Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical contact charging is used, then charging connection is reliable, but vehicle movement is restricted
Solution Approach 1:
The patent replaces the mechanical contact-based charging system with a wireless electromagnetic induction system. The transmitting vehicle uses an induction mat that generates electromagnetic fields to wirelessly transfer energy to the receiving vehicle, eliminating the need for physical plugging and contact maintenance during motion.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary medium between the transmitting and receiving vehicles. The induction mat generates electromagnetic fields that couple with the receiving vehicle's charging system, enabling energy transfer without direct physical contact or line-of-sight requirements.
2Adaptability or versatility
If wireless charging is implemented, then vehicle autonomy is extended, but energy transfer efficiency decreases
Solution Approach 1:
The patent employs a dynamic extendable arm mechanism that actively adjusts the distance and positioning between the transmitting and receiving vehicles during charging. This dynamic adjustment optimizes the electromagnetic coupling efficiency in real-time, maintaining higher energy transfer efficiency despite the wireless nature of the system.
Solution Approach 2:
The patent changes key operational parameters including the distance between vehicles, the orientation of induction mats, and the power output levels to optimize energy transfer efficiency. The system monitors and adjusts these parameters dynamically to minimize energy loss while maintaining charging flexibility.
3Adaptability or versatility
If extendable arm mechanism is added, then wireless charging capability is enabled, but device complexity increases
Solution Approach 1:
The extendable arm mechanism serves multiple functions: it positions the induction mat for optimal coupling, maintains appropriate distance between vehicles, and can be retracted when not in use. This multi-functionality justifies the added complexity by providing versatile charging capabilities across different charging scenarios.
4Productivity
If continuous charging during motion is enabled, then operational efficiency is enhanced, but system reliability challenges arise
Solution Approach 1:
The patent incorporates feedback mechanisms that continuously monitor the charging status, distance between vehicles, and energy transfer efficiency. This feedback enables real-time adjustments to maintain stable and reliable charging operation during vehicle motion, preventing disruptions and ensuring consistent energy transfer.
