Solution Overview
Problem
Existing communication systems for tyre service machines, such as wheel balancing machines, face challenges in installation, maintenance, and flexibility due to the need for physical cables and complex calibration processes, which hinder efficient operation and accuracy.
Innovation Solution
A wireless communication system using sensor-independent protocols allows for convenient exchange, expansion, and maintenance of measuring units, eliminating the need for physical cables and enabling autonomous operation of measuring units with integrated processing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If physical cables are used to transfer measurement signals from sensors to processing components, then data communication can be established, but the system becomes cumbersome to disconnect and remove during maintenance
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. Measurement signals are transmitted from sensors to processing components via wireless communication, eliminating physical cables and their associated connection complexity, thereby significantly improving ease of removal during maintenance while reducing overall device complexity.
2Ease of repair
If the entire measuring unit is replaced upon sensor failure, then system functionality is restored, but additional calibration work is required
Solution Approach 1:
The patent segments the measuring unit into independently replaceable sensor components and a processing component. When a sensor fails, only the specific sensor module needs to be replaced rather than the entire measuring unit. The processing component remains intact and can continue operating, eliminating the need for recalibration and significantly reducing replacement time.
Solution Approach 2:
The processing component is designed with universal interfaces and protocols that can work with different sensor types. This allows sensors to be replaced with different models or types without requiring recalibration of the processing component, as long as they communicate through the standardized wireless interface, thereby improving ease of repair while minimizing time loss.
3Reliability
If multiple sensors are integrated in one measuring unit, then data collection is comprehensive, but maintenance and replacement become difficult
Solution Approach 1:
The patent segments the measuring unit into multiple independently replaceable sensor modules, each designed to measure specific parameters. This modular architecture maintains comprehensive data collection capabilities while allowing individual sensors to be accessed, removed, and replaced easily without affecting other sensors, thereby resolving the contradiction between measurement accuracy and maintenance ease.
4Measurement precision
If sensors are calibrated with the rest of the tyre service machine after assembling, then measurement accuracy is ensured, but the process is time consuming
Solution Approach 1:
The patent implements preliminary calibration of sensor modules during their manufacturing process. Each sensor module comes pre-calibrated and tested before leaving the factory, with calibration data stored in its memory. When deployed in the tyre service machine, the modules simply need to register their pre-stored calibration parameters with the processing component, reducing on-site calibration time from hours to minutes while maintaining measurement accuracy.
