Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultrasonic diagnostic systems face instability and operational issues when transitioning between separated and docking states due to changes in data processing and communication modes, leading to potential errors and improper image display.
Innovation Solution
An ultrasonic diagnostic system that includes a first device and a second device capable of switching between wireless and wired communication modes, with an immediately-before determining unit to assess the state change and transition to an operation limited state before docking, stopping wireless communication and switching to still image display to prevent errors and ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system allows both separated and docking states for flexibility, then adaptability is improved, but operational stability deteriorates during state transitions
Solution Approach 1:
The immediately-before determining unit detects the immediately-before state of docking in advance before actual docking occurs. Based on this detection, the control unit proactively switches from wireless to wire communication mode and transitions the operation state from normal to operation limited state, preventing communication errors and operational instability before they can occur during the state transition.
2Ease of operation
If wireless communication is used in separated state, then ease of operation is improved, but communication reliability worsens during docking transition
Solution Approach 1:
The system detects the immediately-before state of docking in advance and proactively switches communication mode from wireless to wire before actual docking occurs, preventing radio wave saturation and communication errors that would occur during the transition.
Solution Approach 2:
The wire communication mode serves as an intermediary communication method that takes over before wireless communication fails during docking transition, ensuring continuous and stable data transmission between the probe and main body device.
3Reliability
If the system transitions operation state during docking, then operational safety is improved, but productivity worsens due to operation restrictions
Solution Approach 1:
The system dynamically adjusts the operation state based on the current state transition phase. In the immediately-before state of docking, the operation limited state is activated to ensure safety during communication mode switching. After docking is completed and wire communication is established, the system can return to normal operation state, restoring full diagnostic functionality and efficiency.

AI summary
In the present invention, an FE device and a BE device communicate using two wireless communication routes in a separate state. Approaching of each device is determined in both devices immediately prior to a docking state by monitoring of a wireless communication state. Wireless communication between the two devices is then stopped, and both devices enter a freeze state (operation-limited state). When the docking state is then formed, wired communication is established between both devices. Then, when an unfreeze input occurs, both devices return to a normal operation state. Both devices temporarily enter the freeze state also when a state change from the docking state to the separate state occurs.
