Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices face challenges in providing direct access to wake state functionality from a low power state without requiring additional activation inputs or incurring latency.
Innovation Solution
The system employs co-processors to manage power and operate the display in low power states, allowing direct access to device functionality through the display or input components without an intervening activation input.

Engineering Contradiction Analysis
1Use of energy by moving object
If the device enters a sleep state to conserve power, then power consumption is reduced, but access to device functionality requires additional activation inputs and incurs latency
Solution Approach 1:
The device is segmented into multiple operational states (wake state, low power state, sleep state) with distinct functionality. The low power state acts as an intermediate state that maintains limited functionality while consuming reduced power, allowing users to access common features without full device activation.
Solution Approach 2:
The device performs preliminary actions by maintaining certain subsystems in a ready state during low power mode. The display and processor are partially maintained or quickly reactivatable, so that when a user interacts with the device, the transition to full functionality is faster and requires fewer activation steps.
2Use of energy by moving object
If the device enters a sleep state to conserve power, then power consumption is reduced, but latency is introduced when accessing device features
Solution Approach 1:
The device dynamically adjusts its operational state based on usage patterns and power requirements. The system can transition between wake, low power, and sleep states, with the low power state providing a dynamic intermediate mode that balances power savings with responsive access to functionality.
Solution Approach 2:
The device performs preliminary actions by maintaining certain subsystems in a ready state during low power mode. The display and processor are partially maintained or quickly reactivatable, so that when a user interacts with the device, the transition to full functionality is faster and requires fewer activation steps.
3Ease of operation
If the display operates continuously to provide direct access, then access to device functionality is seamless, but power consumption increases
Solution Approach 1:
Different parts of the device operate with different quality levels based on the operational state. During low power state, the display maintains basic functionality with reduced refresh rates or lower brightness, while the processor operates at reduced capacity. This local differentiation allows the display to provide visible feedback without consuming full power.
Solution Approach 2:
The display operates periodically rather than continuously during low power state, using reduced refresh rates or intermittent updates to maintain visibility while conserving energy. This periodic operation provides sufficient user feedback without the continuous power consumption of full display operation.

AI summary
Direct access to device functionality from a low power state of the device is provided. The direct access can be provided without an initial user input to wake the device or the display of the device before activating the desired functionality. The low power state of the device may include a low power state of the display in which the time is persistently displayed, and may include a low power state or an inactive state of a main processor of the device. The direct access can be provided by detecting a type, location, or other aspects of a user input received while the device is in the low power state.
