Electronic Glasses Temple Folding Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart glasses have limited battery life, typically lasting about 16 hours, and often run out of battery quickly when used for photography or map information display, deterring consumer adoption due to portability and power concerns.
Innovation Solution
The electronic glasses incorporate a Hall sensor and magnet within the audio input/output device, generating signals when the temples are folded or unfolded, allowing the device to automatically turn off or on, thereby conserving power and extending battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical buttons are used to turn on and off the device, then the device is easy to operate, but the user may forget to turn it off causing undue power consumption
Solution Approach 1:
The device automatically detects when the temples are folded together and turns off the electronic components without requiring user intervention. The Hall sensor detects the magnetic field change when temples are folded, triggering automatic shutdown to prevent power waste from forgotten manual shutdowns.
Solution Approach 2:
The system uses Hall sensors to continuously monitor the spatial relationship between temples and provides feedback to the control unit. When the temples are detected to be folded together, the system automatically initiates shutdown sequence, creating a closed-loop control system that responds to user actions.
2Duration of action of moving object
If the battery capacity is increased to extend usage time, then the battery life is prolonged, but the device size and weight increase
Solution Approach 1:
The device implements periodic operation by automatically shutting down when temples are folded and resuming when unfolded. This intermittent operation pattern significantly reduces average power consumption, allowing smaller battery capacity while maintaining extended effective usage time between charging cycles.
Solution Approach 2:
The system dynamically changes operational parameters by switching between active and standby states based on temple configuration. When folded, the device transitions to low-power mode, effectively extending battery life without increasing physical battery capacity or device weight.
3Adaptability or versatility
If the device operates continuously to provide map information display and photography, then the functionality is maintained, but the battery runs out significantly faster
Solution Approach 1:
The device automatically manages its own power consumption by detecting temple folding state and shutting down non-essential functions. This self-service mechanism ensures full functionality when needed while automatically conserving energy during storage or non-use periods.
Solution Approach 2:
The system dynamically adjusts its operational state based on real-time detection of temple configuration. Full functionality is available when temples are unfolded for use, while automatic shutdown occurs when folded for storage, creating adaptive power management that extends battery life without compromising usability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively prolongs the battery life of electronic glasses by automatically turning off the device when folded, reducing unnecessary power consumption and enhancing user experience through extended usage time.
Implementation Method 1
The Hall sensor provides a first signal for the electronic device when the first temple and/or the second temple are folded to make the Hall sensor and the audio I/O device close to each other
Data Source
AI summary
An electronic glasses includes a lens frame, a first temple, a second temple, an electronic device and an audio I/O device. The Hall sensor is disposed at one of the lens frame, the first temple, and the second temple. The audio I/O device is disposed at another of the lens frame, the first temple and the second temple, and provided with a magnetic element. The Hall sensor provides a first signal for the electronic device when the first temple and/or the second temple are folded to make the Hall sensor and the audio I/O device close to each other, and the Hall sensor provides a second signal for the electronic device when the first temple or the second temple are unfolded to make the Hall sensor and the audio I/O device be away from each other.
