Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric vehicles use batteries with limited energy storage, then the vehicle can operate cleanly without fuel, but the traveling range is limited and recharging is required frequently
Solution Approach 1:
The system performs preliminary actions by predicting future battery charge states and proactively identifying recharging opportunities before the battery is depleted. The power management apparatus continuously monitors battery state, forecasts charge levels based on driving patterns, and automatically seeks out recharging infrastructure in advance, preventing range anxiety and ensuring continuous operation.
Solution Approach 2:
The patent introduces an intelligent power management apparatus as an intermediary between the battery system and the external environment. This apparatus acts as a mediator that coordinates battery usage, predicts charge needs, communicates with recharging infrastructure, and automates the recharging process, thereby extending effective operating range beyond what simple battery capacity would allow.
2Quantity of substance
If recharging stations are deployed sparsely, then infrastructure cost is reduced, but availability of recharging during long trips or in remote areas becomes unreliable
Solution Approach 1:
The power management apparatus enables the vehicle to serve its own recharging needs autonomously. The system independently monitors battery state, predicts future charge requirements, identifies suitable recharging locations using navigation and infrastructure data, and executes recharging actions without requiring dense human-monitored station networks. This self-service capability makes the system resilient to sparse infrastructure deployment.
Solution Approach 2:
The system performs preliminary identification and preparation for recharging by forecasting battery charge states and proactively locating recharging infrastructure before it is needed. This advance planning allows the vehicle to reliably reach recharging points even in remote areas with sparse infrastructure, as the system prepares for recharging opportunities in advance rather than reacting to battery depletion.
3Duration of action of stationary object
If the vehicle continuously monitors battery state and seeks recharging opportunities, then uninterrupted operation is achieved, but system complexity and computational requirements increase
Solution Approach 1:
The power management apparatus autonomously performs all monitoring, prediction, and recharging coordination functions without requiring complex external control systems. The system self-manages battery state tracking, charge forecasting, infrastructure identification, and recharging execution, thereby achieving continuous operation through automated self-service rather than complex multi-system coordination.
Solution Approach 2:
The patent combines multiple functions (battery monitoring, charge prediction, navigation, infrastructure identification, and recharging control) into a single integrated power management apparatus. This merging of functions reduces overall system complexity compared to having separate specialized systems for each task, while still achieving uninterrupted operation through the coordinated capabilities of the unified apparatus.

AI summary
An apparatus, including a vehicle computer located at a vehicle which is an electric vehicle or hybrid vehicle; battery recharging equipment which includes a plug-in recharging system, an electric road inductive charging system, or an electric road electrified contact charging system, and a radio frequency identification (RFID) reader. The vehicle computer processes information and determines a battery charge level or a battery charge state for a battery of the vehicle. The RFID reader obtains information from a battery recharging system located at a battery recharging facility. The vehicle computer receives an activity report regarding the recharging of the battery by the battery recharging facility and displays information contained in the activity report. The activity report or information contained in the activity report is stored in a distributed ledger and blockchain technology system.
