Problem
Conventional manual tire siping methods are labor-intensive, require significant strength and precision, and often result in non-uniform sipes, posing safety risks and reducing traction and skid resistance.
Innovation Solution
An automatic sipe forming machine that adjusts sipe angles, depths, and shapes, accommodating various tire sizes and wheel offsets, utilizing a tire supporting apparatus and sipe forming apparatus with adjustable mechanisms for precise and efficient sipe creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual siping method is used, then operator can form sipes on tread face, but it requires several hours and significant strength and precision, resulting in non-uniform sipes
Solution Approach 1:
The patent replaces the manual mechanical system with an automated mechanical system. The automatic siping machine uses a motor-driven rotating cutter assembly that automatically feeds the tire and positions cutting knives to form uniform sipes without manual intervention, eliminating the time and precision requirements of manual operation.
Solution Approach 2:
The automatic siping machine performs self-positioning and self-adjustment during operation. The rotating cutter assembly automatically maintains proper cutting depth and angle through its mechanical design, and the feed mechanism automatically advances the tire at controlled rates, eliminating the need for continuous manual adjustment.
2Reliability
If manual siping operation is performed, then sipes can be formed on tire, but it poses safety risks due to repetitive use of extremely sharp knife over hard surface
Solution Approach 1:
The patent replaces the dangerous manual mechanical system with an automated mechanical system. The sharp cutting knives are mounted on a motor-driven rotating assembly that automatically performs the cutting action, eliminating direct operator contact with the sharp blades and the hard tire surface, thereby removing the safety risks entirely.
3Adaptability or versatility
If adjustable sipe angles and tire size accommodation are implemented, then machine can handle wide range of applications, but device structure becomes more complex
Solution Approach 1:
The patent employs dynamic, adjustable components rather than fixed structures. The cutter assembly rotates on multiple axes with adjustable positions, allowing the cutting knives to be positioned at various angles and depths. The feed mechanism also allows adjustable feed rates, enabling the same machine to handle different tire sizes and siping patterns through dynamic adjustment rather than multiple fixed configurations.
