Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional power sources with separate cables and adapters are used, then charging capability is provided, but device complexity and portability are reduced
Solution Approach 1:
The patent combines multiple charging cables with different connectors (USB-C, Lightning, Micro-USB) and power adapters into a single integrated portable power charger unit. This merging eliminates the need to carry separate cables and adapters, directly resolving the technical contradiction by improving portability while maintaining comprehensive charging capability across multiple device types.
Solution Approach 2:
The portable power charger is designed with universal compatibility to charge multiple types of electronic devices simultaneously through integrated multi-port output capabilities. The single device performs multiple functions (charging smartphones, tablets, laptops, and other electronics) that previously required separate dedicated chargers, thereby reducing overall system complexity while maintaining broad charging functionality.
2Use of energy by moving object
If a single power source charges multiple devices sequentially, then power is conserved, but charging time increases
Solution Approach 1:
The portable power charger enables continuous simultaneous charging of multiple devices through dedicated charging ports that operate in parallel. Instead of sequential charging where one device must wait for another, the system provides continuous useful action by charging multiple devices at the same time, thereby reducing total charging time while maintaining efficient power distribution across all connected devices.
3Weight of moving object
If portable power chargers are designed for compact size, then portability is improved, but charging capacity is reduced
Solution Approach 1:
The patent employs a nested design where multiple charging cables with different connector types are stored within the body of the portable power charger itself. This nesting approach maximizes the utilization of internal space, allowing the charger to maintain a compact, portable form factor while still providing access to multiple cable types and sufficient battery capacity to charge multiple devices simultaneously.

AI summary
A portable power charger is provided for charging a small appliance or an electronic device from a rechargeable battery internally disposed within the charger. An attachment system is also provided for connecting the electronic device to the portable charger and maintaining the connection during charging, whether by wireless or direct charging means. The attachment system ensures that respective wireless transmission components in the portable charger and the electronic device, where available, are properly aligned for optimal and efficient wireless charging. The alignment system can comprise structural feature formed in the charger housing, such as grooves or projections formed on the charger housing to physically attach the portable charger to the small appliance or the electronic device, whereby the connection can be maintained during the exchange of a charge from the portable power charger to the small appliance or electronic device.
