Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic holder is used to secure the device on a vertical surface, then the device is held in place, but a considerable force is needed to remove the device which may damage it
Solution Approach 1:
The magnetic holding force is made dynamic and controllable rather than static. The processing means can adjust the magnetic field strength to provide sufficient holding force during charging while enabling easy release when needed, resolving the contradiction between secure holding and easy safe removal
Solution Approach 2:
The system incorporates feedback mechanisms to detect user intent to remove the device and automatically adjusts the magnetic holding force accordingly. This feedback loop ensures the device remains securely held during normal operation but releases when the user intends to remove it, preventing damage from excessive force
2Reliability
If a bracket is used to hold the device on a vertical surface, then the device is secured in place, but the system complexity increases due to additional apparatus
Solution Approach 1:
The holding function is merged with the wireless charging device itself through integrated magnetic holding means. This eliminates the need for separate brackets or additional securing apparatus, reducing system complexity while maintaining secure device positioning on vertical surfaces
Solution Approach 2:
The wireless charging device is given multiple functions: it provides wireless charging and simultaneously provides magnetic holding capability. This multi-functionality eliminates the need for separate holding apparatus, reducing overall system complexity while maintaining device security
3Reliability
If manual securing is required for vertical surface charging, then the device can be held in place, but the ease of operation decreases due to manual intervention
Solution Approach 1:
The magnetic holding means automatically secures the device without requiring manual intervention. The processing means detects when the device is placed on the charging surface and automatically activates the magnetic field to hold it in place, making the system self-serving and improving ease of operation

AI summary
A wirelessly chargeable device, such as a smartphone, and a wireless-charging device are provided. The wirelessly chargeable device and the wireless-charging device comprise holding means for generating an attractive force between the wirelessly chargeable device and a charging surface of the wireless-charging device, so as to prevent displacement of the wirelessly chargeable device when placed on the charging surface, and processing means operative to release the wirelessly chargeable device from the charging surface in response to determining that a user intends to remove the wirelessly chargeable device from the charging surface. Advantageously, the wirelessly chargeable device may to be placed on a charging surface which is substantially vertical when in operation, effectively eliminating the need for manually securing the wirelessly chargeable device in order to prevent the wirelessly chargeable device from falling.
