Ergonomic Power Switch for Wearable Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable electronic devices do not fully leverage human factors and human-device interaction, resulting in limitations in comfort, safety, usability, and productivity, particularly in terms of intuitive power management.
Innovation Solution
The implementation of an ergonomic power switch that selectively closes the circuit of a wearable electronic device when a user wears it, using skin-conductive contacts or optical beams to detect the user's body, allowing for automatic powering on and off, thereby enhancing usability and avoiding the need for manual button pressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button pressing is used for power control, then device can be turned on/off, but usability is reduced and user convenience is compromised
Solution Approach 1:
The power switch automatically detects when the wearable device is being worn through body detection mechanisms (skin-conductive contacts or optical beams) and autonomously powers the device on or off without requiring manual user intervention. This self-service approach eliminates the need for manual button pressing while managing power control complexity internally
Solution Approach 2:
The patent replaces the traditional mechanical button-pressing system with a body-detection-based switching mechanism. Skin-conductive contacts detect body proximity through electrical conductivity changes, or optical beams detect body presence through light interruption, substituting the mechanical interaction with sensor-based detection to improve ease of operation
2Ease of operation
If automatic body detection is implemented, then power management becomes intuitive and convenient, but device complexity increases
Solution Approach 1:
The patent introduces intermediary detection mechanisms (skin-conductive contacts or optical beams) that mediate between the user's body and the power control system. These intermediaries translate body presence into electrical or optical signals that trigger automatic power management, providing intuitive control while managing detection complexity through established sensor technologies
Solution Approach 2:
The body detection mechanism serves multiple functions: it detects whether the device is being worn, triggers power on/off states, and can potentially serve as part of the user interface for other functions. This multi-functionality justifies the added detection complexity by providing broad operational benefits across different use scenarios
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 improves the usability of wearable electronic devices by enabling intuitive power management, ensuring the device is powered when worn and turned off when not in use, thus enhancing convenience and productivity.
Implementation Method 1
The connection event may occur in response to a portion of a body of a user being positioned between the multiple elements. The user's body may cause the connection event to occur in a number of ways. For example, the user's body may act as an electrical conductor between multiple skin-conductive contacts included in the multiple elements.
Implementation Method 2
As another example, the user's body may intercept an optical beam transmitted between the multiple elements.

AI summary
Disclosed are ergonomic power switches for wearable electronic devices. A wearable electronic device may include a circuit including a power supply, and an ergonomic power switch to selectively close the circuit. The ergonomic power switch may comprise multiple elements that are configured to cause closure of the circuit in response to a connection event. The connection event may occur in response to a portion of a user's body being positioned between the multiple elements. A process may include determining, by a controller of a wearable electronic device, that a connection event has occurred, and setting a power state of the wearable electronic device to a power-on state where power is supplied to multiple electrical components of the wearable electronic device from a power supply of the wearable electronic device.
