Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple charging devices are deployed to wirelessly charge multiple electric auxiliary vehicles, then each vehicle can be charged independently, but the system construction cost increases significantly
Solution Approach 1:
The patent makes the charging device universal by enabling it to serve multiple functions: it can charge multiple different electric auxiliary vehicles (wheelchairs, bicycles, scooters, motorcycles) using a single device through wireless power transfer, eliminating the need for dedicated charging devices for each vehicle type
Solution Approach 2:
The charging device automatically detects and adapts to different vehicle types and their power requirements, performing self-adjustment without manual intervention. The system identifies the connected vehicle and configures appropriate charging parameters autonomously
2Device complexity
If a single charging device is used to reduce construction costs, then system complexity decreases, but the ability to serve multiple vehicles simultaneously is limited
Solution Approach 1:
The charging device dynamically adjusts its operating parameters based on real-time conditions, including power availability, vehicle requirements, and charging status. This dynamic adaptation enables a single device to efficiently manage multiple vehicles with different power demands
Solution Approach 2:
The system changes operational parameters such as power transmission level, charging current, and communication protocols to optimize performance for different vehicle types and charging scenarios, allowing one device to serve multiple purposes
