Studded Tyre Stud Orientation via Artificial Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing studs in vehicle tires are inefficient in achieving differentiated roadholding effects in different directions, as they struggle to accurately determine and install studs of varying types and orientations to optimize braking, acceleration, and lateral stability.
Innovation Solution
The method employs artificial vision to identify patterns around stud holes, determining the suitable stud type and orientation for installation, using imaging devices and control units to ensure studs are installed with their main direction aligned appropriately, either parallel to the circumferential direction or rotation axis, thereby enhancing roadholding performance.

Engineering Contradiction Analysis
1Reliability
If different types of studs are installed in different orientations to optimize roadholding properties, then roadholding performance is improved, but the complexity of the installation process increases
Solution Approach 1:
The tyre is provided with patterns around stud holes before stud installation. These patterns pre-indicate the correct stud type and orientation for each hole, allowing the installation system to automatically select and install the appropriate stud without complex real-time decision-making, thus improving roadholding while managing installation complexity
Solution Approach 2:
An artificial vision system acts as an intermediary between the patterned tyre and the stud installation mechanism. The vision system reads the patterns and translates them into controlled stud selection and orientation, enabling automated precise installation without requiring manual intervention or overly complex mechanical systems
2Productivity
If manual installation methods are used for studs, then installation flexibility is maintained, but installation efficiency and precision decrease
Solution Approach 1:
The manual mechanical installation process is replaced with an automated system combining artificial vision and controlled stud placement. The vision system captures images of patterns around stud holes, processes this visual information to determine correct stud type and orientation, and controls the installation mechanism to precisely install studs in the correct orientation, thereby improving both efficiency and precision simultaneously
Solution Approach 2:
The tyre itself provides the installation instructions through patterns embedded around each stud hole. This self-contained information system eliminates the need for external complex programming or lookup tables, allowing the system to automatically determine the correct stud configuration for each hole based on the visual patterns present on the tyre

AI summary
A method for installing a stud in a tyre. The method includes identifying a stud hole for the stud in the tyre; imaging the vicinity of at least the stud hole, whereby information is received about the pattern in the vicinity of the stud hole, and using the received information to determine [i] the stud type suitable for the stud suitable in the stud hole and/or [ii] the suitable stud orientation of the stud suitable in the stud hole. The method includes providing a stud and installing it in a stud hole. The stud type of the stud is the same as the suitable stud type of a stud suitable in the stud hole; and/or the stud is installed in the stud hole in such a way that the main direction of the stud is parallel with the suitable stud orientation. Further a tyre studded by the method.
