Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control parameters are set according to a single battery type, then the printer operates reliably with that battery type, but the output capability of high output batteries cannot be utilized effectively
Solution Approach 1:
The control parameters are made dynamic and adjustable based on the detected battery type. The processor automatically selects appropriate printing parameters (such as printing speed, heat generating element activation, and transport speed) according to the battery's maximum current output capability, allowing the system to adapt its behavior to match the power available.
Solution Approach 2:
The invention changes the control parameters based on the battery type detected. By identifying the maximum current output capability of the battery, the system adjusts printing parameters to optimize performance - using higher printing speeds and more heat generating elements when a high output battery is detected, and conserving power when a standard battery is used.
2Productivity
If the number of heat generating elements is increased to improve printing speed, then printing efficiency increases, but power consumption increases beyond what standard batteries can provide
Solution Approach 1:
The number of simultaneously activated heat generating elements is adjusted based on the battery type detected. When a high output battery is identified, the system can activate more heat generating elements at once to achieve faster printing. When a standard battery is detected, the system reduces the number of simultaneous elements to stay within the battery's power capabilities.
Solution Approach 2:
The system uses partial activation of heat generating elements based on available power. Instead of always using all elements or a fixed number, the system activates only the necessary number of elements required for the desired printing speed given the battery's current output capability, avoiding excessive power consumption.
3Productivity
If printing speed is increased to improve productivity, then output increases, but the battery is depleted faster reducing operational duration
Solution Approach 1:
The printing speed is dynamically adjusted based on the battery type and remaining capacity. The system monitors the battery's maximum current output and automatically optimizes the printing speed to balance productivity with battery conservation, ensuring optimal operational duration for the given power source.
Solution Approach 2:
The system incorporates feedback mechanisms to monitor battery status and adjust printing parameters accordingly. By continuously assessing the battery's state and comparing it against the required power for different printing speeds, the system can make real-time adjustments to maintain optimal performance while extending battery life.
