Wireless Programming for Tire Pressure Detectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless programming methods for tire pressure detectors face interference issues when programming multiple detectors simultaneously, leading to missed identification codes and incomplete programming.
Innovation Solution
A method involving a wireless programmer that sends activating and stop-responding commands to manage tire pressure detectors, reducing signal interference by entering some detectors into a stop-responding mode, allowing for accurate identification and programming of all detectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless programming is used to program multiple tire pressure detectors simultaneously, then programming convenience is improved, but signal interference occurs causing identification codes to be missed
Solution Approach 1:
The patent segments the programming process into multiple time slots, where detectors that have not yet been programmed continue to respond to activation commands, while those already programmed are excluded from responding. This temporal segmentation prevents signal interference by ensuring only one detector responds at any given moment, thereby maintaining both wireless convenience and reliable code reception.
2Productivity
If all tire pressure detectors respond simultaneously to the activating command, then programming speed is improved, but wireless signal interference occurs
Solution Approach 1:
The patent implements periodic action by cycling through the programming process multiple times. In each cycle, the programmer sends an activation command, receives responses from unprogrammed detectors, sends stop-responding commands to those detectors, and repeats the process until all detectors are programmed. This periodic cycling maintains programming speed while eliminating signal interference through controlled sequential access.
3Productivity
If the programmer sends the code to all tire pressure detectors at once, then programming efficiency is improved, but code transmission accuracy deteriorates due to missed identification codes
Solution Approach 1:
The patent employs feedback mechanisms where the programmer receives identification codes from detectors in response to activation commands, uses this feedback to determine which detectors have been programmed, and sends stop-responding commands to prevent further responses from programmed detectors. This feedback loop ensures accurate code transmission to all detectors without interference, maintaining both efficiency and precision.

AI summary
A wireless programming method for tire pressure detectors includes the following steps. A wireless programmer sends an activating command. The tire pressure detectors send a responding message. The wireless programmer receives the responding messages and records identification codes in the received responding messages. The wireless programmer sends a stop-responding command to make the tire pressure detector with the identification codes, which is recorded in the wireless programmer, enter a stop-responding mode. The wireless programmer sends the activating command again. The tire pressure detectors not in the stop-responding mode send the responding messages. The wireless programmer receives the responding message and records the identification code in the received responding message. The wireless programmer sends a code to the tire pressure detectors corresponding to the recorded identification code to program the code. With such design, it could be ensured that the code could be sent and programmed into all the tire pressure detectors.
