Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional card packs are inconvenient for retrieving and placing cards due to small card pockets, leading to difficulty in accessing and storing multiple cards efficiently.
Innovation Solution
A card pack design featuring a housing with a storage cavity, a pushing mechanism, and a cover plate that rotates to drive the mechanism, pushing multiple cards out through a mechanical gear and swing arm system, with a torsion spring for elastic reset and a limit piece for control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the card pocket is designed to be small to stably store cards, then card storage stability is improved, but card retrieval and placement convenience deteriorates
Solution Approach 1:
The patent introduces a dynamic pushing mechanism that transforms the static small card pocket into a functional system. When the cover plate is opened, a pushing rod automatically pushes cards from the compact storage cavity toward the opening, enabling easy retrieval without requiring the user to manually extract cards from the small pocket.
Solution Approach 2:
The pushing mechanism operates automatically based on the cover plate's opening action. The pushing rod is mechanically linked to the cover plate through a pivot connection, so that simply opening the cover plate triggers the automatic pushing action, eliminating the need for users to manually manipulate cards from the compact storage space.
2Quantity of substance
If multiple cards are stored in a compact space, then storage efficiency is improved, but accessibility to individual cards deteriorates
Solution Approach 1:
The patent employs a dynamic pushing mechanism where the pushing rod selectively pushes cards toward the opening based on the cover plate's opening angle. This allows multiple cards to be stored compactly while enabling individual card accessibility through automatic pushing action when needed.
Solution Approach 2:
The pushing rod features a stepped structure with multiple pushing surfaces at different positions. Each stepping surface corresponds to a specific card position, allowing the mechanism to push different cards based on the cover plate's rotation angle, thus providing selective access to individual cards among multiple stored cards.
3Ease of operation
If a pushing mechanism is added to enable easy card retrieval, then card retrieval convenience is improved, but device complexity increases
Solution Approach 1:
The patent merges the pushing mechanism with the existing cover plate structure. The pushing rod is connected to the cover plate through a pivot connection, combining the cover plate's opening function with the card pushing function. This integration approach enables easy card retrieval while minimizing additional complexity by utilizing the existing structural space.

AI summary
A card pack is provided, which includes a housing, a pushing mechanism, and a cover plate. The housing has a storage cavity for storing multiple stacked cards and is provided with an opening structure that communicated with the storage cavity; the pushing mechanism is provided in the storage cavity and is configured to push out the multiple cards from the storage cavity to an outside of the storage cavity; the cover plate is connected to an outer side wall of the housing and is connected to the pushing mechanism; when the cover plate is rotated, the cover plate drives the pushing mechanism to push out the multiple cards from the storage cavity to the outside of the storage cavity. The storage cavity can conveniently store multiple cards. The opening structure facilitates the entry and exit of the cards and plays a role of fixing the cards.
