Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated parking systems are used to transport vehicles to various spots, then vehicle parking efficiency is improved, but automating vehicle charging becomes difficult due to varying charging port locations on different vehicles
Solution Approach 1:
The charging adapter is designed with a universal receiver that can accommodate multiple charging port types and locations. The adapter includes a connector that can engage with different vehicle charging ports and a receiver that receives various plunger configurations, allowing the same automated charging system to work with different vehicle models and port locations.
Solution Approach 2:
The charging adapter serves as an intermediary device between the automated charging system and the vehicle charging port. It includes a connector that interfaces with the vehicle port and a receiver that interfaces with the automated plunger, mediating the connection between systems with different interfaces and enabling automated charging despite port location variations.
2Adaptability or versatility
If charging port locations vary on different vehicles, then vehicle compatibility is improved, but automation of charging process deteriorates due to difficulty in locating and engaging ports
Solution Approach 1:
The system employs dynamic positioning and adjustment mechanisms. The plunger can be positioned and oriented dynamically to match the specific charging port location and configuration. The adapter and plunger include adjustable components that can adapt their position and orientation to engage with charging ports at various locations on different vehicle models.
Solution Approach 2:
The system changes geometric parameters such as position, orientation, and configuration of the adapter and plunger components to match different charging port locations. The receiver cavity dimensions, insertion axis orientation, and electrical contact positions can be adjusted or selected based on the detected port configuration to maintain automated engagement.
3Adaptability or versatility
If a universal charging adapter design is used to accommodate different vehicles, then device complexity increases, but manufacturing precision requirements worsen due to need for precise alignment and engagement
Solution Approach 1:
The adapter and plunger designs incorporate asymmetric features that provide natural alignment and engagement. The receiver cavity, insertion axis, and electrical contacts are configured with asymmetric geometries that guide the plunger into the correct position during automated engagement, reducing the precision requirements compared to symmetric designs that would require exact alignment in multiple directions.

AI summary
A vehicle charging adapter including a connector configured to engage with a charging port of a vehicle, and a receiver coupled to the connector. The receiver includes a receiver charging surface, an indicator provided on the receiver charging surface, an inner radial wall extending from the receiver charging surface and defining a receiver cavity extending along an insertion axis, and one or more receiver electrical contacts provided on the inner radial wall within the receiver cavity. The one or more receiver electrical contacts are electrically connected to the connector.
