Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wired charging systems are used, then charging can be performed at designated stations, but the connection is prone to accidental disconnection and interruptions
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless charging system that uses electromagnetic fields for power transfer. This eliminates the physical power cord that can be accidentally disconnected, thereby improving connection stability while maintaining charging convenience through automatic coupling between the charging stand and hub apparatus.
Solution Approach 2:
The patent introduces a charging stand as an intermediary device that provides both wired and wireless charging capabilities. The stand acts as a mediator between the power source and the hub apparatus, offering a stable platform that prevents accidental disconnection while enabling flexible charging modes.
2Reliability
If users must locate designated charging stations, then charging infrastructure is established, but it becomes troublesome for users to find available stations
Solution Approach 1:
The patent enables the hub apparatus to charge itself automatically when docked at the charging stand, eliminating the need for users to actively locate and connect to charging stations. The system provides self-service charging functionality where the hub apparatus simply needs to be positioned at the stand for automatic charging initiation.
Solution Approach 2:
The charging stand is designed with universal compatibility to work with multiple hub apparatus units and can be placed in various locations (home, office, etc.), transforming a single-function stationary charger into a multi-location, multi-device charging solution that reduces the need to search for specialized charging stations.
3Productivity
If wired charging connection is used, then power transfer is established, but the connection can be accidentally broken causing charging interruption
Solution Approach 1:
The patent replaces the mechanical wired connection with a wireless electromagnetic power transfer system. This substitution eliminates the physical connection points that are susceptible to accidental disconnection, thereby ensuring charging continuity while maintaining efficient power transfer through the wireless charging interface between the stand and hub apparatus.
