Movable Battery Nudge Notification via Mass Shifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notification mechanisms in mobile devices, such as rotational and magnetic field vibrators, are insufficient for providing distinguishable notifications due to their small internal mass and limited ability to shift the center of mass, leading to vibrations that may not be readily noticeable, especially in environments like purses or bags.
Innovation Solution
A mobile device design that incorporates a movable battery within a sliding mount, allowing the battery to translate along a bay, thereby shifting the center of mass and generating a more noticeable 'nudge' effect through potential energy conversion, such as using springs or compressed gas, to provide quiet yet forceful notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rotational or magnetic field vibrators are used for notification, then the device structure is simple, but the notification effectiveness is insufficient due to small internal mass and limited center of mass shifting
Solution Approach 1:
The battery is designed to be movable rather than fixed, allowing it to translate along a bay within the device. This dynamic configuration enables the battery mass to shift position in response to notifications, creating a noticeable center of mass displacement that enhances notification effectiveness without requiring additional heavy components.
Solution Approach 2:
The battery serves dual functions: it provides power to the device and acts as a notification mechanism through its ability to move. By making the battery movable within a bay, it becomes a multi-functional component that eliminates the need for separate vibration motors or notification mechanisms, thereby increasing internal mass utilization while maintaining structural simplicity.
2Reliability
If a movable battery system is implemented to shift center of mass, then notification effectiveness improves, but device complexity increases due to additional translation mechanism
Solution Approach 1:
The translation mechanism is integrated into the battery assembly design rather than being a separate added component. The battery is designed with movable mounting that allows it to translate along a bay, combining the notification function with the existing power system. This approach minimizes additional complexity by making the battery itself the notification actuator.
Solution Approach 2:
The notification function is merged with the battery system. The battery's translational movement along the bay serves both its power provision role and its notification role. By combining these functions into a single integrated system rather than adding separate notification components, the overall device complexity is minimized while achieving effective notifications.
3Force
If springs or compressed gas are used for potential energy conversion, then notification force increases, but energy consumption and device size increase
Solution Approach 1:
The system uses the device's existing power supply to drive the battery translation mechanism, which then converts electrical energy to mechanical potential energy by positioning the battery. The battery's movement along the bay creates the notification effect through gravitational potential energy conversion, utilizing the device's own resources rather than requiring separate energy sources or complex energy storage systems.
