Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional SI sockets are used for charging PEDs, then charging capability is provided, but the limited availability of sockets and need for multiple adapters increases device complexity and logistical effort
Solution Approach 1:
The insert provides a universal charging solution by integrating multiple charging interfaces (AC power socket, USB ports, and wireless charging pad) into a single standardized unit that can charge various PED types simultaneously. This eliminates the need for multiple separate adapters and cables, as the insert handles all charging needs through one standardized interface that can be exchanged between different galley configurations.
Solution Approach 2:
The insert merges multiple charging functions (AC power, USB charging, wireless charging) and storage capabilities into a single integrated unit. By combining these functions, the system reduces the total number of separate components needed, thereby reducing logistical effort while maintaining versatile charging capability for different device types.
2Ease of operation
If PEDs are made freely accessible to passengers, then ease of access is improved, but security and theft prevention deteriorate
Solution Approach 1:
The system segments PED storage and charging into a dedicated, controlled insert unit that is separate from the general passenger area. The insert can be locked when not in use, creating a secure compartment that prevents unauthorized access while still providing controlled access when needed. This segmentation maintains security while enabling accessibility under supervised conditions.
Solution Approach 2:
The insert acts as an intermediary between passengers and their PEDs, providing a controlled interface for device storage and charging. Rather than allowing direct free access to PEDs throughout the cabin, the insert mediates access by providing a designated secure location with controlled entry, thereby maintaining security while still enabling passenger access to their devices.
3Productivity
If multiple PEDs are charged simultaneously using conventional methods, then charging capacity is increased, but weight and cable management complexity increase
Solution Approach 1:
The insert combines multiple charging interfaces (AC power socket, multiple USB ports, and wireless charging pad) into a single integrated unit, enabling simultaneous charging of multiple PEDs without requiring separate cables and adapters for each device. This merging reduces the total cable weight and simplifies cable management while maintaining high charging capacity.
Solution Approach 2:
The insert replaces mechanical cable connections with alternative charging methods, including wireless charging capability. By substituting physical cable connections with wireless power transfer for at least some devices, the system reduces cable weight and eliminates the need for extensive cable management while maintaining the ability to charge multiple devices simultaneously.
4Reliability
If insert is designed for secure locked storage, then security is improved, but ease of access and charging speed deteriorate
Solution Approach 1:
The insert provides preliminary charging action by automatically charging PEDs as soon as they are placed in the insert, before the insert is locked. This preliminary charging continues uninterrupted during locked storage, so when the insert is later unlocked and accessed, the devices are already partially or fully charged. This eliminates the need to unlock the insert specifically for charging, maintaining both security and charging efficiency.
Solution Approach 2:
The charging action continues continuously and uninterrupted even when the insert is in the locked state. The power supply to the insert remains active, allowing PEDs to charge without interruption during locked storage periods. This continuity ensures that security measures do not interrupt the charging process, maintaining both security and ease of operation.
