Resilient-Mount Soil Processing Tools for Twisting Stress Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural soil processing tools experience premature deterioration due to stresses acting in various directions, including vertical and transverse components, leading to structural weakness in their connection to the frame.
Innovation Solution
A device with a resilient element connected to the frame via laminar elements and a separator device forming a cavity, allowing bending movements to absorb and distribute stress, reducing twisting moments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional direct connection of processing tools to the frame is used, then the structure is simple, but the tools suffer from premature deterioration due to multidirectional stresses including twisting moments
Solution Approach 1:
The connection structure is segmented into multiple functional components: resilient elements (leaf springs) that absorb vertical stresses, separator devices that create cavities to prevent twisting moment transmission, and laminar elements that provide additional structural support. This segmentation allows each component to address specific stress types independently, improving tool reliability without creating an overly complex integrated system.
Solution Approach 2:
The resilient element acts as an intermediary between the processing tool and the frame, absorbing vertical stresses and preventing them from being transmitted directly to the tool mounting. The separator device serves as another intermediary by creating a cavity that prevents twisting moments from reaching the tool connection points, thereby protecting the tool from premature deterioration.
2Strength
If resilient elements are used to connect tools to the frame, then vertical stress resistance is improved, but transverse stresses and twisting moments still cause premature deterioration
Solution Approach 1:
The separator device is strategically positioned at the critical location where the resilient element connects to the frame, creating a localized cavity that specifically addresses the twisting moment problem. This local intervention prevents transverse stress transmission without compromising the overall vertical stress absorption capability of the resilient element, thereby improving tool connection durability.
3Reliability
If the connection structure is made more complex to resist multidirectional stresses, then tool life is improved, but the device complexity increases
Solution Approach 1:
The separator device changes the geometric parameter of the connection structure by introducing a cavity between the resilient element and the frame. This geometric modification allows the structure to accommodate transverse movements and twisting moments without requiring complex additional components, thereby improving tool life while maintaining relatively simple device architecture.
