Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If internal stacking with outer edge zipper seal is used, then card storage capacity is improved, but operation time increases
Solution Approach 1:
The card storage device is divided into multiple independent card trays that can be accessed separately. Each card tray is a distinct segment that can be popped up and manipulated independently, allowing users to access specific cards without opening the entire storage structure, thus reducing operation time while maintaining storage capacity.
Solution Approach 2:
The card trays are pre-arranged in an ordered sequence within the storage device. This preliminary organization of cards by category or frequency of use allows users to quickly locate and access needed cards without searching through the entire storage structure, significantly reducing operation time while preserving storage capacity.
2Quantity of substance
If wallet-type multi-layer storage is used, then card storage capacity is improved, but device complexity increases
Solution Approach 1:
The storage device is segmented into multiple card trays that can be independently manipulated. This segmentation allows for increased storage capacity while keeping each individual tray simple in structure, avoiding the complexity of traditional multi-layer wallet designs where all layers are interconnected.
Solution Approach 2:
The card trays are designed to be dynamically movable rather than fixed. Each tray can be independently popped up and manipulated, providing dynamic access to stored cards. This dynamic design simplifies the overall structure compared to rigid multi-layer wallets while maintaining high storage capacity.
3Ease of operation
If single direction pop-up is used, then ease of operation is improved, but card visibility decreases
Solution Approach 1:
The storage device is divided into multiple independently accessible card trays. This segmentation allows users to pop up only the specific tray containing the needed card rather than opening the entire structure, improving ease of operation. Simultaneously, each tray can be fully opened to provide complete visibility of its contents, resolving the visibility issue.
Solution Approach 2:
The card trays are designed to pop up in a vertical dimension rather than requiring horizontal opening. This dimensional change allows for easier operation as users can access cards by simple vertical motion, and when opened, each tray provides full visibility of its contents in a controlled manner.
4Loss of information
If fan-shape pop-up mechanism is used, then card visibility is improved, but device size increases
Solution Approach 1:
The storage device is segmented into multiple independent card trays arranged in a compact configuration. This segmentation allows each tray to provide full visibility of its contents when opened, while the overall device maintains a compact size because each tray is independently sized and can be accessed separately without requiring a large fan-shaped expansion.
Solution Approach 2:
Cards are preliminarily organized and positioned within each card tray in a compact arrangement. This preliminary organization maximizes the use of space within each tray, allowing full visibility of cards when the tray is opened, while keeping the overall device size compact by eliminating the need for large fan-shaped expansion mechanisms.
