Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed interface charging device is used, then the charging connection is stable, but the device cannot adapt to electronic devices of different dimensions
Solution Approach 1:
The patent employs elastically deformable layers that can dynamically adjust their shape and size to accommodate different electronic device dimensions. The elastic deformation capability allows the charging device to maintain reliable contact and alignment with various device sizes while preserving connection stability through the restoring force of the elastic material.
Solution Approach 2:
The charging device utilizes changes in physical parameters of the elastic layers, specifically their deformation state, to adapt to different device dimensions. By allowing the layers to elastically deform, the device can change its geometric parameters (shape, size, curvature) to match the electronic device being charged, thereby achieving both adaptability and reliable connection.
2Ease of operation
If rigid charging device structure is used, then the structural stability is high, but the comfort and adaptability in wearable applications is reduced
Solution Approach 1:
The patent employs flexible layers including elastically deformable layers and fabric layers that can conform to the body and different device shapes. These flexible structures maintain structural integrity through their material properties while providing comfort and adaptability for wearable applications, allowing the charging device to be integrated into clothing and accessories.
3Adaptability or versatility
If integrated battery design is used, then the device is compact, but the waste management and flexibility are reduced
Solution Approach 1:
The patent separates the battery from the main charging device structure, allowing the battery to be a removable component. This segmentation enables users to replace only the battery when depleted or obsolete, rather than discarding the entire charging device, thereby reducing waste while maintaining compact and flexible design.
Solution Approach 2:
The removable battery design allows for easy removal and replacement of the battery component. When a battery is depleted or obsolete, it can be discarded and replaced with a new one, while the main charging device structure is retained and reused, thereby reducing overall waste and extending the product lifecycle.
