Solution Overview
Problem
Conventional mobile radiographic image capturing apparatuses face challenges with battery-powered systems, including lengthy charging times, the need for dedicated charging facilities, and limited mobility due to battery weight, which restricts the number of images that can be captured and hinders immediate recapturing or additional imaging in emergency or outdoor settings.
Innovation Solution
A radiographic image capturing apparatus featuring a mobile cart unit with a detachable radiation source and detector, utilizing an electric power supply activator and manager to enable flexible power distribution between the radiation source and detector based on permission, allowing for wireless power transmission and efficient use of batteries, thereby reducing power consumption and minimizing battery usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery-powered mobile radiographic image capturing apparatus is used, then the apparatus can be moved to various locations including outdoor settings, but the battery weight reduces mobility and the charging time is lengthy
Solution Approach 1:
The system divides the power supply into multiple batteries that can be distributed across different devices (radiation source device and detector device). Each device has its own battery, allowing independent operation and eliminating the need to carry a single large battery for the entire system.
Solution Approach 2:
The radiation source device and detector device can function independently with separate batteries. The system is designed to work whether devices are connected or separated, providing universal functionality in both integrated and distributed configurations.
2Adaptability or versatility
If a battery-powered mobile radiographic image capturing apparatus is used, then the apparatus can operate without fixed charging facilities, but the charging time is lengthy and power capacity is limited
Solution Approach 1:
The power supply system is segmented into multiple independent batteries in different devices. This allows parallel operation and eliminates the single-point bottleneck of charging, as multiple devices can be charged simultaneously or operated independently.
Solution Approach 2:
The system maintains continuous operational capability by allowing the radiation source and detector to function independently when separated. Image capturing can continue even if one device needs charging, as the other can remain operational.
3Use of energy by moving object
If multiple batteries are used in the mobile radiographic image capturing apparatus, then the power capacity increases, but the device complexity and power management difficulty increase
Solution Approach 1:
Each device (radiation source device and detector device) manages its own battery independently. The system automatically detects the connection state and power status of each device, eliminating the need for complex centralized power management.
Solution Approach 2:
The system incorporates automatic detection of connection states and power statuses. The controller receives feedback from each device about its battery status and adjusts operation accordingly, simplifying power management through automated monitoring and control.
4Volume of moving object
If the radiation source device and detector device are integrated, then the system is compact, but the flexibility to distribute power and operate independently is reduced
Solution Approach 1:
The system is designed to dynamically adapt between integrated and separated configurations. The connection state can change during operation, and the system automatically adjusts its power management and operational mode based on whether devices are connected or separated.
Solution Approach 2:
The system provides universal functionality in both integrated and separated configurations. Whether devices are connected or separated, the radiographic image capturing apparatus can perform its intended function, providing versatility across different operational scenarios.
