Problem
The challenge is to integrate a wireless power transmission module into a laptop computer equipped with an optical disk drive, as existing solutions face limitations due to the laptop's size and complexity, making it difficult to implement wireless charging functionality effectively.
Innovation Solution
An optical disk drive is designed to accommodate a wireless power transmission module with a primary coil and transmitting circuit, utilizing a controller to supply power only when the module is seated on the tray, and employing a spindle motor and optical pickup to determine the module's presence, allowing for wireless charging of smart terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless power transmission module is integrated into a laptop computer, then wireless charging convenience is improved, but device complexity increases
Solution Approach 1:
The optical disk drive tray is repurposed to serve dual functions: its original function of holding optical disks and a new function of accommodating the wireless power transmission module. The controller is enhanced to recognize the module's presence and switch between optical disk driving modes and wireless power transmission modes, making the same hardware components serve multiple purposes and avoiding additional dedicated structures for wireless charging.
Solution Approach 2:
The wireless power transmission module is merged with the optical disk drive assembly, specifically utilizing the tray mechanism and controller. The module shares physical space and control resources with the optical drive functionality, combining what would traditionally be separate systems into a unified integrated structure that reduces overall device complexity.
2Adaptability or versatility
If the optical disk drive is used to accommodate the wireless power transmission module, then the need for external power sources is reduced, but the optical disk drive functionality may be affected
Solution Approach 1:
The controller dynamically adapts its behavior based on what is detected on the tray. When a wireless power transmission module is detected, the controller switches to power transmission mode, supplying power to the module's primary coil. When an optical disk is detected, it switches to optical drive mode. This dynamic switching allows the same hardware to support multiple functions without permanent structural modifications.
Solution Approach 2:
The system changes operational parameters based on the detected object. The controller monitors tray state and object presence, then adjusts power supply parameters accordingly - either providing power to the wireless transmission module or to the optical drive mechanisms, or neither when the tray is empty. This parameter-based control enables flexible functionality without adding permanent complexity.
