Card Receiving Structure With Elastic Restraints for Easy Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card processing machines require users to open and close a door to retrieve processed cards, which can be cumbersome.
Innovation Solution
A card receiving system with elastic elements that block cards and move apart to allow easy removal, featuring a frame with a receptacle and slender elastic elements on either side of the opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a door is used to close the receptacle, then the cards are securely contained and prevented from falling or being deposited at an angle, but the user must open and close the door each time cards are removed which is cumbersome
Solution Approach 1:
The invention extracts the door closure function from the system and replaces it with elastic blocking elements positioned within the receptacle. These elements (slender elements 160) are taken out from the door structure and integrated directly into the card stack environment, allowing cards to be accessed by simply pulling them through the opening without door manipulation.
Solution Approach 2:
Instead of using a door that moves from closed to open state to control access, the invention inverts the approach by using elastic elements that move from a blocking position to a retracted position. The blocking function is inverted from an active door closure to a passive elastic constraint that yields when cards are pulled.
2Ease of operation
If elastic slender elements are introduced to block cards, then card retrieval becomes easier without door operation, but the device structure becomes more complex
Solution Approach 1:
The invention employs slender elastic elements (160) that function as flexible blocking components. These elements are thin, elastic bands or strips that can be easily integrated into the receptacle structure. Their flexibility allows them to deform and move apart when cards are pulled, providing a simple yet effective blocking mechanism without complex mechanical structures.
Solution Approach 2:
The blocking function is segmented into multiple slender elements positioned at different locations within the receptacle. Rather than using a single complex door mechanism, the system divides the blocking function across several simple elastic elements (160) that can independently move and yield when cards are retrieved, distributing the functional complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and correct retrieval of processed cards by allowing them to be pulled through the opening, reducing the need for manual door operation and minimizing incorrect positioning.
Implementation Method 1
a slender element (160) which is elastic and which has a first end (160a) fastened to the frame (151) at a top portion of the opening (156) and a second end (160b) fastened to the frame at a bottom portion of the opening
