Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate wireless charging antenna is installed in the mobile device, then wireless charging function is achieved, but the device thickness increases
Solution Approach 1:
The patent merges the wireless charging antenna with the display substrate by integrating the power receiving coil directly onto the display substrate. This combination eliminates the need for separate antenna components and reduces overall device thickness while maintaining wireless charging functionality.
Solution Approach 2:
The display substrate is designed to serve multiple functions: it acts as both the display structure and the wireless charging antenna substrate. The power receiving coil is integrated onto the same substrate that supports display components, making the substrate universal for both display and wireless charging purposes.
2Reliability
If wireless charging components are added to the device, then wireless charging capability is provided, but internal space is occupied
Solution Approach 1:
The wireless charging components (power receiving coil) are merged with the display substrate structure. By using the display substrate as the mounting platform for the antenna, the patent eliminates the need for separate internal space allocation for wireless charging components.
Solution Approach 2:
The power receiving coil is nested within the display substrate structure. The antenna is embedded or integrated into the existing display layers, allowing wireless charging functionality to be housed within the same volume that already contains display components.
