Multi-Tire Air Hose Manifold for Uniform Tire Pressure Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for deflating and inflating vehicle tires are labor-intensive, time-consuming, and often result in inconsistent tire pressures, which can adversely affect driving performance and increase wear, especially when dealing with off-roading wheels that protect the air stem.
Innovation Solution
A hose kit with a manifold, air output hoses, tee fittings, tire whips, and locking air chucks that allow simultaneous and even deflation/inflation of multiple tires, equipped with a pressure gauge for real-time monitoring, using UV-resistant and freeze-resistant 3-layer PVC hoses with optimized dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual deflation/inflation of each tire is performed individually, then the driver can control each tire pressure, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The air hose kit is segmented into multiple independent hoses (first air hose, second air hose, third air hose, fourth air hose), each capable of connecting to a separate tire. This segmentation allows simultaneous operation on multiple tires while maintaining individual control over each tire's pressure adjustment process.
Solution Approach 2:
The kit merges multiple air hoses into a single integrated system that can be connected to an air source simultaneously. The manifold or central connection point allows all hoses to be filled or deflated at the same time, combining the functionality of multiple individual tools into one unified kit.
2Adaptability or versatility
If conventional air hose kits are used with simple air chucks, then the device complexity is low, but the air chuck cannot attach to protected air stems on off-roading wheels
Solution Approach 1:
The locking air chuck acts as an intermediary device between the air hose and the protected air stem. It features a collar that can be manually advanced to contact and engage with the air stem, bridging the gap created by the protective wheel design and enabling reliable connection.
Solution Approach 2:
The locking air chuck incorporates dynamic elements including a movable collar that can be advanced and retracted, and a locking mechanism that can engage and disengage. This dynamic design allows the device to adapt to the presence of protective wheel covers while maintaining a secure connection during pressure adjustment.
3Ease of manufacture
If the driver manually presses each valve pin, then no additional equipment is needed, but the driver must get down on knees four times which is hard work
Solution Approach 1:
The deflation process is made self-service through the locking air chuck design. When the collar is advanced to contact the air stem and the locking mechanism is engaged, the system automatically maintains the connection during deflation without requiring the operator to manually hold or press the valve pin, reducing physical effort.
4Ease of operation
If individual tire pressure adjustment is performed, then each tire can be controlled, but inconsistencies in tire pressures easily occur
Solution Approach 1:
The inclusion of a pressure gauge in the air hose kit provides real-time feedback on tire pressure during the inflation or deflation process. This allows the operator to monitor and adjust each tire to the desired pressure uniformly, ensuring consistent pressure across all tires while maintaining individual control.
