Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the mobile communications device provides maximum electrical power output through the audio jack, then the fluid testing apparatus can operate, but excessive power input causes printed circuit board heating
Solution Approach 1:
The patent implements dynamic power adjustment by monitoring the power consumption of the fluid testing apparatus and adjusting the audio jack power output in real-time. The system transitions from static maximum power output to dynamic adaptive power output, modifying the electrical parameters (voltage, current) based on the actual needs of the connected device, thereby preventing overheating while ensuring adequate power delivery.
Solution Approach 2:
The system changes electrical parameters (voltage, current) of the power output from the audio jack based on the power consumption characteristics of the connected fluid testing apparatus. By monitoring and adjusting these parameters dynamically, the system optimizes power delivery to match the actual requirements of the device, avoiding both under-powering and over-powering conditions that cause heating.
2Reliability
If the mobile communications device provides sufficient power to the fluid testing apparatus, then the apparatus can operate reliably, but continuous maximum power output reduces battery life
Solution Approach 1:
The patent implements dynamic power adjustment by monitoring the power consumption of the fluid testing apparatus and adjusting the audio jack power output in real-time. The system transitions from static maximum power output to dynamic adaptive power output, modifying the electrical parameters (voltage, current) based on the actual needs of the connected device, thereby preventing overheating while ensuring adequate power delivery.
Solution Approach 2:
The system enables the fluid testing apparatus to effectively control its own power consumption by allowing it to communicate its power needs to the mobile device. The apparatus monitors its own operational state and adjusts the power draw accordingly, with the mobile device's power management system responding to these signals to provide exactly the right amount of power needed, no more and no less.
