Electronic Frame Magnetic Hinge Sensing for Standby Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic frames, such as glasses with electronic components, consume energy even when not in use, leading to unnecessary power consumption.
Innovation Solution
Incorporation of a magnetic or electric field sensor and emitter in the frame's hinge mechanism to detect the open or closed position of the arms, allowing the power supply to be switched to standby mode when the frame is not being worn, and enabling intelligent energy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the electronic frame operates continuously to provide corrective lens functions, then the optical performance is maintained, but the energy consumption increases unnecessarily when the frame is not being worn
Solution Approach 1:
The magnetic sensor detects the closed position of the arms in advance to trigger the standby mode before the user actually stops using the glasses, allowing the system to proactively reduce energy consumption while maintaining readiness to resume operation
Solution Approach 2:
The system continuously monitors the arm position through the magnetic sensor and provides feedback to the control circuit, which automatically adjusts the power supply state based on whether the arms are open or closed, creating a closed-loop control system that optimizes energy usage
2Volume of moving object
If the frame arms are closed to indicate non-use, then the frame structure is compact, but the user cannot easily access or adjust the electronic components
Solution Approach 1:
The system automatically detects when the user opens the arms and activates the electronic components without requiring any manual intervention or button pressing from the user, making the device self-activating and eliminating the need for users to manually access or adjust electronic components
3Use of energy by moving object
If a magnetic sensor and emitter are added to detect arm position, then energy management is improved, but the device complexity increases
Solution Approach 1:
The magnetic emitter and sensor act as intermediary detection elements that passively detect arm position through magnetic field changes, allowing the system to determine usage state without requiring complex mechanical switches, buttons, or active user input mechanisms
Solution Approach 2:
The invention replaces potential mechanical detection methods (such as mechanical switches or contact-based sensors) with a magnetic field-based detection system, which reduces mechanical wear, simplifies the physical structure, and enables contactless detection of arm position
