Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing writers for tire pressure sensors are inconvenient to use, requiring multiple types to accommodate different communication protocols and parameters for various vehicle manufacturers, leading to increased operational costs for repair shops.
Innovation Solution
A writer for tire pressure sensors featuring a housing with a receiving recess, a pivotable positioning member, and an ejection device that allows easy insertion, secure connection, and automatic ejection of the sensor, enabling one-handed operation and compatibility with multiple protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a writer for tire pressure sensor uses a simple structure, then the ease of operation is improved, but the reliability of connection and ejection is worsened
Solution Approach 1:
The positioning member is designed to be pivotable between a first position (abutting against the sensor to hold it securely) and a second position (releasing the sensor for ejection). This dynamic mechanism allows the writer to automatically transition from a secure connection state during programming to a release state for easy removal, resolving the contradiction between simple operation and reliable connection/ejection.
2Reliability
If the writer requires manual holding of the sensor during programming, then the connection stability is improved, but the ease of operation is worsened
Solution Approach 1:
The positioning member automatically performs the function of holding and releasing the sensor without requiring manual intervention. When the sensor is inserted, the positioning member pivots to the first position to secure it automatically. After programming, the user can easily eject the sensor by pivoting the positioning member to the second position, allowing the writer to serve itself in maintaining connection stability while preserving ease of operation.
3Reliability
If the writer uses a secure locking mechanism to hold the sensor, then the connection reliability is improved, but the ease of ejection is worsened
Solution Approach 1:
The positioning member transitions dynamically between a locked first position (providing secure connection reliability) and an unlocked second position (enabling easy ejection). This pivotable mechanism allows the writer to switch between secure holding and easy release states, resolving the contradiction between connection reliability and ease of ejection.
4Manufacturing precision
If the writer requires two-handed operation for sensor insertion and ejection, then the connection precision is improved, but the productivity is worsened
Solution Approach 1:
The positioning member automatically positions and secures the sensor upon insertion without requiring precise manual alignment. The automatic positioning and securing functions allow the sensor to be inserted and secured with one hand, while ejection is achieved by simply pivoting the positioning member with one hand, thereby improving productivity without sacrificing connection precision.

AI summary
A writer for a tire pressure sensor is disclosed, which is adapted to hold the tire pressure sensor to write a program to the tire pressure sensor. The tire pressure sensor has a first connection port. The writer includes a housing, a positioning member, and an ejection device. A surface of the housing forms a receiving recess, and a second connection port is provided in the receiving recess. When the tire pressure sensor is received in the receiving recess, the first connection port thereof is connected to the second connection port. The positioning member connected to the housing has a block section abutting against the tire pressure sensor to keep the first connection port being connected to the second connection port. The ejection device is adapted to exert a pushing force on the tire pressure sensor to eject it for separating the second connection port from the first connection port.
