Proximity-Based Removal Warning for Connectable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectable devices, such as USB memory sticks, often experience data loss when removed unexpectedly during data transfer due to the lack of effective notification methods, as visual indicators like busy lights may not be visible or clear to users.
Innovation Solution
Incorporating a proximity sensor and an indicator element, such as a sound or haptic device, to detect user proximity and provide audible or vibrational feedback when the device is busy, preventing unintended disconnection during data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a visual indicator like a busy light is used to notify users that the device is busy, then the device provides some indication not to be removed, but the indicator may not be visible or clear to users
Solution Approach 1:
The patent transitions from visual notification (2D light) to haptic notification (3D vibration/tactile feedback). The haptic indicator element provides physical feedback through vibration or tactile sensation that users can feel, adding a new dimension of user interaction that is more reliable and noticeable than visual indicators alone.
Solution Approach 2:
The patent replaces the optical notification system (busy light) with a mechanical haptic system (vibration motor or tactile actuator). This substitution uses mechanical vibration to convey the busy state, which is more directly perceptible to users than visual indicators, especially when users cannot see the device clearly.
2Reliability
If the device provides no notification when busy, then the device structure remains simple, but data loss occurs when removed unexpectedly
Solution Approach 1:
The patent introduces a haptic indicator element as an intermediary between the processor and the user. This intermediate component translates the processor's busy state signal into tangible haptic feedback, providing reliable notification without requiring complex notification systems. The haptic element serves as a simple yet effective mediator that enhances data safety.
Solution Approach 2:
The haptic indicator element provides self-contained notification capability within the connectable device itself, eliminating the need for external notification systems or complex host-device communication protocols. The device autonomously notifies users of its busy state through haptic feedback, simplifying the overall system while improving reliability.

Function Achieved in This Case
Ensures user awareness of the device's busy state, preventing data loss by providing clear and intuitive notifications that the device should not be physically removed until the transfer is complete.
