Miter Sipe Machine With Pivoted Tread Support and Variable Sipe Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sipe cutting machines are limited to cutting sipes at a fixed angle and depth, which reduces their effectiveness as the tire tread wears down, and they fail to adapt to varying traction needs and tire types.
Innovation Solution
A sipe forming system with a pivotally coupled positioning assembly and cutting drum that allows for the formation of sipes at varying angles and depths, controlled by a computer system or manually, using a blade that is automatically sharpened during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed angle and depth cutting system is used, then the device complexity is reduced, but the adaptability to varying traction needs and tire types deteriorates
Solution Approach 1:
The cutting system employs a pivotally coupled positioning assembly that allows dynamic adjustment of the cutting drum angle relative to the tire tread. This enables the system to adapt to different tire types and traction conditions by varying the sipe cutting angle, while maintaining a relatively simple mechanical structure through the use of pivot joints and positioning devices rather than complex automated systems.
2Manufacturing precision
If the cutting drum is fixed, then the manufacturing precision is maintained, but the adaptability to tire wear deterioration deteriorates
Solution Approach 1:
The positioning assembly includes positioning devices that enable adjustment of the cutting drum's angular position as the tire tread wears down. This dynamic adjustment capability allows the system to maintain precise sipe cutting despite changes in tire condition, ensuring continued effectiveness of the sipes throughout the tire's service life.
Solution Approach 2:
The system changes the cutting parameters (angle and depth) by adjusting the positioning assembly's angular position. As the tire tread wears down, the positioning devices allow modification of these parameters to compensate for the wear, maintaining optimal sipe geometry and traction performance throughout the tire's usage period.
3Device complexity
If manual positioning is used, then the device complexity is reduced, but the productivity is decreased
Solution Approach 1:
The positioning assembly is pre-configured with positioning devices that guide the cutting drum to the correct angular position before cutting begins. This preliminary positioning ensures that the operator only needs to make minor adjustments rather than setting up the entire system from scratch, thereby maintaining simplicity while improving efficiency.

AI summary
A sipe forming system is provided. The sipe forming system includes a cutting base including a pivot plate having an aperture, a cutting drum extending at least partially through the aperture, a blade coupled to the surface of the cutting drum, and a mechanical power source operably coupled to the cutting base and configured to rotate the cutting drum. The sipe forming system further includes a positioning assembly pivotally coupled to the cutting base and configured to receive a tire tread. The positioning assembly includes a housing, the housing being selectively positionable relative to the pivot plate, and at least one positioning device configured to position the tire tread received by the positioning assembly with respect to the cutting drum.
