Micro Trenching Machine With Adjustable Saw Blade Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid increase in friction between the saw blade and the trench sides due to uneven ground surfaces leads to premature wear and destruction of the saw blade, as engines with high power are used for micro trenching, causing the saw blade to overheat before mechanical wear occurs.
Innovation Solution
A machine with a stabilizing device and individually vertically adjustable wheels to maintain a constant saw blade angle and height, reducing friction and extending the lifespan of the saw blade, while also allowing for precise placement of ducts/cables and filling material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the saw blade is used for sawing micro trenches on uneven ground surfaces, then the sawing operation can be performed, but the friction between the saw blade and trench sides increases rapidly causing the saw blade to overheat and be destroyed before mechanical wear occurs
Solution Approach 1:
The patent applies dynamics by making the saw blade angle adjustable during operation. The saw blade angle adjustment device allows the operator to change the saw blade angle relative to the direction of motion based on ground unevenness, enabling the system to adapt dynamically to varying conditions and maintain optimal cutting performance while reducing friction and heat generation that lead to blade destruction
Solution Approach 2:
The patent changes the parameter of saw blade angle to resolve the contradiction. By allowing adjustment of the saw blade angle between 0-45 degrees relative to the direction of motion, the system can optimize cutting conditions for different ground surfaces, reducing excessive friction and heat that cause premature blade failure while maintaining productivity
2Adaptability or versatility
If the saw blade angle changes due to uneven ground surfaces, then the sawing machine can adapt to terrain variations, but the friction between the saw blade and trench sides increases causing rapid temperature increase and blade destruction
Solution Approach 1:
The patent uses dynamics by implementing a movable saw blade angle adjustment mechanism that allows real-time modification of the saw blade orientation. This dynamic adjustment capability enables the system to adapt to terrain variations while maintaining optimal cutting angles, preventing excessive friction and heat generation that would otherwise destroy the blade
Solution Approach 2:
The patent incorporates feedback through the operator's ability to observe ground conditions and adjust the saw blade angle accordingly. The system responds to terrain feedback by allowing angle modifications, enabling adaptation to uneven surfaces while controlling harmful friction and heat effects through informed operational adjustments
3Productivity
If high power engines (100 horsepower or more) are used to drive the saw blade for efficient sawing, then the sawing speed and productivity are improved, but the friction-generated heat causes the saw blade to overheat and be destroyed rapidly
Solution Approach 1:
The patent changes the operational parameter of saw blade angle to optimize the balance between cutting efficiency and heat generation. By adjusting the angle between 0-45 degrees, the system can maintain effective cutting with high power engines while reducing excessive friction that causes rapid temperature increase and blade destruction
