Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintenance staff face challenges in communicating with tire pressure measurement devices installed on vehicles, as they often do not match with handheld detection devices, especially when the original manufacturer's service center is not nearby, leading to difficulties in diagnosing issues such as low tire pressure or device malfunctions.
Innovation Solution
A method using a look-up table with image codes corresponding to vehicle manufacture information to select the appropriate communication protocol, allowing handheld detection devices to communicate with tire pressure measurement devices, ensuring compatibility with the vehicle's electronic control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless tire pressure measurement devices are installed on vehicle tires, then driving safety is improved through continuous monitoring, but compatibility issues arise between handheld detection devices and tire pressure measurement devices from different manufacturers
Solution Approach 1:
The patent implements a universal communication protocol that enables handheld detection devices to communicate with tire pressure measurement devices from different manufacturers. The system uses standardized data transmission formats and protocols that are compatible across multiple device types, allowing a single handheld device to service multiple vehicle models and device generations.
Solution Approach 2:
The system dynamically adjusts communication parameters such as data transmission rate, packet format, and protocol version based on the detected tire pressure measurement device type. This allows the handheld detection device to adapt its communication characteristics to match the specific device being serviced, resolving compatibility issues without requiring device-specific hardware.
2Adaptability or versatility
If multiple communication protocols are supported for device compatibility, then adaptability is improved, but device complexity increases
Solution Approach 1:
The communication system dynamically selects and switches between different communication protocols based on the detected device type. Rather than implementing all protocols simultaneously in a static manner, the system activates only the necessary protocol for the current communication task, reducing overall system complexity while maintaining multi-protocol capability.
Solution Approach 2:
The patent introduces a protocol translation layer that acts as an intermediary between different communication protocols. This mediator converts data from various protocol formats into a standardized internal format, simplifying the complexity by centralizing protocol handling logic rather than requiring direct integration of multiple protocols throughout the system.
3Ease of operation
If maintenance staff use handheld detection devices at non-original service centers, then accessibility is improved, but communication failures occur due to protocol mismatches
Solution Approach 1:
The system performs preliminary protocol detection and configuration before attempting to communicate with the tire pressure measurement device. The handheld detection device automatically identifies the device type and configures the appropriate communication protocol in advance, ensuring reliable communication from the first attempt regardless of the service center location or device manufacturer.

AI summary
A method for setting tire pressure measurement device applicable for a detection device electrically couple to an image code scanner is provided. The method comprises the steps of: providing a look-up table (LUT) recording a plurality of image codes, each of the plurality of image codes corresponding to at least one piece of manufacture information, and the at least one piece of manufacture information corresponding to a vehicle; capturing one of the plurality of image codes by the image code scanner so as to generate a scanning result; and based on the scanning result, the detection device selecting one of a plurality of communication protocols.
