Buffer Brush Air Cooling Design to Extend Tire Buffing Tool Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire buffing processes face challenges in efficiently removing tread material and achieving the desired surface texture on tire casings, leading to issues with tread adhesion and longevity due to inadequate buffing of shoulder areas.
Innovation Solution
A buffer brush design featuring a core with lateral and radial air flow openings and vents, which, when rotated, acts as a centrifugal pump to cool the bristles, extend brush life, and remove dust, while maintaining precise control over buffing operations to achieve uniform texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If buffer brushes are used frequently for tire buffing operations, then productivity is improved, but the brush wears out and must be replaced frequently
Solution Approach 1:
The patent introduces an air cooling system with openings in the brush core and end plates that allow air to flow through the brush during rotation. This pneumatic cooling mechanism removes heat generated during buffing operations, preventing bristle overheating and degradation, thereby extending brush service life while maintaining continuous productivity
Solution Approach 2:
The patent modifies the physical structure of the brush by adding specific opening configurations to the core and end plates, changing the thermal management parameters of the brush system. This structural parameter change enables effective heat dissipation without compromising the brush's mechanical performance or buffing capability
2Duration of action of moving object
If air flow openings are added to cool the brush, then brush life is extended, but device complexity increases
Solution Approach 1:
The air flow openings serve multiple functions simultaneously: they cool the bristles during operation, allow dust and debris to escape from the brush core, and maintain structural integrity. This multi-functionality approach extends brush life without requiring separate cooling mechanisms, thereby limiting the increase in device complexity
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 buffer brush effectively extends the life of buffing tools, ensures consistent texture on tire casings, enhancing tread adhesion and retreaded tire longevity by maintaining precise control over buffing operations and dust removal.
Implementation Method 1
The buffer brush contains a core having a first side and a second side and the brush extends radially from the surface of the core. The first and second sides have at least one opening configured to allow air to flow laterally through the core. Vents on the surface of the core are configured to allow air flowing laterally through the core to also flow radially through the vents into the brush.
