Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire designs with electromagnetic transmitting and receiving devices, such as RFID systems, are not optimally configured, often exposing these devices to higher mechanical loads, which can compromise their functionality.
Innovation Solution
The electromagnetic transmitting and receiving device is strategically arranged in the shoulder area of the tire with a maximum distance of at most 2 mm from the shoulder pad, providing better protection from mechanical loads and optimizing its position for improved transmission and reception behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electromagnetic transmitting and receiving device is arranged in conventional tire areas, then the device can be easily integrated into the tire structure, but it is exposed to higher mechanical loads that compromise its functionality
Solution Approach 1:
The patent applies local quality by selecting a specific location (shoulder area) within the tire structure that has different mechanical load characteristics compared to other areas. The shoulder area experiences lower mechanical stresses and deformations during tire operation, making it a suitable location for housing sensitive electromagnetic components. This localized selection of quality (mechanical environment) resolves the contradiction by providing a protected niche within the overall tire structure.
Solution Approach 2:
The shoulder pad serves as an intermediary element between the electromagnetic device and the rest of the tire structure. By positioning the device in proximity to the shoulder pad (within 2 mm), the shoulder pad acts as a protective mediator that shields the device from direct mechanical loads while maintaining the device's integration within the tire. This intermediary structure resolves the contradiction by providing both protection and integration.
2Reliability
If the electromagnetic transmitting and receiving device is positioned closer to the shoulder pad, then the device is better protected from mechanical loads, but the distance to the rim increases which may affect transmission efficiency
Solution Approach 1:
The patent applies parameter changes by optimizing the distance parameter between the electromagnetic device and the shoulder pad. By specifying that the device be positioned within 2 mm of the shoulder pad, the patent finds an optimal parameter range that balances two competing requirements: sufficient proximity to the shoulder pad for mechanical protection, and adequate distance from the rim for effective electromagnetic transmission. This parameter optimization resolves the contradiction by identifying a sweet spot that satisfies both protection and transmission requirements.
