Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire testing machines face challenges with manual sensor positioning, resulting in inconsistent and potentially incorrect sensor placement due to the complexity and space requirements of known positioning devices, leading to unreliable test results.
Innovation Solution
A positioning device with two carriage units guided by a guide device, utilizing the kinematics of the tire testing machine's movable mounts to align the test sensor passively, eliminating the need for additional drives and ensuring accurate, reproducible sensor placement by coupling the sensor movement with the machine's existing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual sensor positioning is used, then the positioning device can be simple, but the sensor position cannot be set reproducibly resulting in inconsistent test results
Solution Approach 1:
The positioning device utilizes the existing movable holders and guide device of the tire testing machine to automatically position the test sensor. The carriage units are guided by the guide device and coupled to the movable holders, allowing the sensor positioning to be performed automatically by the machine itself without requiring additional complex positioning mechanisms or manual intervention.
Solution Approach 2:
The movable holders of the tire testing machine serve dual functions: they support the tire during testing and simultaneously drive the carriage units to position the test sensor. This multi-functionality eliminates the need for separate positioning drives while achieving automated, reproducible sensor placement.
2Reliability
If automated sensor positioning is implemented, then reproducible sensor placement is achieved, but the positioning device becomes complex in terms of control technology and mechanics
Solution Approach 1:
The positioning device utilizes the existing movable holders and guide device of the tire testing machine to automatically position the test sensor. The carriage units are guided by the guide device and coupled to the movable holders, allowing the sensor positioning to be performed automatically by the machine itself without requiring additional complex positioning mechanisms or manual intervention.
Solution Approach 2:
The positioning function is merged with the existing holder movement system. The carriage units are mechanically coupled to the movable holders, combining the holder positioning function with the sensor positioning function into a single integrated system, thereby eliminating additional complexity.
3Extent of automation
If additional drive mechanisms are added for sensor positioning, then automated positioning is achieved, but the mechanical complexity and space requirements increase
Solution Approach 1:
The positioning device utilizes the existing movable holders and guide device of the tire testing machine to automatically position the test sensor. The carriage units are guided by the guide device and coupled to the movable holders, allowing the sensor positioning to be performed automatically by the machine itself without requiring additional complex positioning mechanisms or manual intervention.
