Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack the ability to automatically adjust power states based on environmental conditions, such as being in a bag or outside of one, which limits further customization of power management features and affects user experience, battery duration, and energy conservation.
Innovation Solution
A device equipped with proximity sensors and motion sensors that determine whether it is in a bag or outside by measuring distance and motion, allowing for accurate detection and adjustment of power states accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the device uses only proximity sensor data to detect bag presence, then the device structure remains simple, but detection accuracy is insufficient
Solution Approach 1:
The patent combines proximity sensor data with motion sensor data to detect bag presence. The processor integrates information from both sensor types to determine whether the device is in a bag, thereby improving detection accuracy without requiring a completely new sensing system.
Solution Approach 2:
The motion sensor, originally designed for motion detection, is also utilized for bag presence detection by analyzing motion patterns. This multi-functional use of existing sensors improves detection capability without adding dedicated hardware for bag detection.
2Use of energy by moving object
If the device transitions to off state when in bag, then energy conservation is improved, but user accessibility is reduced
Solution Approach 1:
The device transitions to a low power state in advance when bag presence is detected, conserving energy proactively. The system prepares for extended storage by reducing power consumption before the user actually needs to access the device again.
Solution Approach 2:
The system continuously monitors sensor data and dynamically adjusts power state based on real-time bag presence detection. When the device is removed from the bag, the system detects this change and transitions back to full power, providing responsive feedback-based power management.
