Engineering Contradiction Analysis
1Manufacturing precision
If existing methods for applying additional components are used, then the deposition process is simple, but the uniformity and precision of deposition are poor
Solution Approach 1:
The patent performs a preliminary scan of the tire internal surface to generate a mathematical model before deposition begins. This preliminary action allows the system to anticipate surface irregularities and adjust deposition parameters in advance, ensuring uniform deposition without requiring complex real-time intervention mechanisms.
Solution Approach 2:
The patent implements a feedback mechanism where the mathematical model of the tire surface is continuously referenced during deposition. The control unit adjusts deposition parameters based on the mathematical model data, creating a closed-loop control system that maintains high precision without excessive complexity.
2Manufacturing precision
If existing deposition methods are used, then the process is flexible, but the control over deposition parameters is inadequate
Solution Approach 1:
The patent employs dynamic adjustment of deposition parameters including distance, orientation, and flow rate based on the mathematical model of the tire surface. The system adapts these parameters in real-time during deposition to maintain precision while preserving process flexibility through programmable control.
Solution Approach 2:
The patent systematically changes multiple deposition parameters (distance from nozzle to surface, orientation of nozzle, flow rate of material) based on the mathematical model data. This coordinated parameter adjustment achieves precise control while maintaining adaptability through the flexibility of the control system.
3Manufacturing precision
If uniform deposition is achieved through manual adjustment, then the equipment is simple, but the time consumption and labor are high
Solution Approach 1:
The system performs self-adjustment by automatically modifying deposition parameters based on the mathematical model of the tire surface. The control unit independently manages distance, orientation, and flow rate adjustments without requiring manual intervention, thereby achieving uniform deposition while maintaining high productivity.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated control system that uses the mathematical model to regulate deposition parameters. This substitution eliminates labor-intensive manual operations while maintaining or improving deposition uniformity and increasing overall efficiency.
4Manufacturing precision
If the dispensing nozzle is positioned closer to the internal surface for better coverage, then the deposition completeness improves, but the risk of imbalance and unevenness increases
Solution Approach 1:
The patent applies local quality by adjusting deposition parameters according to the specific characteristics of different areas of the tire internal surface. The mathematical model enables the system to optimize distance and flow rate for each local region, ensuring complete coverage while maintaining uniformity and balance across the entire surface.
Solution Approach 2:
The system dynamically changes deposition parameters including distance and flow rate based on the mathematical model data for different tire regions. This coordinated parameter adjustment ensures complete material coverage while preventing localized over-deposition that could cause imbalance.

AI summary
A plant (100) for building an additional component (12) within a vulcanised tyre (2) comprises a grip device (110), a scanning head (121) and a dispensing nozzle (122). After gripping the vulcanised tyre (2) with the grip device (110), the scanning head (12) performs a preliminary scan of a deposition portion of the internal surface (2a) of the tyre and, based on this preliminary scan, a control unit (140) generates a mathematical model. Subsequently, while the dispensing nozzle (122) delivers a continuous elongated element (E) on the deposition portion according to a spiral trajectory, the control unit (140) controls the deposition process by adjusting at least one deposition parameter according to the mathematical model of the deposition portion.
