Solution Overview

Problem

Existing road bed rehabilitation machines lack the ability to adapt their working width to navigate around obstacles and narrow sections of track beds, requiring additional space when not in operation.

Innovation Solution

The machine incorporates lateral position sensors and extensible channels with a transverse face that can modify its working width, adapt to different cross-sectional widths, and be connected or detached efficiently, allowing it to navigate around obstacles and narrow sections without occupying additional space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the working width of the transverse face is fixed, then the machine structure is simple, but the machine cannot adapt to obstacles or narrow sections of track bed

Engineering Contradiction:

Improveadaptability to obstacles and narrow sectionsVSAvoidcomplexity of extensible face structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transverse face is divided into multiple segments that can move independently relative to each other. The face comprises a first portion and a second portion that can be positioned at different distances from the tower, allowing the working width to be adjusted in discrete steps while maintaining structural manageability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transverse face is designed with dynamic positioning capability through telescopic mechanisms. The face can extend and retract along the longitudinal axis of the machine, transforming from a static structure to a dynamically adjustable one that adapts to varying track bed conditions

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the transverse face is always connected to the machine, then the machine is ready for immediate operation, but the face occupies additional space on the cross section when not in use

Engineering Contradiction:

Improvereadiness for immediate operationVSAvoidspace occupied on cross section

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The transverse face is designed to rotate about a vertical axis, allowing it to transition from a lateral position (occupying cross-sectional space) to a longitudinal position (aligned with the machine's length). This dimensional change enables the face to be stowed without occupying valuable lateral space while remaining quickly deployable

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the working width is increased to accommodate all possible track bed conditions, then the machine can handle any cross-section, but the machine becomes wider and requires more space for operation

Engineering Contradiction:

Improvecapability to handle any cross-sectionVSAvoidwidth of the machine

Core Design Contradiction:

Adaptability or versatilityVSArea of moving object

Solution Approach 1:

The machine employs a dynamic working width adjustment system where the transverse face can telescopically extend or retract. This allows the machine to present a narrow profile when navigating tight spaces while being capable of expanding to handle wider track bed sections when needed, eliminating the need for a permanently wide design

Inventive Principle:

Principle #15Dynamics

AI summary

Machine for restoring track beds comprising a die cart (1) which is fitted with at least one pair of lateral channels (10, 10'), along which an excavating chain (6, 7) runs, which is deflected on one side onto corresponding actuating means (5) and on the other side is guided into an excavation end face (12); on the side of each of the channels (10, 10') there is attached at least one positional sensor (15, 15') which can detect the width of the cross-section of the platform (P, Ρ'), in which the machine is working, and/or the possible presence of one or a plurality of obstacles, and the end face (12) and at least one of the channels (10, 10') are telescopically connected; this end face (12) can be displaced with respect to the channel (10, 10') using at least one actuator (13, 13'). These channels (10, 10') are connected to each other by at least one actuator (16) and the excavating chain (6, 7) is deflected around at least one displaceable element (4).
