Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional wired charger is used for portable computing devices, then charging reliability is ensured, but device mobility and ease of operation are reduced
Solution Approach 1:
The patent replaces the mechanical wired connection system with an inductive or magnetic resonance wireless charging system. The keyboard base incorporates a wireless charging coil that generates an electromagnetic field to transfer power to the tablet portion, eliminating the need for physical plug connections while maintaining charging functionality and improving device mobility.
2Adaptability or versatility
If a keyboard base is designed for single-sided docking, then device complexity is reduced, but adaptability and versatility are limited
Solution Approach 1:
The keyboard base is designed with dual-sided docking capability, allowing the tablet portion to be docked on either the front side or back side of the base. Both sides are equipped with identical wireless charging coils and USB Type-C connectors, enabling the base to function as a keyboard, trackpad, or charging station regardless of docking orientation, thereby achieving multi-functionality without significantly increasing structural complexity.
3Ease of operation
If wireless charging functionality is added to the keyboard base, then charging convenience is improved, but device complexity increases
Solution Approach 1:
The patent merges the wireless charging coil with the keyboard base structure, integrating the charging functionality into the existing base design. The coil is embedded within the base housing, sharing the same physical space and structural framework, which minimizes additional component count and reduces overall device complexity while still providing convenient wireless charging.
4Ease of operation
If USB Type-C connectors are implemented for reversible charging, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The keyboard base is designed with symmetrical positioning of USB Type-C connectors on both the front and back sides, creating equipotential docking conditions. The connectors are positioned at identical locations relative to the base edges, ensuring consistent alignment and electrical contact regardless of which side the tablet is docked on, thereby simplifying manufacturing tolerance requirements.
