Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional wireless charging device is provided for wireless charging, then wireless charging function is achieved, but device thickness increases and appearance is affected
Solution Approach 1:
The patent merges the wireless charging coil structure with the touch sensor structure, allowing the touch sensor to serve dual purposes: touch detection and wireless charging. The touch chip controls the touch sensor to form either a touch matrix or a receiving/transmitting coil, eliminating the need for separate wireless charging devices and reducing device thickness
Solution Approach 2:
The touch sensor is designed with multi-functionality, capable of operating in two modes: touch control mode (forming touch matrix) and wireless charging mode (forming receiving or transmitting coil). The control switch enables flexible switching between these modes, allowing one component to perform multiple functions and avoid increasing device thickness
2Adaptability or versatility
If an additional wireless charging device is provided, then wireless charging capability is enabled, but device appearance is degraded
Solution Approach 1:
The wireless charging coil is merged with the touch sensor structure, using the same conductive electrode layers to form both touch detection patterns and charging coils. This integration eliminates the need for additional external charging devices, maintaining the device's original appearance without protrusions or additional components
Solution Approach 2:
The touch sensor serves as a universal component that can function as either a touch matrix or a wireless charging coil based on control switch configuration. This multi-functionality allows the device to maintain its original appearance while enabling wireless charging capability through the same structural element

AI summary
A touch screen, an electronic device, a wireless charging method and a wireless charging system are provided, to overcome the defect in the conventional technology that an additional wireless charging device needs to be provided for an electronic device to wirelessly charging the electronic device. The touch screen is applied to the electronic device, and includes a touch sensor and a touch chip, where the touch sensor is electrically connected to the touch chip. In a case that the touch screen is used for wireless charging, the touch chip controls the touch sensor to form a receiving coil or a transmitting coil.
