Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed charging module is used, then the charging location is fixed and easy to manage, but the user must search for available chargers in complex parking lots which wastes time
Solution Approach 1:
The charging module is designed to be movable rather than fixed, allowing it to dynamically relocate itself to different parking positions. The module includes wheels or other movement mechanisms that enable it to autonomously navigate to where vehicles need charging, eliminating the need for users to search for fixed charging points.
Solution Approach 2:
The charging module autonomously performs the function of locating and approaching vehicles that need charging. It uses sensors to detect vehicles and automatically moves to connect with them, making the system self-sufficient in finding its own users without requiring user effort to locate the charger.
2Adaptability or versatility
If a movable charging module is used, then the user can charge at any parking location, but the system becomes more complex
Solution Approach 1:
The charging module is designed as a universal unit that can serve multiple functions: it can move to different locations, detect various vehicles, establish electrical connections, and provide charging services. This multi-functional design allows a single module to replace multiple fixed chargers, making the system versatile without proportionally increasing complexity.
Solution Approach 2:
The charging system is divided into independent modular units that can function autonomously. Each module is a self-contained unit with its own power supply, movement capability, and vehicle interaction systems, allowing the overall system to be scalable and manageable despite its versatility.
3Productivity
If only fixed charging modules are used, then the system is simple to manage, but the charging speed is limited
Solution Approach 1:
The system combines multiple charging modules (both movable and fixed) to work together on a single vehicle when high-speed charging is needed. Multiple modules can simultaneously connect to different ports on the same vehicle, providing combined power output that achieves high-speed charging capability while maintaining manageable system complexity through modular architecture.
