Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the mobile device is designed to be portable, then the device size is reduced, but the installation space for input and output components is limited
Solution Approach 1:
The device is divided into a main body and a detachable expansion module. The expansion module contains additional input and output components that can be attached when needed, allowing the base device to remain small and portable while providing extra functionality when required.
Solution Approach 2:
The expansion module attaches to the mobile device in a direction perpendicular to the main body surfaces, utilizing three-dimensional space rather than expanding the footprint area. This allows additional components to be added without increasing the device's planar dimensions.
2Weight of moving object
If the mobile device is made compact, then portability is improved, but the functionality and user interface options are restricted
Solution Approach 1:
The expansion module provides multiple functions including additional input devices, output devices, and user interface options. This single module can serve various purposes depending on user needs, enhancing the versatility of the compact mobile device without requiring multiple separate add-on devices.
Solution Approach 2:
By separating the expansion functionality into a detachable module, the system allows users to select and attach only the functions they need, providing adaptability and versatility while maintaining a compact base device.
3Adaptability or versatility
If an expansion module is added to the mobile device, then functionality is enhanced, but the device complexity increases
Solution Approach 1:
The expansion module is designed as a self-contained unit with integrated alignment mechanisms and connection interfaces. This modular approach isolates complexity within the module itself while keeping the main device structure simple and unchanged.
Solution Approach 2:
An alignment mechanism acts as an intermediary between the expansion module and the main device body, facilitating easy attachment and detachment. This intermediary component simplifies the connection process and reduces the complexity of precise alignment requirements.
4Ease of manufacture
If the expansion module is detachable, then ease of installation is improved, but the connection stability may be reduced
Solution Approach 1:
The connection between the expansion module and main device utilizes magnetic attraction instead of purely mechanical fastening. This magnetic connection provides stable attachment while maintaining ease of installation through simple attachment and detachment actions.
Solution Approach 2:
The alignment mechanism serves as an intermediary that ensures proper positioning and stable connection during attachment. It facilitates both the ease of installation and connection stability by mediating between the expansion module and main device body.
