Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wall-mounted charging station is connected to the public electrical grid, then it can provide power for charging electric vehicles, but it becomes unreliable during public power supply outages
Solution Approach 1:
The patent combines the wall-mounted charging station with a buffer storage device (battery system) into a single integrated unit. This merging allows the charging station to operate independently from the public electrical grid during outages by utilizing stored energy in the buffer storage, thereby resolving the contradiction between reliability during outages and independence from the public grid.
Solution Approach 2:
The buffer storage device is charged in advance during normal operation when the public electrical grid is available. This preliminary action of storing energy beforehand enables the charging station to continue operating reliably during power supply outages without requiring real-time connection to the public grid.
2Reliability
If a communication device uses terrestrial communication networks, then it can provide internet connection, but it becomes unavailable in remote areas without terrestrial communication infrastructure
Solution Approach 1:
The communication device is designed to support multiple communication modes: terrestrial communication networks and satellite communication. This multi-functionality allows the device to adapt to different environments - using terrestrial networks when available and switching to satellite communication in remote areas, thereby resolving the contradiction between communication reliability and geographic coverage.
3Ease of manufacture
If separate devices are used for charging station, buffer storage, and communication, then each device can be optimized independently, but the system complexity and space requirements increase
Solution Approach 1:
The patent integrates the wall-mounted charging station, buffer storage device, and communication device into a single combined unit. This merging reduces system complexity by eliminating the need for separate installations and interconnections between devices, while still allowing each component to maintain its optimized design. The integrated design also reduces space requirements and simplifies installation.
