Electronic Device Power Control via Unique Address Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face issues with quick start-up and potential erroneous detection or unauthorized information exchange due to the use of radio waves with low directivity for user proximity detection, and reliance on personal information for user identification.
Innovation Solution
An electronic device with an address acquisition unit that communicates with approaching terminals to shift its power state from a standby to a quick start state when a matching unique address is detected, allowing for efficient power management and secure user-specific information provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If radio waves are used to detect user proximity, then the detection range is extended, but erroneous detection may occur due to weaker directivity
Solution Approach 1:
The patent introduces an intermediary identification mechanism (unique address exchange and matching) between the detection process and the power state transition. Instead of directly transitioning power states based on radio wave detection alone, the system uses the unique address as a mediator to verify legitimate user proximity, thereby preventing erroneous detections while maintaining extended detection range
Solution Approach 2:
The system performs preliminary actions by pre-registering unique addresses of authorized communication terminals before the actual proximity detection occurs. When a terminal approaches, the system checks whether its unique address matches any registered address before triggering the power state transition, ensuring reliable detection
2Adaptability or versatility
If personal information is exchanged for user identification, then user-specific customization is enabled, but unauthorized information exchange may occur
Solution Approach 1:
The patent replaces sensitive personal information with a cheap, non-sensitive alternative (unique address) that serves the same identification purpose. The unique address acts as a disposable identifier that enables user-specific customization without containing sensitive personal data, thereby preventing unauthorized information exchange while maintaining adaptability
Solution Approach 2:
The unique address serves as an intermediary that enables user identification and customization without exposing personal information. It mediates between the need for user-specific settings and the requirement for information security by providing a non-sensitive identifier that can be safely exchanged
3Speed
If power is supplied to all functions in standby state, then device responsiveness is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic power management by transitioning the electronic device between different power states (standby state and ON state) based on real-time detection of user proximity. When a registered communication terminal approaches, the device dynamically switches from standby to ON state, providing full functionality and responsiveness only when needed, thereby optimizing energy consumption
Solution Approach 2:
The system performs preliminary detection of user proximity through communication with approaching terminals and matching unique addresses before fully activating the device. This preliminary action allows the device to prepare for full operation without immediately consuming full power, transitioning smoothly from standby to ON state only when user presence is confirmed

AI summary
An electronic device includes an address acquisition unit that performs communication with an approaching communication terminal to acquire a unique address of the communication terminal, and a power control unit that shifts its own power state from a standby state where power is supplied only to a minimum function to a quick start state where power is supplied to a function other than a presentation function to a user, when the unique address acquired by the address acquisition unit matches a registered address.
