Tire Shape Testing Device Using Overlapping Linear Light Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire shape testing methods face challenges in efficiently testing the surface shape of wide tires, particularly due to the increased complexity and cost of using multiple sensor heads and the need for dedicated linear light beams for each section, making it difficult to perform accurate shape tests on large tires.
Innovation Solution
A tire shape testing device that captures images of linear light beams irradiated on the tire's sidewall, shoulder, and tread sections using multiple linear light application means and image capturing means, allowing for the detection of surface shapes across a wide region without increasing the number of devices, by overlapping linear light beams and using a support mechanism to adjust installation positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple sensor heads are used to test the shoulder section, then the shape test coverage is improved, but the device complexity and cost increase
Solution Approach 1:
A single sensor head is designed to perform multiple functions by capturing images of different linear light beams (first, second, and third linear light beams) that illuminate different tire sections. The sensor head can detect both the shoulder section and sidewall section by receiving reflected light from multiple light sources, eliminating the need for multiple dedicated sensor heads while maintaining comprehensive test coverage.
2Area of stationary object
If multiple linear light beams are used to illuminate different tire sections, then the shape test coverage is improved, but the number of devices increases
Solution Approach 1:
Multiple linear light beams (first, second, and third linear light beams) are combined to illuminate different sections of the tire simultaneously. The first linear light beam illuminates the shoulder section, the second illuminates the sidewall section, and the third illuminates another region. A single sensor head captures reflected light from all three beams, merging their functions into one detection system, thereby covering the entire tire surface without increasing the number of devices.
3Measurement precision
If dedicated linear light beams are provided for each tire section, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
Each linear light beam (first, second, and third) is designed to illuminate specific tire sections with precise geometry, and a single sensor head universally detects reflected light from all beams. This multi-functional approach maintains high measurement precision for different tire sections while avoiding the need for dedicated detection devices for each light beam, thus reducing overall device complexity.
