Solution Overview
Problem
Existing luminous built-in elements for vehicle tires lack mechanical strength and have complex, costly installation methods, limiting their durability and widespread implementation.
Innovation Solution
A spike-based installation element with a light-emitting diode and translucent covering body embedded in the tire tread, utilizing a hard metal spike for mechanical protection and a plastic covering body for high visibility and simple installation, with options for symmetric or asymmetric placement and different LED colors for various warning functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If known built-in elements are used to improve vehicle visibility, then visibility is enhanced, but mechanical strength and durability are insufficient
Solution Approach 1:
The built-in element is segmented into a separate insert that fits within the spike structure, allowing the light-emitting component to be protected by the spike's hard metal body while maintaining optical functionality through the translucent covering
Solution Approach 2:
The spike body acts as an intermediary protective structure that shields the light-emitting diode and covering from mechanical stresses during driving, while the translucent covering allows light to pass through for visibility enhancement
2Illumination intensity
If known built-in elements are used to improve vehicle visibility, then visibility is enhanced, but installation complexity and cost increase
Solution Approach 1:
The insert is integrated into the existing spike structure, combining the light-emitting function with the already-proven spike design. This merging allows utilization of established spike attachment techniques while adding the visibility-enhancing LED component
Solution Approach 2:
The spike structure serves multiple functions: it provides mechanical protection for the light-emitting element, maintains attachment to the tire through established techniques, and enables visibility enhancement through the integrated insert with LED and translucent covering
