Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If duration tests using tyre prototypes are performed, then high precision and high reliability are achieved, but the tests are very long in duration and very costly
Solution Approach 1:
The patent segments the testing system into two parts: a deformable support structure that replicates tyre component geometry and deformation characteristics, and a test device housing the electronic device. This segmentation allows the support to be specifically designed for accurate deformation replication while enabling independent optimization of each component, achieving high testing precision without requiring complete tyre prototypes.
Solution Approach 2:
The patent creates a simplified copy of the tyre component's deformation behavior through the deformable support. The support is designed to replicate the three-dimensional deformations and mechanical stresses that the actual tyre component experiences during vehicle operation, allowing accurate resilience testing without using the complete, expensive tyre prototype.
2Reliability
If duration tests using tyre prototypes are performed, then high precision and high reliability are achieved, but the tests are extremely costly due to manual manufacture
Solution Approach 1:
The testing system is divided into a deformable support structure and a test device housing. This segmentation allows the support to be manufactured separately using cost-effective methods while maintaining the geometric and mechanical properties needed for accurate testing, eliminating the need for expensive manual tyre prototype fabrication.
Solution Approach 2:
Instead of manufacturing complete tyre prototypes, the patent creates a simplified deformable support that copies only the essential deformation characteristics needed for testing. This copying approach dramatically reduces manufacturing complexity and cost while preserving testing accuracy.
3Reliability
If the electronic device is coupled to a tyre component, then it supplies information concerning tyre state, but during use the device is subjected to cyclical deformations that may cause fatigue fracture
Solution Approach 1:
The patent performs preliminary resilience testing by subjecting the electronic device to simulated cyclical deformations in the deformable support before the device is installed in the actual tyre. This preliminary action identifies potential fatigue fracture risks and device vulnerabilities under mechanical stress, allowing design improvements to be made before deployment.
Solution Approach 2:
The deformable support is designed to replicate the harmful cyclical deformations and mechanical stresses that the electronic device will experience during tyre operation. By beforehand cushioning or protecting the device through proper mounting design and material selection, the testing ensures the device can withstand the harsh operating environment without fatigue fracture.
4Productivity
If a test system uses a serpentine path with rollers, then tests are performed over short periods with reduced costs, but the deformations applied are different from actual tyre use conditions
Solution Approach 1:
The deformable support is designed with local quality variations that match the specific deformation characteristics of the tyre component being tested. Different regions of the support have different stiffness and deformation patterns that replicate the actual stress distribution and three-dimensional deformations experienced by the tyre component during vehicle operation, ensuring measurement precision while maintaining testing efficiency.
