Agricultural Blade Tip Form-Fitting Connection Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blade tips for agricultural soil cultivation machines often experience functionality impairment due to the guide plate bending or peeling off under harsh conditions, leading to insecure fastening and reduced performance.
Innovation Solution
A blade tip design featuring a receptacle with a covering portion and form-fitting elements that prevent movement of the guiding element, ensuring secure attachment and absorption of forces through a combination of screw receptacles and form-fitting connections, including centering and ball attachments for alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a guide plate is used to cover the blade tip, then the blade tip is protected from soil material, but the guide plate may bend or peel off under harsh conditions
Solution Approach 1:
The guide plate is divided into multiple sections with individual fastening points, allowing each segment to be secured separately to the blade tip, preventing overall bending or peeling while maintaining protection functionality
Solution Approach 2:
Fastening elements are pre-positioned on the blade tip before the guide plate is attached, ensuring proper alignment and secure connection from the outset, preventing subsequent bending or peeling under operational loads
2Reliability
If the guide plate is securely fastened to the blade tip, then the connection is reliable, but the assembly process becomes more complex
Solution Approach 1:
Multiple fastening functions are combined into integrated fastening elements that simultaneously provide alignment, securing, and positioning capabilities, reducing the number of separate components and simplifying the assembly process while maintaining connection reliability
Solution Approach 2:
The fastening elements are designed to self-align and self-secure during assembly, eliminating the need for complex alignment procedures or additional adjustment steps, thereby simplifying assembly while ensuring reliable connection
3Ease of operation
If the guiding element is allowed to move freely in the receptacle, then insertion is easy, but the guiding element may bend or twist against the blade tip
Solution Approach 1:
The receptacle features localized form-fitting elements at specific positions that provide targeted restraint of the guiding element, allowing free insertion while preventing subsequent bending or twisting movements that would compromise reliability
4Object-affected harmful factors
If the receptacle is completely enclosed, then the guiding element is well protected, but insertion and assembly become difficult
Solution Approach 1:
The receptacle structure is segmented with strategically positioned openings that provide access for inserting the guiding element while maintaining enclosed protection on the sides exposed to soil material, achieving both protection and ease of insertion
