Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stylus pen is detachably attached to the hinge housing using a magnet, then the attachment stability is improved, but the device complexity increases due to additional magnetic components and positioning structures
Solution Approach 1:
The patent combines the magnet and positioning structure into an integrated assembly that is embedded within the hinge housing. The magnet is positioned at a specific location on the hinge housing to attract and hold the stylus pen, while the positioning structure ensures proper alignment. This merging of components achieves stable attachment without significantly increasing overall device complexity.
Solution Approach 2:
The hinge housing serves as an intermediary structure that houses both the magnet and positioning structure. This intermediary component provides a stable platform for attaching the stylus pen while maintaining the folding functionality of the device. The hinge housing mediates between the need for stable attachment and the requirement for device simplicity.
2Ease of operation
If a charging coil is disposed between the hinge assemblies to wirelessly charge the stylus pen, then the ease of operation is improved, but the device complexity increases due to additional wireless charging components
Solution Approach 1:
The charging coil is merged with the hinge module structure, positioned between the first and second hinge assemblies. This integration allows the stylus pen to be charged wirelessly when attached to the hinge housing, providing ease of operation without requiring separate charging infrastructure. The charging coil becomes a functional part of the hinge assembly rather than an add-on component.
Solution Approach 2:
The hinge housing is designed to serve multiple functions: it provides structural support for folding, houses the magnet for stylus attachment, contains the positioning structure for alignment, and incorporates the charging coil for wireless charging. This multi-functionality improves ease of operation while minimizing the need for separate components, thereby controlling device complexity.
3Manufacturing precision
If the hinge housing includes a conductive material with a slot and non-conductive plate, then the manufacturing precision is improved for component alignment, but the ease of manufacture decreases due to more complex housing structure
Solution Approach 1:
The hinge housing incorporates a slot with a non-conductive plate at a specific location to provide precise positioning for the magnet and charging coil. This localized feature provides the necessary manufacturing precision for component alignment only where needed, rather than requiring the entire housing structure to be highly complex. The conductive material with the slot creates a defined geometric reference that facilitates accurate placement of internal components.
