Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In tyre manufacturing, the inaccurate control of moveable elements in machines leads to mechanical and structural issues in the final product, causing quality problems and potential damage to machinery due to improper positioning and force application during the deposition of strip-like elements.
Innovation Solution
A method and apparatus using a radiation emitter and detector to monitor the trajectory of building members, comparing the detected image with reference data to ensure precise movement and generate notification signals for real-time correction, employing a laser emitter and a detection device to track the movement of depositing members and verify their alignment and synchronism with other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If automated control of moveable elements is implemented in tyre manufacturing machines, then productivity and manufacturing precision are improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where the position of building members is continuously monitored during movement and compared against reference trajectories. Deviations are detected and used to generate corrective control signals, ensuring positioning precision without requiring overly complex preliminary control mechanisms.
Solution Approach 2:
The patent replaces complex mechanical positioning systems with an optical measurement system using electromagnetic radiation (laser) to track the position of building members. This substitution reduces mechanical complexity while maintaining or improving positioning precision through non-contact measurement.
2Measurement precision
If electromagnetic radiation emission is used to detect trajectory of building members, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The radiation emitter operates in periodic pulses rather than continuously, emitting electromagnetic radiation only when needed for trajectory detection. This periodic operation significantly reduces energy consumption while maintaining measurement precision by capturing position data at critical moments during the building member movement cycle.
