Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate chargers are used for main device and associated device, then each device can be charged independently, but user burden increases and space clutter increases
Solution Approach 1:
The patent combines the charging function for both main device and associated device into a single charger unit. The charger simultaneously charges the main device through its primary charging port and the associated device through a secondary charging port, eliminating the need for users to carry multiple separate chargers while maintaining reliable charging for both devices.
Solution Approach 2:
The charger is designed with multi-functionality to serve multiple purposes: it can charge the main device, charge the associated device, or charge both devices simultaneously. This universal charging solution replaces the need for device-specific chargers, reducing user burden and space requirements while maintaining charging reliability for all devices.
2Reliability
If multiple chargers are carried for different devices, then each device can be charged, but the number of accessories increases and space is consumed
Solution Approach 1:
The patent merges multiple charging functions into a single physical charger unit with multiple ports. This allows users to charge both the main device and associated device using one charger instead of carrying separate chargers for each device, thereby reducing the quantity of charging accessories needed while maintaining full charging capability for all devices.
3Adaptability or versatility
If separate chargers are used for each device, then charging can be performed independently, but clutter in user space increases
Solution Approach 1:
The patent combines multiple charging functions into a single charger unit that occupies minimal space. By integrating the ability to charge both main and associated devices into one unit, the patent reduces the total storage space required while maintaining charging flexibility through multiple ports and simultaneous charging capability.
