Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless ultrasonic probes face limitations in operation time due to high power consumption modes like shear wave elastography (SWE) and continuous-wave doppler (CW) modes, and lack of space for a separate power source and reception circuit.
Innovation Solution
A wireless ultrasonic probe equipped with a main power source unit and an auxiliary power supply device, including an auxiliary battery and reception circuit, controlled by a processor to manage power distribution based on operation modes, enabling high power modes like CW and SWE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a wireless ultrasonic probe uses a single main battery, then the device maintains wireless portability and simplified structure, but the operation time is significantly reduced in high power consumption modes such as shear wave elastography (SWE) and continuous-wave doppler (CW) modes
Solution Approach 1:
The power supply system is segmented into two independent power sources: a main battery for basic operations and an auxiliary battery for high power consumption modes. This segmentation allows the probe to switch between power sources based on operational requirements, thereby extending operation time in high power modes without compromising wireless portability.
Solution Approach 2:
The auxiliary battery is designed to serve multiple functions: it can be attached to the probe body when high power modes are needed, and it can also function as an external power supply for charging the main battery. This multi-functionality resolves the contradiction by providing extended operation capability while maintaining the simplified single-battery structure for normal operations.
2Adaptability or versatility
If the internal space of the wireless ultrasonic probe is kept compact, then the device maintains portability and ease of operation, but it becomes difficult to implement a separate power source and separate reception circuit required for operation modes such as the CW mode
Solution Approach 1:
The reception circuit is segmented from the main probe body and placed in the auxiliary battery unit. This segmentation allows the probe to maintain a compact size for portability while still implementing the separate reception circuit required for CW mode and other advanced operation modes.
Solution Approach 2:
The auxiliary battery unit acts as an intermediary component that houses both the auxiliary power source and the reception circuit. This intermediary structure resolves the space constraint by providing a separate compartment for additional functionality without increasing the main probe's volume, thereby enabling versatile operation modes while maintaining compact dimensions.
3Duration of action of moving object
If a separate auxiliary power supply device is added to enable high power modes, then the probe gains extended operation capability, but the device complexity increases with additional components like switches, voltage variable modules, and capacitor circuits
Solution Approach 1:
The auxiliary power supply device merges multiple functions into a single integrated unit: the auxiliary battery, voltage variable module, capacitor circuits, and control switches are all combined in the auxiliary battery unit. This merging approach enables extended operation capability while minimizing the increase in overall device complexity by consolidating components rather than adding separate systems.
