Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side stabilizers for agricultural machines face challenges such as complex manufacturing requirements, lack of flexibility in adapting to different work conditions, and issues with sealing and durability due to exposure to external agents, as well as complex anti-rotation mechanisms.
Innovation Solution
A side stabilizer design featuring a hollow body with a cylindrical element and a fluid-dynamically adjustable locator element, protected by a tubular conformational protection element, which ensures proper sealing and simplifies manufacturing by using elastic contrast means and anti-rotation mechanisms that prevent accidental rotation and debris accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical blocking means are used to control the cylindrical element's position, then the stabilizer can prevent or allow relative movement between the hollow body and cylindrical element, but the device becomes complex to manufacture due to precise machining tolerances required for the blocking member, hollow body, and cylindrical element
Solution Approach 1:
The patent replaces the mechanical blocking means with a fluid-dynamic system. A locator element is positioned within a chamber that communicates with the external environment through a可控 opening. By controlling the fluid pressure (hydraulic or pneumatic) in the chamber, the locator element can be moved to block or allow the relative movement between the hollow body and cylindrical element, eliminating the need for complex mechanical blocking members with precise machining tolerances
Solution Approach 2:
The patent explicitly uses hydraulic or pneumatic pressure to control the position of the locator element. The chamber is communicated with the external environment through a可控 opening that allows fluid pressure to be applied. This fluid pressure system provides a simple and reliable way to control the stabilization function without complex mechanical parts
2Adaptability or versatility
If hydraulic blocking means are used to adjust the locator element position, then the end-of-stroke position can be adjusted, but the lateral surface of the locator element is exposed to external agents that could damage it and compromise sealing
Solution Approach 1:
The patent introduces a protection element in the form of a tube that surrounds the locator element. The locator element is nested within this protection tube, which is fixed to the hollow body. This nested structure protects the lateral surface of the locator element from external agents while still allowing the locator element to move axially within the protected space
Solution Approach 2:
The protection element is designed as a simple, robust tube that can be easily manufactured and replaced if needed. It serves as a sacrificial protective barrier that shields the critical locator element from damage by external agents
3Reliability
If the locator element is made mobile inside the hollow body to define end-of-stroke position, then fluid-dynamic adjustment is possible, but the locator element requires protection from external agents to maintain sealing surface finish
Solution Approach 1:
The protection element is designed as a simple tubular structure that surrounds the locator element. This nested configuration provides protection without adding significant complexity to the overall device structure
Solution Approach 2:
The protection element serves multiple functions: it protects the locator element from external agents, maintains the sealing surface finish, and does not interfere with the fluid-dynamic adjustment mechanism. It is fixed to the hollow body and provides a stable reference structure
