Agricultural Tire Pressure Control via Speed and Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote inflation systems for agricultural vehicles do not effectively account for the intrinsic characteristics of tires, leading to suboptimal performance in terms of energy consumption, traction, and soil compaction, as they primarily rely on pre-defined parameters and do not adapt in real-time to changing conditions such as tire characteristics, vehicle speed, and soil conditions.
Innovation Solution
A remote inflation system that determines the optimal tire pressure setpoint by reading tire identifiers, associating them with recorded characteristics, and calculating based on vehicle speed, tire design, and soil conditions, using sensors and databases to deliver precise inflation instructions for each tire, taking into account the position, load, and tool characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If tire pressure is increased to reduce rolling resistance and improve vehicle speed, then energy consumption decreases, but soil compaction increases and traction capacity is reduced
Solution Approach 1:
The patent implements dynamic tire pressure adjustment by continuously monitoring vehicle speed, soil conditions, and operational parameters, then automatically modifying tire pressure in real-time. The control unit receives data from sensors and adjusts pressure dynamically to optimize the balance between rolling resistance and soil compaction, rather than using fixed pressure settings
Solution Approach 2:
The system changes the physical parameter of tire pressure based on varying operational conditions. By adjusting pressure as a variable parameter rather than a constant, the system adapts to different soil types, vehicle speeds, and load conditions to minimize both energy consumption and soil compaction simultaneously
2Productivity
If tire pressure is increased to improve vehicle speed and reduce rolling resistance, then productivity increases, but traction capacity and grip are reduced
Solution Approach 1:
The system dynamically adjusts tire pressure based on real-time detection of vehicle speed, acceleration, and soil conditions. During high-speed travel on firm ground, pressure increases to reduce rolling resistance and improve productivity. During operations requiring high traction or on soft soil, pressure decreases to maximize grip and prevent slippage
Solution Approach 2:
The patent varies the tire pressure parameter according to the operational phase and ground conditions. The control unit modifies pressure settings to optimize the trade-off between speed-related productivity and force-related traction capacity, adapting continuously to changing requirements
3Device complexity
If remote inflation systems use pre-defined pressure parameters, then system complexity is reduced, but adaptation to real-time conditions and tire characteristics is insufficient
Solution Approach 1:
The system performs self-characterization by automatically detecting and storing tire-specific parameters such as stiffness, dimensions, and operational characteristics during initial use or through sensor feedback. This eliminates the need for manual configuration while enabling tailored pressure optimization for each tire, enhancing adaptability without proportionally increasing complexity
Solution Approach 2:
The patent incorporates feedback loops where sensors continuously monitor actual tire performance, vehicle dynamics, and soil conditions, and this information feeds back to the control unit which adjusts pressure settings accordingly. This closed-loop system enables real-time adaptation while maintaining manageable complexity through automated control algorithms
