Sleep State Control for Wireless Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are not adequately notified when electronic devices, such as digital cameras, return from a sleep state due to communication with external apparatuses unless an application is activated, leading to unnecessary activation awareness.
Innovation Solution
An electronic apparatus with a communication unit and control unit that wirelessly communicates with external devices, returning from a sleep state only if the connection request is from a previously paired device, and remaining in a sleep state if the request is from an unpaired device, thereby minimizing unnecessary activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the control unit returns from sleep state upon receiving any connection request, then communication responsiveness is improved, but power consumption increases due to unnecessary activations
Solution Approach 1:
The control unit performs preliminary verification by checking whether the external apparatus that transmitted the connection request has been connected in the past before returning from the sleep state. This preliminary check prevents unnecessary activations while maintaining responsive communication with authorized devices.
2Adaptability or versatility
If the control unit activates upon receiving connection request, then communication functionality is improved, but user awareness of unnecessary activation deteriorates
Solution Approach 1:
The control unit provides feedback to the user by displaying notification when it returns from sleep state due to a connection request from an unpaired external apparatus. This feedback mechanism maintains user awareness of unnecessary activations while preserving full communication functionality.

AI summary
An electronic apparatus comprises a communication unit that wirelessly communicates with an external apparatus present within a predetermined range, and a control unit that controls the electronic apparatus. Upon receiving a connection request from the external apparatus in response to an advertisement signal transmitted via the communication unit when the control unit is in a sleep state in which its power consumption is reduced, the control unit returns from the sleep state and determines whether or not the external apparatus, which has transmitted the connection request, has been connected to the electronic apparatus in the past, and if determining that the external apparatus, which has transmitted the connection request, has not been connected to the electronic apparatus in the past, the control unit transits to the sleep state.
