Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed charging station is installed in a building or community, then charging service is provided, but installation is prohibited due to insufficient power supply or aesthetic concerns

Engineering Contradiction:

Improvecharging service availabilityVSAvoidinstallation feasibility

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The charging system transitions from a static fixed charging station to a dynamic mobile power supplying equipment that can autonomously navigate to different charging locations. The mobile equipment includes movement capabilities and can relocate itself to serve multiple vehicles, making the charging infrastructure adaptable without permanent installation in each location.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The charging system is divided into separate functional components: a fixed charging base that remains stationary and a mobile power supplying equipment that moves independently. This segmentation allows the power supply function to be decoupled from fixed installation requirements, enabling flexible deployment without modifying building infrastructure.

Inventive Principle:

Principle #1Segmentation

2Productivity

If multiple electric vehicles are charged simultaneously at fixed charging stations, then charging service is improved, but waiting time increases due to insufficient charging stations

Engineering Contradiction:

Improvecharging service capacityVSAvoidwaiting time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The mobile power supplying equipment can dynamically relocate to serve different electric vehicles in sequence or parallel, increasing the effective charging capacity without requiring multiple fixed charging stations. This mobility allows a single unit to serve multiple vehicles, reducing waiting time through flexible resource allocation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mobile power supplying equipment autonomously navigates to charging locations and docks with vehicles without requiring manual intervention. This self-service capability enables the system to efficiently manage multiple charging tasks, reducing idle time and improving overall charging throughput.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If a mobile power supplying equipment is used, then installation constraints are reduced, but automatic docking precision must be achieved for reliable power transfer

Engineering Contradiction:

Improvedeployment flexibilityVSAvoiddocking precision

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The mobile power supplying equipment incorporates sensors and control systems that provide real-time feedback during the docking process. The system detects the position and orientation of the charging base, automatically adjusts its approach, and makes precise corrections to achieve accurate alignment and reliable electrical connection.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system replaces manual docking operations with automated control systems that use electronic sensing and actuation. Instead of mechanical alignment procedures, the system uses electronic feedback loops to control the positioning mechanisms, achieving precise docking through automated control rather than mechanical adjustment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A charging system for charging an electric vehicle includes a charging device and a mobile power supplying equipment. The charging device includes a charging base, a power receiving terminal disposed on the charging base, and a charging gun electrically connected to the power receiving terminal and configured to charge the electric vehicle. The mobile power supplying equipment includes a power module, a docking device, and a power supplying terminal disposed on the docking device and electrically connected to the power module. When the mobile power supplying equipment moves to a position within a predetermined range of the charging base, the docking device is configured to adjust the power supplying terminal to make the power supplying terminal detachably dock with the power receiving terminal, and the power module then outputs power to the charging gun for the charging gun charging the electric vehicle.
