Telescopic Wireless Charging Coil Switching for Heat Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless charging in electronic devices leads to significant heating due to low conversion efficiency, causing excessive heat accumulation and poor user experience.
Innovation Solution
The system controls the on-off of first and second coils based on temperature detection, switching charging states to avoid overheating by disconnecting coils when temperatures exceed preset thresholds and using a heat dissipation apparatus to dissipate heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a camera module and a flash are disposed close to each other, then the snapshot function can be performed, but the antenna performance is deteriorated due to interference
Solution Approach 1:
A shielding structure is introduced as an intermediary element between the camera module and the antenna. This shielding structure blocks the electromagnetic interference from the camera module and flash, protecting the antenna from degradation while allowing the camera and flash to remain in their optimal positions for snapshot functionality.
Solution Approach 2:
The electronic device is segmented into distinct functional zones with the shielding structure creating a spatial separation between the interfering components (camera module, flash) and the sensitive component (antenna). This segmentation allows each component to operate independently without mutual interference.
2Productivity
If the camera module is disposed at a lower side of the display, then the snapshot function is enabled, but the appearance design is compromised due to protrusion
Solution Approach 1:
The camera module is nested within a recessed region of the housing, allowing it to be positioned at the lower side of the display for snapshot functionality while being partially or fully embedded in the housing structure. This nesting approach prevents the camera module from protruding excessively, thereby maintaining a sleek appearance design.
3Duration of action of moving object
If the battery capacity is increased, then the operation time is extended, but the housing volume is increased
Solution Approach 1:
The battery is configured to extend in the thickness direction of the housing rather than only in the planar dimensions. This dimensional change allows the battery capacity to be increased by utilizing the vertical space, thereby extending operation time without significantly increasing the overall housing volume.
