Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current TPMS setting tools face limitations in memory storage capacity, leading to incomplete protocol storage, inability to verify configuration accuracy during programming, and potential erroneous setting of nearby TPMS systems due to wireless transmission.
Innovation Solution
A TPMS setting tool with a housing, display unit, input device, and circuit board featuring a micro control unit, memory unit, low-frequency and radio-frequency communication units, and a wired connection port, allowing for direct programming of communication protocols and ID codes, ensuring accurate configuration verification and preventing interference with other TPMS systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used for TPMS programming, then the programming operation can be performed remotely, but the programming speed is slowed down and surrounding TPMSs may be accidentally altered
Solution Approach 1:
The patent introduces a wired connection interface as an intermediary between the setting tool and TPMS. This physical connection serves as a mediator that enables fast, reliable data transmission while preventing interference with surrounding TPMS systems, thus resolving the contradiction between remote operation convenience and programming speed/accuracy
2Ease of operation
If wireless transmission is used for TPMS configuration, then the setting tool can transmit protocols remotely, but surrounding TPMSs within signal range may receive and be erroneously set
Solution Approach 1:
The wired connection acts as a physical intermediary that establishes a dedicated communication channel between the setting tool and the target TPMS. This eliminates the risk of surrounding TPMS receiving erroneous signals while maintaining the ability to perform configuration operations, thus resolving the contradiction between operational convenience and configuration reliability
3Volume of stationary object
If memory space in TPMS is limited for storing communication protocols, then the device size is reduced, but the storage capacity for protocols is insufficient
Solution Approach 1:
The patent shifts the storage capacity dimension from the TPMS device itself to an external setting tool with expanded memory capabilities. This dimensional transfer allows the TPMS to remain compact while the external tool provides sufficient protocol storage space, resolving the contradiction between device size and storage capacity
4Ease of operation
If wireless programming is used, then the setting operation can be performed without physical contact, but immediate verification of programming success is not possible
Solution Approach 1:
The wired connection enables immediate feedback mechanisms where the setting tool can read back and verify the programmed data directly from the TPMS. This real-time feedback loop allows for instant confirmation of successful programming, resolving the contradiction between contactless operation convenience and verification accuracy

AI summary
A TPMS setting tool includes a housing carrying a display unit and an input device on the outside and a circuit board and a power supply device on the inside, the power supply device and the circuit board being electrically coupled together to provide the TPMS setting tool with the necessary working power supply. The housing has a receptacle provided at one side thereof and a connection port with multiple pins mounted inside the receptacle for the connection of a TPMS, enabling the desired communication protocol and ID code to be written into the inserted TPMS.
