Solution Overview

Problem

The development of full range track systems has lagged behind non-full range track systems, leading to inefficiencies and increased space requirements, particularly in applications requiring precise positioning and adaptability in small spaces.

Innovation Solution

An omniwheel track system comprising a frame with an endless drive mechanism and segment assemblies, each with load wheels mounted at an angle, allowing omnidirectional movement and load distribution through horizontal and vertical idling wheels supported by the frame, reducing the system's height and enhancing load capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If non-full range track systems are used, then the system structure is simpler and easier to manufacture, but the system requires increased space and lacks adaptability in confined areas

Engineering Contradiction:
Improvesystem structure simplicityVSAvoidadaptability in confined spaces
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The track system is divided into multiple segment assemblies (first, second, third, and fourth segment assemblies) that can independently articulate and rotate. Each segment contains load wheels that can be positioned at different angles, allowing the system to adapt to confined spaces while maintaining structural simplicity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The segment assemblies are designed with dynamic characteristics, allowing them to rotate and articulate relative to each other. The load wheels within each segment can be positioned at different angles (e.g., 45 degrees) and the segments can rotate about vertical axes, enabling the system to dynamically adapt to various spatial constraints and movement requirements

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If full range track systems are developed, then the system offers precise positioning and high adaptability, but the development has lagged and the system complexity increases

Engineering Contradiction:
Improveprecise positioning capabilityVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system is segmented into modular assemblies with standardized interfaces. Each segment assembly contains load wheels, idling wheels, and drive mechanism components that can be independently manufactured and assembled, reducing overall system complexity while enabling precise positioning through coordinated segment movement

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The segment assemblies are designed with universal characteristics, where each segment can perform multiple functions (supporting load, providing articulation, enabling rotation). The load wheels can be positioned at different angles and the segments can rotate about vertical axes, allowing a single modular design to handle various positioning and movement requirements

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

3Length of stationary object

If the endless track system height is reduced, then the system fits better in confined spaces, but the load capacity may be compromised

Engineering Contradiction:
Improvetrack system heightVSAvoidload capacity
Core Design Contradiction:
Length of stationary objectVSForce

Solution Approach 1:

The load distribution is shifted from a vertical configuration to a more distributed three-dimensional arrangement. Load wheels are positioned at different heights and angles within each segment assembly, with some wheels contacting the ground and others providing structural support. This dimensional redistribution allows reduced overall height while maintaining load capacity through spatial optimization

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