Solution Overview

Problem

Conventional anti-skid devices for tracked vehicles fail to provide adequate traction, especially on sloping roads with ice or snow, and often require significant space for fasteners, which can lead to contact or damage to the chassis.

Innovation Solution

An anti-skid device with a base body having floor sections and a rib section that is curved and divided into rib parts, featuring traction elements and fastening points for anchoring on a caterpillar belt, designed to improve traction by enhancing lateral force absorption and reduce slipping, while allowing for a space-saving and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If conventional anti-skid devices are used, then traction is improved, but lateral slipping is not sufficiently prevented

Engineering Contradiction:
ImprovetractionVSAvoidlateral slipping prevention
Core Design Contradiction:
ForceVSReliability

Solution Approach 1:

The base body is segmented into multiple bottom sections and rib sections arranged in succession along the direction of travel. This segmentation allows the device to distribute lateral forces across multiple contact points with the track, significantly improving lateral slipping prevention while maintaining traction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention adds a vertical dimension to lateral force absorption by creating rib sections that extend upward from the bottom sections. This three-dimensional structure provides both lateral support and vertical engagement with the track, simultaneously improving traction and preventing lateral slipping.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Force

If conventional anti-skid devices are used, then traction is improved, but space for fastening elements is required

Engineering Contradiction:
ImprovetractionVSAvoidfastening space
Core Design Contradiction:
ForceVSArea of stationary object

Solution Approach 1:

The fastening elements are integrated directly into the base body structure, merging the attachment function with the structural components. This eliminates the need for separate fastening spaces and reduces the overall footprint of the device on the track.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base body serves multiple functions: it provides structural support, creates traction surfaces, and incorporates fastening elements. This multi-functionality reduces the need for additional components and spaces dedicated solely to fastening.

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

3Force

If conventional anti-skid devices are used, then traction is improved, but contact or damage to chassis may occur

Engineering Contradiction:
ImprovetractionVSAvoidchassis contact or damage
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

The device is designed with localized engagement features that concentrate traction forces at specific contact points with the track, rather than distributing forces across the entire chassis. This localized approach prevents harmful contact with the chassis while maintaining effective traction.

Inventive Principle:
Principle #3Local quality

AI summary

A skid protection device (E1) for mounting on a track of a tracked vehicle or wheel of a wheel drive comprises a base body (G1) which, along a direction (x) corresponding to the direction of travel of the track or wheel, has at least two base sections (B1, B2) which, in the mounted state, rest on a running surface of the track or wheel, and at least one rib section (R12) that arches upwards above them and is arranged between each pair of base sections. One or more fastening points (B0), into which fasteners can be detachably inserted, are preferably provided in the base sections for anchoring the skid protection device to the track.The rib section (R12) rests on the bottom sections and is divided in the direction (y) transverse to the direction of travel by at least one window (R0) into two or more rib parts (R1, R2); additionally, recesses (A1, A2) may be provided in the side flanks of the rib section. One or more protruding traction elements (T1) may be provided on the outer surfaces (F1, F2) of the rib parts, for example, welded on.
