual functions: they allow cargo to pass during loading (non-position-limiting state) and then limit cargo position to secure it (position-limiting state). This multi-functionality reduces the need for separate loading and securing device systems.
3Productivity
If high-speed railway freight vehicles are developed for large-scale batch cargo transportation, then the transport efficiency and productivity increase, but the requirement for specialized securing systems increases device complexity
Solution Approach 1:
The position-limiting members are extracted as separate movable components from the floor structure, allowing them to be independently controlled and switched between blocking and non-blocking states. This extraction enables the securing function to be activated only when needed, maintaining simple loading procedures while providing robust securing capability.
