Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vehicle tires are used without conductor tracks, then the tire structure remains simple, but sensors cannot be connected to a central unit for integrated monitoring
Solution Approach 1:
The conductor track serves multiple functions: it provides electrical connection between sensors and central unit, supplies power to sensor elements, and enables integrated monitoring of multiple tire properties. This multi-functional approach increases adaptability without proportionally increasing complexity
Solution Approach 2:
The conductor track is integrated within the tire structure by placing it between the inner layer and the first carcass ply, nesting the electrical infrastructure within the existing tire layers. This allows sensor connectivity to be added without significantly altering the overall tire structure
2Ease of operation
If conductor tracks are arranged on the inside of the tire, then sensor connection becomes simple and flexible, but the tire manufacturing process becomes more complex
Solution Approach 1:
The conductor track is pre-positioned between the inner layer and the first carcass ply during tire manufacturing, before sensors are installed. This preliminary arrangement of the electrical infrastructure simplifies subsequent sensor installation and connection operations
Solution Approach 2:
The conductor track acts as an intermediary element that facilitates connection between sensors and the central unit. By providing a pre-established electrical pathway, it mediates the connection process and simplifies sensor installation without requiring complex routing during assembly
3Device complexity
If a single conductor track is used for both power supply and signal transmission, then the infrastructure remains simple, but signal interference and transmission errors may occur
Solution Approach 1:
The electrical infrastructure is segmented into separate conductor tracks: one dedicated to power supply and another dedicated to signal transmission. This segmentation prevents electrical interference between power and signal lines, improving signal transmission reliability while maintaining relatively simple infrastructure
Solution Approach 2:
Different regions of the tire monitoring system are assigned different electrical functions: the power supply conductor track provides energy to sensor elements, while the signal transmission conductor track carries data to the central unit. This functional differentiation ensures reliable operation by preventing interference

AI summary
To provide a vehicle tyre in which an infrastructure is provided for connecting individual sensors to one another or to a central device, it is suggested that at least one electrically conductive conductor track (2) is arranged in the peripheral direction of the vehicle tyre and so as to circle around said vehicle tyre, wherein a tyre module (3) having a central function is arranged in a first position on said conductor track (2) and, in at least one second position on the conductor track (2), at least one sensor (4, 5) is arranged for detecting tyre properties.
