Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wrist device is used to monitor physical activity, then the monitoring becomes more accessible and user-friendly, but the visual brilliance and display quality may be compromised due to size constraints
Solution Approach 1:
The patent implements a multi-layer nested structure where the LED matrix is embedded within the curved body housing, with the fluorescent layer positioned between the LED matrix and the external environment. This nesting allows the display components to be compactly integrated into the wrist device while maintaining display quality through the wavelength-altering fluorescent layer.
Solution Approach 2:
The patent utilizes a fluorescent layer that changes the wavelength of light emitted by the LED matrix, transforming the optical parameters of the display. This parameter change enables enhanced visual brilliance and color quality within the constrained form factor of the wrist device, resolving the contradiction between compact size and display quality.
2Measurement precision
If additional devices are carried for detailed activity metrics, then measurement precision is improved, but device complexity and portability are worsened
Solution Approach 1:
The wrist device integrates multiple functions including physical activity monitoring, display of activity metrics, and user interaction capabilities within a single device. The curved body housing accommodates both the activity tracker circuitry and the LED matrix display system, eliminating the need for separate monitoring and display devices.
Solution Approach 2:
The patent combines the activity tracking functionality with the visual display system in a single integrated wrist device. The processing circuitry processes activity data and the LED matrix displays the metrics, merging what would traditionally require separate devices into one unified system that is both precise and portable.
3Manufacturing precision
If the LED matrix layer is manufactured with traditional techniques, then manufacturing precision may be maintained, but ease of manufacture and production efficiency are reduced
Solution Approach 1:
The patent replaces traditional mechanical assembly techniques for manufacturing the LED matrix with a printing-based approach. The electrical lead-throughs and connections are formed through printing processes, which improve manufacturing efficiency and ease of production while maintaining the required electrical connectivity and assembly precision.
