Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional height sensors mounted on suspension or air-spring systems are used to monitor vehicle load, then the system structure is simple, but measurement accuracy deteriorates due to uneven loading and cargo movement
Solution Approach 1:
The patent introduces an intermediary calculation method that uses measurable parameters (height, acceleration, steering angle) to derive load information indirectly through centrifugal force calculations, rather than directly measuring load with inaccurate sensors. This intermediary approach resolves the contradiction by providing accurate load assessment without requiring complex direct measurement systems.
Solution Approach 2:
The patent replaces the mechanical direct measurement approach (height sensors on suspension) with a computational mechanics approach using acceleration sensors and centrifugal force calculations. This substitution maintains simple hardware while achieving accurate load measurement through physics-based calculations.
2Ease of manufacture
If height measurement methods are used to monitor vehicle load, then the monitoring system is simple to implement, but safety deteriorates due to undetected uneven load distribution and centrifugal force effects
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors acceleration, steering angle, and height data to calculate centrifugal force and detect unsafe loading conditions. This feedback loop provides real-time safety assessment while maintaining simple implementation through existing vehicle sensors, resolving the contradiction between ease of implementation and safety reliability.
Solution Approach 2:
The patent uses centrifugal force calculation as an intermediary parameter that connects easily measurable quantities (acceleration, steering angle) to safety-critical load distribution information. This intermediary approach enables simple implementation while achieving reliable safety monitoring.
3Quantity of substance
If conventional load monitoring systems are used, then the system cost is low, but the ability to prevent fishtailing and jack knifing deteriorates due to inability to detect centrifugal force effects
Solution Approach 1:
The patent makes existing vehicle sensors (acceleration sensors, steering angle sensors, height sensors) serve multiple functions: traditional vehicle control and the new centrifugal force calculation for load monitoring. This multi-functionality provides advanced centrifugal force detection capability without increasing system cost, resolving the contradiction between low cost and adaptability.
