Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tire pressure monitoring devices require complex and time-consuming programming specific to each vehicle type, necessitating extensive storage space for numerous programs and requiring access to internet or computer resources, making them difficult to use and costly for aftermarket applications.
Innovation Solution
A method where a basic program version is stored in the device, allowing adaptation to specific vehicle types by loading minimal program parameters, typically 10-30 bytes, using a hand-sized device that transmits digital command signals wirelessly or wired, utilizing a lower frequency range to ensure precise and error-free adaptation, reducing storage needs and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tire pressure monitoring device stores numerous complete programs for different vehicle types, then it can be adapted to various vehicle types, but it requires a great deal of storage space
Solution Approach 1:
The patent divides the complete vehicle-specific program into two segments: a basic program that is universally applicable and vehicle-specific parameter sets that contain only the necessary configuration data. This segmentation allows the device to store multiple vehicle type configurations without requiring full program copies for each vehicle type, thereby reducing storage space while maintaining adaptability.
Solution Approach 2:
The patent extracts only the essential vehicle-specific parameters from complete programs and stores them separately in a compact parameter set. This extraction approach eliminates redundant code and data that would otherwise be duplicated across multiple vehicle type programs, significantly reducing the storage space required while preserving the ability to adapt to different vehicle types.
2Adaptability or versatility
If a universal tire pressure monitoring device is programmed with vehicle-specific software, then it can be used for different vehicle types, but the programming process is very complex and time-consuming
Solution Approach 1:
The patent prepares vehicle-specific parameter sets in advance and stores them in a compact format. During adaptation, the system only needs to load and activate the appropriate parameter set for the target vehicle type, rather than performing complex programming operations. This preliminary preparation of parameter sets dramatically reduces the time required for vehicle type adaptation.
Solution Approach 2:
The patent uses a copying mechanism where a complete program is split into a universal basic program and vehicle-specific parameter sets. The basic program remains constant and is copied to all devices, while only the small parameter sets need to be transferred and adapted for different vehicle types. This copying approach simplifies the adaptation process from complex reprogramming to simple parameter loading.
3Adaptability or versatility
If complete programs are transferred to the tire pressure monitoring device, then the device is fully configured for a vehicle type, but the transmission scope is typically a few tens of kilobytes which is large for wireless transfer
Solution Approach 1:
The patent extracts only the essential vehicle-specific parameters from complete programs and stores them separately in a compact parameter set. This extraction approach eliminates redundant code and data that would otherwise be duplicated across multiple vehicle type programs, significantly reducing the storage space required while preserving the ability to adapt to different vehicle types.
Solution Approach 2:
The patent divides the complete vehicle-specific program into two segments: a basic program that is universally applicable and vehicle-specific parameter sets that contain only the necessary configuration data. This segmentation allows the device to store multiple vehicle type configurations without requiring full program copies for each vehicle type, thereby reducing storage space while maintaining adaptability.
4Reliability
If a tire pressure monitoring device is adapted to a specific vehicle type with complete programming, then it meets vehicle manufacturer specifications, but it requires access to internet or computer resources and complex programming stations
Solution Approach 1:
The patent uses a copying mechanism where a complete program is split into a universal basic program and vehicle-specific parameter sets. The basic program remains constant and is copied to all devices, while only the small parameter sets need to be transferred and adapted for different vehicle types. This copying approach simplifies the adaptation process from complex reprogramming to simple parameter loading.
Solution Approach 2:
The patent enables the tire pressure monitoring device to be adapted using a simple handheld device that the end user can operate without requiring access to internet resources, computer programming stations, or specialized equipment. The system performs the adaptation process itself by loading pre-prepared parameter sets, making the device self-sufficient and eliminating the need for complex external programming infrastructure.
