Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contactless charging methods are used, then charging convenience is improved, but charging efficiency decreases and infrastructure cost increases
Solution Approach 1:
The patent introduces an intermediary mechanical contact system (conductive rails and sliding contacts) between the infrastructure and vehicle to transfer electrical energy. This mediator enables efficient power transfer through direct physical contact while maintaining ease of operation through automated contact mechanisms during normal driving conditions.
2Use of energy by moving object
If lithium-ion batteries with higher mass capacity are used, then energy storage autonomy is improved, but manufacturing and recycling environmental impact increases
Solution Approach 1:
The patent combines on-board battery storage with off-board infrastructure-based power delivery systems. This hybrid approach merges the advantages of both systems, allowing vehicles to use smaller batteries supplemented by dynamic charging from overhead or roadside conductive rails, thereby reducing the environmental burden of large battery manufacturing and recycling while maintaining energy autonomy.
3Reliability
If mechanical guidance systems with continuous rails are implemented, then trajectory control reliability is improved, but device complexity and infrastructure cost increase
Solution Approach 1:
The patent segments the guidance system into discrete modular components including sectional rails, standardized vehicle mounting points, and modular power transfer units. This segmentation allows the complex mechanical guidance system to be implemented in manageable sections, reducing overall infrastructure complexity while maintaining continuous trajectory control reliability through precise alignment of segments.
4Ease of operation
If driver vigilance is reduced in autonomous mode, then operational ease is improved, but safety risk increases due to system failures
Solution Approach 1:
The patent implements beforehand cushioning through redundant mechanical guidance systems and emergency stop mechanisms that are pre-positioned along the trajectory. These systems provide a safety buffer that activates automatically upon detecting failures in the primary autonomous control systems, allowing reduced driver vigilance while maintaining safety through multiple layers of pre-arranged protective measures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and efficient high-speed automated driving with reduced infrastructure costs, increased traffic capacity, and lower battery requirements, minimizing accidents and environmental impact while facilitating a gradual transition to automated driving.
Implementation Method 1
the friction that the emergency brake caliper exerts on the three surfaces of the rail can generate a braking force of more than 1 g, independently of the coefficient of adhesion between the wheel and the road
Implementation Method 2
retirable rollers, which make it possible, while traveling at cruising speed, to momentarily relieve the load on the wheels by taking support on an auxiliary rolling surface carried by the rail
