Demolition Tool Tip Adapter Force Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Demolition tools experience rapid wear on surfaces engaging abrasive or hard materials, leading to increased maintenance and reduced tool lifespan due to the lack of effective wear reduction strategies for adapters during crushing and cutting operations.
Innovation Solution
A replaceable tip with a specific design featuring first, second, and third abutment surfaces and a channel configuration that directs resultant demolition forces perpendicular to the adapter, reducing wear on the adapter and extending tool lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wear parts are connected directly to the jaw set by conventional techniques, then the wear part can be retained during operation, but the fasteners are exposed to relatively high stresses during operation leading to rapid wear
Solution Approach 1:
The patent introduces an adapter as an intermediary component between the jaw set and the wear part (tip). The adapter includes a body with engagement surfaces that mate with the tip, and it is connected to the jaw set through fasteners. This intermediary structure protects the fasteners from direct exposure to high demolition forces, as the adapter body absorbs and distributes these forces through its engagement surfaces with the tip.
Solution Approach 2:
The patent divides the wear protection system into separate components: the jaw set, the adapter, and the tip. The adapter is a distinct segment that interfaces between the jaw set and the tip, allowing each component to be optimized independently. The adapter body specifically handles the mechanical interface and force distribution, while the tip focuses on wear resistance.
2Reliability
If the adapter is designed with multiple engagement surfaces and a channel configuration, then the resultant demolition force is directed perpendicular to the adapter reducing wear, but the device complexity increases
Solution Approach 1:
The patent redirects the force transmission path by introducing a channel within the adapter body that directs the resultant demolition force in a direction perpendicular to the adapter's main axis. This dimensional redirection of force flow allows the engagement surfaces to be optimized for wear resistance while the channel manages the force vector, effectively separating the wear interface from the primary load path.
Solution Approach 2:
The channel structure within the adapter body acts as an intermediary force transmission path. It mediates between the engagement surfaces that contact the tip and the fasteners that connect to the jaw set, directing forces through a controlled path that reduces wear on the engagement surfaces while maintaining structural integrity.
