Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional wearable devices display sensor data using a heads-up display or overhead display, then the user can review biometric data, but the display obstructs the user's view and distracts the user from physical activity
Solution Approach 1:
The patent replaces the mechanical display system (heads-up display or overhead display) with an optical signaling system using LEDs. Instead of using a display screen that physically obstructs the user's view, the invention uses light-based indicators that provide biometric feedback without blocking the user's forward vision, thus eliminating the harmful effect of view obstruction while maintaining data accessibility.
Solution Approach 2:
The patent introduces an intermediary optical signaling system (LEDs) that mediates between the biometric data collection and the user's need for unobstructed vision. The LEDs serve as an intermediate communication channel that conveys performance feedback without requiring the user to look at a display screen, thus resolving the contradiction between information delivery and view obstruction.
2Ease of operation
If conventional wearable devices require user interaction to access sensor data, then device functionality is maintained, but the user's physical activity is interrupted and productivity is reduced
Solution Approach 1:
The patent implements a self-service information delivery system where biometric feedback is automatically provided to the user through LED indicators without requiring any user initiation or interaction. The system autonomously monitors performance metrics and communicates results, eliminating the need for users to pause their activity to check devices and thereby maintaining physical activity continuity.
Solution Approach 2:
The patent uses periodic optical signaling through LEDs to deliver biometric feedback at appropriate intervals during physical activity. This periodic delivery mechanism provides continuous performance monitoring information without requiring constant user interaction, allowing users to maintain their physical activity while receiving periodic performance updates.
3Loss of information
If head-worn wearable device uses illumination source to display sensor data, then real-time monitoring is enabled, but the illumination may distract the user from physical activity
Solution Approach 1:
The patent applies local quality by positioning LEDs in specific locations on the head-worn device where they provide biometric feedback without creating distracting visual effects. The illumination is localized and directed in a way that communicates performance information clearly while minimizing peripheral visual distraction, allowing real-time monitoring without compromising focus on physical activity.

AI summary
Methods and systems of coordinating display of performance-based indicators at a head-worn wearable device based on sensor data are disclosed. An example method includes receiving sensor data from one or more sensors while a user wearing a head-wearable device is performing a physical activity. The sensor data includes, at least, performance-based data and physiological-based data, and the head-wearable device includes one or more light-emitting diodes. The method includes determining whether the sensor satisfies one or more activity-based thresholds. The method includes, in accordance with a determination that the user-defined performance threshold is not satisfied, causing the head-wearable device to illuminate a light-emitting diode (LED) of the one or more LEDs with first LED characteristics. The method includes, in accordance with a determination that the user-defined biometric threshold is not satisfied, causing the head-wearable device to illuminate the LED of the one or more LEDs with second LED characteristics.
