Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coiled tubing transportation systems face challenges with increased tubing footage needs, leading to strained transportation methods due to heavy equipment and weight restrictions, which limit maneuverability and increase the risk of equipment damage and operational inefficiencies.
Innovation Solution
An improved steering and suspension system for coiled tubing equipment, incorporating a booster assembly with a pivoting payload portion and auxiliary dolly, which adjusts weight distribution and steering capabilities to enhance maneuverability and safety during transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If trailer lengths are extended to transport more tubing footage, then the transportation capacity is improved, but the turning capability and maneuverability deteriorate due to limited turning radius and steering restrictions
Solution Approach 1:
The trailer is divided into multiple independent sections with individual steering axles. Each section can be steered independently, allowing the long trailer to navigate tight turns by coordinating the movement of different segments, thus resolving the contradiction between increased length and reduced maneuverability
Solution Approach 2:
The steering system is made dynamic by allowing different axles to be steered at different angles and times during the turning process. The system can adjust steering angles in real-time based on the turning radius requirements, enabling the long trailer to achieve tight turning capability while maintaining its extended length for transporting more tubing
2Weight of moving object
If additional axles are added to reduce weight per axle ratio, then the weight distribution is improved, but the turning capability and steering flexibility deteriorate
Solution Approach 1:
The trailer with multiple axles is segmented into steerable sections, where each axle or group of axles can be independently controlled. This segmentation allows the system to distribute weight across multiple axles while maintaining steering flexibility by activating only the necessary steerable axles during turning maneuvers
Solution Approach 2:
The steering system is designed to serve multiple functions: it can steer the entire trailer for general directional changes, steer individual axles for tight turning maneuvers, and distribute weight across multiple axles for stable transportation. This multi-functionality resolves the contradiction between weight distribution and turning capability
3Quantity of substance
If heavy equipment is transported to meet increased tubing footage requirements, then the transportation capacity is improved, but the risk of equipment damage and operational inefficiencies increases due to weight restrictions and maneuverability limitations
Solution Approach 1:
The heavy equipment and long trailer are segmented into manageable sections with independent steering control. This segmentation reduces stress concentration on any single component during turning maneuvers, lowering the risk of equipment damage while maintaining the capacity to transport increased tubing footage
Solution Approach 2:
The dynamic steering system adjusts axle angles and forces in real-time during operations, optimizing the distribution of mechanical loads on the equipment. This dynamic load management prevents excessive stress on critical components, enhancing equipment reliability while transporting heavy loads over long distances

AI summary
An auxiliary dolly is attachable to the rear of a primary trailer. The auxiliary dolly includes a first portion attachable to the primary trailer; a second portion comprising a chassis with one or more axles with wheels and a payload portion on the chassis. The payload portion is configured to pivot relative to the chassis with one or more axles with wheels of the second portion. A pivot point is at the point where the first portion is coupled to and movable relative to the second portion. Two or more cylinders are configured to pivot the payload portion of the second portion relative to the chassis with one or more axles with wheels of the second portion he pivot allows the payload portion to be substantially aligned with the primary trailer while turning.
