Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a single battery is used to power modular network test equipment, then the device structure is simple, but the power supply duration is insufficient for demanding test applications
Solution Approach 1:
The battery system is segmented into a main battery and multiple removable extended battery modules. Each module can be independently attached or detached from the main battery through electrical connectors, allowing the system to be divided into functional units that can be configured based on power requirements. This segmentation enables extended operation without requiring a completely redesigned power system.
Solution Approach 2:
The extended battery modules are designed to nest with the main battery through mechanical engagement features and electrical connectors. The modules can be stacked or attached in series, with each module containing its own battery cells, circuit board, and connector assembly. This nested configuration allows multiple power sources to work together as a unified system while maintaining individual module independence.
2Power
If multiple battery modules are connected to extend power capacity, then the power supply capacity increases, but the management of charging and discharging becomes more complex
Solution Approach 1:
The battery management functions are merged into the main circuit board of the test device, which communicates with all battery modules through a standardized interface. The system combines the power output of multiple modules and manages their charging/discharging cycles through a unified control algorithm that monitors voltage, current, and temperature across all modules. This central化的 management approach simplifies the user interface while handling the complexity of multiple power sources.
Solution Approach 2:
The battery management system implements feedback control by continuously monitoring the state of charge, voltage, and temperature of each battery module. The system adjusts the charging and discharging rates dynamically based on real-time conditions, preventing overcharging or excessive discharge of any individual module. Feedback signals from the battery modules inform the main controller to optimize power distribution and extend overall system operation.
3Ease of operation
If removable battery modules are designed for easy attachment and detachment, then the ease of operation improves, but the reliability of electrical connection may be compromised
Solution Approach 1:
The electrical connectors are designed with preliminary alignment features such as guide pins, positioning ribs, and keyed interfaces that automatically align the male and female connectors during attachment. The connector geometry is pre-configured to ensure proper engagement of power and data signal contacts before final mechanical locking occurs. This preliminary action prevents misalignment and ensures reliable electrical connection from the moment of attachment.
Solution Approach 2:
The connector design includes built-in compliance features such as spring-loaded contacts, flexible circuit boards, and tolerance-compensating mechanisms that absorb misalignment or stress before it can compromise the electrical connection. These cushioning elements protect against connection failures due to manufacturing tolerances, thermal expansion, or mechanical stress during field operation, ensuring reliable power and data transmission.
