Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic tire inflation systems (ATIS) fail to address overinflation issues, which negate their benefits of reduced tire failure, wear, and fuel economy, as they only prevent underinflation and do not provide pressure relief mechanisms for varying tire pressures based on load conditions or terrain.
Innovation Solution
A tire pressure maintenance device with a sensor mechanism to detect vehicle conditions and a control mechanism to apply predetermined pressures, including a relief mechanism to adjust tire pressure according to loaded/unloaded states and terrain, ensuring optimal tire performance and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ATIS delivers a prescribed pressure to tires to prevent underinflation, then tire failure and wear are reduced, but overinflation occurs causing increased stress on vehicle undercarriage and reduced adaptability
Solution Approach 1:
The system dynamically adjusts tire pressure based on real-time detection of vehicle load conditions through sensor mechanisms. The control mechanism switches between multiple pressure settings (e.g., 100 psi for empty state, 120 psi for loaded state) to optimize both reliability and adaptability, resolving the contradiction between preventing underinflation and avoiding overinflation stress.
Solution Approach 2:
The system changes the pressure parameter of the tire based on detected vehicle conditions. By maintaining a plurality of pressure settings and selecting the appropriate one based on load state, the system achieves both reliable tire operation and adaptability to different operating conditions, eliminating the harmful effects of fixed pressure delivery.
2Ease of operation
If a single prescribed pressure is delivered to tires, then the system is simple to operate, but it cannot provide optimal performance for varying load conditions and terrain
Solution Approach 1:
The system automatically detects vehicle load conditions through sensor mechanisms and self-adjusts tire pressure without requiring manual intervention. The control mechanism autonomously selects from multiple pressure settings based on detected conditions, maintaining ease of operation while achieving optimal performance adaptation to varying loads and terrain.
Solution Approach 2:
The system transitions from static single-pressure delivery to dynamic multi-pressure delivery, where the pressure setting automatically changes based on detected vehicle conditions. This dynamic adaptation maintains operational simplicity while significantly improving performance optimization for different load states and terrain conditions.
3Duration of action of stationary object
If tire pressure is increased for loaded vehicles to maintain optimal footprint, then tire life is extended, but vehicle undercarriage experiences increased stress
Solution Approach 1:
The system changes the tire pressure parameter based on vehicle load detection. For loaded vehicles, it increases pressure to 120 psi to extend tire life and maintain optimal footprint. For empty vehicles, it reduces pressure to 100 psi to minimize stress on the vehicle undercarriage, thereby resolving the contradiction between tire durability and undercarriage stress.
4Ease of manufacture
If ATIS only prevents underinflation, then the system is cost-effective, but it fails to address overinflation which negates its benefits
Solution Approach 1:
The system evolves from single-function underinflation prevention to multi-function tire pressure management that includes both underinflation prevention and overinflation control. By incorporating sensor mechanisms that detect vehicle load conditions and control mechanisms that deliver multiple pressure settings, the system maintains cost-effectiveness while significantly improving overall tire maintenance effectiveness and reliability.
