Solution Overview

Problem

Conventional apparatuses for dumping aggregate on railroad tracks lack precision and safety, as they are not equipped to deliver aggregate accurately and simultaneously to all track areas, and manual methods expose operators to safety risks due to the need for close proximity and real-time adjustments.

Innovation Solution

A dumping system with a dump box and multiple delivery gates, operated by a hydraulic system controlled by a wireless controller, allowing for real-time adjustment of aggregate delivery to all areas of the track without requiring the operator to be in close proximity to the aggregate, and enabling portability to different track locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual dumping gates are used, then accurate dumping of ballast to the track is achieved, but precise dumping is not possible and safety risks increase due to operator proximity to falling aggregate

Engineering Contradiction:
Improvedumping accuracyVSAvoidsafety risks to operator
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

A hydraulic actuation system serves as an intermediary between the operator and the dumping gate. The operator controls a remote control unit that activates hydraulic cylinders to move the gate, eliminating the need for the operator to be in close proximity to falling aggregate while maintaining precise control over the dumping process

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The manual mechanical operation of the dumping gate is replaced with an automated hydraulic system. The hydraulic cylinders, actuated by a remote control unit, provide precise and controlled movement of the gate, substituting manual mechanical adjustment with an automated system that improves both precision and safety

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the gate position is modified by an individual being positioned on the hi-rail equipment as it moves, then real-time adjustment of the gate is possible, but the individual is subject to increased safety risk associated with being unrestrained on a moving vehicle and being in close proximity to falling aggregate

Engineering Contradiction:
Improvereal-time adjustment capabilityVSAvoidsafety risks on moving vehicle
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The remote control unit acts as an intermediary that allows the operator to adjust the gate position from a safe distance. The operator can be positioned on the ground or in a secure area while controlling the hydraulic system remotely, eliminating the need to be unrestrained on the moving vehicle

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Manual mechanical adjustment of the gate by an operator on the vehicle is replaced with an automated hydraulic actuation system controlled remotely. This substitution enables real-time adjustment without requiring the operator to be physically present on the moving equipment

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If the gate position is modified by halting the hi-rail equipment, then safety risks associated with falling aggregate remain reduced, but real-time adjustment of the gate is not possible and aggregate delivery precision is compromised

Engineering Contradiction:
Improvesafety risks reducedVSAvoidaggregate delivery precision
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

Manual adjustment requiring vehicle halting is replaced with an automated hydraulic system that can adjust the gate position in real-time while the vehicle is in motion. The hydraulic cylinders respond instantly to remote control signals, maintaining precision without requiring the vehicle to stop

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system transitions from a static adjustment method (requiring vehicle halt) to a dynamic adjustment method. The hydraulic actuation system allows continuous real-time adjustment of the gate position while the vehicle moves, enabling precise aggregate delivery without interrupting the transport process

Inventive Principle:
Principle #15Dynamics

4Quantity of substance

If ballast cars are used, then delivery of aggregate to one track area is achieved, but precision is lacking and the system cannot deliver aggregate to all track areas simultaneously

Engineering Contradiction:
Improveaggregate delivery capabilityVSAvoiddumping precision
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The dumping system is segmented into multiple independent delivery gates (first delivery gate, second delivery gate, third delivery gate) that can be controlled separately. Each gate can be adjusted independently to deliver aggregate to specific track areas with precision, and all gates can operate simultaneously to serve multiple areas

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system achieves multi-functionality by enabling the same platform to deliver aggregate to multiple different track areas (left side, between rails, right side) simultaneously. The multiple delivery gates with independent hydraulic control allow the system to adapt to different delivery requirements at different locations

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A dumping system for accurate and precise dumping of ballast rock, sand, and gravel (aggregate) to all areas of a railroad track (a track) is described. The dumping system includes a dump box, a dump gate having at least two delivery gates, an operating system, and a control system. The at least two delivery gates of the dump gate each include a top portion and a bottom portion. The bottom portion of each of the at least two delivery gates is adjusted in real time by the operating system via the control system to accurately and precisely deliver the aggregate to all areas of the track. The dump box may further be rotated horizontally and vertically to aid with the delivery of aggregate to the track in an accurate manner.
