Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the smart ring uses a fixed internal power source, then the device structure is simple, but the ring must be removed for charging which reduces convenience
Solution Approach 1:
The power source is divided into two separate components: a fixed internal power source integrated into the ring and a removable external power source that can be detached for independent charging. This segmentation allows the ring to maintain simplicity while enabling convenient charging without removal.
Solution Approach 2:
A removable power source acts as an intermediary between the ring and charging infrastructure. This intermediary component can be detached, charged separately, and reattached, solving the contradiction between structural simplicity and charging convenience.
2Adaptability or versatility
If the smart ring includes multiple components for sensing and communication, then functionality is enhanced, but the device requires more energy which reduces battery life
Solution Approach 1:
The system dynamically adjusts power distribution based on active components and usage patterns. The removable power source can be connected when enhanced functionality is needed, and the system optimizes energy consumption based on the current configuration of active components.
Solution Approach 2:
The power source configuration can be changed by attaching or detaching the removable power source. This parameter change allows the system to adapt between different operational states: high-power mode with both power sources for enhanced functionality, and energy-saving mode with only the internal power source for extended duration.
3Adaptability or versatility
If the smart ring uses a single integrated power source, then the device structure is simple, but there is no flexibility in power capacity configurations
Solution Approach 1:
The power source system is segmented into internal and external components, allowing different capacity configurations. The removable power source can be exchanged for different capacity versions, providing flexibility without complicating the integrated ring structure.
Solution Approach 2:
The removable power source serves multiple functions: it extends battery capacity, provides alternative charging methods, and can be exchanged for different capacity versions. This universal component adds flexibility while maintaining a simple integrated ring design.
