Tire Pressure Device Star-Shaped Protector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflation viewing devices for self-inflating vehicle tires are prone to damage when non-specialized personnel attempt to measure internal pressure without properly removing the device, leading to breaks in inner components.
Innovation Solution
The improved inflation viewing device features a protective star-shaped piece attached to the air entrance connector, a flexible conduit connection, and reduced components to prevent damage from improper tool insertion, allowing for safe pressure checking by non-specialized personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inflation viewing device is connected to the air source and inflation valve, then it enables monitoring of air circulation and tire inflation status, but it becomes vulnerable to damage when non-specialized personnel attempt to insert pressure gauges or tools through the connector
Solution Approach 1:
A protecting piece is introduced as an intermediary element between the air entrance connector and the internal filter/componentry. This protecting piece has a hollow body that receives and contains the filter, creating a protective barrier that prevents direct access to internal components while still allowing the device to function. Non-specialized personnel can operate pressure checking equipment through the protecting piece without damaging internal components.
Solution Approach 2:
The device is divided into distinct modular segments: the air entrance connector, the protecting piece, the filter, the plunger assembly, and the air exit connector. This segmentation allows the protecting piece to be independently positioned to shield internal components while maintaining the overall functionality of the device. The modular structure enables easy assembly and disassembly for maintenance.
2Measurement precision
If the device includes internal components like filters and plungers for monitoring air circulation, then it provides accurate tire inflation status, but the complexity of internal components increases the risk of damage from improper tool insertion
Solution Approach 1:
The protecting piece serves as a mediator that shields the filter and plunger assembly from external tools and improper handling. The hollow body of the protecting piece creates a protected space that allows the internal components to perform their monitoring function while being physically isolated from potential damage sources.
Solution Approach 2:
The protecting piece is installed beforehand to cushion and protect the internal components from potential damage. It acts as a pre-established protective barrier that absorbs or deflects any improper insertion attempts before they can reach the delicate filter and plunger assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively prevents damage to internal components and allows for efficient tire pressure checks by non-specialized operators, ensuring proper air circulation monitoring and tire identification without compromising the device's integrity.
Implementation Method 1
at least a spring held between the plunger and the seat of the main body

AI summary
An inflation viewing device has a main body which is externally provided with a transparent viewing portion and internally provided with an inner passage where an air path assembly is arranged. An air entrance connector is operatively connected to an external air source and to a first end of the main body. An air exit connector is connected to a second, opposed end of the main body and to an inflation valve. A guide spacer is provided between the air entrance connector and the main body. The guide spacer has an inner passage having a wider section in communication with the inner passage of the main body and a reduced section defining a communication opening with the air entrance connector. A filter is arranged in the communication opening. A plunger, biased by a spring, is slidably arranged within the inner passage of the guide spacer and guide section of the main body inner passage.
