Adjustable Tire Inflation Assembly with Pressure Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire inflation devices lack a pressure adjustment dial and electronic indicator to accurately inflate tires to a pre-determined pressure, leading to potential over- or under-inflation.
Innovation Solution
A tire inflation fitting with a pressure adjustment unit and light emitter that senses and alerts the user when the desired pressure is reached, using a rotatable adjustment dial and electronic pressure sensor integrated into the fitting, coupled with a light emitter to notify the user when the set pressure is achieved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a portable tire inflation device is used without a pressure adjustment dial and electronic indicator, then the device is simpler and cheaper, but the tire pressure cannot be precisely controlled leading to over- or under-inflation
Solution Approach 1:
The patent combines multiple functions into a single portable inflation device: a pressure adjustment dial for setting desired pressure, an electronic pressure sensor for measuring actual tire pressure, and a light emitter for visual feedback. This integration allows precise pressure control while maintaining portability and relative simplicity.
Solution Approach 2:
The device incorporates a light emitter that provides visual feedback to the user based on the pressure sensor's readings. When the tire pressure reaches the desired level set by the adjustment dial, the light indicator alerts the user, enabling precise pressure control without requiring the user to manually check pressure continuously.
2Ease of operation
If manual pressure checking is used without electronic indicators, then the device is simpler, but the user cannot accurately determine when the desired pressure is reached
Solution Approach 1:
The patent replaces manual pressure checking methods with an electronic pressure sensor and light emitter system. The electronic sensor continuously monitors tire pressure and the light provider instant visual feedback, eliminating the need for users to manually estimate or repeatedly check pressure with separate gauges.
Solution Approach 2:
The light emitter changes its state (on/off or color) to indicate when the target pressure has been reached. This visual signal system provides intuitive and accurate pressure status indication, making it easy for users to determine when inflation is complete without requiring technical knowledge or manual measurement.
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
Enables precise inflation of tires to any desired pressure without over- or under-inflation, ensuring accurate tire pressure maintenance.
Implementation Method 1
The pressure adjustment unit senses the pressure within the tire when the tire is being inflated with the tire inflation fitting
Implementation Method 2
A light emitter is coupled to the tire inflation fitting and the light emitter is turned on when the pressure adjustment unit senses air pressure within the tire inflation unit that matches the pressure to which the pressure adjustment unit is set

AI summary
An adjustable tire inflation assembly for precisely inflating a tire to a desired pressure includes a tire inflation fitting that is fluidly attachable to a valve stem on a tire for inflating the tire. A pressure adjustment unit is integrated into the tire inflation fitting that is settable between a minimum pressure and a maximum pressure. The pressure adjustment unit senses the pressure within the tire when the tire is being inflated with the tire inflation fitting. A light emitter is coupled to the tire inflation fitting and the light emitter is turned on when the pressure adjustment unit senses air pressure within the tire inflation unit that matches the pressure to which the pressure adjustment unit is set. In this way the light emitter alerts the user that the tire has been inflated to the desired pressure.
