Parallel Tire Inflation Flow Path for Faster Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art tire inflation systems for heavy-duty vehicles have reduced flow capacity due to flow detection devices, leading to longer times to achieve target pressure, potentially causing increased tire wear and damage from improper inflation.
Innovation Solution
A tire inflation system with a high-capacity parallel fluid flow path and a flow detection device that includes a low-capacity conduit with a flow switch and a high-capacity conduit with a valve, allowing for rapid inflation and deflation by adjusting fluid flow based on pressure differentials, preventing restrictions in the fluid path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a flow detection device is disposed within the inflation fluid path, then flow detection capability is provided, but system flow capacity is reduced
Solution Approach 1:
The system is divided into two separate parallel conduits: one dedicated to flow detection (low-capacity) and one dedicated to high-volume fluid transport (high-capacity). This segmentation allows the flow detection device to function without restricting the overall system flow capacity, as the detection conduit operates independently from the main inflation pathway.
Solution Approach 2:
A parallel low-capacity conduit acts as an intermediary pathway that allows the flow detection device to monitor fluid flow without being part of the main high-capacity inflation path. The detection conduit provides the necessary flow sensing capability while the high-capacity conduit handles the bulk fluid transport, eliminating the restriction problem.
2Measurement precision
If the system uses a single fluid path with flow detection device, then flow can be monitored, but the time to achieve target pressure increases
Solution Approach 1:
By segmenting the fluid path into parallel detection and high-capacity conduits, the system enables simultaneous flow monitoring and high-speed inflation. The high-capacity conduit eliminates flow restrictions, reducing the time to achieve target pressure while the detection conduit maintains monitoring accuracy.
Solution Approach 2:
The parallel conduit configuration allows continuous, unrestricted high-capacity fluid flow to reach the tires while simultaneously providing continuous flow detection. This eliminates interruptions or flow restrictions that would otherwise extend the inflation time, maintaining both monitoring capability and rapid inflation performance.
3Difficulty of detecting and measuring
If flow detection device is placed in-line, then flow can be detected, but tire inflation time is extended
Solution Approach 1:
The in-line flow detection device is segmented into a separate parallel low-capacity conduit, allowing it to perform detection functions without extending the inflation duration. The high-capacity conduit provides an unrestricted pathway for rapid tire inflation, while the detection conduit maintains its monitoring function independently.
Solution Approach 2:
The parallel detection conduit serves as an intermediary that enables flow detection without being part of the main inflation flow path. This intermediary configuration allows the system to detect flow accurately while maintaining short inflation times through the high-capacity conduit.
