Multi-Foldable Clipboard Panel Hinge Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clipboards are inconvenient for carrying and storage due to their flat design, limited folding capabilities, and issues with paper wrinkling when folded, which affect user experience and privacy.
Innovation Solution
A multi-foldable clipboard with four panels hinged together, allowing for sequential folding to minimize storage volume and maintain a distance between panels to prevent paper wrinkling, enhancing privacy and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the clipboard is designed as a flat-plate structure, then the writing area is large and stable, but the storage volume is large and inconvenient to carry
Solution Approach 1:
The clipboard is divided into multiple panels (first panel, second panel, third panel, fourth panel) that can be folded relative to each other. This segmentation allows the clipboard to maintain a large writing area when unfolded while reducing to a compact size for storage, directly resolving the contradiction between writing area and storage volume.
Solution Approach 2:
The clipboard transitions from a two-dimensional flat structure to a three-dimensional folded structure. When folded, the panels collapse into each other along the hinged connections, converting the large planar area into a compact volumetric form that is easy to carry, thus resolving the area-volume contradiction.
2Volume of stationary object
If the clipboard is folded twice to reduce volume, then the storage volume is reduced, but the gap between boards is too small causing serious wrinkles in paper
Solution Approach 1:
The clipboard is divided into four panels with three hinged connections, enabling more than two folding positions. This additional segmentation allows the clipboard to achieve compact storage volume while maintaining sufficient gap between panels during folding, preventing paper wrinkles by distributing the folding action across multiple joints.
3Volume of stationary object
If the clipboard is folded to reduce volume, then storage convenience is improved, but the writing area after unfolding is limited
Solution Approach 1:
The clipboard consists of four panels that can be folded at three different hinged locations. This segmentation allows the clipboard to collapse into a very compact form for storage while maintaining the ability to unfold to a large writing area, directly resolving the contradiction between storage volume and writing area.
4Device complexity
If a single panel clipboard is used, then the structure is simple, but it cannot be folded to reduce volume
Solution Approach 1:
The clipboard is segmented into multiple panels connected by hinged parts, enabling folding capability. While this increases structural complexity compared to a single panel design, it achieves the desired compact storage volume through the folded configuration, resolving the contradiction between structure simplicity and storage volume reduction.

AI summary
A multi-foldable clipboard is disclosed, including a first panel, a second panel, a third panel, and a fourth panel. The first panel is configured with a clamping means for clamping paper, the first panel is configured to be hinged with the second panel via a first hinged part, the second panel is configured to be hinged with the third panel via a second hinged part, and the third panel is configured to be hinged with the fourth panel via a third hinged part. The first hinged part is disposed on both side edges of the first panel and protrudes from an upper surface of the first panel. With the cooperation of the first panel, the second panel, the third panel and the fourth panel, the multi-foldable clipboard can achieve a small storage volume while ensuring a larger unfolding size, thus improving use experience.
