Removable Adapter for Combustion Tool Air-Fuel Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internal combustion fixing tools suffer from fouling over extended use, leading to reduced performance and longevity due to the need for complex and often neglected maintenance of fuel and air pathways, which involves deep cleaning and the use of powerful products.
Innovation Solution
A removable adapter for external air and fuel intake and mixing is introduced, which includes a venturi for air-fuel mixing, a fuel dosing device, and integrated filters, allowing for easy replacement and avoiding the need for deep tool cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the tool is used extensively, then productivity increases, but fouling of fuel and air pathways occurs leading to performance degradation
Solution Approach 1:
The patent divides the tool into modular components, specifically making the air filter removable and the fuel pathway components separable. This segmentation allows the air filter to be easily removed and cleaned by the user, and the fuel pathway to be flushed with solvent through removable caps, thereby maintaining performance during extended use without requiring deep disassembly or professional maintenance.
2Object-affected harmful factors
If deep cleaning operations are performed, then fouling is removed, but the tool must be immobilized and removed from service
Solution Approach 1:
The patent enables the operator to perform maintenance operations independently without requiring professional intervention or tool immobilization. The air filter can be quickly removed and cleaned by the user, and fuel pathway components can be flushed through simple cap removal and solvent injection, allowing maintenance to be performed in-field without stopping the tool's operational availability.
3Object-affected harmful factors
If integrated filters are added to the adapter, then air and fuel filtration is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the adapter component: it serves as the connection interface between fuel cartridge and combustion chamber, incorporates the air filter housing, and includes fuel pathway integration. This merging of functions into a single replaceable adapter unit actually simplifies the overall system by consolidating multiple components into one modular unit that can be serviced as a single assembly.
