Rotatable Card Case Opening for Closed-Cover Card Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card cases are inconvenient for card removal as they require the flexible member to be open for access, leading to disordered storage and unnecessary trouble.
Innovation Solution
A card case design with a flexible member and card box featuring adjustable opening directions for cards or banknotes, allowing parallel or angled orientations to facilitate card removal even when the flexible member is closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible member is used to cover the card outlet to secure cards, then security is improved, but card accessibility deteriorates
Solution Approach 1:
The card case is divided into two independent access systems: the flexible member covering the first card outlet and the card box with push-button mechanism covering the second card outlet. This segmentation allows users to access cards from the card box without opening the flexible member, resolving the contradiction between security and accessibility.
Solution Approach 2:
The card box acts as an intermediary mechanism between the secure flexible member and the user's hand. It provides a secondary access path through the push-button mechanism that allows card retrieval without compromising the security provided by the flexible member.
2Ease of operation
If the card box is added with adjustable opening direction, then card retrieval convenience is improved, but device complexity increases
Solution Approach 1:
The card box is designed with adjustable opening direction that can be rotated to different angles (0° to 355°). This dynamic adjustment capability allows the opening direction to adapt to different user needs and orientations, improving card retrieval convenience while maintaining a relatively simple mechanical structure through rotational movement.

AI summary
A card case includes a flexible member and a card box. The flexible member is provided with a first holding groove and a first opening, and the first opening is in communication with the first holding groove, and a direction faced by the first opening is a first direction; a card box is connected to the flexible member, the card box is provided with a second holding groove and a second opening, and the second holding groove is configured to hold cards or banknotes; the second opening is in communication with the second holding groove, and a direction faced by the second opening is a second direction, and the second direction is parallel to the first direction, or an angle is formed between the second direction and the first direction, and the angle is from 0° to 355°.
