Tire Pressure Sensor Rotating Stop Block Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire pressure sensor devices require complex and time-consuming assembly procedures due to the need for manual alignment and fastening of components, making the installation process cumbersome.
Innovation Solution
A tire pressure sensor device with a stop block and extension rod mechanism that allows for easy alignment and secure mounting by rotating the air valve between two angular positions, enabling simple assembly and disassembly through a through portion and recessed design, along with an adjustment nut for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a screw bolt and tool are used to fasten the tire pressure sensor and air valve together, then the connection strength is improved, but the assembly procedure becomes complicated and time-consuming
Solution Approach 1:
The patent extracts the fastening function from the traditional screw bolt mechanism and integrates it into the air valve body itself. The air valve body includes a threaded portion that directly engages with the mounting block, eliminating the need for separate fastening tools and procedures while maintaining secure connection.
Solution Approach 2:
The patent merges the air valve body with the fastening mechanism by incorporating a threaded portion directly into the air valve body structure. This integration combines the valve function and fastening function into a single component, simplifying the overall assembly procedure.
2Manufacturing precision
If manual alignment and fastening procedures are used, then the mounting precision is improved, but the assembly time is increased
Solution Approach 1:
The patent incorporates a positioning protrusion on the mounting block that aligns with a corresponding positioning groove on the air valve body before fastening. This preliminary positioning action ensures accurate alignment is achieved automatically during the fastening process, eliminating the need for separate manual alignment steps.
Solution Approach 2:
The patent segments the mounting interface into distinct functional elements: a positioning protrusion for alignment, a threaded portion for fastening, and a sealing surface for leakage prevention. This segmentation allows each function to be performed independently and efficiently during assembly.

AI summary
A tire pressure sensor device includes a tire pressure sensor (10) including a housing (21) and a mounting block (22) defining a through portion (25) in a coupling means thereof, and an air valve (30) including an extension rod (32) having a rod body (33) rotatably inserted through the through portion (25) and a stop block (34) located at one end of the rod body (33) and rotatable with the rod body (33) between a first angular position where the stop block (34) is kept in accurate alignment with the through portion (25) and axially movable with the rod body (33) through the through portion (25) for allowing separation between the tire pressure sensor (10) and the air valve (30) and a second angular position where the stop block (34) is stopped at the coupling means of the mounting block (22) in a staggered manner relative to the through portion (25) to prohibit separation between the tire pressure sensor (10) and the air valve (30).
