Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wireless charging bases use built-in induction coils coiled on a particular plane, then the charging structure is simple, but the charged portable electronic device must be set at a specific location precisely which reduces ease of operation
Solution Approach 1:
The patent transitions from planar induction coils to a three-dimensional bowl-shaped charging chamber. The charging coil is configured to extend along the circumferential direction of the bowl shape, creating a volumetric charging field rather than a planar one. This dimensional change allows electronic devices to be charged at multiple orientations and positions within the bowl, eliminating the need for precise placement on a specific plane.
2Adaptability or versatility
If multiple induction coils are incorporated to improve charging flexibility, then charging coverage is increased, but power consumption increases which worsens energy efficiency
Solution Approach 1:
The patent merges multiple induction coils into a unified bowl-shaped charging chamber structure. Instead of using separate planar coils that would require multiple independent power sources, the coils are integrated along the circumferential direction of the bowl, sharing a common magnetic core and power supply. This consolidation achieves versatile charging coverage while optimizing power utilization efficiency.
Solution Approach 2:
The bowl-shaped charging chamber serves multiple functions: it provides a unified charging field for various device orientations, acts as a magnetic shielding structure, and enables both horizontal and vertical charging configurations. This multi-functionality replaces what would otherwise require multiple separate charging systems, reducing overall power consumption while maintaining adaptability.
3Ease of operation
If sensing devices are designed with integrated equipment and power source connected by wire connection, then the sensing device structure is stable, but it requires tedious work when changing or relocating sensing units which reduces ease of operation
Solution Approach 1:
The sensing device system is segmented into modular components: a portable sensing unit and a separate power supply unit. The sensing unit can be easily detached and relocated, while the power supply remains stationary and connected to mains electricity. This segmentation enables flexible deployment and reconfiguration of sensing devices without the complexity of redesigning integrated systems.
Solution Approach 2:
A wireless charging module acts as an intermediary between the portable sensing unit and the stationary power supply. The module includes a bowl-shaped charging chamber with induction coils that wirelessly transmit power to the sensing unit when placed within the chamber. This intermediary enables contactless power transfer, eliminating the need for physical wire connections while maintaining stable power supply.

AI summary
The present application provides a wireless charging module and a modularized sensing device therewith. A first charging unit is disposed around the inside of the wireless charging module for wirelessly charging a sensing module. Without introducing a transmission line as an electricity transmitting medium, the sensing module can be directly disposed inside and charged by the wireless charging module, which improves flexibility of implementation. Further, since the first charging unit is configured to surround the inside of the wireless charging module shaped as a bowl structure, the sensing module can be simply disposed into the bowl structure and wirelessly charged by the surrounding first charging units, which saves the inconvenience of setting the sensing module to a specific location or area for stable wireless charging and increases effective charging angles.
