Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display devices receive power from external power sources through power cables, then power supply is stable, but the display devices cannot be disposed away from external power sources and require manual charging
Solution Approach 1:
The display device automatically moves to the cradle for charging when battery capacity is low, without requiring user intervention. The controller autonomously controls the moving unit to navigate the carrier to the cradle position, enabling self-service charging that resolves the contradiction between ease of operation and device complexity.
Solution Approach 2:
The patent replaces manual charging operations with an automated mechanical system. The moving unit uses sensors and controllers to automatically navigate and position the carrier at the cradle, substituting human mechanical actions with automated control systems that integrate sensing, decision-making, and actuation.
2Adaptability or versatility
If display devices have built-in batteries for portable operation, then mobility is improved, but power supply duration is limited and requires periodic charging
Solution Approach 1:
The display device proactively monitors battery capacity and automatically initiates charging operations before the battery is completely depleted. The controller detects low battery states and triggers automatic movement to the cradle for recharging, ensuring continuous operation without interruption and extending the effective usage duration through predictive charging behavior.
Solution Approach 2:
The system implements continuous feedback monitoring of battery capacity through detection units. The controller receives real-time battery status information and automatically adjusts operations based on remaining capacity, creating a closed-loop control system that extends battery utilization by triggering charging actions at optimal moments before complete depletion occurs.
3Ease of operation
If display devices lack battery capacity notification, then device complexity is reduced, but users cannot make informed decisions about power management
Solution Approach 1:
The detection unit continuously monitors battery capacity and provides real-time feedback to the controller and user interface. This feedback mechanism enables users to make informed power management decisions by displaying remaining capacity information, while the controller uses the same feedback data to automatically trigger charging operations when capacity falls below predetermined thresholds.
Solution Approach 2:
The controller acts as an intermediary between the battery detection unit and the user interface. It processes raw battery capacity data from the detection unit, interprets the information, and presents it in a user-friendly format through the display or notification system, while also using this intermediate processed information to make automated charging decisions.
