Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tire pressure monitoring systems face challenges due to the need for unique communication protocols for different vehicle models, leading to high inventory costs and reduced service life due to exposure and corrosion, as well as the requirement for frequent battery replacement.
Innovation Solution
A tire pressure monitoring system that uses a wireless communication protocol storage method, where the communication protocol is downloaded from a cloud server and stored in the tire pressure monitor, allowing for universal compatibility and reducing the need for physical connectors, thus minimizing inventory and extending the device's lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unique communication protocols are stored for different vehicle models, then compatibility with specific vehicles is improved, but inventory costs and device complexity increase
Solution Approach 1:
The patent implements a universal tire pressure monitoring device that can work with multiple vehicle models by downloading and loading different communication protocols as needed. Instead of manufacturing different hardware for each vehicle model, a single device design serves multiple functions by dynamically adapting its communication protocol through software updates from a remote server.
Solution Approach 2:
The patent stores communication protocols as downloadable data on a remote server, allowing the device to copy and load the appropriate protocol for a specific vehicle model when needed. This eliminates the need to physically store multiple protocol versions in the device or maintain complex inventory of different device variants.
2Ease of manufacture
If physical connectors are used for protocol storage, then communication protocol can be written to the device, but corrosion and exposure reduce device lifespan
Solution Approach 1:
The patent replaces the mechanical connection system (physical connectors and wiring) with a wireless communication system. The device receives communication protocols and data wirelessly through electromagnetic signals, eliminating exposed metal connectors that would be susceptible to corrosion and extending the device's operational lifespan.
Solution Approach 2:
The patent introduces a wireless communication intermediary (radio frequency or other wireless transmission medium) between the external protocol source and the device. This intermediary allows protocol transfer without physical contact, protecting the device from corrosion while maintaining the ability to update and write protocols.
3Loss of information
If the wireless receiver remains active for protocol reception, then protocol updates can be received, but battery power is drained
Solution Approach 1:
The patent implements periodic or on-demand activation of the wireless receiver rather than keeping it continuously active. The receiver is activated only when protocol updates are needed or when triggered by specific conditions, allowing the device to maintain update capability while minimizing battery power consumption during normal operation.
Solution Approach 2:
The device includes a power management system that automatically controls the wireless receiver's activation based on operational needs. The system monitors conditions such as connection availability, update requirements, and battery status to intelligently determine when the receiver should be active, balancing protocol update capability with power conservation.
