Electronic Device Card Holding Member Overlapping Ejection Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices face challenges in efficiently accommodating IC cards due to limited internal space and fragile mechanisms, requiring careful handling and lacking convenience in card housing.
Innovation Solution
The electronic device incorporates a holding member with elastic material, capable of holding both cards, with overlapping ejection paths and a design that allows for easy card insertion and stable retention, utilizing the internal space effectively and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple card accommodation portions are provided in the electronic device, then card functionality is improved, but internal space is consumed and mechanisms become fragile
Solution Approach 1:
The patent combines multiple card accommodation portions (first and second accommodation portions for different IC cards) into a unified structure where both cards share common ejection paths. This merging approach allows multiple card functions to coexist while reducing the total volume required compared to completely separate accommodation mechanisms.
Solution Approach 2:
The ejection paths are designed to be universal, serving both the first card and the second card accommodation portions. The holding member can hold both cards simultaneously, and both cards share common ejection paths, creating a multi-functional system that reduces space consumption while maintaining adaptability for different card types.
2Reliability
If separate ejection paths are provided for each card, then card ejection is reliable, but device complexity and space consumption increase
Solution Approach 1:
The patent merges the ejection paths for the first and second cards into overlapping common paths. Instead of providing completely separate ejection mechanisms for each card, the design combines them so that both cards can be ejected through shared paths, reducing mechanism complexity while maintaining reliable ejection function.
3Volume of stationary object
If holding member is placed in overlapping ejection path area, then space utilization is improved, but card handling becomes difficult
Solution Approach 1:
The holding member is designed as a movable component that can dynamically adjust its position. It can move between a holding position (where it holds both cards in the overlapping ejection path area for compact space utilization) and an ejection position (where it releases the cards for easy handling). This dynamic movement resolves the contradiction between compact space utilization and ease of card handling.

AI summary
An electronic device includes a first accommodation portion to accommodate a first card, a second accommodation portion to accommodate a second card, and a holding member capable of holding the first card and the second card. The first accommodation portion and the second accommodation portion are arranged so that an ejection path of the first card and an ejection path of the second card overlap. The holding member is located in an area where the ejection path of the first card and the ejection path of the second card overlap.
