Solution Overview

Problem

Existing electronic eyewear devices, such as smart glasses, face challenges in efficiently powering and managing the voltage for multiple electronic components, particularly due to the limitations of wiring through hinges which can be space-constrained and inefficient.

Innovation Solution

The implementation of a voltage controller in the frame that generates dynamic analog control signals to control voltage regulators in the temple, allowing for localized power management and efficient power distribution to each electronic component without relying on large wires across the hinge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wiring is extended through hinges to supply power to multiple loads in the temple, then electronic components can be connected and powered, but the wiring becomes space-constrained and power loss increases

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidpower loss
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent divides the power supply system into multiple independent voltage regulators, with each regulator dedicated to a specific electronic component. This segmentation eliminates the need for long wiring runs through hinges, as each component receives power locally from its dedicated regulator, thereby reducing power loss while maintaining reliable power supply.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local power management by placing voltage regulators close to the electronic components they serve within the temple. This local quality approach ensures that each component receives power from a nearby source rather than through constrained hinge wiring, reducing power loss and improving overall system reliability.

Inventive Principle:
Principle #3Local quality

2Power

If large wires are used across the hinge to supply power, then sufficient power can be delivered to components, but the device complexity and space constraints are worsened

Engineering Contradiction:
Improvepower delivery capabilityVSAvoidwiring complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The power delivery function is segmented into multiple low-power voltage regulators distributed throughout the temple, each serving a specific component. This eliminates the need for complex large-gauge wiring through the hinge, as each regulator delivers sufficient power locally to its designated component with simple, short connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The voltage regulators act as intermediary devices between the power source and electronic components. Each regulator receives power input and converts it to the appropriate voltage level for its specific component, eliminating the need for direct large-wire connections across the hinge while maintaining adequate power delivery capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple voltage rails are provided to different electronic components, then each component receives appropriate voltage, but power management becomes less efficient

Engineering Contradiction:
Improvevoltage compatibilityVSAvoidpower efficiency
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The power management system is segmented into multiple independent voltage regulators, each optimized for its specific component's voltage requirements. This segmentation enables precise voltage control for each component while maintaining overall power efficiency, as each regulator operates independently without the inefficiencies of centralized power distribution.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each electronic component receives power from a locally-situated voltage regulator that is specifically configured for that component's voltage requirements. This local quality approach ensures optimal voltage matching and power efficiency for each component, eliminating the power losses associated with centralized voltage distribution through constrained wiring.

Inventive Principle:
Principle #3Local quality

AI summary

Eyewear including a voltage controller in the frame that generates dynamic analog control signals to control voltage regulators in the temple. The voltage regulators include a voltage rail for each electronic component in the temple. A separate analog control loop is coupled to each voltage regulator and receives the respective analog control signal. Each voltage regulator generates a rail voltage on the respective voltage rail that is controlled by the respective analog control signal. The analog control loop configures the respective voltage regulator as a voltage follower regulator such that the respective rail voltage follows a voltage of the analog control signal. A power source, such as a battery, is included in the temple and provides the operating power to each electronic component, and power is not communicated across a hinge to the temple electronic components.
