Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coiled tubing equipment transportation systems face challenges in optimal weight distribution and adjustment, particularly in heavy load scenarios, where traditional auxiliary dollies fail to effectively compensate for load imbalances and uneven weight distribution.
Innovation Solution
An auxiliary dolly system with a pivot point and adjustable hydraulic, pneumatic, or mechanical components that allows flexible coupling between two portions, enabling dynamic weight redistribution between the primary trailer and the dolly, utilizing sensors and pressurized systems to manage weight transfer and prevent overload, and incorporating a safety mechanism to maintain stability and balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional auxiliary dolly is used to distribute weight, then the number of axles is fixed and structure is simple, but the weight distribution cannot be dynamically adjusted to compensate for load imbalances
Solution Approach 1:
The patent applies the dynamics principle by making the dolly structure adjustable rather than fixed. The first and second portions are connected via a pivot point that allows relative movement, and cylinders (hydraulic, pneumatic, or mechanical) are incorporated to dynamically adjust the angle and position of the first portion relative to the second portion. This enables the weight distribution to be changed based on loading conditions, resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If the auxiliary dolly has fixed portions, then the structure is stable and easy to manufacture, but the weight cannot be reapportioned between trailer and dolly when overload conditions occur
Solution Approach 1:
The patent implements dynamic adjustability through the pivot point connection and cylinder mechanism. The first portion can rotate or pivot relative to the second portion, allowing the system to adapt weight distribution in real-time. This dynamic capability enables weight reapportionment when overload conditions occur, while the overall assembly remains relatively simple through the use of standard pivot and cylinder components.
Solution Approach 2:
The patent changes the geometric parameters of the dolly structure by allowing the first portion to change its angle and position relative to the second portion. The cylinders adjust parameters such as the extension length and pivot angle, which directly control the weight distribution. This parameter variability enables the system to respond to different loading conditions while maintaining a straightforward mechanical design.
3Reliability
If no weight adjustment mechanism is provided, then the device is simple and reliable, but overload conditions cannot be prevented and stability is compromised
Solution Approach 1:
The patent enhances reliability by incorporating a dynamic adjustment mechanism that allows the system to adapt to varying load conditions. The pivot point and cylinder assembly enable real-time weight redistribution, preventing overload conditions that would compromise stability. While this adds some complexity, the mechanism uses standard components and straightforward geometry to maintain relative simplicity.
