CompactFlash Memory Card Adapter for ExpressCard Slot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users accustomed to the CompactFlash form factor are hesitant to adopt the ExpressCard standard due to its larger size, and existing adapters often eject both the memory card and the adapter when using ejector mechanisms, which is inconvenient.
Innovation Solution
A memory card with dimensions similar to CompactFlash, combined with an adapter assembly that includes a tongue, finger grip, and side rails, allowing it to fit within an ExpressCard slot while disabling ejector mechanisms, enabling secure insertion and removal of memory cards without disturbing the adapter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an adapter is used to enable CompactFlash-sized memory cards to fit in ExpressCard slots, then the look and feel of CompactFlash is maintained, but the adapter may be inadvertently ejected when ejector mechanisms are activated
Solution Approach 1:
The patent extracts the ejector mechanism interaction from the adapter by providing a flat front surface that does not engage with ejector mechanisms. This removes the problematic interaction between the adapter and ejector components, preventing inadvertent ejection while maintaining the compact form factor.
Solution Approach 2:
Instead of designing the adapter to actively engage with ejector mechanisms for removal, the patent inverts the approach by designing a flat front surface that deliberately avoids engagement. This passive design prevents ejection mechanisms from affecting the adapter, solving the retention problem.
2Ease of operation
If ejector mechanisms are used to remove memory cards from ExpressCard slots, then card removal is enabled, but both the memory card and adapter are ejected simultaneously which is inconvenient
Solution Approach 1:
The patent extracts the adapter from the ejection process by providing a flat front surface that does not engage ejector mechanisms. This allows the ejector to remove only the memory card while leaving the adapter in place, simplifying the ejection control and enabling independent card removal.
3Ease of operation
If the adapter front surface is designed to engage with ejector mechanisms, then removal is enabled, but the adapter cannot remain in the slot during memory card operations
Solution Approach 1:
The patent inverts the traditional adapter design by providing a flat front surface that deliberately does not engage with ejector mechanisms. This allows the adapter to remain continuously available in the slot while enabling memory card removal, providing both adaptability and continuous availability.
Solution Approach 2:
The flat front surface design serves multiple functions: it maintains the compact form factor, prevents ejector engagement, and allows the adapter to remain in place during operations. This multi-functional design resolves the contradiction between removal capability and continuous availability.
