Mixing Tool Scraper Edge Adhesive Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mixing tools used for coarse-grained building materials like cement, mortar, or concrete suffer from rapid wear and damage due to contact with granular materials, leading to frequent repairs or replacements, especially the scraping edges which are subjected to extreme stress.
Innovation Solution
A mixing tool with a scraping section formed from a metallic core surrounded by a plastic jacket, where an adhesive is used to securely bond at least one hard metal element to the core, providing a firm connection and enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the scraping edge is formed without adhesive bonding, then the structure is simpler, but the service life is reduced due to rapid wear and damage
Solution Approach 1:
An adhesive layer is introduced as an intermediary substance between the scraping edge and the metallic core. This adhesive bonding agent creates a reliable connection that prevents rapid wear and damage, thereby extending the service life of the mixing tool while maintaining a relatively simple overall structure.
2Productivity
If the scraping edge is subjected to extreme stress, then the scraping function is effective, but the scraping edge is easily damaged and leads to rapid wear
Solution Approach 1:
The scraping tool employs a composite structure consisting of a metallic core surrounded by a plastic jacket, with the scraping edge bonded to the core via adhesive. This composite design allows the scraping edge to effectively withstand extreme stress during scraping operations while the adhesive bonding prevents easy damage and rapid wear, thereby maintaining both productivity and reliability.
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 adhesive bonding significantly extends the service life of the mixing tool by creating a strong and durable connection between the scraping edge and the metallic core, reducing wear and tear, and allowing for effective scraping without rapid damage.
Implementation Method 1
an adhesive is arranged between the at least one hard metal element and the metallic core, which glues the scraping edge to the scraping section
