Solution Overview
Problem
Existing 3D pop-up cards face challenges in constructing base structures that allow figures to be fixed securely to the base card, ensuring trouble-free unfolding, while also being cost-effective and versatile in design.
Innovation Solution
A base structure with foldable base elements fixed to the inner side of the base card using first fixing means, allowing the base structure to be foldable and securely attachable to the base card, and featuring second fixing means for attaching figure elements, with optional electronic elements for light and acoustic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a base structure with multiple base elements is used to securely attach figures to the base card, then the reliability of figure attachment is improved, but the device complexity increases
Solution Approach 1:
The base structure is divided into multiple base elements (first base element, second base element, third base element, fourth base element) that are foldably connected to each other. Each base element can be independently attached to different sections of the base card, allowing the figure to be securely supported across multiple sections while maintaining a relatively simple overall structure through the use of standard folding mechanisms.
Solution Approach 2:
The base elements act as intermediary components between the base card and the figure. Instead of directly attaching the figure to the base card, the base elements serve as intermediate structures that provide secure attachment points (via attaching means) while allowing for smooth unfolding and transitions between folded and unfolded states.
2Ease of operation
If the base structure is made foldable to enable smooth unfolding, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The base structure transitions from a static rigid structure to a dynamic foldable structure. The base elements are connected via folding mechanisms that allow the structure to adapt its shape during operation - remaining compact in the folded state and expanding to support the figure in the unfolded state. This dynamic capability enables smooth unfolding while the folding connections are designed to maintain alignment.
Solution Approach 2:
The foldable base elements are designed to nest together in the folded state, with each base element containing or adjacent to the folding connections for the next element. This nesting arrangement ensures proper alignment and reduces the space required when folded, while allowing smooth expansion when unfolded. The notches and folding connections are positioned to guide proper alignment during the unfolding process.
3Adaptability or versatility
If fixing means are provided on base elements for attaching figures, then the adaptability for different figure arrangements is improved, but the device complexity increases
Solution Approach 1:
The base elements are designed with universal attaching means that can accommodate different types of figures and attachment methods. The same base element structure with its folding connections and attaching means can be used regardless of whether the figure is attached to the first, second, third, or fourth base element, providing flexibility in figure arrangement without requiring different structural components for each position.
