Portable X-ray Detector Control Circuit Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable x-ray detectors have limited battery life due to continuous power consumption, regardless of usage, leading to reduced battery charge and increased costs from frequent battery replacements.
Innovation Solution
A portable detector control circuit with a multi-function switch and detector control module that reconfigures the detector from a high-power operational mode to a low-power sleep mode when not in use, allowing for selective activation and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the portable detector remains fully energized to enable continuous communication with the imaging system, then the detector can be immediately activated for imaging operations, but the power consumption remains high and battery life is continuously reduced
Solution Approach 1:
The detector dynamically adjusts its operational state between fully energized and reduced-power modes based on usage conditions. The control circuit transitions the detector to a reduced-power mode when not in use, and wakes it up when imaging is required, making the power state adaptive rather than static.
Solution Approach 2:
The detector operates in periodic cycles of active imaging mode and reduced-power standby mode. Rather than continuous operation, the detector alternates between these states, consuming high power only during brief imaging intervals and conserving energy during extended idle periods.
2Weight of moving object
If the battery capacity is limited to make the portable detector lightweight, then the detector portability is improved, but the operating time on a single battery charge is reduced
Solution Approach 1:
The detector uses periodic action to alternate between active imaging mode and reduced-power standby mode. By consuming power only during brief imaging intervals and maintaining a low-power state during extended idle periods, the system extends the effective operating time from a limited battery capacity without requiring additional battery weight.
Solution Approach 2:
The system changes the power consumption parameter dynamically based on operational needs. During imaging operations, the detector operates at full power, but during idle periods it transitions to a reduced-power mode, effectively stretching the battery's energy reserves to last longer between charges.
3Duration of action of moving object
If multiple batteries are used to extend operating time, then the battery life is extended, but the cost of operating the portable detector increases
Solution Approach 1:
By implementing periodic operation with extended idle periods in reduced-power mode, the system achieves longer effective operating time from a single battery. The detector remains available for imaging by quickly transitioning from standby to active mode when needed, eliminating the need for multiple batteries or frequent replacements.
