Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stationary control box with cord is used, then power supply is reliable, but portability is restricted
Solution Approach 1:
The system is divided into separate components: a control box with battery and a charging base with battery. This segmentation allows the control box to be portable while the charging base remains stationary, resolving the contradiction between portability and reliable power supply.
Solution Approach 2:
The invention changes the power supply parameter from fixed AC power to rechargeable battery power. The control box contains a rechargeable battery that can be charged from the charging base, enabling portable operation while maintaining reliable power supply through the battery system.
2Ease of operation
If a portable control box with battery is used, then portability is improved, but battery life is limited
Solution Approach 1:
The charging base acts as an intermediary between the power source and the control box battery. It provides a docking station where the control box can be recharged, effectively extending the operational duration without compromising portability during use.
Solution Approach 2:
The charging base pre-charges its own battery before the control box needs power. When the control box is docked, it receives charge in advance, ensuring extended battery life and reducing waiting time for recharging during operation.
3Duration of action of moving object
If a charging base with battery is added, then battery life is extended, but device complexity increases
Solution Approach 1:
The charging base serves multiple functions: it acts as a charging station for the control box, provides additional battery capacity to extend operation time, and can function as a power source when docked. This multi-functionality justifies the added complexity by providing multiple benefits from a single device.
Solution Approach 2:
The charging base combines the functions of a charging station and an extended power source into a single unit. By merging these functions, the system reduces the need for separate charging devices and cables, actually simplifying the overall system despite the added battery component.
4Productivity
If simultaneous charging and operation is enabled, then productivity is improved, but power management complexity increases
Solution Approach 1:
The system uses feedback mechanisms to monitor battery levels and power status of both the control box and charging base. This feedback enables intelligent power management that automatically directs power flow to maintain operation while charging, improving productivity without requiring complex manual intervention.
Solution Approach 2:
The power management system operates autonomously, automatically managing power flow between the charging base battery and control box battery. The system self-regulates to enable simultaneous charging and operation without requiring complex user intervention or manual power management.
