Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote input devices like styluses lack output elements for direct user notification, making it difficult to provide feedback, especially when they exceed the maximum wireless communication distance from connected electronic devices, leading to challenges in visual identification of control success messages.
Innovation Solution
An electronic device with a communication circuit, antenna, wireless charging coil, positioning sensor circuit, and processor is used to detect the attachment and detachment of a remote input device, measure its distance, and provide notifications through a wearable device when the stylus is out of range, utilizing sensors like cameras, infrared, ultrasonic, and RF signals for distance measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If remote input device is used without output elements, then device complexity is reduced, but notification capability to user deteriorates
Solution Approach 1:
The patent introduces a wearable device as an intermediary to receive notification signals from the electronic device and display them to the user. This mediator enables the remote input device to provide feedback indirectly through the wearable device, resolving the contradiction between simplified device structure and notification capability.
2Length of moving object
If wireless communication distance is increased, then remote control capability is improved, but notification reliability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the electronic device detects the distance to the remote input device and sends notification signals to the wearable device when the remote device is out of range. This feedback loop ensures reliable notification delivery even when communication distance exceeds normal limits.
3Adaptability or versatility
If user is spaced apart from electronic device, then remote operation flexibility is improved, but visual identification of notifications deteriorates
Solution Approach 1:
The patent transitions the notification display from the electronic device's screen to the wearable device, which is worn on the user's body. This dimensional change allows notifications to be visible regardless of the user's distance from the electronic device, maintaining visibility while enabling flexible remote operation.
