Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If standard batteries are used in motorized furniture, then the battery pack can be simple and low-function, but the ratio of battery size to stored power capacity is not optimal and capacity cannot be doubled without doubling the size
Solution Approach 1:
The battery pack is divided into multiple individual battery cells (e.g., seven 3.7V cells) that are connected in series to achieve the desired voltage (25.9V). This segmentation allows for optimized power density and flexibility in configuration, enabling high capacity without proportionally increasing overall size.
Solution Approach 2:
The motherboard serves multiple functions: it monitors and regulates each individual cell, manages the entire battery pack, controls charging and discharging rates, and provides user interface functions (LED indicators, buzzer, Bluetooth). This multi-functionality consolidates control systems and reduces overall battery pack size.
2Ease of operation
If standard batteries are used in motorized furniture, then manufacturing is simpler, but usage, troubleshooting, and maintenance become much more difficult
Solution Approach 1:
The motherboard continuously monitors the state of charge, voltage, and health of each individual battery cell and provides real-time feedback through LED indicators. This allows users to easily assess battery status without technical knowledge, simplifying operation and troubleshooting.
Solution Approach 2:
The battery management system automatically balances cell charges, monitors for faults, and manages charging/discharging without user intervention. The system self-regulates to prevent overheating and optimize performance, reducing the need for user troubleshooting and maintenance.
3Reliability
If individual cell monitoring and regulation is implemented, then charging and discharging can be balanced across all cells, but the motherboard complexity and cost increase
Solution Approach 1:
Multiple monitoring and control functions (cell voltage monitoring, charge management, discharge control, user interface) are merged into a single integrated motherboard. This consolidation reduces the number of separate components and simplifies the overall system architecture while maintaining individual cell regulation capability.
