Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless charger is designed to charge only one electronic device, then the charging function is simple and reliable, but the device cannot charge different types of devices simultaneously
Solution Approach 1:
The wireless charging device is divided into multiple independent charging modules: a charging base for earbuds, a charging bracket for smartphones, and a charging cantilever for smartwatches. Each module can independently charge a specific device type, allowing simultaneous charging of multiple devices without requiring a single complex charging surface.
Solution Approach 2:
The charging bracket and charging cantilever are designed with rotatable connections to the charging base, allowing them to be folded or unfolded. This dynamic structure enables the device to adapt between a compact folded state for portability and an unfolded state that provides multiple charging positions for different device types.
2Adaptability or versatility
If the wireless charging device is designed with multiple charging positions, then it can charge multiple devices simultaneously, but the device size increases
Solution Approach 1:
The charging bracket and charging cantilever are designed to nest together when folded, with the cantilever positioned within or adjacent to the bracket structure. This nesting arrangement allows multiple charging components to occupy minimal space when not in use, reducing the overall device volume while maintaining multi-device charging capability when unfolded.
3Ease of operation
If the charging components are made rotatable, then the device offers flexible positioning for different devices, but the mechanical structure becomes more complex
Solution Approach 1:
The rotatable connection mechanism integrates the charging bracket and charging cantilever directly into the charging base structure, combining multiple functions (support, rotation, positioning) into unified joint designs. This merging approach reduces the number of separate mechanical components compared to using distinct mounting mechanisms for each charging element.

AI summary
A wireless charging device is provided, including a charging base, a charging bracket and a charging cantilever. The charging bracket is rotatably connected to the charging base, and when the charging bracket is unfolded with respect to the charging base, the charging bracket couples with the charging base to position a second product. The charging cantilever is rotatably connected to the charging bracket, and the rotation axis of the charging bracket is parallel to that of the charging cantilever. The wireless charging device is versatile and flexible due to its three forms. In the first form, the wireless charging device is easy to carry and can charge the second product; in the second form, at least one of the first product and the second product can be charged; in the third form, at least one of the first product, the second product and the third product can be charged.
