Soil Working Tool Spring Pivot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil working devices are prone to damage when the insertion tool hits hard objects in the soil, such as stones, and there is a need for lightweight and cost-effective manufacturing.
Innovation Solution
Incorporating a spring means into the returning mechanism that allows the insertion tool to pivot beyond its initial position when hitting a hard object, enabling it to evade the obstacle and preventing damage, while maintaining a lightweight design and allowing easy retrofitting of existing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insertion tool is made rigid and fixed in position, then it can effectively work the soil, but it is vulnerable to damage when hitting hard objects
Solution Approach 1:
The insertion tool is made dynamically adjustable through the spring means, allowing it to change its position and angle relative to the support arm. The spring enables the tool to pivot beyond the initial position when encountering hard objects, transforming the rigid structure into a dynamic system that can adapt to obstacles while maintaining effective soil working capability.
Solution Approach 2:
The spring means acts as a cushioning element that is pre-installed in the returning means. When the insertion tool hits a hard object, the spring absorbs the impact energy and allows the tool to pivot beyond the initial position, preventing damage before it can occur to the tool structure.
2Reliability
If a protection mechanism is added to prevent damage from hard objects, then the reliability improves, but the device weight increases
Solution Approach 1:
The spring means is integrated into the existing returning means, which already serves the function of returning the insertion tool to its initial position. By adding the spring component to this existing mechanism, the system gains protective cushioning functionality without requiring a separate protection mechanism, thereby minimizing weight increase.
Solution Approach 2:
The spring means modifies the mechanical parameters of the returning means by introducing elastic deformation capability. Instead of adding a heavy rigid protection structure, the spring changes the force-displacement characteristics of the system, allowing energy absorption through controlled deformation while keeping the added weight minimal.
3Reliability
If the returning means is replaced with a spring-based system allowing movement beyond initial position, then the protection capability improves, but the device complexity increases
Solution Approach 1:
The spring means is merged with the existing returning means structure. Rather than creating a separate protection mechanism, the spring is integrated into the return system, combining the functions of returning the tool to initial position and providing cushioning protection. This merging approach maintains structural simplicity while achieving enhanced protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively protects the insertion tool from damage by allowing it to pivot around hard objects without interrupting operation, and the device remains only slightly heavier than previous models, with adjustable spring force for optimal performance.
Implementation Method 1
the returning means comprises a spring means in addition to the returning element, the spring means allowing the insertion tool to be pivoted in the second pivoting direction beyond the initial position
