Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a resilient tongue with protrusion is used to form a pivot axis, then the container parts can be connected and pivoted, but the closure mechanism becomes complex and expensive
Solution Approach 1:
The invention extracts the essential pivoting function from the complex resilient tongue mechanism and implements it through a simple pivot axis formed by two aligned holes through the container parts. This eliminates the need for springs and resilient elements while maintaining the core functionality of controlled pivoting movement.
Solution Approach 2:
The invention replaces expensive resilient tongue components with a simple, inexpensive pivot axis structure using basic holes and a pivot element. The design prioritizes cost-effectiveness by using minimal materials while achieving the required pivoting action, accepting that the pivot axis is a simple, non-permanent connection suitable for the application.
2Ease of operation
If the second container part is made open on multiple sides for card insertion, then card access is improved, but the container loses structural stability
Solution Approach 1:
The invention introduces dynamic stability through the pivot axis mechanism, allowing the second container part to be stable when closed but movable when open. The pivot axis provides a controlled degree of freedom that maintains structural integrity during the pivoting operation while enabling easy card insertion and removal through the open configuration.
Solution Approach 2:
The container is divided into two separable parts connected by the pivot axis, allowing the second part to be independently opened for card access while the first part remains stationary. This segmentation enables the container to transition between stable closed and accessible open states without compromising overall structural integrity.
3Device complexity
If a simple pivot connection is used without locking mechanism, then the container is simple and cheap, but the pivoting control and positioning accuracy deteriorate
Solution Approach 1:
The invention introduces a pivot element as an intermediary component that mediates between the two container parts. This pivot element, combined with the pivot axis holes, provides precise control over the pivoting movement and positioning accuracy while maintaining the simplicity of the overall connection structure. The pivot element acts as a mediator that enables controlled movement without requiring complex locking mechanisms.

AI summary
A storage container for cards having a first, outer container part and a second, inner container part, wherein the two parts have a cuboidal shape and are connected in a corner region via a bearing such that the second part is pivotable between open and closed positions with respect to the first part and is lockable in these positions. In order to connect the container parts, an assembly pin is used as bearing, which passes through coaxially arranged passage openings in the container parts. Alternatively, balls are arranged rotatably in the second part that bear against a side wall of the first part from the inside and, to lock positions, engaging in a bearing slot in the first part, and/or providing a positioning aid in the second part on an inner side and projecting into the interior, acting in a clamping manner on the card(s) and consisting of an elastomer.
