Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a display device is designed to be lightweight and compact for wearable use, then comfort and portability are improved, but power supply capacity and display functionality are reduced
Solution Approach 1:
The power supply is divided into a main battery and a detachable external battery. The main battery provides power for basic operations, while the external battery can be attached when extended power is needed. This segmentation allows the device to remain lightweight during normal use while providing access to greater power capacity when required.
Solution Approach 2:
The display surface extends from the top surface to the side surface of the ring portion, utilizing three-dimensional space. This allows the display area to be increased without proportionally increasing the device volume or weight, as the display wraps around the ring structure.
2Adaptability or versatility
If the display area is increased to provide more input regions, then input versatility is improved, but device size and weight are increased
Solution Approach 1:
The display surface is extended to the side surface of the ring portion, utilizing the vertical and lateral dimensions of the ring structure. This creates multiple display regions (top surface display region and side surface display region) that provide versatile input capabilities without requiring a larger overall device footprint.
Solution Approach 2:
The ring portion has a curved geometry that allows the display to wrap around it. This curved configuration provides multiple input surfaces (top and side) within a compact form factor, enabling versatile input operations while maintaining a small, wearable size.
3Adaptability or versatility
If flexible materials are used to accommodate varying finger sizes, then adaptability is improved, but structural strength and durability are reduced
Solution Approach 1:
The ring portion is made of a flexible material that can elastically deform to accommodate different finger sizes and shapes. This flexibility allows the device to adapt to various users while maintaining structural integrity through the elastic recovery of the material.
Solution Approach 2:
The ring portion has a curved, cylindrical geometry that naturally distributes mechanical stress. This curved structure, combined with flexible material, provides both adaptability to different finger sizes and sufficient structural strength to protect internal components.
