Solution Overview
Problem
Electronic clocks face challenges in managing communication connections with computers, leading to inefficient power usage and inconvenience due to uniform disconnection times that may not align with user behavior, resulting in unintended disconnections.
Innovation Solution
A communication control system that dynamically adjusts connection times based on the user's behavior patterns, power generation, and charging balance, using a smartphone's advanced resources to determine optimal connection periods and display information in a user-friendly manner, allowing flexible control and power conservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If communication with computer is maintained continuously, then user convenience is improved, but power consumption increases
Solution Approach 1:
The connection time period is made dynamic by determining it based on charging balance information and power generation amount. The system automatically adjusts the connection duration between the electronic clock and computer, transitioning from a static fixed time period to a dynamic adaptive time period that responds to power availability conditions.
Solution Approach 2:
The connection time period parameter is changed based on variations in charging balance and power generation amount. When power generation is sufficient, the connection time period is extended; when power is limited, the connection time period is reduced, thereby optimizing the balance between user convenience and power consumption.
2Use of energy by moving object
If communication is disconnected during night time to save power, then power consumption is reduced, but user convenience deteriorates due to unintended disconnections
Solution Approach 1:
The system incorporates feedback mechanisms by monitoring charging balance information and power generation amount in real-time. This feedback allows the system to make informed decisions about connection timing, ensuring that disconnections occur only when power savings are achieved without negatively impacting user convenience.
Solution Approach 2:
The connection time period is determined in advance based on predicted charging balance and power generation conditions. This preliminary determination allows the system to prepare for upcoming power availability changes, ensuring that communication is maintained during periods when power is sufficient before disconnections become necessary.
3Device complexity
If connection time period is set uniformly in advance, then system complexity is reduced, but adaptability to user behavior deteriorates
Solution Approach 1:
The system performs self-service by automatically determining the connection time period based on its own monitoring of charging balance information and power generation amount. This eliminates the need for complex manual configuration while achieving high adaptability to actual usage patterns and power availability conditions.
