Automated Tire High Point Marking via Decoupled Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for marking the high point on vehicle tires are inefficient as they require the measuring machine to perform both measurement and marking tasks, limiting accuracy and increasing cycle time, and do not allow for independent processing of these steps.
Innovation Solution
A method where the high point on a vehicle tire is measured using a measuring machine, aligned on a conveyor, and then photographed or video recorded to determine its angular position relative to a sidewall identification mark, allowing for decoupling of measurement and marking processes, with the automated marking station applying an optical mark based on stored data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the measuring machine performs both measurement and marking tasks, then the process is integrated, but the cycle time increases and accuracy is limited
Solution Approach 1:
The patent divides the measurement and marking processes into separate independent steps. The measuring machine only performs measurement tasks, while the marking is performed later by a different system (conveyor belt with marking device), thereby reducing cycle time and improving accuracy without requiring complex integration of marking devices into the measuring machine.
Solution Approach 2:
The patent implements preliminary measurement and data storage before the marking operation. The measuring machine measures the high point position and stores the data, then the tire is conveyed to the marking station where the pre-acquired data is used for accurate marking. This separation allows optimized measurement and marking operations independently.
2Ease of operation
If the measuring machine is equipped with marking devices, then marking can be performed immediately, but the measuring machine complexity increases and marking accuracy is compromised
Solution Approach 1:
The patent extracts the marking function from the measuring machine. The measuring machine focuses solely on precise measurement of the high point position, while the marking operation is performed separately by a dedicated marking system using the measured data, thereby maintaining measurement precision without compromising ease of operation.
3Measurement precision
If photo/videorecording is used to determine angular position, then measurement accuracy is improved, but additional equipment is required
Solution Approach 1:
The patent replaces complex mechanical measurement systems with optical recording methods. Instead of using mechanical sensors and gauges to determine angular position, the system uses photo or videorecording to capture the tire position, then processes the images computationally to achieve high measurement precision with simpler, more flexible equipment.

Function Achieved in This Case
This approach enables accurate and independent measurement and marking of the high point, eliminating the need for marking devices on the measuring machine, increasing cycle efficiency, and allowing for high-speed marking at the automated station.
Implementation Method 1
creating a photo or video recording of the vehicle tire resting on the conveyor, with the photo or video recording being used to measure the relative angular position of the highest point of the vehicle tire in relation to an identification means arranged on the side wall
