Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-propelled vehicles and modular systems for oversize loads face challenges in distributing weight evenly, maintaining stability, and maneuverability, particularly when transporting heavy loads with limited ground contact points and high resting surfaces.
Innovation Solution
A self-propelled module with oil-pressure controlled ground movement assemblies and suspension systems, featuring tracked shoes with independent oscillation and a low resting surface, combined with a modular design allowing adaptation to various transport requirements, enables efficient weight distribution and improved steering capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wheeled transport is used, then the device can move efficiently, but the number of ground resting points is reduced, causing poor weight distribution
Solution Approach 1:
The vehicle body is divided into multiple independent modules, each equipped with its own propulsion system and ground contact points. This segmentation allows the vehicle to maintain efficient movement while increasing the number of distributed ground resting points through multiple modules working in parallel.
2Weight of moving object
If the resting surface is raised to accommodate heavy loads, then the load capacity increases, but the stability and balance of the load deteriorates
Solution Approach 1:
The vehicle transitions from a single elevated resting surface to multiple low-level ground contact points distributed across several modules. This dimensional redistribution of support points maintains load capacity while improving stability by lowering the center of gravity and distributing weight across a wider base.
3Quantity of substance
If modular tracked systems are used, then ground contact is improved, but any minimal hollow causes height differences between modules, creating stresses and imbalances
Solution Approach 1:
Each module is equipped with independent oil-pressure controlled suspension systems that dynamically adjust to terrain variations. This allows each module to maintain optimal ground contact while compensating for height differences caused by minimal hollows, preventing stresses and imbalances between modules.
Solution Approach 2:
Hydraulic suspension systems are implemented in each module to provide active height control and level maintenance. The hydraulic mechanisms absorb terrain irregularities and maintain consistent module positioning, eliminating the stability problems caused by ground hollows.
4Ease of operation
If conventional steering mechanisms are used, then the vehicle can change direction, but the steering angle is limited and maneuverability in confined spaces is poor
Solution Approach 1:
The steering system is segmented across multiple independent modules, each capable of independent rotation and orientation. This allows the vehicle to achieve complex maneuvers and larger effective steering angles by coordinating the movement of individual modules, greatly improving adaptability in confined spaces.
