Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems with multiple interfaces fail to efficiently manage the activation and disconnection of communication means based on communication distance, leading to increased power consumption and delayed communication initiation.
Innovation Solution
Incorporating a presence status detection mechanism to determine if a communication terminal is within or outside a communication range, allowing for the management of communication interfaces to transition between activation, standby, and disconnection states, thereby enabling efficient control of communication means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication interface with longer communication distance is kept active to maintain communication capability, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the communication interface state changeable between active and inactive based on real-time communication distance detection. The system dynamically adjusts the operational state of communication interfaces according to whether terminals are within communication range, optimizing the balance between reliability and power consumption.
Solution Approach 2:
The patent uses preliminary action by detecting communication distance in advance and proactively transitioning communication interfaces to inactive state before power consumption becomes excessive. The system monitors distance and pre-emptsively manages interface states to prevent unnecessary power consumption while maintaining communication reliability when needed.
2Use of energy by moving object
If the communication interface with shorter communication distance is activated only after entering communication range, then power consumption is reduced, but communication initiation time increases
Solution Approach 1:
The patent applies preliminary action by pre-activating the shorter-distance communication interface in advance when the terminal enters the longer-distance communication range. This allows the interface to be ready before actual short-range communication is needed, reducing initiation time while still managing power consumption effectively.
Solution Approach 2:
The system dynamically manages interface activation timing based on detected communication distance. Rather than static activation rules, the system adapts interface states in real-time based on whether terminals are within range, optimizing both power consumption and response time.
3Adaptability or versatility
If multiple communication interfaces work in conjunction simultaneously, then communication versatility is improved, but control complexity increases
Solution Approach 1:
The patent applies segmentation by dividing communication interface management into independent controllable units. Each interface can be independently activated or deactivated based on specific conditions, simplifying the control logic compared to managing all interfaces as a single complex system.
Solution Approach 2:
The system uses dynamic state transitions to manage multiple interfaces, where each interface independently transitions between active and inactive states based on detected communication distance. This dynamic approach simplifies control complexity while maintaining versatility.

AI summary
A communication terminal (10) including a first communication unit (11) and a second communication unit (12) includes a presence status detection unit (13) that detects a presence status indicating whether a distance from a personal computer (50) is inside a communication range where communication is possible or outside the communication range where communication is not possible for each of the first communication unit (11) and the second communication unit (12), and a communication status management unit (14) that, in accordance with the presence status of either communication unit (11, 12) detected by the presence status detection unit (13), causes the other communication unit (11, 12) to transition to an activation state, a standby state or a disconnection state.
