Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple power modules and batteries are used to support different operating components, then the power output requirements for different operating modes are met, but the maintenance cost increases and storage space requirements increase
Solution Approach 1:
The patent implements a universal power module that can support multiple different operating components through automatic detection and adaptive power delivery. The power module serves multiple functions by identifying attached operating components via electrical parameters and adjusting its output profile accordingly, eliminating the need for separate power modules for different operating modes.
Solution Approach 2:
The power module employs dynamic power delivery by continuously detecting electrical parameters of attached operating components and adjusting its output in real-time. This dynamic adaptation allows a single power module to meet varying power requirements of different operating components without requiring multiple static power modules.
2Power
If different power modules are used for different operating components, then the specific power output requirements are met, but the safety risk increases due to incompatible units
Solution Approach 1:
The system implements feedback by detecting electrical parameters of attached operating components and using this information to verify compatibility before delivering power. The power module receives feedback about the attached component's identity and adjusts its behavior accordingly, preventing incompatible units from being powered and thus ensuring safety.
Solution Approach 2:
The electrical parameter detection mechanism serves as an intermediary between the power module and operating components. It mediates the interaction by verifying compatibility through electrical characteristics before allowing power transfer, acting as a safety gate that prevents incompatible pairings.
3Device complexity
If a single power module is used for different operating components, then the maintenance cost decreases and storage space is reduced, but the ability to meet specific power output requirements for different operating modes deteriorates
Solution Approach 1:
The power module changes its operational parameters dynamically based on the detected operating component. By monitoring electrical parameters such as resistance values and switching states, the power module adjusts its output voltage, current, and power delivery profile to match the specific requirements of each attached operating component, enabling a single module to replace multiple specialized modules.
4Power
If manual selection of operating profiles is required, then the power output can be adjusted for different components, but the ease of operation decreases
Solution Approach 1:
The power module performs self-service by automatically detecting the attached operating component through electrical parameter analysis and autonomously selecting the appropriate power delivery profile. This eliminates the need for user intervention in profile selection, making the system easier to operate while still meeting the specific power requirements of different components.
