Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple mobile X-ray apparatuses are charged simultaneously using separate electrical outlets, then charging can proceed in parallel, but the requirement for multiple electrical outlets increases device complexity and operational difficulty in facilities with limited outlets
Solution Approach 1:
The patent merges multiple charging operations into a single electrical outlet by enabling one mobile X-ray apparatus to charge multiple other apparatuses simultaneously through its power supply device, which includes a power limiter and multiple output ports. This consolidates what would traditionally require multiple separate outlets into a single device, improving productivity while maintaining ease of operation.
Solution Approach 2:
The power supply device is designed with multi-functionality to serve both as a charging device and as a power distribution device. It can simultaneously charge multiple mobile X-ray apparatuses while also providing power output through the same outlet, making the system universally applicable in facilities with limited electrical outlets.
2Adaptability or versatility
If a power tap with increased number of electrical outlets is used to charge multiple apparatuses, then more outlets are available, but the current capacity is exceeded causing overheating or breaker activation
Solution Approach 1:
The power supply device dynamically adjusts the current distribution to each output based on real-time detection. The power limiter circuit actively monitors the total current and dynamically allocates power to multiple outputs, preventing overcurrent conditions that would cause overheating or breaker activation, thus maintaining safety while providing multiple outlets.
Solution Approach 2:
The system incorporates feedback through current detection circuits that continuously monitor the input current and adjust the power distribution accordingly. This feedback mechanism ensures that the total current never exceeds the capacity of the single electrical outlet, preventing safety issues while maintaining adaptability to charge multiple apparatuses.
3Loss of time
If large amount of current is required to charge mobile X-ray apparatuses quickly, then charging time is reduced, but the risk of overheating and breaker activation increases
Solution Approach 1:
The patent segments the charging current into multiple controlled paths through the power limiter circuit. Instead of delivering a single large current pulse that causes overheating, the system divides the power and distributes it through multiple output ports with controlled current allocation, reducing thermal accumulation while maintaining efficient charging speed.
Solution Approach 2:
The system changes the current delivery parameters dynamically by adjusting the current distribution profile across multiple outputs. The power limiter circuit modifies the current parameters in real-time to optimize charging speed while keeping temperature rise within safe limits, preventing overheating without sacrificing charging efficiency.
