Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If conventional wearable devices use displays to show biometric data, then users can review sensor data, but users must interrupt or pause their workout to view the data

Engineering Contradiction:

Improveaccess to biometric dataVSAvoidworkout continuity

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The patent replaces the mechanical display system (screens, buttons, touch interfaces) with an optical signaling system using LEDs. This substitution allows biometric data to be communicated through light patterns (colors, frequencies, pulsing) that users can perceive peripherally during exercise, eliminating the need to stop workouts to check displays.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces LED lights as an intermediary medium between the sensor data collection system and the user. Instead of directly displaying data on screens that require user attention, the system uses optical signals that can be perceived indirectly, allowing users to monitor biometric information without breaking their workout flow.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If conventional wearable devices require user interaction to access data, then users can review detailed information, but users cannot conveniently access data during physical activities

Engineering Contradiction:

Improvebiometric data accessVSAvoiddata accessibility during exercise

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent implements a self-service system where the wearable device automatically monitors, processes, and communicates biometric data through LED signals without requiring user initiation or interaction. The system continuously provides feedback based on pre-set thresholds, allowing users to passively receive information about their performance metrics during exercise.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent establishes a continuous feedback loop where sensor data is constantly monitored against target thresholds, and LED signals provide real-time feedback to users. This automated feedback mechanism eliminates the need for users to manually query or interact with the device to obtain biometric information.

Inventive Principle:

Principle #23Feedback

3Loss of information

If head-worn devices use overhead displays to show sensor data, then users can see biometric information, but the display obstructs the user's view

Engineering Contradiction:

Improvebiometric data visibilityVSAvoidview obstruction

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical overhead display system with an optical signaling system using LEDs positioned on the head-worn device. This substitution allows biometric data to be communicated through light patterns that users can perceive through peripheral or indirect vision, eliminating the visual obstruction caused by physical displays in the user's field of view.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Methods and systems of coordinating display of biometric data at a head-worn wearable device based on sensor data from a wrist-wearable device are disclosed. A method includes receiving an indication that a user of a head-worn wearable device is performing a physical activity. The head-worn wearable device includes a light-emitting diode visible to the user while wearing the head-worn wearable device and is in communication with a wrist-wearable device worn by the user. The wrist-wearable device is configured to sense biometric data for the user during the physical activity. The method includes, after receiving the indication and while the user is performing the activity, in accordance with a determination that the biometric data satisfies a physiological-based threshold indicating that information about the biometric data would assist the user in performing the physical activity, causing the head-worn wearable device to present, via the light-emitting diode, the information about the biometric data.
