Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power consumption of the device is increased due to new functionality, then the device provides improved functionality, but the rechargeable battery needs to be charged more often
Solution Approach 1:
The patent implements dynamic battery characteristics by allowing the battery to operate in different modes (capacity mode and cycle life mode) that can be selected based on user needs. The system dynamically adjusts charging and discharging parameters, voltage ranges, and current limits to optimize either maximum capacity utilization or extended cycle life, resolving the contradiction between power consumption and battery duration
Solution Approach 2:
The patent changes operational parameters of the battery including voltage ranges, current limits, and charging/discharging rates to address the contradiction. By adjusting these parameters, the system can optimize performance for either high power consumption scenarios or extended operational duration, allowing the battery to adapt to different functionality requirements
2Duration of action of moving object
If the battery capacity is increased to provide longer run time, then the battery can power the device longer, but the cycle life of the battery may be reduced
Solution Approach 1:
The patent implements a dynamic selection mechanism that allows users to switch between capacity mode and cycle life mode. In capacity mode, the battery operates to maximize run time by utilizing higher current and broader voltage ranges. In cycle life mode, the system adjusts parameters to extend battery longevity. This dynamic approach resolves the contradiction between run time and cycle life by allowing optimization based on specific usage scenarios
Solution Approach 2:
The patent changes operational parameters including current limits, voltage ranges, and charging/discharging rates to balance run time and cycle life. By adjusting these parameters, the system can optimize for either extended operational duration or increased reliability in terms of cycle life, resolving the contradiction between these two competing objectives
3Use of energy by moving object
If the battery is charged to maximum capacity to extend run time, then the available power is increased, but the battery undergoes more stress and degrades faster
Solution Approach 1:
The patent changes voltage ranges and current limits as key parameters to manage the trade-off between available energy and battery degradation. By adjusting these parameters, the system can optimize for either maximum energy utilization or reduced degradation, resolving the contradiction between these competing objectives
Solution Approach 2:
The patent implements dynamic adjustment of charging and discharging parameters based on selected operational mode. In capacity mode, the system allows broader voltage ranges and higher current to maximize available energy. In cycle life mode, parameters are adjusted to reduce stress on the battery. This dynamic approach resolves the contradiction between energy utilization and degradation
