Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple trunk structure is used for storing luggage, then the device complexity is reduced, but the convenience of charging electronic equipment during travel deteriorates
Solution Approach 1:
The charging device is nested within the trunk structure, with the charging cavity integrated into the existing luggage compartment. The sliding cover mechanism is embedded within the trunk body, allowing the charging function to be contained within the existing structure without requiring separate external components.
Solution Approach 2:
The trunk is designed to serve multiple functions: it acts as both a luggage storage compartment and a charging station. The sliding cover mechanism serves dual purposes of protecting the charging device and providing access to the charging cavity, while the charging cavity itself can accommodate various electronic devices of different sizes.
2Loss of time
If the charging device is placed in the trunk, then the device complexity is reduced, but the accessibility and time required to charge the mobile phone increases
Solution Approach 1:
The charging device is pre-positioned within the trunk structure in an easily accessible location. The sliding cover is designed to be quickly opened with a simple motion, allowing the user to access the charging device without having to fully open the trunk or perform complex operations. The elastic lugs are pre-configured to automatically secure the cover when closed.
Solution Approach 2:
The sliding cover mechanism provides dynamic access to the charging cavity, allowing quick opening and closing motions. The elastic lugs provide automatic engagement and disengagement, enabling rapid access to the charging device while maintaining secure closure when not in use.
3Reliability
If the charging device is stored in the trunk without a cover, then the device complexity is reduced, but the security and prevention of the charging device falling out deteriorates
Solution Approach 1:
The sliding cover is nested within the trunk structure, with its movement path defined by the trunk's internal geometry. The elastic lugs are integrated into the cover itself, and the protrusions are formed as part of the trunk's internal structure, creating a compact nested arrangement that secures the charging device without requiring external components.
Solution Approach 2:
The elastic lugs automatically engage with the protrusions when the sliding cover is closed, providing self-securing functionality without requiring additional fasteners or complex locking mechanisms. The elastic deformation of the lugs provides automatic tension to hold the cover in place, and the design allows the cover to be easily opened when needed.
4Adaptability or versatility
If a fixed charging cavity is used, then the device complexity is reduced, but the adaptability to charging devices of various specifications deteriorates
Solution Approach 1:
The bottom of the charging cavity is designed with elastic pieces that can deform to accommodate charging devices of different sizes and shapes. This dynamic adaptation allows the fixed cavity structure to flexibly fit various devices without requiring multiple cavity configurations or adjustable mechanisms.
Solution Approach 2:
The elastic pieces at the bottom of the cavity can change their physical state from rigid to flexible, allowing them to compress and expand to adapt to different device specifications. This parameter change enables a single fixed cavity design to accommodate multiple device types without increasing overall structural complexity.
