Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a commercially available exchangeable rechargeable battery pack is used as an energy source for wireless charging, then convenience and availability of charging options are improved, but device complexity increases due to the need for an adapter with both electromechanical and wireless interfaces
Solution Approach 1:
The adapter serves as an intermediary device that bridges the battery pack and the wireless charging receiver. It contains an electromechanical interface to connect to the battery pack and a wireless interface to transmit energy to the receiver, thereby enabling charging without requiring modifications to the original battery pack or receiver devices.
2Adaptability or versatility
If an adapter with electromechanical interface and wireless interface is used, then wireless charging capability is enabled, but manufacturing cost increases
Solution Approach 1:
The adapter is designed as a universal charging solution that can work with different battery packs and wireless charging receivers. By consolidating both electromechanical and wireless interfaces into a single device, it eliminates the need for separate charging devices, thereby reducing overall system cost and manufacturing complexity.
3Length of moving object
If the adapter height extension is limited to less than twice the interface height, then compactness and portability are improved, but internal space for components is reduced
Solution Approach 1:
The adapter employs a compact, flat design that minimizes height extension while maximizing internal space utilization. By arranging components in a two-dimensional layout rather than extending vertically, the adapter achieves portability while accommodating necessary components such as the electromechanical interface, wireless coil, and circuitry.
