Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If colored dots are used to indicate tire uniformity, then visual indication of uniformity is achieved, but the system becomes complex and prone to failure
Solution Approach 1:
The patent replaces physical colored dots with their digital representation stored in a database associated with the RFID chip. The imaging system captures the actual colored dot positions, converts them to coordinate data, and stores this digital copy. During mounting, the digital coordinates are retrieved and displayed on a screen, eliminating the need for physical markers while maintaining the visual indication function.
Solution Approach 2:
The patent substitutes the mechanical system of physical colored dots with an electronic/digital system comprising RFID chips, imaging systems, databases, and display screens. The RFID chip stores uniformity data electronically, replacing the need for physical visual markers, thereby reducing complexity and increasing reliability.
2Productivity
If colored dots are used for tire uniformity indication, then mounting guidance is provided, but time is lost when dots peel off
Solution Approach 1:
The patent creates a digital copy of the colored dot information stored in the RFID chip and database. This digital representation does not suffer from physical degradation like peeling. The mounting technician can access this permanent digital record through the imaging system and display, ensuring continuous availability of mounting guidance without time loss.
Solution Approach 2:
The system automatically captures the colored dot positions using the imaging system and stores them in the database associated with the RFID chip. This automated process eliminates manual recording and ensures the information is always available without requiring physical markers that can fail.
3Loss of information
If barcode is used as reference for storing measurement position, then data storage is achieved, but the barcode is not visible during tire and rim assembly
Solution Approach 1:
The patent transitions the information from a two-dimensional physical barcode on the tire surface to a digital dimension stored in the RFID chip and database. This allows the information to be accessed in multiple ways: the actual colored dots remain visible on the tire during assembly, while their digital coordinates can be viewed on a separate display screen, providing flexibility in information access.
Solution Approach 2:
The patent introduces an imaging system and display screen as intermediaries between the stored uniformity data and the mounting technician. Instead of requiring direct visibility of the reference marker during assembly, the system captures the colored dot positions, stores them digitally, and presents them on a display, allowing the technician to reference the information without physical markers being visible on the tire.
