Self-Repairing Tire Inflator Nozzle with Piercing Needle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle wheel inflator nozzles are difficult to access due to hubcaps, leading to challenges in accurately inflating or deflating self-repairing tires, which complicates pressure adjustments and may result in air leaks or improper inflation.
Innovation Solution
A new inflator nozzle design featuring a hollow needle with an adjustable protruding part that can be planted in a self-repairing zone of the tire, allowing for precise inflation or deflation, with a body connected to a gas pump and a fluid communication channel, and optionally including a sensor for tire thickness measurement to optimize needle height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard valve on the rim is used for inflation, then the tire can be inflated, but the valve is difficult to access due to hubcaps and requires secure positioning to prevent air leaks
Solution Approach 1:
The invention extracts the inflation function from the traditional rim-mounted valve and relocates it to the tire sidewall. The inflator nozzle pierces the tire sidewall directly, eliminating the need for access to the rim valve through the hubcap area. This extraction of the inflation access point from the rim to the tire sidewall resolves the contradiction by making the inflation point accessible while maintaining sealing through the piercing mechanism.
Solution Approach 2:
The inflator nozzle acts as an intermediary device that pierces the tire sidewall to create a direct fluid communication channel between the inflation source and the tire interior. This intermediary mechanism eliminates the need for a traditional valve assembly on the rim, providing both easy access (no hubcap interference) and reliable sealing (through the piercing action and nozzle design).
2Adaptability or versatility
If the needle protruding length is fixed, then the structure is simple, but it cannot adapt to different tire thicknesses
Solution Approach 1:
The invention applies dynamics by making the needle protruding length adjustable rather than fixed. The needle can be extended or retracted to match different tire sidewall thicknesses, allowing the same inflator device to work with various tire types. This dynamic adjustment capability resolves the contradiction between adaptability and complexity by introducing a controlled degree of flexibility.
Solution Approach 2:
The invention changes the parameter of needle protruding length from a fixed value to an adjustable variable. By allowing the needle length parameter to be modified according to the specific tire being inflated, the device achieves versatility across different tire thicknesses while maintaining a relatively simple overall structure through straightforward adjustment mechanisms.
